One of hy HDs not recognized

[riffwraith]

In my Vista computer, I have 4 HDs.

2 SATA (one of which is the OS drive), and 2 IDE. The second SATA, which is just data is no longer recognized. I pulled the HD out of the case, and put it into an enclosure. No go, even tho other drives are recognized when in that same enclosure. The HD spins; I can feel the vibration. There is no noise whatsoever (ticking, etc.), but I can in fact hear that low-level high-pitched spin-up noise when I plug it in.

Is there anything I can do to access the data on this HD? If not, it's not the end of the world, but I am hoping to not have to run out and buy another HD, and xfer data over from DVDs.

Thanks for any insight.

Right click on computer > Manage > Disk Management [under storage]. Do you see the hard drive listed? If so double click on it and give it a drive letter. Also check under device manager. Have you tried it in another computer?

Also try a diagnostics disk from the manufacturer.

Sorry, should have mentioned that I do not see it in comp. mgmt., nor in the dev. mgr.

Where to point the diag tool to, if I can't point it to the drive?

Thanks!

With the drive hooked up normally, is it shown in the BIOS or during the POST?
