As i mentioned to the original poster, did you go into the Control Panel,
Administration Tools, Computer Mgt, then Select Disk Management.

Make sure you do NOT have any files on the disk that is giving you the
problem..

Now use the Disk Mgt to set up the disk...

See if this corrects the problem, and let us know...

I've not seen this myself.. So I'm very curious about this and if this will
fix it or not...

I'd like to join in too. My second SATA drive disappears from time to
time.
It seems to be when it is being heavily used. I have to power off and up
then
Vista sees it. This time, I donwloaded the Data Lifeguard rom WDC and ran
the
Write Zeros test. No problem there. But, Vista wanted to format the drive
afterwards. OK, but in the middle of the format, the drive disappears.
After
powering down and up, Vista does not see the drive but the Data Lifeguard
program does.

In my searches, this seems to be a consistent problem in Vista and so far,
no resolution exists, at least that I have found.

Roy, I have tried that many times, to no avail. Recently, I installed WDC'
Lifeguard and it runs all of its tests without a problem. However, after
writing zeroes, Vista wanted to format the drive, which I let happen. During
the middle of the format, the drive disappeared and I cannot get Vista to
recognize the drive at all now. My bios sees it and Lifeguard sees it but
Vista does not. Now I am really in a mess.

FWIW, I just finished installed SP1, initializing and formating the disk, and
running my test case that usually caused the failure in the past. It ran
successfully. Should I conclude that SP1 fixed the issue?

Vista SP1.

I have very similar issues...My PCis a very souped up quad-core wtih 4GB RAM and an nVidia GTX card, an 800w power supply to handle all necessary accesories. I also have a 5 year old Compaq PC that I was about to throw out. However, the new PC which has Vista Ultimate has problem recognizing my external drives. I ave 2 internal drives, a Seagate 500GB and 1TB drives that are recognized and work like a charm. The problem is that I have 2 Lacie Mini External drives that Vista recognizes, but a few minutes after accessing the drives they disappear, sometimes together, sometimes one at a time. Once they disappear, they go to the 'unknown device' section in the control panel and when I click on them Vista asks for a 'driver update', but the problem is that these drives, like many other drives, do not come with drivers...once you format them, under XP and Vista, they automatically work. I used these drives for more than a year under XP and NEVER had a problem. and when I attach them to my Old PC, still no problem....I installed SP! for Vista, and still the same problem...I do see that all over the Internet other users are having the same problem too, but no on has come up with a concrete solution. Can anyone help?

This is what I did for vista.

Control PanelAdministative optionsComputer Management

Under storage it should list primary drive and an unallocated drive.
Right click on the uallocated drive and allocate it. It will ask you if
you want to reformat the drive, I said "no" to this but it did it any
way. So I lost everything on the Drive, but I see it now. Hopes this
helps.

This did not work. The sata drive on my ultimate 64 is not showing up
most times. This is a common problem and when it doesn't show up, it
doesn't show up at all. Its frustrating as hell as u have to shut down
and turn back on the computer and sometimes it appears. Now going into
disk management does not help, as the drive is not showing up. I have
my system disk is sata and partitioned, so i now have drive C, D, and an
E. Only C shows up all the time, yet D and E do not. Someone must have
figured this out at this point and i have removed updates and its hard
to pin point as sometimes it shows up and sometimes it does not. Any
one with any actual results that know of what is happening please fill
me in.

I did the in the Disk Manament shows the D drive but says it's not
accesable and it's not labled propplery i can't format it it tells me to
to insert a disk in the drive

I had shut down my computer turned the power off disconnected all the
hard drives cut the power and the cables connected both hard drives
master and slave drives and from the mother board everything then waited
10 mins hooked everything back up restarted the computer same thing
after Vista reloaded I'm not doing a fresh reinstall it's a waist of
time plus backing up my data each time vista screwes up not worth it.

when I had win 95 98 / 98 second edition win xp pro could reset it
there something screwed up in the protection mode system restore and
shadow won't put it back eaither.
had a Licenced Microsoft PC Specialist look at it he said it's fked I
do believe we all got beta versions passed off as the real boxed
versions of vista he said the same thing his vista seams crashing more
thing's stop working auto update re writeing his data he's said Ither
fix it microsoft or don't bother putting out any more prerealeased bata
version passing them off and the real macoys.

whom ever there getting to do the fix auto update better go back to
computer school and learn how to re write software propperly all hes
been getting is screw ups from the microsoft site after another and I
stopped all my down loads cause i'm getting the same thing.
