Question: BitLocker Encryption on External Hard Drives

Recently upgraded to Windows OS 8.1 Pro and cannot encrypt my HP external hard drive. Encryption pauses and states that disk has errors and please run chkdsk. Ran chkdsk and no errors found. Had no difficulty encrypting the C drive with the OS. Any suggestions?

Preferred Solution: BitLocker Encryption on External Hard Drives

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 (This link will automatically start a download of Reimage that you can save to your computer.)

I volunteer for a Charity in the main role of IT admin. Part of what I want to do is ensure the Laptops, External Drives and Memory sticks are encrypted, but I am worried if I (try to) encrypt a drive with files already on, they will get messed up. I am not an expert, so would appreciate any advice and guidance anyone can give. Any favourite products? We are a charity so want to pay little or nothing for this. The intention is to ensure any personal information we hold is secure if it falls into the wrong hands. I am clearly looking at making sure no-one uses Laptops/Ext drives/memory sticks that do not belong to the charity when working (self included), but am a little uncertain where to start with this and do not want to make things worse. Any input gratefully received. Probably a simple question for lots of you, but not for me!!

Answer:Encryption of hard drives, external drives and Memory sticks

All the encryption programs I know of support encrypting drives with data. BitLocker and Vercrypt(TrueCrypt port) absolutely do. BitLocker absolutely requires the use of strong Windows passwords as it only protects the drive if its removed or accessed via another boot device. VeraCrypt has the added benefit of having a pre-boot password so you cannot even boot to the operating system without entering the password. You should still of course have strong passwords and automatic locking of the system after a set time of inactivity.

You may also want to re-evaluate the need for USB drives and sticks, not only are they bad for data security but also easy to lose, have stolen, or just fail. Central storage and VPN access may be preferred to a giant pile of external devices that some places end up relying on.

First off, Bitlocker has never been used on this computer. All its drives have never been encrypted. The problem is that when I open Bitlocker Drive Encryption in the Control Panel there are absolutely no drives listed at all. The area under the heading "BitLocker Drive Encryption - Hard Disk Drives" is completely blank, as is the area under "BitLocker To Go". However, Windows Explorer detects all hard and removable drives just fine.

I have tried the following:

1. chkdsk /r (no problems found)
2. sfc /scannnow (no problems found)
3. rebuilding the MBR with Comodo Cleaning Essentials (which didn't quite like the one I had) after aswMBR found no problem
4. repairing/resetting file and registry ownership and permissions to defaults using SubInACL scripts for registry and for files. (This did fix a few minor nagging problems I had, by the way)
5. a clean boot
6. anti-malware scans (including several offline rescue CD's like Kaspersky, Comodo, ESET and AVG)
7. creating a new user account with admin privileges and trying from there
8. trying to trace file and registry activity with Sysinternals Process Monitor (but I don't really understand what to look for, or what most the results in the listing mean, good or bad)
9. A repair installation/inplace upgrade after a clean boot (this was a problem)

My external hard drive (2TB Toshiba USB 3.0) with BitLocker To Go encryption was accidentally formatted using Windows ?Quick Format? option.  My PC is running Windows 7 Home Premium.

I do have the following details in relation to the BitLocker encryption for this drive;
- BitLocker Recovery Key
- Full Recovery Key Identification
- BitLocker Password

Is there any way to restore the external drive to the ?pre-format? state so that I can recover/access the data?

The drive is in a good health, ? always removed safely by ejecting from notification area and chkdsk has no errors, ? unfortunately data wasn?t backed up as I was in process of migrating to new PC and accidentally deleted the master back-up .

So I had the power go off while I was running bitlocker (to go?) on my external hdd.
I was not able to pause it before this happened.
I was also running BL on an internal drive.

Both were interrupted.
I was able to resume and finish the internal drive.
I was Not able to resume the external.

The BL application just stop responding when I try to resume/unlock the disk.
It also seems I can't restart the machine normally when BL is trying to unlock the drive.

I read somewhere on the ms support site that even with power failure, resuming is possible.
This might have only applied to an internal drive.
I do recall seeing the pause button for the external, with a note that I needed to pause to stop in case of data corruption or something like that.

Is there a way to recover my external?

Do I need to let the program "not respond" for the same time or maybe longer than the time it spent encrypting it?
Could I remove the drive and make it an internal?

Answer:Why are portable external hard drives more expensive than desktop hard drives?

Why are portable external hard drives more expensive than desktop hard drives?Click to expand...

