WDC74GB Raptor Quandry

I've got a wonderful pair of first-(okay, maybe second?) generation WD Raptors: the original 74GBs. They just passed their 5-year warranty mark and, although I'm not using them anymore, I gave them to a friend who needed an inexpensive rig put together and, after 5 years of wonderful service, on many and varied motherboards/RAID setups, one of them appears to have gone tits-up. But in a rather strange way.

The last board these HDDs were RAIDed on was an Intel DP45SG, and there they worked fine for about six months, until that rig was boxed up and put away. They sat, in their original anti-static bags (I am such an OCD-kinda guy!), in my closet for about a month, until last night, when my friend attached them to his newly-purchased EVGA 780i FTW. Where one (not both) of them was identified (by the 'board) as a WD800BB. In other words, it was seen as a completely different (and rather shitty) old HDD. I flashed the motherboard BIOS up to date (the Jan 2009 "SZ17" BIOS) from the June 2008 that it came with...no difference.

I'm going to attach the poor buggers to my current motherboard (DFI T2RSB) when I get home from work to double-check 'em, but I was wondering if I'd be able to (if I have to) flash the poor beastie back to a WDC74GB firmware.

Peace.
