120GB WD drive changes model number from 1200BB to 1210CB

What would cause a PATA IDE 120GB drive to change its model name from WD1200BB-22FTA to WD1210CB-23-23FUA1 !!! (exclamation marks given as part of the name)? Also the maximum 48-bit LBA for the drive went from 234,441,648 to 72,058,693,783,997,360, and Paragon backup reported the drive’s capacity at around 600GB. This happened with the drive connected to the motherboard’s built-in PATA controller (Intel G-41 chipset) or a Silicon Image SiL680A PCI controller card.

Try contacting WD directly for this dude

I have a feeling I’d have to pay WD for tech support because this 120GB desktop HD is way, way out of warranty and was being used only as a backup for an old system still running Windows 98SE (special old hardware attached, just won’t run on 2000 or XP), which doesn’t like anything over 137GB. It’s now backed up to a 1TB WD, and I can’t reproduce the problem. FZabkar noticed the pattern of bad bits and suggested it was related to pin #4 on the IDE cable. He’s probably right.
