Re: HD Protect Passwords



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.
