I have a Samsung Portable SSD T5 1TB drive which has been partitioned under Windows 10. As of today, I can't access to the drive anymore, as the Samsung Portable SSD Software 1.6.6 tells me "Failed to check free space or failed to locate a volume".

I must say that:

  • Device Manager tells me that the Samsung Portable SSD T5 SCSI Disk is present
  • Disk Management tells me there are two partitions: a 200 MB partition (Disk 1, Partition 1) with no file system, and a 931.19 GB partition (Disk 2, Partition 2) with no file system. Both show "Healthy" as a status.

  • Does it show in Windows Explorer? If so, right-click on it, go to Properties > Tools > Check and let Windows inspect your drive. It may have to go offline after check, then be brought back online. Could be your drive is infected, too. I suppose you've tried it in a different USB port? What happens if you try to update the SSD driver in Device Manager? EDIT: there's an excellent tool by Samsung called Samsung Magician that could help you diagnose your SSD, update/upgrade its firmware, etc...

  • Diagnose with Samsung Magician wouldn't help it - the partion is healthy. The problem is with file system! Updating drivers/firmware may lead to complete data loss!

  • You might try reseating the SSD(s). Maybe they aren't getting the right ground or connection. Only do this if you have experienced, otherwise find a friend who knows about the internal parts of the machine. If you do have experience, cleaning up the CPU fan, etc., while you are there, this may help with other situations, heat, etc.

  • @Didier the drive doesn't show in Windows Explorer. Samsung Magician detects the Drive, but doesn't detect the file system unfortunately.

  • Does it propose a firmware upgrade/update for this SSD?

It looks like file system on SSD is corrupted.

You can try to recover the files with some of recovery tools, like R-Studio or Recuva. Attention: using tools you can make data unrecoverable.

If the data on SSD is really important, I’d contact the professional recovery service. To avoid such situation I highly advise to have periodically backups. For 1TB of data cloud storage can be an efficient solution (starting from 5USD/1TB monthly depending on provider).

  • What staff? If you know the better recovery solution - advise it! I used only Recuva and R-Studio. It helped in some cases. Regarding backups - I haven't mentioned any vendor, and I don't see any problems to recommend doing backups in 2020!

  • I don't see any problem either, unless you try to push a specific product or vendor. As for Recuva and other data-recovery software, they only work when you have actual access to the drive. Hence my questions: Is the drive visible in Explorer, and if so, check it with Windows's tool; Is the drive visible in Device Manager (seems so) and try to update its driver. As for Samsung Magician, I'm posting from a Lenovo laptop with a Samsung SSD in it, and I ugraded the firmware just a week ago. Guess what? No data loss. None. Zippo.

    You don't know, what are you talking about. The drive may be visible in Explorer, only if file system is recognized. From device manager - you can see, that file system is missing, so this question is useless. SSD or better to say controller driver doesn't affect the file system below, if it corrupt. Updating firmware shouldn't lead to data loss with healthy drive, but may limit the recoverabilty of currupted one.

  • Regarding visibility in Explorer to recover data - the drive shouldn't be visible to use R-Studio or for example Ontrack EasyRecovery or Recuva - ccleaner.com/docs/recuva/using-recuva/…

As it was written by batistuta09 You can try some of advanced data recovery software (UFS explorer, R-studio, Recuva). Probably You will get some rsults. You asked about ONTRACK, Yes, they are reputable company in data recovery area.

I had similar problem with Samsung Portable SSD T5 2TB when I tried Migrate OS to SSD using Diskgenius Free Software. Same "Failed to check free space or failed to locate a volume". I resolved it with registry cure software (I have Avast Cleanup Premium), but you can try other similar software. Problem was with chkdsk check, and it's long time checking and resolving ( depends on your hardware, but it should be 1 hour or more). That solves problem with access to the drive, but it wasn't bootable drive and it didn't work for me as "Migration OS to SSD". To avoid this problem of migrating data from HDD to SSD, try to use Samsung Data Migration software , if you are using Samsung SSD products.
