Migrate Bitlocked NVMe disk on T470

Q: Migrate Bitlocked NVMe disk on T470

Hi, I have a T470 with a Toshiba NVMe disk and recently bought a Samsung 970 Pro in order to replace the original one. I put the two drives on another computer but the original drive seems to be bitlocked. So, I put the original drive back to check for the bitlocker status. Here is the info from the manage-bde -status command: Disk volumes that can be protected withBitLocker Drive Encryption:Volume C: [Windows][OS Volume]Size: 237.23 GBBitLocker Version: 2.0Conversion Status: Used Space Only EncryptedPercentage Encrypted: 100.0%Encryption Method: XTS-AES 128Protection Status: Protection OnLock Status: UnlockedIdentification Field: UnknownKey Protectors:Numerical PasswordTPM How am I going to clone the drive? Do I need to disable any protection before starting the process? Or am I just going to put the two drives together and run a clonning software? Any suggestions for a software?

Preferred Solution: Migrate Bitlocked NVMe disk on T470

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.)

Hi, I have a T470 with a 256G M.2 NVME 2280. I need more storage space and not performance. (SATA III SSD) performance is ok for me. I already have 1TB SATA III 2.5 SSD drives. How can I used these 2.5 SSD drive in place of M2. NVME? Thank you in advance

A:T470 M.2 NVME 2280 to 2.5 SATA SSD downgrade

The SSD should be able to be installed without any problems. The M.2 SSD is currently plugged into the 2.5 "slot via an adapter, which should be removed before changing.

Planning to upgrade the T470 with an SSD and trying to decide between  Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD: https://www.amazon.com/gp/product/B00OAJ412U  For an extra $86, I could get this drive, adapter and cable:Samsung 960 EVO Series - 250GB PCIe NVMe - M.2 Internal SSD (MZ-V6E250BW)https://www.amazon.com/Samsung-960-EVO-Internal-MZ-V6E250BW/dp/B01LYFKX41 https://lenovo.encompass.com/item/11093685/Lenovo/01AX994/Ct470_Adapter_Hdd_Asm_Brackethttps://lenovo.encompass.com/item/11093086/Lenovo/00UR496/Cable_M.2_Ssd Apparently, the 960 EVO would give me about 2 to 3 times faster performance than the SATA SSD. Which one would you guys choose if it were you considering the usage is mainly coding and watching videos? Any insights would be great.

That depends.  Are we spending your money or mine?
Given your use case I'd probably use the extra $ to go with a 500GB 2.5" SSD.  Then again, I'm a spec snob and might not be able to resist the NVMe drive.
As you've already figured out, the 470 only uses 2 PCIe lanes so that limits the NVMe SSD to something like 1700MB/sec.  The SATA unit would be more like 500MB/sec or so.  In practice, you'd probably never notice a difference.

Before removing the HDD from my T470 I made a Clonezilla image.  I then installed the Samsung 960 and restored the image.  Unfortunately upon booting into Windows I was greeted with "Your PC ran into a problem and needs to restart", so that did not work.  I have done many Clonezilla images and restores, but not between two completely different drive technologies.  So if anyone has been able to get this to work with either a T470 or similar laptop, what cloning software did you use, and did you do it with an image backup/restore, or direct clone with the HDD connected to the laptop with either a SATA to USB, or SATA to USB-c cable (If that's the case what cable worked OK)..

