I installed 320 Series SSDSA2CW300G310 in my ThinkPad X200 with Windows7 Professional.
I enjoyed it because the SSD was so fast!!
However, my PC suddenly rebooted and it doesn't recognize the SSD.
During rebooting, my PC shows the following error message after BIOS checks;
2110: HDD0 (Hard disk drive) read error
I didn't have any configuration change just before the trouble.
After the incident, I tried firmware update for the SSD with tool v1.92 and the tool recognized the SSD but update was failed.
(I don't use any security protection except Windows Logon Security.)
I also tried to connected the SSD with other OS and other PC, but it was failed to mount.
Your advice would be so helpful.
