Sandisk Extreme Pro SSD with Bitlocker encryption performance issue

Question: Sandisk Extreme Pro SSD with Bitlocker encryption performance issue

Hello,

first off, I hope I am posting this in the right sub-section. If not, I apologize (and feel free to move it to the relevant section).

My general query is to do with SSDs and Bitlocker encryption.

Description:
I recently upgraded my primary SSD (with boot and OS partitions) from an entry-level Kingston 120GB SSDNow V300 to a 240GB SanDisk Extreme PRO SSD, hoping that I would notice some improvement, if not in real-life usage then at least in benchmarks, despite my primary goal for this upgrade being the increase in disk space.

Issue:
The problem is that not only did I not see any improvement, but the results were worse than before.
The only difference between the two disks is that the first had Bitlocker AES-128 with diffuser, and
the second has Bitlocker AES-256 with diffuser. Everything else in the build remains unchanged.

I understand that moving to AES-256 means taking a hit in performance, but I assumed that the better (and newer) SSD would compensate for this.

I read through all the relevant threads on this forum (like this one) as well as through other sites on the net. My understanding is that software encryption and SSDs (especially those with a controller that is designed for compression of data, like the SandForce on my original Kingston V300) do not go hand in hand.
However, my Sandisk SSD has a Marvell controller, which I take it does better with data that cannot be compressed (i.e. encrypted), so that should not be the issue.

Basically, I do not know what I am doing wrong. All I want is my PC to be encrypted while taking full advantage of having my system/boot drive be on an SSD instead of a HDD.
Do I change the encryption to 256 without diffuser, 128 with diffuser (Windows default) or other?



Following are benchmark results for comparison:

1) Kingston SSD with Bitlocker enabled, 128-bit with diffuser



2) Sandisk Extreme Pro SSD with Bitlocker DISABLED



3) Sandisk Extreme Pro SSD with Bitlocker ENABLED, 256-bit with diffuser



In addition, my motherboard only has SATA II, so that is why the resuls in 2) are lower than one might expect.

Thank you to anyone for pointing out what I am doing wrong or what I should do the fix the problem.

Preferred Solution: Sandisk Extreme Pro SSD with Bitlocker encryption performance issue

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Sandisk Extreme Pro SSD with Bitlocker encryption performance issue

It is slower because the 256bit encryption requires more time on the CPU. The drive may perform faster, but the CPU/Motherboard is the same and it is your bottleneck, not the SSD.

To get better performance from bitlocker, you need to have an eDrive capable SSD.

might sound like a really dumb thing to check but is your sata cable ok? some boards come with different cables for sata 3 connections for example asus come with a black and white cable that has sata 600/ sata 3 on them.

i'm not sure how much of a difference they make if any but just a thought.

I have an older Laptop that operates on  Windows 7 Ultimate,I have the Bitlocker Drive Encryption on and encrypted for Drive C:   I now started the process of encrypting my external usb hdd Drive E: which has a long way to go for it's large

Hi guys,

I'm planning to buy a SSD, the intel ones are too expensive, so i can choose between those 2.

As far as i know the Samsung is superior but some recent issues have started worrying me.

Samsung TRIM error could be wiping data

The 256Gb model is not listed though, i'm planning to use it on windows.

Any suggestions? complaints? Thanks in advance.

I was planning to wait for the 860 series but apparently those are not gonna happen this year (at least not next month). 850 pro series are almost 1 year old.

Answer:Samsung SSD 850 Pro 256 Gb Vx Sandisk Extreme Pro 256 Gb

I have the 128GB and so far no issues. Here's a test from Anadtech on the 850 Pro Testing Samsung 850 Pro Endurance & Measuring V-NAND Die Size

This is a quote from the article:
I found that the current WLC value drops by one after 60 P/E cycles (I ran the test over multiple WLC drops), which suggests that the WLC will drop to zero after 6,000 P/E cycles. In other words, the V-NAND in 850 Pro is good for 6,000 P/E cycles, which is twice the cycle count of modern 2D MLC NAND but quite far away from Samsung's "ten times the endurance" claims. Either Samsung is using lower binned parts in the 850 Pro (i.e. saving the 30,000 P/E cycle parts for enterprise drives) or the WLC value has artificially been limited to ensure that enterprises do not use the 850 Pro and pay the premium for the 845DC EVO/Pro instead.