It should be obvious once you think about it for a second. Portable drives are encased in an enclosure. The enclosures must provide power and a data interface for the drive, and connections to the computer. The enclosure cost money to design and manufacture and then someone or some assembly process must install the drive in the enclosure.

The desktop drive has no enclosure and the power and data connections are supplied by the computer.

Yes - as a secondary (not boot) drive.

Where would I find the best deal on a portable hard drive? Any brands I should avoid?Click to expand...

Shop around. Check out Newegg or Tiger Direct or Amazon.

When it comes to enclosures, the drives themselves are all comparably reliable. The problem comes with the enclosures. Not all are equal or offer the same interfaces. I would look for one that supports eSATA and/or USB 3.0.

Answer:Internal hard drives being marked as removable for BitLocker To Go

Now I have Windows 8 on my physical machine. My internal hard drives, connected to SATA ports on the motherboard, are being recognzied as removable drives, as if they're a USB stick or something. Because of this, the option to unlock the drive alongside

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.

Answer:External hard drive has to be opened from bitlocker

Hello Jenieragav, and welcome to Eight Forums.

I'm afraid that if you have do not have the password or recovery key, then about the only option is to format the drive to be able to use it again. That's what BitLocker is designed for. No access with password or key.

Hello all,

I didn't use my external hard drive for over a month, and today I decided that i wanted a back-up of some of the stuff on my laptop. I plugged it in and immediately a message popped up, saying that this drive was protected by something called BitLocker. It required me to enter a 48 digit recovery key. I had NEVER heard of BitLocker up until that point. I didn't know anything about a recovery key, and why didn't it ask for a regular password first, before asking for a recovery key? I didn't have a clue. I still don't have a clue. I searched my computer for BitLocker using the regular 8.1 system search. No results. I searched in PC Info. There is something about encryption there. That was, and is turned off. Not a mention of BitLocker anywhere. When i looked it up it said it comes with Windows 8.1 Pro or Enterprise edition. I am fairly certain I have regular 8.1. How in the name of all that is holy did I get saddled with this piece of shit encryption that locks me from my files, while I don't even want it? When I plugged it into my fathers laptop, also running 8.1 it gave the same message. When i plugged it into my brothers Asus tablet with keyboard combo, also running 8.1, it didn't give any problems. Does anyone here have any clue what is going on? Would be greatly, greatly appreciated.

Thank you

Answer:BitLocker and External Hard Drive(WD My passport 2TB)

I'm having the exact same problem. I've been dealing with it for months. Both of my external hard drives had this happen to them at roughly the same time, and I have no idea how. I too had never heard of Bitlocker before this happened. I tried calling WD and they told me to call Microsoft as Bitlocker is owned by Microsoft. I called Microsoft and they told me to talk to WD. I've been led in circles for months and still cannot access my hard drives and the files on them. I do not have the recovery keys and do not know how to get them. I have been searching for answers throughout the internet without any results. I was told that I could reformat them, and that might work, but then I would lose all of my files. I don't have a backup for them because my hard drives were the backups (that's why I had two!). If you have been able to fix this problem, or have any sort of solutions or options, please, please help me out.

Yesterday I discovered my computer will no longer read my flash drives, external hard drives or SD cards.  If I plug in any of them, they don’t even show up in Disk Management.  In Device Manager they will show up, but will have a yellow flag and under Properties it says the driver for this device is not installed even though they’ve been used before on the computer.  Clicking “Update Driver” doesn’t help because it searches and says there are no drivers for this device.  If I go to the “Events” tab, it gives the  date and “Device configured (null)”.
I restarted my computer today, hoping it might correct this problem, but when restarting I ended up with a message about an inaccessible boot drive.  After going into a loop several times where it told me about the inaccessible boot drive and then restarted again, I finally ended up with a screen that gave me more options for troubleshooting such as doing a system restore point.  I had the computer perform a system restore and finally it took me to the welcome screen and then desktop.  Anyway, rebooting did not correct the problem about my computer not reading my flash drives, external hard drives or SD card.  Any ideas?  Maybe the problems I’m having are related to a recent Windows update (computer seemed to be working fine before the update), but don’t know for sure.

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.

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.

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.

cant think of anything off hand to help with your immediate problem but for future have you tried the yo-safe feature in win locker in win 7 it gives u drive you can hide so no one even knows its there and even someone who knows abt yo-safe cant get into it as when you open the yo-safe it asks for your password you can make your password the same as your master password when windows starts or you can give it a different password.

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

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.

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

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.

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.

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.

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.

