I have a Kingston 128gb SSD which was running Windows 7 pro 64. I started having problems when the drive would just shut off while the computer was running. I tried putting it as a secondary drive in another computer both internally and as a SATA to USB and the drive would appear and then disappear ~5 min later. In the interim all of the data seems to be there and intact. I updated the firmware from the Kingston website on a separate computer and the disappearing problem went away, except now the drive is no longer recognized by the BIOS on my primary computer (but does work as a secondary drive on other computers). Is this as simple as updating my BIOS? Thanks for your time, I know it is probably a no brainer for most of you but obviously not for me.