However, the memory available only registers at 7.82 GB.I've tried formatting it ~ no improvement.I've tried it in my EOS 30D ~ as above - zilch!I've contacted the company (online) from whom i purchased it.

Initially I found that BitLocker on the Go supported removable media like flash drives and external drives. Why isn't a CD/DVD supported since it is considered removable media? Will this support be available in future releases?

Answer:Will BitLocker or BitLocker on the Go ever support CD/DVD encryption?

Hi,
 
Bitlocker to Go is not supported on CD/DVD. Your suggestion is valuable, I will forward this information to the appropriate department through our internal channel.
Both the Microsoft Product Team and Development Team will take into consideration all suggestions and feedback for future releases.
 
Currently, you may need third party software to encrypt CD/DVD.

Good afternoon all,I purchased two 2GB Sandisk Extreme lll SD cards from an online store based in the UK. The packaging seems genuine, and the cards arrived boxed with recovery software and soft storage pouch. Sadly one of the cards has failed, and has been replaced. The replacement card also failed. The card was used in a Nikon D80 camera to take still images. I am unable to delete the files on the card or reformat the card. I have tried this using my Nikon, my compact camera, my desktop XP Pro and my laptop Vista. None of these will reformat the card. The error message from the Nikon is ?This card cannot be used?. Is there a known compatability issue with the Nikon and the card. Is there a way of reformatting the card to use again without sending back to the store. The card is NOT locked. The back of the card has the following information:2.0GBSanDiskBE0710102992BMade in ChinaI am at present using budget 2Gb SD cards in my Nikon and have no difficulty with them at all, although naturally they are slower than the Sandisk card.I would appreciate any advice you may have to offer.

Just received a new Sandisk Extreme Pro USB 3.0 drive, sdcz88-128gb, and write speed is very slow (40 mb/sec)  when connected to the front usb 3.0 ports on my Lenovo K450.  If I use a rear port, which means unplugging other cables so it will fit, write speed is way faster at around 196mb/sec. The device is rated at up to 240mb/sec write speed.
 
Edit: Additional info: Running Windows 8.1 - In Devices and Printers dialog, if mouse is over USB drive thumbnail, it says the device could be faster connected to a USB 3.0 port.  But of course it IS connected to a USB 3.0 port.
 
Here is the really strange part (to me). If I connect my older Sandisk Extreme USB 3.0 64gb drive to the front ports, it works fine at the faster write speed, around 191mb/sec.
 
Is there some driver update that is required to make the sdcz88-128gb able to get full speed on the front USB 3.0 ports?
 
Any other ideas? Or should I just assume something is defective in the sdcz88-128gb?

Since it's the same model number, just different capacities, it seems like it could be defective. Try posting on Sandisk's support forums, or contact Sandisk support.

Answer:BSOD on resume from suspend with sandisk extreme ssd

I developed a waking problem from sleep mode when I changed out my ram to bigger. My Lenovo loses about 600mb of 'something' from memory between entering the sleep mode .. to waking up? I still haven't figured it out. You might want to try changing the memory sleep/suspend setting to just hibernate. You should wake up plenty fast from hibernate on that ssd. If using it.. you might also read up on the intel rapid storage technology. I read that needs uninstall/reinstall sometimes when changing to ssd.

I just recently bought a dv7 7047cl that was a display model. I love the computer. The only non-standard addition is the Broadcom Bluetooth LAN combo adapter that I installed. My problem is this. I just bought my first SSD drive. Its a Sandisk Extreme SSD 240GB drive. I tried to install it but the BIOS would freeze about 9 out of 10 times rebooting the computer. No exaggeration. That 1 out of 10 time it would load and I would try to install Windows. Under standard Legacy settings for the DVD drive it cannot even see the SSD. Under UEFI settings it recognizes the drive and got so far as to install the Windows software but upon the first reboot it froze again. Windows install keeps telling me that there is a 100 MB MBT partition. Windows manager (with the drive hooked up via a USB to SATA adapter) tells me that the drive is healthy and not multiple partitioned. I used DISKPART in admin to clean the drive and on the USB cable it behaves like any other reliable drive. The moment I put it into the computer and hook it up internally my computer acts like its not there. The BIOS disk test tells me that there is no drive there. With my 1TB HDD the laptop behaves wonderfully but the SDD freaks it out. I looked at the maintenance sheet and it said that the computer supports SDDs up to 160 GB. Is that old information or will the BIOS only support 160 GB SSDs? If so, is there a workaround? Can I partition the drive to less than 140 GB and be able to boot from it?... Read more

Hi: Perhaps it is possible that the PC doesn't like the SS drive with the BIOS set to secure boot. I recommend disabling secure boot as well as enabling legacy mode and see if it works that way.

