I am using an Asus AN8-SLI Deluxe motherboard. C:\ & D:\ drives are Western
Digital Raptors 10,000 rpm units. E:\ & F:\ are Western Digital & Maxtor 7500
rpm drives. All drives are SATA based and use new lock on connectors. None
are setup for RAID configuration. Okay, here is my problem. Every few weeks
my C:\ drive is not found and is missing from the bios listing. On other
occasions all drives are shown in the bios but my OS is not found. Sometimes,
after the machine has been running for a while, everything is lost and it
reports that it cannot write to the drive. All the other drives are always
available, only the C:\ drive gets dropped. I have run all tests on the C:\
drive using a WD test and everything comes back positive without any errors.
The temporary cure is to disconnect D.C. to the other three drives, check all
connects, reboot at which time the C:\ is found and Windows XP Pro. 64 bit
OS loads without any errors like nothing was ever wrong.
What am I doing wrong here? I have never knowingly loaded any SATA drivers,
are these required without RAID configuration? I donâ??t have any errors
showing in Device Manager. Any suggestions would be appreciated.

If it is not showing up in the BIOS listing....sounds like it is not an OS
issue, but rather a HD and/or BIOS issue.

My first suspect would be the hard drive (next BIOS) as well.

How long have you had the board and which BIOS are you using. I have the
same board, and you don't need drivers for SATA unless you are using RAID.
I had a lot of problems early on with BIOS issues, but I think I have 1016
now and it has been very stable. One other possibility if you run without 3
drives connected and it works, maybe you have a power supply that is too
small.

SORRY ABOUT TWO POSTS WITH SAME QUESTION. FORUM SAID MY FIRST POSTING HAD
ERRORS SO I SENT A 2ND. TIME.

Thanks Thanks John & Charlie

1. I started with the SATA cables supplied with WD drives then switched to
newer locking cables. No change.
2. Bios is 1017 which still doesnâ??t allow me to determine the drive order.
1016 didnâ??t allow this either. Does your bios list all drives and with + or â??
key move them around? If memory serves my ASUS CD will not now let me return
to an earlier/lower bios flash.
3. Iâ??m thinking of dumping drive D:\ contents and switching it to boot drive
with a fresh XP 64 load to see if problems cease.

What do you think? Maybe a new bios chip?

ANTEC NEOPOWER 450 W. PS. Should be fine and surely only one or two drives
spin at one time.
