Windows XP and hard drive letter discrepancy

B

Bruce Hight

I hope someone can tell me what's going on here and what, if anything, I
should do about it.

The problem: My hard drive letter assignments don't make sense in re Windows
XP. (This probably stems from a crash I had last summer; a repair shop got
my machine up and running again, but couldn't explain just how. More on that
in a minute)

Here's what I mean:

I have two hard drives, one PATA, one SATA. Both are Seagates and (so far as
I know) have given me no trouble. Here is how they are now set up, at least
when I use them on a daily basis:

SATA drive (four partitions, 160 gigs):

C: -- Boot drive, with Windows XP Home (SP2), and my various programs.
L: -- Nothing much.
M: -- Nothing much.
N: -- Nothing much; some backup files.

PATA (two partitions, 60 gigs):
D: My Documents (Yes, I've got it on a separate hard drive from XP.)
O: This is weird: It used to be my C partition before last year's crash, and
XP
and program files are still there. I've left it alone.

Now, here's the weird part: When I try to run the repair option on the
Windows Recovery Console, it comes up offering me a D prompt! As in, D:\

Why would it do that? C: is the drive I boot from, according to Windows. O
has the old Windows
stuff. But WRC sees only D:.

Now: Last summer, before the crash and "professional" repair: What is now
the O drive was the C drive; I booted from it. I used the SATA drive for
some backup and had intended eventually to switch over to it for my boot
drive. But when I got it back from the repair guy, I found things changed to
their current state, and the repair guy couldn't explain how he ended up
with Windows
installed on the SATA drive and had it made the C: drive. (And he apparently
found a pretty old restore point, because it wasn't as up to date as the
version that had crashed.)

You're probably confused as all get out by now, and I know I am. At the time
of the repair, I was so happy to get most of my stuff back I didn't worry
much about the odd arrangement of drive letters, etc. But this unfinished
business bothers me, and I'm concerned that
if I had another problem, it might be impossible to run WRC thanks to this
weird business of coming up on the D drive.

Here's some more weirdness (to me, anyway):

In Windows XP, Computer Management/Disc Management lists the PATA drive (D/O
partitions) as Disc 0 and lists both partitions. It lists the SATA drive
(C/L/M/N partitions) as Disc 1 and all four partitions. It seems to be the
same in the Bios settings, because if I include Disc 0 in the boot-up
routine, my computer will boot up into Windows. But if I don't, if I just
list Disc 1, it will not. YET -- CM/DM clearly labels the C drive as the
Boot drive. It labels the D drive as the System drive. And it says that all
partitions are "healthy."

What's the difference between a boot drive and a systerm drive?

Maybe the only thing to do is a complete reinstall of just everything, but I
sure hate to do that if I can avoid it -- and fearful, because I'm not sure
what I might accidentally kill.

Any suggestions? Is there some test or repair command I should try, or just
leave well enough alone?

And if you're still reading this, thanks for your patience.

XP doesnt always configure SATA hds all that well unless its set up in RAID
with pressing the F6 option before recovery.However,in recovery type:DiskPart
In DiskPart all should be listed,if not,try installing the SATA controller
drivers
before recovery...