If you are using SD card adapter to insert into the computer SD slot.
At the side, there is a small switch, just either move (flick) up &or down.

Hello, will there every be a BIOS update for Thinkpads (in my case x121e) so that it (the BIOS of the thinkpad) will finally be able to recognize and therefore boot from usb flash drives / sticks like Sandisk Cruzer Extreme??? (Once the OS is running, the drive is recognized just fine, but that's not what I'm here for.) My old desktop pc from 2006 has no problems with such a "modern" drive, but my 5 years younger x121e isn't able to boot from that drive? Come on, Lenovo, you can do better, at least you should...! I'm not sure, if that is the right place for such an inquiry, but as Lenovo apparently doesn't offer a proper support e.g. by email, I just try it this way. I once use the support by phone, only to find out that the lady on the other end had no clue whatsoever of computers and was just looking up answers in her system, which were, of course, not at all helpful. So, for now, this is my only hope, that someone from the technical team at Lenovo reads this and gets the BIOS programmers to work...  Cheers,Mike  [btw: I read about a similar entry where the guy finally marked his problem as solved just because he used another usb stick to boot the first one. That's not a solution, that's a work-around. I'm looking for a solution (= BIOS update), not a work-around!]

Answer:BIOS Update for Thinkpad (x121e) in order to make Sandisk Cruzer Extreme finally bootable?

Hi, I have an x120e and when I get into the BIOS > Startup > Boot, I see the following list:Boot Priority Order1. ATA HDD0 Samsung SSD 830 Series (my main disk)2. USB HDD SanDisk Cruzer Fit (a tiny usb drive that is always attached and holds assorted files)3. USB CD4. USB FDD5. PCI LANThe device can indeed boot from a USB stick. I think you will have to follow this order of events: first attach the USB you want to boot from, yet boot only from your main hard drive, to let the system recognize the attached USB drive and put it in the Boot Priority Order list, then shutdown, restart and get into BIOS. F1: to either to change the ordering in the list to put USB FDD or USB HDD SanDisk first) or F12 (I think): to choose a temp device to boot from. Or....... (another thought), the USB you want to boot from hasn't yet been made "bootable" (I think you may have to go into diskpart > etc to set it active) so isn't recognized in BIOS. I've used a USB flash drive with my recovery partition on it to restore to factory state. That was also a Sandisk Cruzer USB. I've also booted directly into a WinPE sort of environment using another bootable USB made for the purpose of restoring from system images. Mine is an x120e; your x121e can't be much different. Cheers!

Hi,

I have been having some issues when trying to turn Bitlocker on in C:

I have followed the instructions as per this forum to enable a Startup key in gpedit.msc as I dont have TPM which worked.

After following the instructions, Windows Bitlocker asked me to insert a USB to save the startup key to. This appeared to save and then moved onto the next step where I took down the recovery key etc... and finally restarted to make sure my system was compatible before encryption started.

Upon restart, Windows said that it couldnt find a key on the USB drive. After further investigation I found that windows did not save the key to the USB after all even checked as a hidden file. It will save the text file (recovery key) to usb but not the bek file for the startup key.

I have tried this several times but each time it wont save although the system dosent say there has been a problem and moves on to the next stage.

The USB is a 2gb cruzer with the smart drive software removed and re-formatted to NTFS. I have also tried this on other USB drives with no luck and the USB drives work as Iam able to write other things to it?

Any help would be greatly appriciated as I have searched this forum and MS forums with no luck.

Thanks

Hi, I have a problem on my laptop. My office laptop is encrypted using Bitlocker as part of our firm's security over our machines and data stored therein. 
One Saturday, I opened my laptop when it got hibernated last friday night after work. At startup, it ask for my password, I entered it but it showed: "Too many PIN attempts". 
I dont know why and how it happened as I did not change my laptops for the last 3 months since it was issued to me. Since its a weekend, I asked some of our IT personnel having their rest days on how to resolve this, they taught to search for the recovery key
in their database using the identifier provided by bitlocker. I found the files recovery keys but no one matched the identifier showed on my laptop's screen (that cant be accessed).
My question is, what if the recovery keys of my laptop cannot be located anymore, are there ways possible where I can still log-in again losing my files? thanks.

