This is my first post here at HDDGuru.

If this has been mentioned already, I apologize. I didn't
find any previous posts on the subject but I suppose I
might have missed something.

Anyway, I use HDDScan (great LLF tool). It has never
caused me to stop and say... "hey... which drive?" but
today that very thing happened.

I setup a new PC with identical drives - same model #
down to the last digit. I found myself in a position where
I had to do a LLF of one of the two drives so I installed
and launched HDDScan. As in the older version, the
program showed all the drives but didn't show the drive
letter associated with each drive. That left me scratching
my head wondering which of the two drives I should choose
for the LLF. Choosing one was correct but choosing the
other would wipe my boot drive and there was no way to
distinguish between the two drives... not even a drive #
reference (ie. drive 0, drive 1, drive 3, etc...).

So I had to open WinXP Administrative Tools Disk Mgmt
to see whether my boot drive (C:) was on drive 0 or 1
or something else. In my case it was on drive 4 and the
drive I wanted to wipe was shown as drive 3. So on
that very tenuous basis, I made a choice in HDDSCan.

I assumed that HDDScan was showing me the drives in
numerical order (ie. 3 listed ahead of/above 4) so I chose
to begin the LLF of the first drive in the list - that turned
out to be correct but it would have been much less
ambiguous if the software had shown a drive number and
maybe a drive letter where available.

So that's what I'd like to suggest. IMHO, HDDScan would
benefit from additional drive identification info - preferably
drive letter and/or drive number.... anything to help the
user distinguish between identical drives.

Im stuck in the same boat with two 750gig drives, far short of unplugging one I can't offer advice.

On XP LLF won't show me a drive serial number, but on Vista it will, but the program won't wipe a disk on Vista for me, so I use both OS's.
