Windows 7: SSD stopped working properly

Actually, although cloning is a valuable tool for replicating a drive (such as when replacing a drive with a newer or larger one), I don't recommend cloning for backups. It takes too long and, if cloning to an SSD, wastes part of the finite write life.

First, I recommend keeping system files (OS and programs) segregated from data files. An example is putting the System files on an SSD and data on an HDD. For computers that have only one drive, the OS and programs would go on one partition and the data on a separate partition.

To backup and restore System files, imaging is the most efficient. Computer imaging is like film photography. When one takes a picture with an old style film camera, the picture taken is first made into a negative. The negative is then used to make a print (the actual picture). An image is the equivalent of a photographic negative and is used to recreate the original drive or partition.

I recommend Macrium Reflect Free for imaging (it can also be used for cloning). One reason imaging is better than cloning is one can keep multiple images on the same backup drive, such as images taken at different points in time, something you can't do with cloning.

To restore an image to a drive or partition, one needs to have some kind of rescue media. The most popular media to use is either a CD or a dedicated USB flash drive. Macrium Reflect has a provision for making a rescue CD or USB flash drive. To restore a drive, just boot into the rescue disk or flash drive, select the image you want to restore from, then let the computer do its thing.

While one can use cloning or imaging for backing up data, it is far too cumbersome and will take too long and take up too much space. For backing up data, I recommend a folder/file syncing program, such as FreeFileSync. Folder/file syncing programs, when set to Mirror (not the same as RAID 1 mirroring) for making a backup, work by comparing a folder (they consider a drive to be a folder) with the same folder on the backup drive, then copying new and changed files from the source folder (or, in the case, the entire drive or partition) to the destination folder (drive) and deleting older, duplicate files as needed to create what is essentially a clone of the source folder (drive). Since only files that have changed or been added or deleted are involved in the process, updating the backup is much faster and far more efficient than actual cloning, which involves everything on the drive every time.

Using a folder/file syncing for the first time can be daunting but after you have set up the necessary profiles, it takes only a couple, three quick mouse clicks to get the ball rolling every time you update your backup (which should be frequently). If you decide to use FreeFileSync and can't figure out how to set it up (I couldn't when I first got it), let us know and one of us can walk you through it (once you understand how it works, it's actually quite easy).

Quick update - I can 100% definitely see all my files and folders which is great! They are all still there. I need help figuring out how to recover them though. Because I am working in Linux rather than Windows, I can't change directory to point to the recovery folder on my new SSD. Do I need to type a command to mount the drive/partition?

EDIT - Nevermind, I figured the command out to mount the drive. Copied the files across to the new SSD and booted back into Windows.........SUCCESS!!! Data recovered and tested working!! Thanks very much everyone who has helped especially Jumanji, everyone's input has been helpful to resolve what looks to be a severely corrupted drive!

Now for the bonus part - Trying to get my old SSD wiped clean and working again from fresh. Suggestions?

Lady Fitzgerald - Thanks for your post on cloning/imaging. My plan is to move my Windows OS to my new SSD drive and move my data and applications that I have just recovered onto the mechanical HDD so I will definitely be trying out Macrium reflect for this.

Congrats on your successful recovery. The whole credit goes to your ability to innovate and execute. Anyone elses's role including mine is just supplementary.( I am mentioning your using TestDisk from SystemRescueCD and catching up from thereon.) Your successful recovery will no doubt be helpful for others who may find themselves in a similar situation. To complete it,you may post the Linux command you used to mount the external destination drive so that they need not go searching for it.( Me too knows nil on Linux )

Thanks Jumanji!

Yes good point, for anyone reading this who suffers a similar problem and has to use a Linux based rescue system you need to do the following.

Boot into the graphical OS using the CD/USB
Launch gparted or similar tool.
Note the location of the drive you wish to restore to. This will be displayed in the drives list top right on Gparted. It is likely dev/sda or dev/sdb. Close gparted once noted.
Launch a filesystem browser
Browse to 'Root' and then 'media'. Open 'media' folder.
Right click and create directory 'Recovery_disk' and then close filesystem browser
open terminal command prompt. Type the following command-

mount -t ntfs-3g /dev/sdb1 (or where ever the drive you noted earlier is located) /media/Recovery_disk

Hit enter

The folder name needs to be typed exactly including uppercase and lower case letters. Assuming no error messages are returned, the drive will now be mounted in the media\Recovery_disk folder. You can check this by using the filesystem browser, browse to the folder and check its capacity matches the size of the disk you are trying to recover too.

Run testdisk as normal and when copying files from your damaged drive, choose the media\Recovery_disk folder as the destination. Copy should complete and you can now boot back into Windows and see your files.

On a separate note Jumanji, do you have any ideas how I can try to recover my corrupted SSD to wipe it clean and start again? Rebuild MBR??

That was a good and elaborate procedure and writeup (your post# 34). Thanks.

And yes, as a first measure check whether sector 0 takes the MBR.( I have my doubt whether Sector 0 is good or gone bad) Use TestDisk to write the MBR code. You can try it both in Windows as well as Linux.(Please remove all external drives so that you do not do this action on those accidenatally. Also take care that you don't do that on your system drive)

If MBR could not be written, then your disk has gone bad and is irreparable.

Other steps:

In Linux TestDisk, select your 120GB disk, [Advanced]. When [Boot] is highlighted press enter. That will take you to the screen showing the status of the Boot Sector at sector 2048 and the backup bootsector.( remember Partition Recovery Wizard did not find the boot sector at 2048. It showed the start sector as Sector 0)

If boot sector is bad and backup bootsector is OK, then highlight [Backup BS] and press enter to write the backup to sector 2048.

If both are bad, then [Rebuild BS] and press Enter. This will rebuild the missing/corrupted boot sector at 2048.

If both boot sectors are OK, then [Repair MFT] Enter.. In most cases TestDisk will fail to repair MFT. That is when the author of TestDisk himself recommends third party commercial sotware like Getdataback.

I am not giving elaborate instructions since you have by now become a master in using TestDisk..

Final Update - SSD looks dead and cant be saved. I think there is a physical failure with the drive. In Linux I used test disk to check the boot section. It reported boot ok but back up boot bad. I rebuilt MBR, still no good and in Windows its still seen as a bad disk by PW. Disk manager sees everything as all good which it has all along.

Again in Linux I tried Gparted to format the drive which it appears to have done successfully. Test disks shows the partition as new clean and empty but in Windows it still recognises it as a bad disk so it looks a write off in terms of recovery the disk itself. Nothing else I can try I don't think.

At least I got the data though!
