Hi Colin,

Assigning a drive letter did not produce any beneficial effects; it's still
treated as a disk that needs to be formatted, one that doesn't seem to be
formally recognized by the operating system.

If you have any further ideas, I would love to hear them.

Thanks!

During the past 2-3 months I have been waiting for the release of Service
Pack 1 in order that this ongoing problem may be solved. In other words,
I
was told by my computer's manufacturer that Service Pack 1 would most
definitely solve this ongoing "missing hard drive" problem.

I was able to install Service Pack 1 today. The internal 1 TB Hitachi
drive
still did not appear. Bringing up My Computer showed only the C drive
(Disk
1) and the external 1 TB Lacie drive (Disk 0) .

Going back into Disk Management I found Disk 2 -- which I believe to be
the
internal 1 TB drive -- to be unallocated. The following is a snapshot of
the
present situation:

Because I know formal allocation of a drive requires formatting, I
attempted
to allocate the drive and get it to be recognized by Vista without
reformatting the drive. (I assigned it its previous drive letter (X).)
However, this allocation attempt did not prove successful in that I'm
constantly told by the OS that I must format the drive before I can use
it.

Does anyone have any suggestions on this present situation?

Again, this internal 1 Terabyte Drive has a lot of data on it that is
extremely valuable. I do not want to have to erase the drive if at all
possible.

Thanks!

The following is a report on the final situation associated with this missing
hard drive. If anyone has any information on what this technician (below)
referred to as a "involuntary drive swap" I would be thrilled to hear about
it. Thus far I cannot find anything within the Microsoft knowledge base
about it:

I tried a complete reinitialization of the C: drive to see if Vista would
then recognize the internal 1 TB drive. This was recommended by the
computer's manufacturer.

As expected, reinstalling Vista (clean installation) did nothing as far as
enabling it to be able to recognize the missing hard drive.

So I contacted a data recovery service today and we agreed to begin the
attempted process of data recovery.

Even though I was a little hesitant about the potentialities and/or
ramifications, a large number of data recovery efforts are performed remotely
by this service, as long as the operating system can recognize the drive
through the bios. After about 30 minutes of turning over my computer to this
expert (remotely), I was shocked to find out from this same technician that
Vista had performed a type of “involuntary drive swap� when the Lacie drive
(external) crashed, was disconnected, and after we resumed the computer out
of a sleep mode.

Although the technician could not fully explain how it happens (but said
that they have definitely seen it before on a number of occasions when a hard
drive crashed), Vista automatically renamed and re-lettered the internal 1 TB
Hitachi drive exactly with the specs of the external crashed and disconnected
Lacie hard drive.

· Prior to disconnecting the external Lacie drive, it was showing up on the
desktop as "Lacie 1 TB Big Disk (D�. After disconnecting, this drive icon
remained in place whenever bringing up My Computer or within any application.
I thought that this was extraordinarily strange and reported it to Voodoo,
but they said that they didn't have an explanation at the time. They
referred everything back to the fact that "once Service Pack 1 is released,
all of these problems will be resolved..." So I really didn't think too much
about just leaving this icon in place.

· At the exact same time that we disconnected the Lacie drive -- or at least
in association with the very next wake up -- the internal 1 TB Hitachi drive
(drive lable X disappeared altogether.

· Once it performed the swap, it somehow erased all of the files thereon.
How it did this is not clear. The technician also didn't know either.

According to this technician, Vista somehow automatically reassigns one
drive for another in this form of involuntary drive swap. It doesn't happen
that often, but they have seen their fair share. I asked whether or not this
was just for Vista or had they seen it on XP and other Windows OS. The
technician replied that it doesn't matter which version of Windows, "It's
just Windows!" The group of people that I was working with today didn't
sound like they were big fans of the Windows OS.

This technician was able to explain the fact that in reality what I thought
was the external backup was actually the internal 1 TB drive all along.

The ultimate bottom line is that the files are gone. Nonrecoverable --
period.

Since we have been using the internal 1 TB Hitachi drive all along, there is
no recoverable data. The technician searched for any recoverable photo
files, but they were nowhere to be found.

All this time I've thought that I was using the external Lacie drive I was
actually using the internal 1 TB Hitachi drive -- the one showing up as
“Lacie 1 TB Big Disk (D�.

The external Lacie drive has been totally dormant the entire time. It has
not been functioning under any capacities since we received it from Lacie.
One of the primary reasons that I simply didn't know that it wasn't
functioning was because it is located on the opposite side of the desktop
system where I technically can't see the front (to see if the transfer lights
are working from time to time).

This whole situation sounds almost too strange to be true. But there it is.

get it back is to re-boot. The bios finds it just fine, then I am ok. But I
can't put my computer to sleep or it will not be there when it wakes up.

I'm running a desktop system with Windows Vista Ultimate. I have encountered
a problem that I know is being experienced by other Vista users; I'm hoping
there is a workaround.

I have an internal 1 TB Hitachi hard drive (not the C drive). This desktop
system is only about six months old, and ever since I first acquired it I
found that this internal hard drive would go missing after putting Vista into
Sleep or Hibernation mode. Restarting the system would always enable Vista
to recognize the internal 1 TB hard drive again.

However, about two weeks ago this temporary fix wasn't working anymore --
restarting Vista didn't enable the 1 TB internal drive to be recognized.
It's been missing ever since.

And yet this drive is working properly according to Device Manager
(Including having the latest driver).

Doing a Google search has produced a few other threads on the web where
Vista users are also experiencing missing hard drives. Supposedly this
situation is to be directly addressed by Microsoft with the release of
Service Pack 1. Unfortunately, I need access to my internal hard drive now,
not weeks from now when Service Pack 1 is finally released.

Does anyone know of a workaround? Any solution whatsoever... outside of
reinstalling Vista?

Thanks!

I have the same issue on a HP DV9810us Laptop running Vista SP1.

On this laptop, if I put a Western Digital 120G hard drive in the
second bay, it dissapears when resuming from sleep.

I discovered that if I put a Toshiba 120G drive in the second bay
instead, this problem doesn't appear!!

With the WD drive, I tried setting the sleep time to "Never", but this
didn't make any difference.

On further investigation (both drives are known to be good), it turns
out that the WD drive use the default Microsoft SATA device handler,
where as the Toshiba drive uses it's own device driver.

This definitely points to a MS SATA device driver issue.

MS SATA Driver details:
Driver Provider: Microsoft
Driver Version: 6.0.6001.18000
Driver Date: 6/21/2006

I tried running "Driver Update", but Microsoft reported that this was
the most up to date driver at this time (January 14th 2009)

Western Digital doesn't provide any updated drivers (or any drivers for
that matter) from their web site.

Actually it points to the WD drive as not exactly what the SATA driver is
expecting.
The cure can be as simple as flipping a bit in the registry, or as extreme
as using another HD.
I'd talk to WD support.
