Today my system froze and failed to reboot. I plugged in an Ubuntu live USB stick and booted from it. Then I discovered the problem that my Intel SSD 320 broke. The output of hdparm is attached to the end of the blog post. You can see that the device size is reduced to 8 MB from 120 GB and the serial number is called BAD_CTX 00000159. The firmware of the SSD was up-to-date and the last firmware update should have fixed the 8 MB bug.
The Intel SSD 320 is my second SSD. My first SSD was a Super Talent Ultradrive GX 64GB, which died after around fifteen month of heavy use. It left a big bunch of my data corruption behind. SSDs seems to be very unreliable. Both SSDs died, but I cant remember that one of my HDDs died.
