At first, I don't need to recover my data, I just want my drive back to re-use it.
How can a format my usb drive including all boot sectors which sees to be locked/write-protected by bitlocker?

My problem starts with decrypting my drive by deactivting bitlocker on it by entering the valid password/recovery key. At 36% of decryption the process halts without reason. Now, I'm unable to access my drive or resume the process.

I tried... format with windows
   ..remove with diskmgmt
   ... remove with diskpart
   ... repair-bde
   ... manage-bde
   ... ubuntu live cd
   ... mass production tool software, to override the whole stick

nothing worked. The only thing which worked was once the software M3 Bitlocker recovery Free, but just one time to access the locked partition. But, as mentioned I don't need to recover my data. With that tool I'm not able to wipe the drive.

That Bitlocker protects my data till the end is good, but that it breaks my data and my hardware in such a case is not fair.
How can I break the write-protection mode to finally wipe the hard drive?

I had a drive that was encrypted with bitlocker. After changing the drive and restart I noticed there were only two of the drives that on them Windows installed and another drives changed to free space.
Bitlocker encrypted drive was 100G and another drive 244G. Drives I converted to a drive then format it to restore my data. All the information was not encrypted, was returned but encrypted data was not returned even one bit.

can i undo quick format and decrypt ???
sorry my english is not good.
someone help me please.

Answer:Can i recover lost data from encrypted drive by Bitlocker

BitLocker is not the cause of failed to recover files.Format a drive will clear all data saved on the hard disk. Thus recovery formatted data will be a hard disk based technology but not related to operation system. There is no build-in data recovery feature in Windows operations. So we will needto use third party recovery tool or contact third party data recovery company for current issue.

As recovery missing data service will be expensive, we can also check emails and contact friends to see if that can help get a part of files back especially for photos, documents etc.

how can I recover data from a damaged disk (not physically) of an external encrypted Bitlocer.
Description of the situation:

After connecting the drive - I can decipher it by typing the password - but when you try to open the contents of the report the message "format disk"
- the disk probably has some volume damaged - it has been disconnected from the computer (without being turned off)
What I have done so far:

Using the "Lazesoft" program - I managed to copy (of course after entering the password
on the damaged disk)
the content to another external disk (full - looking after size) but -
this data is encrypted (mainly ending with .ER)
I am asking for a hint:

whether the data that is on the new disk can somehow read (on this disk I can try) [or/and]how to create a damaged disk image to try on another disk [or/and]how to repair a damaged disk (as a last resort) - I am afraid of total data loss [or/and]what other program to use to copy data from a damaged disk
but decrypted

I'm not sure what has failed, HDD or OS, but we really need to recover important data, and I'd be grateful if you could help. I'm writing on behalf of my brother, it's his laptop/HDD that needs to be restored/recovered.

It's a Sony Vaio VGN-AW110J laptop running Windows Vista Home Premium.

The system used to get stuck when moving a picture from desktop into a folder, and a Restart would get the computer working again. The problem with moving pictures into a folder persisted for some time, maybe a couple of months. Kaspersky and IObit Malware Fighter were run several times, no threats were found.

So once, when the system got "frozen" again, my brother was in a hurry and put the computer to Sleep instead of Restarting it, hoping it would be back to normal upon "waking up."

When he tried to turn it on again, it just wouldn't start. Nothing he tried has worked so far. The OS seems to be missing, it's not listed anywhere in any options when booted with F8.

He has put the HDD into an enclosure and connected it to an HP computer running Win 8. As soon as the USB is connected, the HDD starts working/spinning, a progress bar is displayed on the screen, it seems as if the Win 8 were trying to find data on it. This progress bar gets to about 96-97% and then stops forever.

At this point, all we can do is to Safely Remove the drive. First time, the Safely Remove worked. The second time, it would say the Pro... Read more

Answer:HDD or OS failed, need to recover data

Greetings, Leucine, and welcome to MajorGeeks.

I would try Option #2 first - I may be wrong but it just seems that any operation involving drive partitioning stands a better chance of losing/destruction of data.

That "sda2" reference is interesting. You might try booting the machine to a live Linux distro to see if the drive can be accessed - if so, then you may be able to transfer any important data to a flash drive.

Also: you don't happen to have the Microsoft Vista installation disk handy, do you?

Be patient: MajorGeeks is staffed mainly by volunteers so sometimes it takes a while to get the ball rolling. I'm sure other MGs will jump in soon with suggestions.

