I'm looking into a WD400BB, which is behaving quite oddly. It is recognised by BIOS, MHDD (I've run an F4 scan on the first 5GB, no problems) and Linux.
It has problems getting recognised during BIOS boot, unless it's on its own IDE channel as single master. I had to boot from CD, since when I tried to put a WD120GB in 1st IDE channel the PC locks up.
Strange characters in identification string
^WD^C ^WD400B^B-00^DE^A0 (Note: in MHDD these appear as funny high-ASCII chars)
Data read seems to be partially garbled.
E.g. output of hdparm (Linux):

I've mirrored the first few GBytes, but data seems partially garbled. Strings from drive image reveal data suspiciosly like garbled text, e.g.:
