Adata 256GB SSD died, **I fixed it**, now I can't recover data from it

I have an Adata 256GB SSD that just died all of a sudden, PC would not see it in BIOS, and plugging it in externally to other PC's would not do anything, it wouldn't even show up in disk management. I ended up taking it apart and reflowing it, and surprisingly, It Worked!

Now it shows up in disk management as unallocated, and my GetData Recover My Files software could see and scan it. Unfortunately, it could not find any files on it (I have always used this software for data recovery and have had a fairly high success rate with it).

Does anyone have any suggestions for software to recover data from a functioning (I guess) SSD? I appreciate any help. Thanks!

Don’t bother trying it yourself, in fact don’t even power it on.

Due to the nature of the SSD, it is almost impossible to do meaningful data recovery especially if you turned it on again. The data may be garbage-collected, the FTL information may be lost, so even if most of the data is still there, it is as good as junk.

Send it to professional data recovery shops if you care about the data.

It will be expensive and still might not get much back ;-{

Most professional data recovery software has a demo version, such as:

Active @ Boot Disk

https://www.boot-disk.com/index.html

  • What it will do is show you if recovery is feasible. *

If it is just corruption of the partition table or the like recovery is most likely possible.

Or TestDisk v7.2 which is a bit “techie” but it is free and full featured.

@aactech - Armen had tried using a data recovery app, I doubt this will be any better. Unlike HDD's SSD's don't have a mechanical state that's recoverable from.

Hi Dan,

Yes I understand the difference between HDD and SSD. I do data recovery.

In my experience, most data "loss" is due to corruption of the partition table - I would estimate 90% of the time. To truly loose the data the entire drive would have to be overwritten repeatedly a number of times.

Armen had one of those 10% experiences where it was hardware and he brilliantly overcame that. If the "reflowing" destoyed the data well then that is it but there is still a chance.

"GetData Recover My Files" is kind of basic and is kind of weak for partitiion recovery, as a lot of the so called data recovery programs are. Programs like "Active @ Boot Disk" work at a much deeper level.

This is a big topic with many different views depending on people's experience.

@aactech SSD's don't has a partition table like a HDD. the onboard controller keeps a record of the assigned blocks per the given file. Once the table is blown away that the end of it!

@danj

But then where is the partition table? They still have either Master Boot Record (MBR) or GUID Partition Table (GPT). And then why was I able to recover an mSATA drive recently by fixing the the partion table? I am very interested in this question.

@aactech - here's a good write up which should help explain things How Do SSDs Work?

To clarify, I didn't say it didn't have a partition table its how the information is stored within the drive.

A HDD used magnetic regions on a platter so its state is stored mechanically. SSD's work on block level within the flash as a table access by the SSD controller.

mSATA SSD or a AHCI/PCIe or NVMe/PCIe SSD all use similar controllers on the flash side. Here's a bit more on that Testing SATA Express and Why We Need Faster SSD's

Go to: TheTechMentor.com search for how to recover a crashed hard drive (any hard drive). I have used these methods and the various software many times with great success. It also gives you the tools and knowledge to help your family and friends that have the same problem. Make sure and do not write anything to the drive your trying to recover data from or you will over write the data you are trying to recover. Before you start handling your PC components you might want to invest in an anti static wrist strap and or anti static mat. You don't want to make things any worse. I have always been able to recover most if not all the data using these methods. Then see TheTechMentor.com/post/35 portable applications every tech needs do yourself a favor and install monitoring software on your computer that will e-mail your phone whenever anything is starting to go wrong with your system. FINALLY GET CLONING SOFTWARE and clone your hard drive to an external hard drive every other month. You can delete the old clones. If something ever goes wrong transfer the latest clone from the external drive to a new hard drive which will be hot swappable with the one in your computer and contain your operating system, partitions, and all your files. You won't even have to change anything in your bios to recognize it.

You missed the point! This is a hardware level issue not a software level problem.
