Hard Drive as slave keeps system from booting

there's no form of windows corruption i ever hard of that will stop a system
from booting when the windows installation is on the slave, and the master
is the boot drive. is the drive spinning? i've seen wd diag programs give
good results on a shorted out drive one time, and then fail to access the
drive the next five times.

virus? reinstall the driver. but this seems unlikely, if, after
disconnecting it (as slave) the system will boot, then fail to boot after
reconnecting it as slave.

fix the mbr, what the hell, what have you got to lose. btw, this is a
symptom of a shorted out component - but the boot to the xp splash screen
doesn't fit that scenario and you diag of where it stops doesn't fit that
scenario.

download knoppix linux, make the cd, and see if the system will boot off the
knoppix cd, then try accessing the drive. if you can access it , you can
get the data. then try copy over that amdagp driver you mentioned with a
working version and try it out. no joy, then wipe the whole thing and
reinstall.

also, describe in more detail what happens when you boot with that drive as
a slave- you're not trying to boot from it, right?

good luck. this sounds like a true PITA.

I should've mentioned this before, but before I shut it down prior to
it not booting, I had experienced low memory warnings, which prompted
me to close everything out and reboot. Any thoughts on what might've
happened? I tested the memory and the MS Memory Diagnostics disk said
it's fine.

I suspect I'd have the same problem trying to slave this to a new
drive in the same system, as trying to slave it on another system. But
as a last resort I'll try it.

It's not a WD. I tried it as both Cable Select and Master Slave, and
also, I put the second drive (slave) from the dead system in the other
system and it booted fine. So it is tied to this drive.
I was wondering what was next in the boot sequence, too. Didn't know
if the driver it shows is the problem, or the next one. But also, the
other system where it won't boot as a slave, is not an AMD system?!
Why would it be trying to load AMD drivers? Where does the command to
load the drivers come from?
I found the following supposed boot sequence on the web:
"Ntldr reads the registry files, selects a hardware profile,
control set and loads device drivers, in that order.
Then, Ntoskrnl.exe takes over and starts Winlogon.exe which starts
Lsass.exe (Local Security Administration), this is the program
that displays the Welcome screen (If Professional Edition-the
Windows Log On dialog box), and allows the user to log on
with his/her user name and password."
If it's accurate, could I be getting to the WinXP splash screen if all
the drivers didn't load properly? I only see the drivers loading, and
stopping, when I try to boot to Safe Mode. Is the sequence, and
drivers, different for Safe Mode? Or could it be moving on to the
splash screen eventhough the drivers are still loading in the
background?
Also, the second, working system, when the drive is slaved to it,
halts when trying to get to Safe Mode at the entry following
amdagp.sys, which is agpCPQ.sys. And, fwiw, the first time that I did
it, I thought I saw a quick flash at amdagp.sys to hit (ESC?) to skip
the file, but then it continued on and halted at the next entry. And I
no longer see a prompt.
Searching my registry in the working system found entries for these
files at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\amdagp
Display Name REG_SZ AMD AGP Bus Filter Driver
ImagePath REG_EXPAND_SZ System32\Drivers\amdagp.sys
And for agpcpq.sys,
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\agpCPQ
but entitled Compaq AGP Bus Filter.
They're also both in ControlSet001 and ControlSet003.

Do I dare delete these values/entries? Of course, I still couldn't do
it on the problem machine. But how are these tied to a slave drive?!

However, something interesting I just found in a thread at a forum.
The gist of it was dealing with hangs at mup.sys, but one guy got past
that, and the next one was agp.sys, where it still hung. But that
thread had a few different fixes, apparently because of a few
different causes. If anyone's interested, and think they could help
use the info to figure it out, it's at:

Yes, it's NTFS. I'll try that, though see below re: enclosure, which

I got one, and the slave from the dead system got recognized right
away in my working system, with drive letters showing up in My
Computer.
When I hooked up the "dead" drive (which I actually did first), there
was a pop-up in the SysTray indicating a new device, and it did show
it as WD 6GB, but no drives showed up in My Computer, and the system
slowed to a MAJOR crawl. Couldn't get Task Manager up and had to
ultimately re-boot. Tried a few times, with the same, except nothing
in the SysTray after the initial hookup.

Any more thoughts? Help!

Try something better than the MS Memory Diagnostics-
Memtest86 or Memtest86+ (Google for them) ran for several
hours.