Hi everyone, I recently bought a T470 and it came with a Toshiba 512GB Nvme drive (I think its XG4). Just wondering if those of you with this drive are using the default windows drivers or the drivers made for the OCZ-RD400 drive as shown in this thread (https://www.win-raid.com/t29f25-Recommended-AHCI-RAID-and-NVMe-Drivers.html).I have read some comments on how there is poorer performance on this drive compared to the Samsung PM961 drive and I was wondering if you guys have noticed the same with the T470.Thanks for your input

I own a T470 with a Lenovo branded 256GB NVME drive, running Windows 7. The drive is thnSn5256gpuk according to device manager. Looks like this is a rebranded OCZ XG3/4 drive. --- I am getting fairly inconsistent write performance on this drive. According to both crystaldiskmark and as benchmarks, the write performance will sometimes be 700mb/s, other times 300mb/s. I can run the test once, it will show up 700mb/s, run again, and it will be 300mb/s. --- I have tried switching over to the ocz nvme windows 7 drivers, which work just fine btw. But to no avail, microsoft nvme drivers or the ocz ones, both have the same symptoms. --- Anyone able to get consistent write performance from this setup? --- NOTE: Please don't sudgest upgrading my bios, flashing the newest firmware on the ssd or making sure write cache is enabled in device manager... Or any of the low hanging fruit... I've spent about 5 hours trying to get proper (as per the spec of the drive, from the toshiba site) write performance on this drive.

My new purchased T470s laptop (Serial Number: PC0S7E53 Machine Type Model: 20HGS24J00) is equiped with a 256GB PCLe SSD. The SSD is neither Samsung nor Toshiba. It's called LENSE20256MSP34MEAT2A ?! I don't even know how to search the specs of such part, as there is totally no information for such ssd in Google! But the key point is the SSD obtained a relatively low write speed compared with other NVMe SSD. As shown in test record by crystaldiskmark, the write speed is only 160 MB/s. Is this normal? Is it possible to ask for a change of SSD? Because my purchase is still within 7 days. Also, the battery is not that long-lasting as it claimed to be (10.5 hours). I charged until 100% and use the laptop for document reading with some online search in Wikipedia. The battery performance has been set to "better battery" and I didn't play videos and music in the process. The battery runs into 17% in 4 to 5 hours. Although I didn't expect it will hit 10.5 hours, but it is too much beyond that???? Could everyone help me with this? Is it normal or is that any possible solutions? Thank you!

Our church secretary's computer is about 11 years old, and I'm trying to keep it going a couple more years. I have installed a network card and configured the system for DSL internet access, installed a slightly more modern video card and widescreen monitor, and I have upgraded the original Windows 98 OS to XP Home. Problem is, after all the upgrades the original 20 gig HD is just about full. I purchased a new 160 GB hard drive and tried to copy from the old to the new drive using Ghost 12.0. However, the copy failed. The system recognizes the new drive and I can read and write from and to it, but I cannot boot the system from it. I would really like to be able to move the OS and all important data to the new hard drive as I really don't know how much life is left in the old one. There is no important data on the new drive (aside from the unsuccessful Ghost copy), so I can wipe it and try again if need be. Any suggestions for making the next attempt turn out more successful than the first?

A:How to Migrate OS to new Hard disk.

Hi Theog,
Thanks for posting this step-by-step tutorial. It is very helpful indeed. As usual, just a few questions...thanks for your time.


(1): When cloning the data in the HDD to SSD, will Paragon delete all the hidden partition in the SSD? THis is because the SSD's manufacturer has created a hidden partition to store its firmware in it. I am afraid Paragon will wipe out this hidden partition (with the firmware in it).

(2): What does step 8 means for
"Remove free block between partitions?"
Does it mean Paragon will shrink the size of the copied partition in the SSD to remove any free space?

(3): What if i want to maintain the same partition size in the target SSD? Hence, i just need to choose:
Copy options >>> Partition raw copy.
Is that the correct option?

I'm trying to replace my 500gb hard drive with a 480gb SanDisk Extreme SSD. I've done it before with my desktop, but this is my laptop, so I can't dual boot with different SSDs.

The HD is divided into two with a "vanilla" W7 OS+Office etc, and a W7 and audio programs, and I'm using "Dual Boot Pro"

Paragon Migrate to SSD copied the first partition, but there's no way to copy the second. It just wants to clear the disk again. I'm also a bit confused about Alignment. Would it effect this ?
I changed the ACHI setting using the command line OK

Could I just clone the disk using Acronis TI Home, and not worry about the alignment etc ?

