I just bought my first SSD an hour ago, thought it was first hand, but I saw the box was open and there were files inside the SSD when I plugged it in to move my files over to the new drive.

Turns out, I did a couple of tests, SMART reports the disk is healthy. I created a new partition, unplugged, replugged it, and voila, the disk didn't show up. Went to gparted on linux to find I had no partition table. Created an msdos partition table and a fat32 partition, unplugged and replugged, and they were gone. Tested that about 3 times, no luck. I also tried with a gpt partition table, but I wasn't lucky either.

I may be doing something wrong, but if I'm doing so, I gotta relearn how disks work. Thank you very much.

  • You did “remote safely”, right?

  • @Daniel B I unmounted the drive, yes. Even if I hadn't there is no reason why a partition table would disappear. Jul 29, 2016 at 16:27
  • Unmounting is not necessarily enough. Please try again with turning off the PC completely.

  • I did turn off the PC completely to try install Ubuntu, and the installer did hold. But that doesn't mean anything, I copied the data using dd which copies it raw Jul 29, 2016 at 16:30
  • Your drive may be faulty. If files that the SSD had prior to you formatting it were not "preloaded software" installers, you may have recieved a used SSD. Try running tests. Also try another cable and another motherboard SATA port.

SATA cable or port may be faulty.

Try using another cable and plugging into a different motherboard SATA port.

I know the answer has already been selected, but I think it's worth adding that for similar issues, with partition tables getting corrupted and/or SSDs not being detected, the problem could also be trying to use SATA configured in "IDE mode" in the BIOS. When using SSDs, SATA should be set to "AHCI mode" (or "Combined Mode", but that's more complicated and I haven't investigated it; reportedly it only sets some of the available ports to AHCI).