I am having a hard time trying to figure out what encryption method and cypher strength is used on my Bitlocker to go encrypted portable hard drive.

I understand the settings for Bitlocker are configured in the Group Policy Editor but besides that is there any way to see what level of encryption your portable drive has.

When I encrypted this drive, I left the Group Policy settings default when encrpyting the drive which means the drive was supposedly encrypted using 128-bit with diffuser.

This would come in handy when trying to prove to someone that the device is infact encrypted with either 128-bit or 256-bit.

Answer:Bitlocker To Go Encryption Level

Hello Doc, and welcome to Seven Forums.

If the computer does not have Group Policy included to look at, then you can edit (right click on REG file and click on Edit) the REG file downloads in OPTION TWO of the tutorial below, then check the registry and compare it to the REG file downloads to see how it set. By default, it is set to 128-bit with diffuser in Windows 7.

xp encryption seems to work fine for me.

Answer:what's the diff between Bitlocker and the encryption

Win7 has disk imaging software and file backup software in most of the versions, both able to be scheduled. Additionally, there is also an included utility to create a restore CD.

Yes, yes, all of these can be had by excellent third party apps but it is enlightening to see MS finally come around and include more required OS-type utilities with the OS itself.

edit: Woah, my response here was to a completely different post, one questioning the need to upgrade from XP to Win7. Either the mods or the OP significantly changed the original post. Normally I am not that obtuse when replying.

Hey there. I'm having trouble unlocking my external flash drive which was encrypted by me a few months back. It was encrypted using my desktop PC which is not working anymore. I'm trying to unlock it using my laptop.
The problem is, I am entering the correct password but it's marking it as incorrect. I am sure about the password because I had stored it in my phone.

I have a .pfx certificate as well but I really don't know how will it be helpful in unlocking the device. I had saved this .pfx file because while the process of encryption, windows had advised me to save it. Any help will be appreciated. I really need to unlock
this device as the data it contains is irreplaceable.

Regards,
Hannan.

hi hw r u i want to know abt the drive encryption option in windw 7 i used Bitlocker drive encryption to lock or save my drive data(confidential data) frm others. ques is that this encryptn method is right i mean it will damage my hard disk or not . kindly tell me and if u tell me more methods for protection i really appreciate u.thanks

Answer:Bitlocker drive encryption

It will not damage the HDD just make sure you save the "Key" in a save place not on the computer (A hard copy on paper and a digital copy on a thumb drive two backups of the key is best) also the Windows OS partition or HDD can not be encrypted using Bitlocker.

Hi all

bare with me on this, it may sound stupid and have a very simple answer.

I've got a laptop which I currently have Symantec Desktop Encryption installed with C:/ encrypted.
Personally not quite sure if the files it self on C:/ are encrypted or not (I'm able to access my laptop which has the drive encrypted, over the network from my desktop without any issues/error messages to say its encrypted etc)

This is where the possible stupidity comes in. Symantec current has the drive encrypted (Enter password before booting to Windows), but I was wondering if the data it self is encrypted and if not, would it be possible to do this within Symantec (Cant seem to find a way) if not, would Bitlocker be a solution to encrypting the data or will this cause confliction?

On the side as well, I know that Windows has an option to show folders/directories in a different color if they are encrypted, this option is enabled, but none of the directories are coloured, any idea how to get this to work?
Thanks in advance
Josh

Answer:Using Bitlocker and Symantec Encryption

If it said encrypted, it really is. For example, someone detached the hard drive from your system and then inserted that to another computer to read the contents. Symantec will notify a password entry and if there's no recovery key, you won't be able to access it. It works like BitLocker To Go. BitLocker Drive Encryption doesn't need a password prompt if the drive is connected to the original motherboard and there's no changes to BIOS settings or updates AFAIK.

Hello

Thought I'd ask before I do something stupid
I'd like to encrypt my fileservers with Bitlocker but I wonder how fast it is these days? The servers run Windows 8.1 and when trying on another system I get about 100MB reads and writes during encryption - is this somewhere in the ballpark for performance? Oh and the cpu supports hardware encryption as well

Thanks in advance
Edit:

Just finished encrypting a Raid6 array with 8x2TB drives. Time approximately 24 hours and an average speed of about 125-130MB/sec. Cpu is an AMD A4 5300 dual core cpu. Not so bad imho.

While using BitLocker Drive Encryption feature, i selected the settings for using the USB to store the security key. But, once I restarted my PC, BitLocker didn't recognized the USB and went into recovery mode.

