Hi Gregg,
Actually it's not my drive. I was just replying to the person who had
the problem. I am by no means a hardware expert, but I thought
information on a hard drive was stored in a section called the master
boot record, rather than "the HD's CMOS" (which, BTW, stands for
Complementary Metal Oxide Semiconductor - a reference to the
manufacturing process rather than its function, and is probably more
properly called von-volatile RAM). If it is truly stored in in an NVRAM
chip, you could remove it simply by removing power to the chip for a
while. However, I think what you need to do is remove data that is
written onto the drive itself. That's why I made the fdisk /mbr
suggestion: to try to clear the password from the master boot record. I
still think it's worth a try.
