Hard Drive/partition question disappeared in Windows explorer
Hey experts, this is something i am seeing more and more of lately when servicing computers and now it randomly happened to me.
I have a workstation with 6 hard drives ( non-raid). suddenly 2 of them disappeared from windows explorer. I opened drive management and the drives are being detected but Volume and file system type are blank. Everything else is ok "layout "simple", Type "Basic", Status "Healthy ( active, Primary partition"). neither of these are OS partitions
They are both labeled as empty but not raw or unformatted.
*running Win 7 Ultimate 64 bit.
I know not to do anything to them , i have done data recovery before but this is annoying and doing data recovery on these 2 drives would be annoying as all hell since one of them has 2 million + files, 1 tb and 1.5 tb sizes.
i used Active@ Partition recovery to look at the drives and everything seems perfect, i cannot see what is wrong and why they are not being detected.
Any Ideas aside from getting extra drives and copying it all over?

I have seen something similar occur when a Win 7 Ultimate 64-bit system resumes from Standby mode. Normally a restart fixes the issue and the drives are again accessible.
Have you tried restarting this particular machine?

The following knowledgebase article appears to explain the issue i was referring to:

It appears a hotfix may be available for it, not sure if you issue is the same but definitely worth looking into if the drives are SATA disks.

#1 the discs are not failed,
#2 Yes i have restarted the computer and even have changed the plugs around so they are on different sata ports.
#3 in data recovery software every file i have looked at and opened inside the drive is perfect.

Are they on a SATA3 controller? If so, is it Marvell? If so, I know there have been some problems with their controllers.

was simple but yet complex, had to try a few things on my own, noone suggested just changing the drive letter.
You should probably get yourself some decent diagnostics to determine if the problem is a failed disk or an O/S issue.
