SATA hard drive not seen in BIOS

Hello,

I "lost" my SATA hard drive yesterday, I had Windows XP 64 bit installed on it, but as I found driver support for XP64 very poor, I decided to install a further 250Gb PATA drive and bought a new copy of Windows XP Pro for that, the intention being to transfer everything over at my leisure. For 3-4 months I have been booting from either hard drive depending on what I wanted to do. Whilst on the XP64 operating system yesterday, it suddenly froze, CTRL ALT DEL did nothing, so I pressed the reset, on reboot, my SATA hdd was no longer seen, so I booted to the PATA hdd, installed VIA RAID and found all my files still on the SATA drive, why would it suddenly become unrecognizable by the BIOS?

I have now disabled the SATA boot detect option in the BIOS to get rid of the annoying "Drive could not be found, the BIOS is not installed"

These are my system specs... AMD Athlon XP64 3500 CPU, 1GB ram, Maxtor SATA 250gb hdd, Maxtor PATA 250gb hdd, ASUS A8V deluxe mobo.

Help please!!!

If the SATA drive had a failure involving the boot sector, it would fail to boot but could still be readable as a secondary drive.  Run the manufacturer's disk diagnostic on it, which you can find on the UltimateBootCD, to see if it has a problem.

If the BIOS no longer detects the drive, and it once did, reset the Extended System Configuration Data (ESCD) in your BIOS if you have such a setting available.  If not, try clearing the CMOS (see your manual) and reboot.

Also, check your drive cable...

seen where, in the bios, the post screen, or on the dual boot menu screen?

"so I booted to the PATA hdd, installed VIA RAID and found all my files still on the SATA drive"
it's odd that xp 64 can read the drive in windows if the bios can't see it

seems like the bios is ok, but be sure to check it to see what the bios settings are for both drives
if the bios is fine, then boot from Recovery Console, & run bootcfg (follow instructions for bootcfg in this ms kb article:   http://support.microsoft.com/kb/314058/en-us

Hello,

Thanks for all your comments, but to cut a long story short, the drive must have been failing or developed a fault in pagefile.sys. Sometimes the computer had a job reading files on the drive, then "poof" the drive was gone, but seen again on reboot. In an effort to save all my files, I tried copying the entire drive, it kept getting stuck on pagefile.sys, then would freeze. I rebooted and then just singled out the files I wanted to keep, before simply reformatting the drive, it now works perfectly ok and I have not lost anything I wanted.

Thankfully, the drive was no longer needed as a boot drive, so I took the easiest option and didn't use any diagnostic tools.

Does a corrupt pagefile.sys file cause a drive not to work?

Thanks

Kevin

A corrupt system file (including pagefile.sys) can prevent a system from booting from that drive, but you could still have connected it as a slave drive in another system and read from it.
