funny, it looks like I was able to enter a 35-character password via the Lenovo Bios (it did not allow 36). This has worked for months and months with no problem, and still works for the drive that is functional.
the RST allows only 32 characters for the ata pwd, which is according to specification.
I have no idea if this has anything to do with it - I would suppose not, since the other drive works fine with such a long password.
Did you ever find a solution to your problem? or perhaps contacted customer support?
I am in a very similar situation, i experienced a BSOD in windows 7 on my laptop (thinkpad t410). and now it just stalls after i input the correct password (that i have been using daily for the last year).
I also have the same symptom, that i can not enter BIOS when the SSD is plugged in.
The same problem with Lenovo Thinkpad x201 and intel ssd 320. Guys have you solve it?