Specs: P4 1.6, 640 RAM, 30 G, Inspiron 8200
The Dell folks will replace the hdd still under warranty; but, the data wasn't backed up recently.

Computer left on overnight, in the morning BSOD (unknown error message, I'm afraid). User turned off the computer and when turned back on no primary hard drive found and no optical disk found.

Tried connecting the cd-rom, or just the hd, thinking the motherboard, or cable is bad/loose but it's a lappy and can't get the cover off. Dell indicated the optical disk would be recognized if the HD was present.
Suggestions greatly appreciated.

I bought my first serious PC two and a half years ago from Evesham. Athlon 2700, 512 RAM, 120 GB HD, big video card for games. I never had a problem and began to use it for everything. Cos it all seemed so easy I never got into the habit of backing up my HD. A few weeks ago my HD got a little weird, going slow and a bit noisy. Then it started saying there was insufficient memory to run certain programs, (eg game). Then last week it refused to boot up displaying the message ?A Disk Read Error Occurred. Press CTRL+ALT+DEL to restart?. I spoke to Evesham support who diagnosed a hard drive problem and suggested reformatting the drive with the recovery disk supplied with the PC. Strangely he did not warn me that this would erase all data on the disk but having looked through this forum I had learnt that and queried him. He then suggested trying instead to recover the drive using the recovery disk, and if that did not work then taking the PC to a computer shop for data recovery. Following his instructions I tried the recovery using the CHKDSK /R command but this did not work ? after checking 33% of the disk it stopped saying there were on or more unrecoverable errors on the HD. I tried to check the directory with the DIR command but it only returned an error message. I took the drive to PC World in Tottenham Court Road and they tried to open the drive and recover any data they could. After a couple of days they told me that nothing they had tried had worked.

Answer:Hard Drive has failed – can I recover data?

"Is it really true that all this information can be lost?"Yes (that's why everyone bangs on about backups)"Surely if I have the drive there is some way it can be read and recovered??"There are specialist data recovery services that can dismantle the drive and read the disks - they will almost certainly cost an arm and a leg. If you want to go down this route, please ask again. There are some data recovery programs you could try - but you will really need to get your drive into another functioning system before you can sensibly try to run anything to try and read it. Such activities are not for the faint.hearted, and with respect, unlikely to be successful unless you can sit with someone who knows a fair bit about systems. By remote control via this forum, I would honestly hold out little hope.You can search with google for professional services, and get a few quotes - and you can likewise search for hard drive data recovery programs.

I have a dell M1530 XPS laptop with Vista. Yesterday the computer froze and I rebooted, but when it came on it went to some computer utility screen to repair the computer cause it would not reboot (some new vista program). I went through all the steps, it could not repair itself or revert to an old saved point.

Dell guys says the hard drive has failed and is sending a new one, but I have important data on there. It seems like this is a software or corrupt file error. I tested the RPMs and everything on the hard drive and it is fine. It failed the read tests. He suggested using data savers to recover data, but it looks really expensive and I dont think I need it.

If I connect this SATA HD to a usb 2.0 converter and plug it into another computer, do you think it will work so I can recover my files? It might be just an issue with a windows file and won't allow it to reboot. I dont hear any noises coming from the HD and think it is running fine.

Any help would be appreciated!! How much are recovery services anyway? If they do or don't have to open up the hard drive?

Answer:PM8 Resize Partition Failed recover data loss

You can try running a live Linux disk - Ubuntu for example - that may be able to let you see your data and let you recover it to an external drive. Repartitioning a drive is a risky thing to do at any time - with important data on it is suicide, as you've discovered - I suspect even PM would have warned about backing up data beforehand.If there were errors at the start of the process then there is likely to have been a problem with the drive itself, so you may need to budget in replacing that as well."I've always been mad, I know I've been mad, like the most of us..."

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 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.

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

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 have Windows 7 installed and i use a 4GB memory card for private files. The problem is i used Bitlocker encryption, which was working fine until i installed windows updates. Now this mrning i cannot access the memory card at all. It just says drive not accessible although it does recognise that the drive is there. I have tried system restore which also at the moment will not restore to any point. Can anyone help me with this problem please.

Answer:Bitlocker encryption problem

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.

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.

what's the diff between Bitlocker and the encryption in windows XP?

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.

Novice Question, folks...
If I have already encrypted my data with BitLocker or some other encryption software, will that render ransomware ineffective?  Or, does it mean my already-encrypted data just gets another layer of encryption (i.e., double-encrypted)?  