A:Migrate old Win7 to GPT disk, dualboot with Win8 possible?

Hi there
If your computer is NOT UEFI capable then you won't be able to BOOT from a GPT drive.

However to multi-boot just DISABLE PROTECTED BOOT if it's on your system - you don't have to disable UEFI.
Backup your OS('es) first just in case it all goes pear shaped.

Simply install the OS'es -- install to different drives / partitions so at boot time just select which you want to boot via BIOS -- or install something like BCD to give you a boot menu.

IMO unless you have really good reasons for wanting to dual boot I'd recommend installing one of the OS'es as a VIRTUAL MACHINE -- however that's your call.

I have written this thread originally in JustLinux Forum. In view of the fact that it may be useful to MS Windows users I have re-written it to suit the non-Linux users. The method can be used on a healthy system or just to salvage data off an unbootable system.


Step 1 – use Linux dd commands to clone the original disk to the new bigger hard disk (only two terminal commands and one of which is optional)
Step 2 – use Gparted or Parted Magic to resize the partitions to absorb the extra space (Optional if you want to use up the spare space in the larger hard disk)

Theoretical consideration (User not interested in the theory can skip the black section and go straight to the blue text

With hard disks getting bigger in capacity and selling cheaper per Gb many PC users can now afford to upgrade the hard disk to a bigger unit. Migrating an operating system to a different hard disk can be hazardous because the integrity of the filing system and the boot loader may be affected in the new home. However if the basic rules are adhered to then the migration can be effortless.

This thread is written to show how to use a Linux Live CD, of either Gparted or Parted Magic, to clone from a smaller source disk into a bigger target disk.

I migrated my Win 7 OS from my 'C' drive to a OCZ Vertex 4 256Gb SSD. No problems, everything works fine.

But recently I was in 'Disk Management' and couldn't make sense of what I was seeing:my SSD was showing as drive 'H' with a capacity of 931Gb!

Depending on which tool I use, I get slightly different reports (Belarc: Disk Management: CrystalDiskInfo)

Anyone ever had similar confusion? and what did you do?

Probably doesn't help that when I reuse old hard disks, I usually leave Windows on them.

As I say, everything is working fine, but clearly there is some confusion around and I don't like that.

I want my reporting software to give me accurate information.

I have my O/S disk ( C: ) sepeated from My Applications disc ( D: ) . Then I store all my Data on other Harddrives.

I want to upgrade my applications disk to a larger capacity, but I worry about maintaining the integrity of Disknames (IDs) so I won't have to re-install all my Applications again.

My plan is to make an Image or Clone of the Apps disc on the New HD and then change the Name of the Apps disk ( D: ) to new name ( Z: ) . Then I would need to reboot, before naming the New Apps disc as the new D:

My worry is the effect of rebooting without any Apps disc at all.. and would everything work after renaming the new Disc back to D: and making a final reboot?

Any advice of steps and procedure to make this work will be greatly appreciated.

Also.. advise on which program to use to make the image/clone would also be helpfull.


A:Advice on Steps to Migrate Apps Hard drive to larger Disk

Your strategy is sound, as is keeping Apps and Data on separate partitions. One way you could approach it is:

1) Image the Apps drive (storing the image to a different drive, of course)

2) Shut the system down, remove the Apps drive.

3) Install the new drive

4) Restore the image you made to the new drive. Drive letter shouldn't be an issue in that case, but if it is, simply change the drive letter as necessary in Disk Management.

Even if you have to change the drive letter to regain the original Apss drive letter, there should be no problems with the apps being usable (once the drive letter is the same as the original).