Can anyone suggest as to why the USB key was not taken into consideration?

Answer:BitLocker Drive Encryption

Windows Vista didn't provided any means by which a user working on Windows XP could access a shared folder of an BitLocker encrypted drive. But, this feature was provided in Win 7 in the form of BitLocker To Go feature.

So, my question is, isn't it hampers the main motive that was behind BitLocker Drive Encryption feature?

Question: Is it possible to use the command "manage-bde -pause D:" to pause BitLocker encrypting the HDD, which would then allow me to shut down the computer, transport it to my new house, and then turn the computer on and resume the encryption process, without any loss of data or corruption?

I have an internal hard disk drive currently being encrypted (~47%) using BitLocker. In 8 hours time I need to transport the whole PC to a new house where I'll be living permanently, meaning it will need to be turned off and disconnected from the power. Considering the time it has already run I don't think it will complete in time I have available.

If it is not possible to do that I can leave the computer at its original location to complete encryption, the only problem is that there is a large travel distance and the inconvenience of not being able to use my primary computer.

Edit: Forgot to mention that this is an internal HDD used to store downloads, documents, photos, music, and videos. My operating system is stored on an SSD that has already been encrypted.

Thanks in advance!

Hi Everyone!
I have intresting situation that started quite some time ago but now it´s time to fix it :) We are using MBAM in our environment and SCCM to publish windows 10 to computers. So far everything is working. I have not found correct or good solution to deploy
BitLocker in TaskSequence. All manuals are a bit different. So what I did is: I have GPO managing BitLocker requirement. I will just install MBAM client (2.5 SP1) to computers and when user will get computer then after couple of hours MBAM client will require
to insert PIN and it will start to encrypt the drive. So everything works as I want! I like that users can insert their own PIN and it´s not preinserted by administrator. 
Problem is now when computer finish the encryption process and you restart computer. After that computer is asking PIN code (which is correct) and after that it starts Windows Repairing. And it´s not possible to use any repair method (Reset, Restore, Startup
repair etc) - so only option is to format computer. I have noticed that if you encrypt drive before Windows patches then it will survive restart (if it´s working then it´s working!) but if computer will get patches and then you will restart the computer, then
no use - format. 
What can cause the issue and how to fix it? Or maybe there is a good manual how to use MBAM/BL in SCCM TS correctly (if I´m doing it wrong!)...

Hi,

New drive 1gb external, running bitlocker for the first time. Left it overnight cos it was taking forever, (which is the norm)

Woke up this morning and it was stuck on something like 47.1% requesting the bitlocker password, put that in and it starts encrypting again.... But every few random mins it falls over with an error message:

An Error Occurred The System cannot find the file specified.

And prompts me to put my bitlocker password back in, for which I do, and the encrpytion starts again.

Its like at 50% now, after it falling over 3 times in the last 30mins....

I'm not exactly what to do.. I cant sit here for the next 10hrs waiting for it to fall over every few mins asking for the password.

I'd be up for scrapping the whole encrpytion and starting all over again.. But not exactly sure on how to permantely un-crypt the drive and reformat it ? Perhaps running a scandisk before doing so... It was a brand new drive.

I can actually still access the data, because autoplay opens after every error allowing me to see and open the files.

Any suggestions ?

Answer:Bitlocker crashing during initial encryption

TheDoc46, my recommendation is a complete format of the drive. Remove the partitions and then re-create them and then format completely.

Best not to use Bitlocker on an external drive as it is worthless to any other computer due to the encryption technique. Also there are private encryption programs that are just as good like Free Encryption Software - Password Protect Files and Lock Folders

I have installed and set up BitLocker on a Sony VAIO with a TPM 1.2 chip. The drive has been fully encrypted. With BitLocker on, everytime the system boots I get the following message:

Windows BitLocker Drive Encryption Information
The system boot information has changed since BitLocker was enabled.
You must supply a BitLocker recovery password to start this system.
Confirm that the boot changes to this system are authorized.
If the changes to the boot system are trusted, then disable and re-enable BitLocker. This will reset BitLocker to use the new boot information.
Otherwise, restore the system boot information.
ENTER=Continue 
I have tried disabling and re-enabling Bitlocker (disable; reboot; enable; reboot) and get the same message. I have even tried disabling to the point of decrypting and then re-encrypting the whole drive. Neither apporach has worked. According to the BitLocker FAQ, one of the following should trigger the message I'm getting:

Unauthorized changing of the BIOS, master boot record (MBR), boot sector, boot manager, or other early boot components would cause a failure in the integrity checks and keep the TPM-protected key from being released. This is by design because unauthorized modification of any of those components could and should be perceived as an attack. Of course, the BitLocker feature provides methods for authenticated system administrators to update these components if required.
None of that has happened. Any suggestions?

