Crucial SSD Went RAW in the file system

MrMatt said:

Greetings, hope your day is going well...

I followed your directions, and showed both the list and boot page..
Does not look good.
Just to note, this is a hard drive I got off of amazon, i could return it.. ( I think), and get a replacement if this becomes too much of a burden or an unlikely solve issue.... just saying...

Pelase see below...

Boy! You have done it on a wrong partition: 1 P MS Reserved Start sector 34 end sector 32767 Size 32734 sectors
( Microsoft reserved partition ). This partition does not have a file system. This 16MB space is kept reserved by Microsoft for operating system use. User cannot see it in Disk Management and cannot access it. Kept hidden.

Please pay attention and do it on the second partition which is your data partition: 2 P MS Data Start Sector 32768 End sector 976771071 Size 976738304 sectors (Basic data partition). This has the NTFS file system and this is where your data is. We are checking the filesystem of this partition. I have shown this in the first and second screenshots in post #20

Please repeat the procedure on this partition and post the screenshot showing the status of the boot sectors.

If you do not want to try data recovery, you may return the SSD to Amazon. It is your prerogative. Check Your Account > Your Orders on Amazon. Return Window closure normally is one month from the date of purchase.

omgg... After reading all this I'm so glad I got the Pro Ultimate. (Back then it was much cheaper but I'm good for a lifetime.) This will take care of any PMS issues.

................. I am leaving tonight to go camping over the weekend, so will return Monday eve. to see your response..........

No problem. Enjoy your camping trip. You may see this post after your return and act upon it.. If you make any mistake you may have to repeat again

Remember to select the second MS Data partition

Fine. You did it right in your last post.
Running TestDisk so many times, you are already an expert in it.

To recoup what is already done:

Screen 5 gave you only two options. [Type] and [Image Creation], No option to check [Boot] or [List] folders/files.

We went into [Type]. In the next Screen 6 confirmed it is an MS Data partition and in the next Screen 7 which showed the partition type (File System) as Unknown ( and that is the problem) was redefined as NTFS.

In the next Screen 8 you got the option to check [Boot]. You did it and the next Screen 9 showed both Boot sector and backup boot sector are bad. { [List] did not show your folders/files but gave a message " Can't open file system.Filesystem seems damaged".}

You will repeat the same steps again till you reach the Screen that says "Boot sector bad. Backup boot sector bad" and continue to the next step from there.


Note:
If you remember what I had written here External drive data Lost - Windows 10

{Various possibilities exist:

1. ............

2. Boot sector - Bad
Backup boot sector - Bad
Execute [Rebuild BS] command ( Rebuilds the Volume Boot Record and writes it into the Partition start sector and partition end sector)

3. ...............

The above three operations should repair the boot sectors and make your drive accessible. A reboot is required.}

OK , The screen you see below, was your last screen that proclaims both Boot sector and backup boot sector bad.
Screen 9:


In the above screen highlight [Rebuild BS] and press Enter BS stands for Boot Sector



Screen 10:
In this screen [List] is highlighted. Press Enter


Screen 11:
In this Screen do you see all your folders/files? If yes, Press 'Q' to go to the previous screen.



Screen 12:
Highlight [Write] and press Enter.



Screen 13:
Confirm pressing 'Y' key. TestDisk will take the data from the Partition table in Sector 2 and write the extrapolated Partition Boot Record onto the start and end sectors of the partition.



Screen 14:
Do you now see the message that the Boot sector and Backup Boot Sector OK?. We shall do an extra check to ascertain the status of MFT ( Master File Table). Highlight [Repair MFT] and press Enter



Screen 15:
If you see the message that "MFT and MFT Mirror match perfectly" press Enter



Screen 16:
You will be returned to the Boot sector OK Backup boot sector OK screen. Close TestDisk by hitting on 'X' in the top Title bar, say a prayer and Reboot your PC



Can you access your SSD now? Post a screenshot of Windows Disk Management for all to see.

Note: All screenshots in this post taken in realtime on my SAMSUNG SSD 860 EVO 500GB Trial disk in which I replicated your SSD condition by removing the NTFS flag in the partition start sector 32768 and Partition end sector 976771071 that holds the the Patition Boot Record and its backup respectively ( using bootice), making the disk RAW and inaccessible.. Went through Screen 1 to screen 12, successfully restoring the disk and making it accessible again.

FANTASTIC! It worked!!!
No RAW file systems!!!!!!!!!
All folders saved and checked...........

You did a good job .....this time

MrMatt said:

....This is a newly installed drive, is there something I could have done duirng its installation which caused this corruption? I have installed both SSD's and HD's in the past, never had this issue...........

When you receive a new SSD or HDD you only format it. There is nothing you can do during installation to prevent the disk getting corrupted anytime later..

MrMatt said:

.........Can this drive be trusted?.. or does a corrupted drive have a tendency to repeat its corrupted behavior? Initally it seemed to work fine, I could see my folders, etc... then it went to the dark side.........

A good question. Hmmmm............. I trusted your disk because you said it is a new SSD and that a Crucial. If it was an old disk, I would have asked the OP to check its health using Crystal DiskInfo / Hard Disk Sentinel and post a screenshot before proceeding further. But now you have to do it and must for your own peace of mind..

MrMatt said:

......IF it becomes corrupted again, what would be your suggestion, ... just to repeat the above Test Disk procedures?

No and No. A disk may become RAW and inaccessible for many causative factors, known and unknown. For example if it is only a partition table corruption, simply running the Partition Recovery Wizard in MiniTool Partition Wizard or TestDisk ( different procedure) can repair and restore the partitions, When it comes to data recovery there is no "one size fits all". Always ask for expert help. Many a time the OPs try to do something or other on their own and make the disk worse before seeking expert help. That doesn't help the expert
.
To check the health of your SSD:

Crystal Disk Info: CrystalDiskInfo download | SourceForge.net Also CrystalDiskInfo - Crystal Dew World [en]

Sample screenshot:



HardDisk Sentinel: Trial version of Hard Disk Sentinel Hard Disk Sentinel Trial version - HDD health and temperature monitoring

Sample screenshot:



Since you have a Crucial SSD download and install Crucial Storage Executive Crucial Storage Executive Tool | Firmware Download | Crucial IN

Sample screenshot:



You may check the health, update the firmware and run Device Selftest ( This application takes quite a time to load when clicked. So wait patiently to give that time)

About your system disk PNY SSD CS900 240GB:
If the Operating system finds any minor problem with the filesystem, it may ask you to run checkdisk.
You only have 2% free space on it.. On a System disk for Checkdisk to run smoothly atleast 10% free space is recommended. Consider increasing the free space. https://support.microsoft.com/en-us/...8-831022bc9b32. (On a Data disk atleast 5% free space is recommended.)

OK. on your behalf I will be requesting the admins/mods to mark this thread solved.

Have a good day.

Have seen many people crying over a dead drive.
As any computer device, one day the drive will fail.
The only way to guaranty you don't loose your data is having a backup.
