The OCZ Vetex 2E (180 GB) in my notebook just lost all of its data. I used the drive as system drive and had a Linux distro installed to it. All of a sudden, the system wouldn't find a bootable device. I thought that the boot sector was damaged, so I booted the system into a live Linux from a USB device and the drive showed up as "unpartitioned". I thought: "Oh damn, the partition table is damaged." However, as I grabbed a hex-view of the device, all that was stored on it was zeroes, as if an "ATA secure-erase" command had been issued to it. (But I was sure it had not.) I decided to replace the drive, since obviously the memory was becoming unreliable, but I thought I might operate it again until I get a new drive. So I performed a "secure-erase" (to make sure every page is in fact physically erased and in a clean state) and installed the operating system to it again. After installation, my system booted from the device just fine. So I thought: "Ok, it's probably gonna stay until the new drive arrives. After that I'm just gonna replace it just in case." However, the data only remained on the drive until I shut the system down. After power-cycling it, it came up completely blank (all sectors storing only zeroes) again. I heard that SSDs, especially from the Vertex 2E series, which appear to have quite its share of reliability issues, might either turn read-only or "panic-lock" and completely disappear from the host system (basically the controller "dying"), without any prior warnings, so I have quite recent backups of all important data on a conventional hard-disk drive. However, that the SSD would just become "volatile", losing its contents on power-down is "new" for me. What's also interesting is that all S.M.A.R.T. values look normal (or rather very good) and self-tests complete without any errors. The drive is 3 years old now, so it's out-of-warrenty etc. and "allowed to fail". However, that flash memory basically "continues working" but becomes "volatile" is something that I don't really grasp. Anyone has an idea what might have happened here?