Answer:Ransomware vs BitLocker (or any other encryption s/w)

Hi there,If your data is already encrypted then a crypto ransomware would just add its own encryption over the data, making it double encrypted as you said.

Hi Everyone!
I have intresting situation that started quite some time ago but now its 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 its 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 its 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 its working then its 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 Im doing it wrong!)...

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 ran the manage-bde -status command of my encrypted OS Volume Drive and it shows 100% 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.

Now what if I had chosen to encrypt the Used Space only, then would it still show as 100% encrypted ?
Or am I wrong?

Thanks in advance

I tried several times to encrypt the entire disk after reinstalling Windows 10 but it always took for ever (usually 10 hours) to fully encrypt my internal 320GB drive. I managed to run bitlocker successfully by encrypting only used space. My question is should I run cipher.exe /w to wipe all unused space as this is an old laptop?

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.

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.

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, thendisable and re-enable BitLocker. This will reset BitLocker to use the new boot information.
Otherwise, restore thesystem 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.

Bitlocker hardware encryption with edrive won't enable to a myimage.wim image.

It goes directly to software encryption.

It worked once using Macrium reflect, but never again.

I used the MS recommended way to apply it to an image and that reverts to software encryption too!

I am using an Intel Pro 2500 series SSD drive. Hardware encryption works on a fresh DVD install test.

I then do the following:

1. I clear the TPM in BitLocker, in BIOS too, and turn-off BitLocker,

2. Boot using a PE drive and DISKPART the drive with the clean command

3. Use the Intel SSD tools to remove OPAL activation with a -psid_revert

(I have tried reversing steps 2 and 3 too)

4. Do a fresh 8.1 PRO install

5. With no updating or anything I use sysprep to OOBE and generalize with a shutdown

6. Boot to the PE drive and use dism to apply the Capture-Image script

7. Use DISKPART to clean the drive

(have even used a brand new drive too)

8. Use CreatePartitions-UEFI.txt script to create the partitions

My questions is: Is it possible for anybody to recover those deleted files using a data recovery program?

If I encrypt the drive, files deleted before encryption do they get encrypted because they are not really deleted?

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.

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

Hello all, my issue first originates with going through the windows 8.1 store app to upgrade windows 8 -> to windows 8.1.
"turn off bitlocker because it isn't supported in the edition of windows you want to install"
I am not sure whether i encrypted the drives after installing windows 8 or in windows 7, nevertheless i do know the encryption passwords to the drives.
The biggest problem is therefore trying to remove/disable the encryption to upgrade.
The Applet in the control panel is missing for some reason and so I ask for help here.
I have seen some guides which rely on this applet which is usually situated between auto play and colour management.
I would like to remove/disable the encryption for the upgrade, or confirm the idea that if i disconnect the two drives that are encrypted i could upgrade the OS to 8.1 and wouldn't need to worry about the encryption.
The concern is that the 8.1 OS would not read the drives hence the upgrading message.
My specs are this , related to Bitlocker:
Windows 8 64bit - standard (non-enterprise, pro)Hard drives:1 X 128GB SSD - C:/ windows installed here ** NOT ENCRYPTED **1 X 2TB HDD - D:/ + E:/ **ENCRYPTED**1 X 3TB HDD - F:/ **ENCRYPTED**

Answer:Win 8.1 Upgrade: Bitlocker Encryption Control App Missing

To turn off bitlocker:

BitLocker Auto-unlock - Turn On or Off in Windows 8

Also through an elevated powershell command you could try:
Disable-BitLocker -MountPoint "C:"
Hope that helps!

Hi guys,

I'm seeking full-disk encryption software. I want to encrypt the volume that my Windows installation is on.

First of all, does Bitlocker come on the home edition of Windows 8.1? I recall on previous versions it was only available in the Pro editions.

However, I would prefer to use an open-source disk encryption solution. I've searched but I have not found any that can encryption the Windows installation volume, the ones I found (such as TrueCrypt) can only set up additional encrypted partitions which is no good for me.

Anyone got any ideas or solutions they would recommend?

Thank you

Answer:Full Disk Encryption - alternative to bitlocker

Hi DiskCrypt, Welcome to EightForums.

Bitlocker doesn't come in the home edition as far as i am aware.

TrueCrypt Can't do full disk encryption in windows 8 (It can on windows 7 - Encrypt and Decrypt - Add to Context Menu - Page 2 - Windows 7 Help Forums)

If i get chance i will see if i can find an alternative for Windows 8 Home edition tomorrow.

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.

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)

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.

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

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

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.

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

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.

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

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.

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.
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.