Just got a WD elements external drive, 120GB. My father has two computers at his business, and he has not backed them up. A failure of one of the computers means he wouldn't be able to perform day-to-day operations, so a clone of the hard drives is vital.

So I did a little bit of googling, but there isn't one freeware solution that people recommend. I've partitioned it into two equally sized, 55GB partitions. The hard drives that are to be backed up are both 40GB. Anyone know which software is best for cloning the hard drive? I'm comfortable with using command line if need be.

Answer:Cloning multiple hard drives to one external hard drive?

For small single operations I use Clonezilla LiveCD. It's not command line based, but it is text user interface based, so it looks kind of old school. It works great, though.

If you want to get crazy and set up a dedicated box for this, FOG (Linux based, requires a Linux install and a stand-alone computer to act as a server) could do the trick too.

I'd start small with Clonezilla LiveCD and if you want something heavier duty, check out FOG. I use both almost daily. Both are free/open source as well.

As with anything else, do a ton of testing on a practice machine so you get the feel of it. It sounds like this data is critical, so don't use a production machine as your guinea pig to feel out the software.

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!)...

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 bought their pro version which I really like, no financial connection, just a satisfied user.

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.
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.

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!

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?

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.

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.

Hi all,

After almost losing most of my data I want to start a good back-up routine.

My computer has two internal 3TB hard-drives. I have ordered two external USB 3 3TB hard-drives.

I thinking about buying HDClone 'Standard Edition', but I want to make sure it's right for me before I buy.

I want it to be a completely exact copy.

Does HDClone clone 3TB hard-drives? (I saw that some software only clones hard-drives up to 1TB)

Do you think I should buy it?


Answer:Cloning two 3TB hard drive to two 3TB external hard drives

Remember that Cloning means the Target Drives are PRECISELY "the same OR larger" than the original drives. If the original drivers are 2,974,442 formatted and the Target drives are 2,974,308, you MAY have problems. It doesn't take a lot to be 'smaller', in other words.

Before I plan on software, I make sure the drives fit this important criteria.

I can test out some freebie stuff (Macrium Reflect is one example, or if I'm getting Seagates or WDs, they often include a clone-capable package themselves). I don't want to discourage buying good software - I find the best packages have extensive partitioning services, too - making smaller or larger partitions based on Actual Usage rather than some synthetic boundary.

We do a lot of cloning for Boot SSDs, and our practice is to buy two identical drives. Build one up, load all the software, let the user mess it for a few days, then clone it to the 'cold' identical unit. And then make the users switch that 2nd drive for actual usage. If there's a problem, then the original's intact.

Since your 3Tb drives probably aren't your boot drives but are 'just data drives', I wonder about the time spent cloning instead of "just copying what I want to save" directly.

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.

My Labtop is asking for Windows Bitlocker Drive Encryption every time I start it.I do not have the key so cannot use my labtop.Please can some one help ?BjstonzPapua New Guinea

Answer:My Labtop is asking for Windows Bitlocker Drive Encryption

If you didn't encrypt the drive, then who did? You can try F11 to reset the PC back to day 1 but all data will be lost.How do you know when a politician is lying? His mouth is moving.

I have Win 10 Pro and I set the Encryption method in Group Policy as being XTS-AES 256 instead of the default XTS-AES 128. Is XTS-AES 256 more secure than XTS-AES 128?

Answer:New BitLocker Encryption Settings in version 1511?

Hello win10freak,

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

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.

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.

Answer:BitLocker Encryption process VERY Slow on Win10

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.

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.

Now had to find my win8 installation CD to force it into safe mode alternatively to re-install it, but to no avail. It says that the hard-drive is still locked even though I've got the key in a USB stick attached to the computer and even though I manually put in the recovery key. Was now to... Read more

Hello, I have a Lenovo X1 Carbon 4th gen Type 20FB, 20FC. It has a LITEON L8H-256V2G for an SSD. I've tried to get Bitlocker to hardware encrypt to no avail. I want to find out if this particular SSD is capable of hardware encryption (edrive). 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:? 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 securi... Read more

Answer:Bitlocker Hardware Encryption on X1 Carbon with LITEON SSD

I am not sure it will ever work for you.  The SSD has to have a firmware that supports the eDrive functionality.  I believe that Lenovo stopped producing those a few years back.  Please, check this thread for details: I got it working on my old ThinkPad Yoga, and the detailed description can be found in that thread.  But I had one of the last SSDs with eDrive firmware. Best regards, Karol (joe_e_e)

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?