Answer:BitLocker requests encryption key at every boot

When I tested it the setting didn't take effect unless I turned off bitlocker and decrypted the drive then turned it back on with the new setting applied.
I forgot to mention in the last post too, open an administrative commmand prompt. (right click on CMD and click Run As Administrator) and type "gpupdate /force" this reloads the GPO. (it usually take a little while for them to refresh by default.)
An earlier post in this thread states that you just need to apply the new PCR settings and reboot, but from my own testing you really do need to disable, decrypt, enable and encrypt with a new key. The only way I found to speed things up without having to wait for the drive to fully encrypt each time was to skip the test, and right away click on the pause encryption option in the ecryption dialog box. I would then perform my reboot test. I have to do it all again though. A reboot test and a hibernate test. It seems hibernating the workstaion also changes startup information on the computer that bitlocker doesn't like.

I have found manage-bde -w c: to wipe free disk and this is now working ok.

How does Bitlocker work when only encrypting used space - i.e. if I write a file to the disk I assume it automatically encrypts it, but if I then delete that file is the space no longer encrypted and therefore open to hackers?
Look forward to your comments.

If you take a disk and set bitlocker to encrypt only used space it will encrypt the blocks used by the filesystem. If there was some old deleted stuff on the disk when you started that could in theory be recovered. After turning on bitlocker all new files are encrypted. They are not decrypted when you delete them and these deleted files can't be retrieved.







win10freak said:

If you have ever encrypted the whole disk you only need to encrypt used space if re-installing. It will not be possible to retrieve anything from the remaining space on the disk as it was previously encrypted.

Does this mean that BitLocker encrypted the ENTIRE drive?

During the BitLocker setup, I did select to Encrypt the Entire Drive instead of the Used Space option.
I just want to double check if my entire OS drive is encrypted or not.
I assume that when it shows Percentage Encrypted as 100% then I guess it did encrypt the entire drive.

I've searched on the Lenovo's support site, these forums and searched on Google without finding an answer.  These are the procedures I followed to try and enable hardware encryption:- I enabled CSM in order to boot from a USB optical drive with UEFI only enabled.- I booted with a Win 10 Enterprise disk to get to a command prompt and ran the DISKPART clean command in order to put the drive in an unitialized state.- I restarted the laptop and performed a clean install of Win 10 Enterprise- After windows installation, I went back into the BIOS and enabled secure boot which also disables CSM.- After logging back into Windows, I ran the manage-bde command to try and force hardware encryption (mange-bde -on C: -fet Hardware) but I get an error stating that "the drive specified does not support hardware-based encryption."  I know someone will respond with this:For Encrypted Hard Drives used as startup drives:?

New to this forum, and this is my first thread. Please provide me with some help if possible.

So my problem is the following: Kept getting BSODs from some driver inflicting with ntkernel according to whocrashed and bluescreenview. Anyways, disabled my network card as I thought that was faulty, updated all my drivers and checked my ram with memtest just to be sure. Was still getting the BSODs.

Decided to use driver verifier to see which driver that caused this. Bad idea. Turns out that one of the drivers indeed was faulty, but now I'm getting blue screen before I can even log in to windows. Tried to boot into safe mood a thousand times by repeatedly pressing F8 and shift+F8 to no avail. Thought that I then could turn of driver verifier from the command prompt, but No! (Since if I could turn this of the BSOD before system start would then stop since the purpose of windows driver verifier is to force the faulty drivers to create BSOD).

Then downloaded EaseUS Recovery Essentials to see if that could help. Turns out that my ENCRYPTED (bitlocker) which my operating system is on, can't be found because I'm assuming that the change in boot order previously when running memtest disabled it.

Any valued idea on how Bitlocker can be tweaked to decrypt 1TB EXTERNAL HDD faster? It took over 24Hrs to encrypt it 5 months ago. I have decided to decrypt it but seems like it will take it almost the same amount of time it took to encrypt.