There is insufficient evidence to draw a conclusion but I
suspect you're infeced with some sort of virus, malware,
spyware or similar, which initially caused the problem and
is now crashing windows regardless of whether that was the
code's "original", intended purpose. If you have antivirus
boot disks and can scan the drive(s) you might try that.

Well now I wonder if it's coincidence that this is occurring
alongside the windows out-of-memory messages, as these two
quite different symptoms are not usually by a (single)
common cause.

When slaving the drive be clear on the jumper settings for
that drive AND the other, existing master. Other than that
it would seem likely to have a hang in current system if it
caused this in the other. This type of problem should be
caught by the drive manufacturer's diagnostics, did you
(re)run that?

It might not be that driver OR a next one, could be
something else windows it doing afterwards. Try going to
the repair console and running command;
C:\> chkdsk C: /R

Since the system previously worked and you hadn't JUST
finished installing a new driver, I doubt the solution is
deleting any of those files... That should be how it was
the last time it'd booted successfully so there is something
more at play here. Moving the drive to the other system
should indicate that the drive is the problem, unless of
course these two boxes were networked and a virus had spread
to the 2nd system, it was merely that the 2nd system hadn't
been rebooted yet when you did so to try this hard drive in
it... just throwing ideas out there, grab whatever applies.

If the drive still checks out ok with the manufacturer's
diagnostics I'd see about copying off data somehow (maybe
the USB enclosure idea I mentioned previously) or as master
alone on the secondardy ide channel. You could try a repair
install again or just use another HDD. If the prior
suggestions don't let you access the drive then I hope you
made backups of anything important.

Guess it's possible. I've now put a new drive and re-installed XP on
my "dead" system, loaded AVG on and in doing so, created rescue boot
discs with AVG. I'll swap out the new drive with the bad one and try
the discs. I so often come across errors when doing stuff that
requires me to either shut off my pop-up blocker/firewall/anti-virus
to allow what i'm trying to do to work, that I may have and forgotten
to re-enable it. But I've had Kaspersky active non-stop on the other
machine, that is indeed networked, and don't recall any hits on it.
Though that may not necessarily have happened, I guess.

I wasn't sure if, when running out-of-memory, it caused errors on the
hard drive, such as corrupted drivers. I don't know how out-of-memory
issues manifest in the system.

Yeah, I ran the WD Diagnostic Tool, as well as one that's on the
Ultimate Boot Disk, TestDisk, if you're familiar with that. Both say
they didn't find any errors. The author of TestDisk said to save the
log of the test, though, and email it to him. Unfortunately, it was
saved to the drive that I can't access.

No can do; Recovery Console stops at "examining 588000 or whatever MB
of disk (0) on ... I've now found that that only splashes for a
second prior to the Recovery Console starting. Nevertheless, the
console never starts to the point where I can do anything in it.

Except that the second system only has problems booting while the bad
drive is slaved to it; take it off and it's fine. So don't think it
would be a virus.

Sorry, my last post was so long that the part where I mentioned the
enclosure must've gotten snipped.
I got one, and the slave from the dead system got recognized right
away in my working system, with drive letters showing up in My
Computer.
When I hooked up the "dead" drive (which I actually did first), there
was a pop-up in the SysTray indicating a new device, and it did show
it as WD 6GB, but no drives showed up in My Computer, and the system
slowed to a MAJOR crawl. Couldn't get Task Manager up and had to
ultimately re-boot. Tried a few times, with the same, except nothing
in the SysTray after the initial hookup.

Thanks again for all your efforts. Much appreciated!

Well, lo and behold, I've got it fixed. Now if I only knew how. I
installed XP Pro on a new drive, in the old dead system. Everything
worked fine, and decided to plug in the dead drive in the enclosure,
and whadya know, it was recognized! Didn't change anything on it from
when I last tried it on the other machine which would lock up/slow WAY
down. The differences between the systems, which I don't think account
for it:
Old, formerly dead, System: Athlon 850 MHz, 512 MB Ram, new install of
XP SP2 incorporated
Other System, where it would lock up: Celeron 2.6 GHz, 512 Ram, XP
Home no SP2

Now, for the details of what was wrong. As I said, it was finally
recognized, but it said that the M: drive (former C:/boot drive) was
corrupted. But now I could access it from a prompt, so I ran chkdsk /r
I'll paste the results of it below. Anyone have any thoughts as to
what happened to cause the below-indicated problems? Thanks again for
any and all help you provided!
Oh yeah, one more thing. I'm not able to access some folders of the
drive, I'm sure because I'm not logged into it. Is there a way to
change the permissions/share the files, without using it to boot up a
system? Thanks.
