I had this problem. After uninstalling & rescanning as described above, drive still did not show up in Win, but tit does in BIOS.

Going into Computer Mgmt > Device Mgr, the drive showed but had no letters. I assigned letters & then everything was fine.

Using a USB hard drive enclosure worked on the Magnetic Technologies hard drive, I was able to copy the files to the new Sata WD hard drive which worked fine. The old Hard drive said it had 38gb free space of 465gb, but looking at the files it seemed less than half full and windows was unable to finish checking the drive for errors so I assume it was a bad hard drive.

I tried most all of what I have read so far. My 500gb internal sata hd worked till recently it stopped working. It displays correctly in bios but not in windows explorer or disk management. I have important stuff on this non accessible hd and now realize I do not really have it backed up. The 500mb hd is Magnetic Technologies. I ordered another 500 gb Western Digital hd and will buy a usb external sata enclosure tonight. Hope that allows it to work. If that does not work I am considering professional data recovery.

I was hoping this would be my answer too. Not so.
I added a second SATA drive. BIOS see’s a device but doesn’t capture any details. XP (Device Mgr and Disk Management) neither see the
drive. I’d tried scanning for new hardware, Add Hardware, booting from setup disk. Also tried changing SATA ports on the MB. Nothing.
Anyone have any other ideas?

I have a similar problem. My Maxtor DiamondMax10 200GB is recognized in the BIOS but missing in Windows 7 after boot up. When I do “Scan for hardware changes”, it’s immediately found and accessible. But after reboot it’s gone again. Anyone knows how to solve it? I’m using AHCI driver from Microsoft. All my other HDDs/SSD are detected with no problems. Or could it be a firmware problem of this (older) HDD?

Thank you. After countless google searches, forum, and blog browses I landed here. “Scan For Hardware Changes” just saved my life.

Thanks again.

ps: I’m using Vista, not Win7. So all I had to do was hit that Scan For Hardware Changes and the new drive showed it’s face, and I was able to initialize and partition it in the Disk Management. (though to be fair, I had been fiddling around with things for a while (see: countless google, foru.. blah blah) so I might have altered something during that time.