Hey guys I have a desktop That has Windows 7 Ultimate edition installed. My parents are having start up issues with the OS. When the OS starts up, Bitlocker Drive encryption Recovery comes up with and option to unlock 2 Drives which is a separate hard drive. it comes up with a recovery key of 4889F7FD. I manually type the key and click the M: Drive which is the recovery OS. It says Error Recovering Disk due to no recovery key. I click Back and it comes up with a different recovery key as F9F25CA2. If both drives have the same password would the recovery key be the same. The bitlocker says I have temparary access but doesnt log me in.

When I go to safe mode, It loads half the files and comes up with the same. Start up recovery cant fix it. when I login to safemode, it loads half the files. Does this sound like a system wipe or can I fix this with a WIndows 7 Disc.

Answer:Bitlocker Drive Encryption OS Start up problem

Hello Zhall, and welcome to Seven Forums.

The key number ID it gives you is only to help you reference what BitLocker Recovery Key is the correct one to enter. I sure hope that you saved or wrote down the actual BitLocker Recovery Key for that drive somewhere in case something like this happens. Without it, you're not going to be able recover the HDD very easily.

Check using the tutorial below to see if you may have the actual BitLocker Recovery Key somewhere, and how to recover the OS drive.

Bitlocker shows as if it is working, but it doesn't require an encryption key on restart. That's a problem I need to have fixed, please. Ever since I downloaded the notification for the Windows 10 upgrade, my computer has NOT been receiving other upgrade
notifications either. I wonder if there was a bug from that installation. I thought it would help you to know my little history in hopes that you could help people like me who have experienced one or more of these issues. Thank you for your attention to this
matter. ~ Burt

Hi folks, I've been trying hard to get my Crucial m500 SSD hard drive to work in edrive (hardware encryption) mode with the w520. I've read several other threads related to the process for different Lenovo machines, but I haven't seen much discussion on the topic for the W series laptops as of yet. Here's what I've tried so far: Clean install of Windows 8.1, while running the latest bios 1.42.All updates from Windows Update toolAll updates from Lenovo System Update EXCEPT the "Intel Rapid Storage AHCI Driver". This seems to be a major point in other threads since apparently the Intel driver is incompatible. I confirm that I'm running Microsoft's "Standard SATA AHCI Controller".Enable drive bitlocker encryption.Link to image When I enable bitlocker encryption, I'm given the choice to either do the existing data only or the whole drive. According to Crucial tech support, that's a telltale sign that edrive is not being used. As further confirmation, I've also run checked edrive status using this method: Start Command Prompt as Administratormanage-bde -statusCheck "Encryption Method" line. It will read "Hardware Encryption" if edrive is in use. Mine says "AES 128"  Moderator comment: Image(s) converted to link(s).

Answer:bitlocker edrive hardware encryption on w520 with ...

W520 BIOS doesn't support eDrive.  I highlighted in red the reason why, from the below URL.  At the time W520 was developed this protocol (and UEFI 2.3.1) didn't exist yet.  We don't have any plan to retrofit the older systems to add this support now.
 
http://technet.microsoft.com/en-us/library/hh831627.aspx
 
For Encrypted Hard Drives used as startup drives:

The drive must be in an uninitialized state.
The drive must be in a security inactive state.
The computer must be UEFI 2.3.1 based and have the EFI_STORAGE_SECURITY_COMMAND_PROTOCOL defined. (This protocol is used to allow programs running in the EFI boot services environment to send security protocol commands to the drive).
The computer must have the Compatibility Support Module (CSM) disabled in UEFI.
The computer must always boot natively from UEFI.

Hi everyone I am new to this forum. I have a question:
1. I had some confidential data stored on a partition that is not encrypted.
2. I decided to give away my computer to charity so I deleted this confidential data using a simple delete in Windows 7.
3. After that I formatted the whole hard disk and then turned on BitLocker and encrypted the whole drive and then gave away the PC to charity without using a disk wiper program .

My questions is: Is it possible for anybody to recover those deleted files using a data recovery program? I understand that when you do a simple file delete only the address of the data is deleted but not the data itself. If I encrypt the drive, files deleted before encryption do they get encrypted because they are not really deleted?

XTS-AES 256 uses 256-bit encryption vs 128-bit encryption with XTS-AES 128. 256 is more secure.

