win7 won't recognize hard drive, bios does

I can't figure out why windows 7 will not recognize two of my hard drives from my old computer. I built a new computer and am transferring all three hard drives data onto my new hard drives. The first one worked fine, it was a hitachi deskstar, but the next two, which are both WD raptors, aren't even being recognized by windows 7 but are both recognized in bios. All connections are SATA. I have tried to look under the Disk Management, but they do not appear. Any ideas?
 
Oh boy, this is a interesting one. Soo your BIOS shows the drives. When you go to install W7 it doesnt find the drive ?

it should show in disk management .

I say try installing motherboard drivers chipset drivers, let us know and also put down your rig specs.. thx

and i've installed all drivers related to my mobo, i have windows7 installed on my ssd, but when i try and attach my old hdd to transfer the data they don't show up in windows
 
Hmm I want to fix this problem for you.. This is very strange.

Ok try plugging it into another SATA slot and also try a different cable if possible.
 
Im thinking you should try a third party app.

Partition Wizard google her in and get it.

they have a trial ,, see if you can find the drives in there and format. gl
 
I will try a different SATA cable later tonight; although, I don't know why this one wouldn't work when it worked on another drive. I can also hear the disk spin up, so I know it's at least getting power.
 
Different SATA cables didn't work. I don't want to format the drives at this point anyway, since they have data on them I want.
 
You might have better luck with USB. Sometimes a drive not recognized on a SATA port can be accessed from an external enclosure. The treouble with a Raptor is it mignt not physicly fit inside an enclosure. Don't they have some cooling fins connected to them or something?

Not the first time that I've heard that Win7 is incompatible with Raptors.

That doesn't mean it's true. OSes support hard disk controllers, not disks themselves. As long as the controller works (and there's no firmware bugs related to specific drives) the OS can use the drive just fine.

I finally got it to recognize the drives in disk management, but I cannot do anything with them, not even format. I right click and goto properties and windows says it's running fine.

You need to right-click on the volume, not the disk, in order to do anything with it.
 
CP/Admin Tools/to Disk Management should show the drives, and you may have to change the drive letters for them to blossom in Windows. Sometimes they get assigned drive letters that are already in use, and then they do not appear.

You can also try this - put one in an external case (SATA) with a USB link. Hot plug it and see if Windows picks it up.
 
Try the specific suggestions from corkyg and nothinman, if it doesn't work, show us a screenshot of drive manager