As for imaging programs, I highly recommend Acronis True Image, but not the latest versions (2010 & 2011), as there have been many complaints regarding those versions. Instead, you can buy version 2009 on ebay for a fraction of the price. Contrary to what some may say, 2009 is compatible with both 32 & 64 bit win7.

That said, if you have a new system or a new motherboard, 2009 may (or may not) have issues with the HD controller (i.e., not see the HDs).

If you'd rather not go the 2009 route, you could always download the trial version of 2011 and see how it works on your system. Be sure and create the Acronis rescue disk if you do try 2011.

I recently bought an M.2 PCIe NVMe adapter for my ADATA XPG SX8000 256GB m.2 NVMe SSD (I only have one M.2 slot on my mobo, which is being used by another, smaller capacity, ADATA XPG SX8000 SSD). I installed the SSD on the adapter card and then inserted the adapter into the PCIe x4 slot. When I went to Disk Management in Windows, it does not show up at all (no new unallocated disk shows up). The weird thing is that it shows up in Device Manager just fine.

Any ideas what's wrong?

Attempted fixes: I've looked in my bios for any options to enable but nothing is there that helps; I've taken it out and put it back in; I've run a memory diagnosis; rebooted multiple times; looked for drivers (there are none)

Recent changes: Just a new video card, which was added at the same time. It's a brand new system on a brand new mobo.

up until windows preview build 14986, the pcie driver "Mobile 6th Generation Intel(R) Processor Family I/O PCI Express Root Port #5 - 9D14" (v10.1.1.27) correctly detects the "Standard NVM Express Controller" storage controller and the Toshiba THNSN5512GPU7 NVMe disk attached to it. starting with windows preview build 15002 (and 15007), the included pcie driver has troubles detecting the storage controller - during bootup, it is detected 4 times, with each time on a different device id. subsequently, the drive is also added 4 times, resulting in boot controller errors & timeouts and failed sleep mode/shutdowns. the included chipset driver in these latest builds seem to have been bumped to v10.1.1.33. the problem can easily be replicated by using unmodified recovery boot usb sticks made from the official isos, and then checking in a recovery console. it is thus not related to anything installed in my system.

I have a drive on my computer that I encrypted. When I rebooted my system (reinstalled OS and everything), I lost the ability to unlock the drive.

I have my recovery key, but it won't let me access any of the files, and I'm not being prompted to type in a password or anything when trying to view the files. I open the file to unclick the drive encryption, but it just says that I do not have access to the file, which is odd because I am the admin.

How can I remove that encryption after a reboot?

A:Bitlocked drive before reboot

Since the OS was re-installed and the method of unlocking the drive was with the previous install, you're out of luck.

The only thing you can really do is format the HDD and hope that nothing important is lost.

Tip: Set a password that will alow you to unlock the drive, just in case you re-install windows.

I only installed Win 7 Ultimate yesterday and have been playing around investigating features. I decided to install Bitlock on an external USB drive.
I did this from within Help & Support. I've got a password and I've got a Bitlocker Drive Encryption Recovery Key. The encryption started and was immediately paused and now I can't go backwards or forwards. It wont let me do anything.
In Manage Bitlock almost everything leads to the message "The BitLocker metadata for the encrypted drive is not valid. You can attempt to repair the drive to restore access" but I can find no way of doing so.
In windows explorer I can see all the files on the drive but if I try to copy them to another drive I'm told the files cannot be found.
Obviously I need assistance.
This is my first post in this forum so if I'm in the wrong place please redirect me. Thanks.

A:Problem with Bitlocked USB External HDD

I just did the samething. Bitlocker froze during the encryption at 90%. I found a way to get my drive back and functioning.
1.Restart windows with drive inserted.
2.Go to Manage Bitlocker
3.Turn off Automatic Unlock
4.Remove USB Drive and reinsert into slot
Now when it ask for you to unlock it DON't. Just close the password window.
Go to Start menu, Computer, Right click the drive, Chose to format the drive.
You will lose all the files on the drive but, you will get use of the drive back.
Hope it works for you.

