I found some similar threads (such as this one) but none with an actual diagnosis and resolution.
I have a Thinkpad T520 with a 1TB Samsung 840 EVO (an SSD like all the other reports of this problem). It has worked fine for a month then suddenly I am seeing this error on boot.
I have the latest BIOS and drive firmware updates as of the time of this writing.
The error appears to be "bogus" in that booting from a Linux CD, and from a Windows Recovery CD, the drive is seen just fine, with no errors reported, despite the "detection error" reported by the BIOS.
SMART status as reported by Linux shows the drive to be in excellent condition with no error or warning flags:

The drive also works fine in other machines, Windows and Linux, even when it is the boot device. Other SSDs placed in this machine also show the same error now (tried a 256GB Samsung 840 EVO and a 512GB Crucial m4). It is most certainly an issue with the machine, and only seems to affect the BIOS, during boot (the fact that the OS can still see the drive means it was at minimum powered and initialized at some point).
Removing and reinserting the drive doesn't help.
Removing the DVD drive doesn't help.
Power cycling (even unplugging and removing the battery for a while) doesn't help.
I noticed that just prior to this event the computer was being extremely slow (although no IO errors were being reported) and then hung on a Windows shutdown, after which I had to force a power off (after about 15 minutes of waiting, with no drive activity). On the next boot, the problem began.
It is clearly an issue with the BIOS, and not an uncommon problem. When will the fix be available?
