i am having the same problem just like u do. if anyone can help me out to solve this, that would be great.
Here's my problem, for no apparent reason my hard drives are not listed under the disk management utility(cd drives appear). They appear on "my computer" correctly, they show up in "Device Manager"(and I have no yellow question marks).
In addition in "disk defragmenter" they appear but I'm unable to even run the analyse command(using other software I'm able to defragment them).
I've tried EaseusParttion Manager, but the drives don't appear as well.
I'm not able to use USB drives as well(I assume it is related), they appear in the right side of the task bar and they appear in "device manager" but not in "my computer" nor "Disk Management"...
I've googled this over and over again but with no results.
I'm using windows XP with SP3.
Thanks in advance