I have a 2tb external Hitchi drive that is bitlocked. The drive will randomly re-lock itself and i cannot figure out why. I thought it may be a problem with the drive going into sleep mode so i got software that would prevent sleep mode but the drive still re-locks itself. The drive seems to most frequently re-lock and ask me for the password again after about 12hrs, but it has re-locked just seconds after unlocking it before. I have checked the drive with HDDScan and all the smart values look fine except for the CRC count because the drive has locked on me while transferring files, so i would obviously get a CRC error; the count is 4.

Does anyone know anything about this? How can i stop this drive from locking on me?

Any info would be great! Thanks!

Hi people,

This is my first post on this forum so please bear with me!

My question is:
I have a new notebook and I have used windows bit-locker to lock up the C drive. My notebook didn't come with a TPM chip so I used a work around to get it working by using a flash drive with the keys installed on it at the boot process.

However Ive installed VMware and its taken up a lot of space on drive C. what I want to do now is allocate some of the free space on the D: drive to the C drive, if that makes sense?

Just to clarify my D: drive has no bit-locker encryption on it, but my C: drive does.

Want I want to know is can i just use a partition tool to give the C drive some more space or will this cause problems as its using the bit-locker software?

Also if I can do this, whats the best partition tool to use?

Many thanks in advance,

My laptop suddenly crashed yesterday and when I restarted it, it says "windows failed to load because the system registry file is missing or corrupt" error 0xc000009 . I tried to do System Repair using Windows 7 CD but since 2 of my drives (not the C system drive but E & F drives that I had previously partitioned), it asked me for the bitlocker key. Unfortunately, I lost the flash drive I had my keys saved on. So I was thinking of fully re-uninstalling Windows if that is possible. But I want to make sure that the 2 drives E & F will be normally usable by unlocking those drives using the password since I have 2 years of my works there and I have no back up of those files. So, if I re-installed Windows, do I have to take the risk of having to format those 2 drives afterwards? I don't even know how I got this error in the first place. I hadn't messed with any files on the C drive at all.
Nervously waiting for help.

A:Reinstalling Windows7 on pc which isn't booting with Bitlocked drives

I know of no way to recover your files if you lose your Bitlocker key.

To try on the OS HD Troubleshooting Windows 7 Failure to Start or to do a Clean Reinstall you should unplug all other HD's anyway, so whether you later format them is a separate issue.

The lesson here is obviously to have a backup of both your files and your encryption key. BitLocker Drive Encryption - Unlock a Locked OS Drive

I have windows 7 pro, and I would like to bitlock my D:/ drive, however I have a windows backup image of my C:/ drive on that bitlocked D:/ drive, and if I have to do a system restore from image, would i run into problems during this if I use the windows 7 recovery tools disc, or would it ask me to enter the bitlock password for D:/ and then I can choose the image?
Thank you

A:Recovery image from bitlocked partition question

First of all,BitLocker is in Windows 7 Ultimate and Enterprise only.

As far as I know,you will enter the password and choose the recovery image.

You can also go to Recovery Options by typing F8 during booting and select Repair Your Computer. It's the same thing as in your DVD.
If you don't see it,after logging on,go to Start,All Programs,Accessories,right-click Command Prompt and select "Run as administrator". When prompted by UAC,click Yes.Type:
reagentc /enable

I hope you find my advice helpful.

A:Bitlocked External Hard Drive Crash


I'm afraid it doesn't look good, if the encrypted partition was gone, and you replaced it with a new partition, then it now well and truly gone.

Post a screen capture image of your disk management screen so we can have a quick look for you.

BitLocker is just a feature to encrypt the drive. However, if the user would like to format the drive,
BitLocker feature cannot prevent  the encrypted drive to be formatting(that is what happened with me). After formatting, the BitLocker feature will
also disappear since the formatted drive is a new drive.. anybody have any solution to this .. kindly help i want my data back.. thanks

Hope someone can help me.