Hello,I am attempting to use BitLocker on my X61 Tablet ThinkPad but have run across an error message that is preventing me from initializing the BitLocker encryption. The message reads as follows: "Your system is not configured to use BitLocker Drive Encryption. If there is a bootable CD or DVD in your computer, remove it...if the problem persists, contact the computer manufacturer for BIOS upgrade instructions." I have run the BitLocker Drive Preparation Tool which has created its own boot drive (S and that program tells me that all is in order.  Additionally, I have verified that I have a fully updated BIOS.There is no bootable CD or DVD in the computer but there is what I assume to be Lenovo's Recovery software on a hidden and unalterable drive that appears in Disk Management. I cannot make changes to this drive; it is labeled only as"Healthy" and "EISA Configuration."Is this recovery drive the culprit that is preventing BitLocker from working? And if so, can it be disabled or BitLocker tricked into functioning while it is still present?Thanks for your help!Jay Fox

Although I'm an Admin on my Win 10 Pro system (Surface Laptop), I can't access the subject menu. Instead, I receive the SysAdmin notice, as in the screenshot. This seems like a new "feature," as I could access it from my previous Win 10 Surface. I suppose that I could make myself a System account, perhaps with PsTolols, but is there an easier way? I can access the submenus in the screenshot, e.g., Suspend protection. Maybe there's really nothing to access, but what what settings are "managed by the SysAdmin? Thanks.

I am trying to create a Windows 10 image for my organization, and cannot figure out one particular issue with Bitlocker. It seems that after I sysprep, and throw the image on a new computer, it then has BitLocker partially enabled. What I mean is that when going to the About page in System in the settings it shows in red "You need a Microsoft account to finish encrypting this device". The C: drive also shows an opened lock with a warning icon (exclamation point in a triangle).

When going to the Manage Bitlocker page is shows an option to turn on bitlocker. Searching various sites on google has led me to the idea of turning on bitlocker, then turning it off again before sysprep. This does in fact disable BitLocker, however it appears to turn on again after imaging on a new computer.

While it's not a huge pain to disable BitLocker afterwards it does take several minutes to decrypt and multiplied that by many computers does eat up a bit of time in the end. Is there something I'm missing here to make sure BitLocker remains disabled after imaging? These are generally on Microsoft Surface Pro 4 computers that this happens on, it did not do the same thing on an HP laptop I tested.

HI all
Im desperate, my Iomega 1tb external hdd has been encrypted and somehow windows autolocked it , now whenever the drive is installed freezes up, and if it passes to the part of the password key, bitlocker stops responding all together. I have tried connecting
and disconnecting several times but its always the same thing, Bitlocker encryption drive stops responding
please assist me here
thanks

Answer:Bitlocker encryption is not responding when unlock key is entered

 
 
Hi,
 
To troubleshoot the issue, I suggest you restart the machine in Safe Mode and plug the external encrypted drive on the machine, and then type the password key again.
Does the window freeze up now? If not, please restart the machine in Normal Mode and perform a
Clean Boot to check the result.
 
Otherwise, I suggest you plug the drive on another Windows 7 machine and unlock it. Does the issue persist? If not, please run a Check Disk and move the drive back
to the original machine.

I just installed Win10 Pro and I love it.
When I enabled BitLocker, I selected to encrypt the Entire drive instead of the Used Space because I just feel I am safer with encrypting the entire drive. And my drive is not new. It had Win7 running before.

So I did a clean install of Win10 pro with BitLocker enabled to set to encrypt the ENTIRE drive.
The encryption process took 7 hours to complete on a 300GB internal disk drive

When I had Win7 (and even Win8.1), it did not take that long to encrypt and I have the same exact internal drive.
In Win7, the whole process took 1 hour. And with Win8.1 took a bit more time, but not 7 hours...

Why is entire disk encryption takes this long on Win10?

And also, I do not have a whole lot of programs installed. I have like 6 programs installed and there not that huge in size.
Thanks!

Answer:BitLocker Encryption process VERY Slow on Win10

win10freak said:

I don't know why this is, but it is ULTRA SLOW indeed. I recently bought a WD Blue 4 TB drive and Bitlocker is already encrypting it for more than 50 hours and is still at only at 68.3%.

According to the Windows Taskmanager the Bitlocker process is using the drive at 100%, constantly reading off and writing on it at 7-15 MB/s. I don't know about the mechanics of a harddrive, but running at 100% for 75 hours (>3 days!) isn't going to improve its health.

I chose the offered new encryption XTS-AES.

In the past, encrypting a whole drive always took some time, but even with drives as big as 3 TB it never took more than 24 hours.

I guess it is some kind of bug and i hope that Microsoft will fix it.
