Hard drive disappears randomly

I have an IDE hard drive as my secondary drive used for backups or misc files. I also have an external. But for some reaosn on Win7 x64 the IDE (labelled as D randomly vanishes. BIOS sees it fine allt he time. Any ideas or suggestions aside from replacing it as it is still good.

If it vanishes mysteriously, chances are it's not still good.

OP, in (control panel) advanced power settings disable hard drive sleep, or increase the delay. This is almost certainly the cause of what you're experiencing - I doubt there's anything at all wrong with your drive...

Does just placing 0 int he minutes box effectivly disable hard drive sleep?

Is it connected properly to the controller, and any other IDE devices? I'd replace it with SATA II or SATA III (unlikely unless you have a new motherboard) drive and cable.

I just entered a very large number, eg: 999 minutes... working on the basis this represents the time since the last disk read operation it doesn't mean the drive will spin down to dormant after 999 minutes - but will only spin down that long after it was last accessed.

Sure, try zero. That may very well keep it permanently spinning, I just used a large sum because it covered my day to day requirements.

This setting should make no difference to whether the drive is IDE or SATA.

Well, what if you WANT it to sleep to save power/extend the drive's life. Then how do you force it to be seen in the "Disk Management" CP applet?

Usually my drives are there, and they wakeup when I access them. But sometimes they disappear entirely and I won't see them again unless I reboot.

Obviously, this is extremely frustrating - I don't understand why Action -> Rescan Disks doesn't find them???

Hard drive spins down and then disappears from the computer
One of my drives, a Western Digital 1TB Black, will just spin itself down and disconnect from the PC. If I reboot, it will be there but then it will go away. It is Disk 2 when it still shows up, the screenshot was taken a few minutes ago since I don't feel like rebooting at the moment.
