Can't see the logical drives in My Computer (External HD)

[bdyaniv]

Hi,

I have an external HD.
Recently I can't see its drives in my computer.
I can see the drives in Device Manager and all its tools (Defrag, Disk Managment...)

I don't see any problem with the drivers in the device manager, I also uninstalled and rollback the drivers but same problem...

Help

Just found the problem in a diff thread...

I didn't have logical drives, somehow they are all erased, any explanation ?