I'm going through to search through all the threads pertaining to Bitlocker to see if anyone had a similar issue but no luck yet.


1) Windows 7 x64 was on C:
2) G: was Bitlocker encrypted

Got a new GPU and went through a bunch of stuff before determining that it was bad and needed to be RMA'd. One step included doing a fresh install of Windows 7.

After re-installation, drive G: just showed as being a "New Volume" that was completely empty when I viewed its contents.

Seems like something went funky after I reformatted so that the drive isn't being viewed as an encrypted drive (at least I hope that's the case).

Is it possible to re-associate the drive somehow so I can try to unlock it with my passphrase? I don't have one of those key files that you're asked to create when encrypting the drive. I do know the passphrase that was used to unlock it and didn't bother with the key file because I know I'd never forget the passphrase.

Possible to get my data back or am I hosed? Tried asking on the Microsoft Social TechNet forum but no help there after 100+ views.

Thanks for any help.

A:Bitlocked Drive Shows As Empty After Re-installing Windows 7?

Hello Shadow, and welcome to Seven Forums.

I hate to say this, but is sounds like you may have also formatted the G: drive as well since it now shows as a "New Volume" and no longer encrypted by BitLocker. If this was the case, then you are out of luck, and lost all data that was on the G: drive.

If you had only formatted the C: drive and reinstalled Windows on the C: drive, the G: drive would have still showed as being encrypted by BitLocker.

I sure hope that you had a backup or a system image backup of the G: drive.

Could you post a screenshot of your Disk Management (diskmgmt.msc) window showing all of youe HDD's layout to be certain if this may be the case?

Hi, since a couple of weeks, system update prompts me to update my NVMe disk firmware. It downloads and runs Lenovo Storage Device Firmware Update Utility, but it always fails with the same error: Update Failed: Firmware update FAILED! RC=0x1 Stopped by a device reason.  This happens to me with the last version of the firmware update toot (FWNV29), but also has happened to me with previous versions. Also, downloading FWNV29 and running it independently from system update leads to the same error. Can someone help? Thanks. The log from fwwinsd.exe (fwwinsd.log) shows the following:[2019/03/27 07:47:09]: CFWWinDlg::OnInitDialog - IN

Hello guys,

I am wondering if anyone can help me figure out what on earth is causing these strange freezes.

I have two external hard drives with these specs:
HGST HDS 5C4040ALE630 - 4 TB NTFS Partition - GPT
Hitachi HDS5C3020ALA632 - 2 TB NTFS Partition - MBR
(Both are encrypted with Bitlocker, might have something to do with it)

Both are hooked up via USB3.0 ports (with 3.0 cables) directly into the motherboard.

So what is the problem? Well I can access them both at the same time, no problem. I can copy and move files from one of the drives to my internal drives and vice versa, even at the same time. But, I can NOT copy or move files from one drive directly to the other. The transfer process will start but freeze after a few dozen megabytes and stay frozen until I cancel the transfer, and wait a few minutes for it to react.

I use TeraCopy, I have uninstalled and tried the normal windows 7 file transfer but that hasn't helped either. Furthermore, with windows 7's default file transfer I wasn't able to cancel it and I eventually had to shut down the pc.

So right now I have to move files from drive A to an internal drive C, then move the file from drive C to drive B. It is simply annoying and I do not understand what is happening.

I've also checked the drives, they have no errors, no bad sectors, they are running great (no noises either).

Any ideas? Thanks a lot in advance!

A:Moving files between two Bitlocked external harddrives closely freezes

Do any errors come up saying anything at all about bitlocker? Because i think you are probably right when you said that bitlocker could have something to do with it because what bitlocker does is encrypt to secure the files you want secured. So i would try turning that off first and then try and transfer the files you need/want and see if it succeeds. If it doesnt; post back.
