SSD Detected But Not Accessible

Sun Jun 23, 2019 11:31 pm

My father-in-law's SSD just up and stopped working recently. He said it was doing some updates one night as it was shutting down, and the next day nothing. After guiding him through some high level troubleshooting, I had him send me the drive so I could try to get some important data off. I've tried booting from the drive, plugging it in internally as a second drive, and putting it in a USB external hdd enclosure. Unfortunately, although it can be seen from the BIOS and Device Manager, I haven't been able to get into the drive. The only "success" I've had is internally connected as a secondary drive in that I'm able to see the drive letter come up, but it says it's not accessible, also visible in device manager.

I know that's pretty vague, but I'm not working with much here. If anyone has any ideas on how to get into this thing, I'm more than happy to provide any info I can.

I take it you did not make a backup of your disk before trying to mess with the partitions? That is the first thing to do, do not do anything on the disk with partitions, file system, etc.. without a backup if something fails.

My usual goto for that sort of thing is a Linux liveCD with gparted on it. That should at least tell you if the partition table is intact. You might be able to get that from within windows also though since it sounds like the OS can see the drive it just can't make any sense of it. I'd probably try looking for a way to do a byte for byte copy using the windows equivalent of dd(robocopy?). If you aren't able to create some kind of disk image that way, then I'd say chances of successfully retrieving anything from the drive are not good.
Do not meddle in the affairs of archers, for they are subtle and you won't hear them coming.

Was BitLocker enabled on the drive by any chance? If so, it's encrypted and you won't be getting into that without it being in the original PC.

BitLocker was something I hadn't thought of, but he's definitely the tin foil hat type that would enable it. I asked and he said he can't recall for sure, but doesn't remember specifically enabling it. Is there any way to check/know?

I'm not sure if it'll show without being in the original system. You can try looking at BitLocker Drive Encryption in the Control Panel.

I had a similar problem recently. My portable backup SSD (Samsung 260 Pro) suddenly became inaccessible and did not show up as a drive. I had been using it with one of those USB3 portable drive enclosures. For some reason, using a USB3 external docking station made the drive visibie to my OS (Win 7Pro) and it showed as having no partition. Since there was nothing to loose, I partitioned it and formatted it as NTFS and its working again. I'm still using the docking station as the backup point and just taking the bare drive (in an antistatic bag) home for security. My friend who helped me said to make sure The docking station powered up the drive properly (it has a light) before connecting the USB cable to the PC. And to demount drive, then disconnect USB cable, then power down docking station by way of not zorching the partition again.

As a guess I suppose that what originally happened before was that unplugging my external drive case caused a transient that wiped the partition table.

Unfortunately since I need to salvage data off this drive, reformatting it is out of the question.

I've had good luck with GetDataBack NTFS back in the day, no clue if it's still any good. It will discover all sorts of garbage you don't care about (since it just crawls the disk looking for NTFS data structures) but it's more than zero.

Brand and model of SSD? I had a Sandforce based SSD that started working fine after keeping it connected to my PC as a secondary drive and letting it idle for a few hours. I think the SSD controller figured out what was wrong and fixed whatever internal mess had been created due to whatever reason. You could try doing the same. Another idea is to see if the SSD has a newer firmware version and try updating it to the new version. Maybe that might revive it.

For me, most recently it was Recuva that saved the day, although admittedly, it was a UFD and not an SSD and the latter will likely have a more complicated internal layout for storing data.
