I'm using a USB 2.0 Hard Drive enclosure.  I successfully managed to use it on my first attempt (stored a bit of music on it) but now it is not listed on "My Computer."

When I go to "Device Manager" it is listed under Disk Drives - Visual Disk USB Device.  Its properties state that it is working properly.

I've tried uninstalling the DRIVER, but this has made no difference.  As a bit of a novice, I'm sure there is an obvious answer to this problem - please tell me what it is.
Right click My Computer and select Manage...then Disk Management...
Find the drive and right click it and select Properties...
Report back with the results...

Hopefully it's not listed as RAW...The good news is it's not listed as RAW.  Unfortunately, it's not listed at all, just the (C:) & (D:) drives. 

It's as if it isn't there!Whose enclosure is this and do you know what type of drive is in it ? ?

Try hooking it up to a rear USB port...
Check the on/off switch if applicable...
Re-install the driver without hooking up the drive...It's a Nlink "Pax" 120GB Hard Drive Enclosure.

I've already tried what you have suggested - no luck.I just joined the forum because I had the same problem as you. My laptop hard drive had died (I thought) a while back. I bought a USB 2.0 external enclosure (X Media), but could never see a drive letter on my XP laptop, and I would get  a "drive can't mount" type error on my Ubuntu desktop.

The USB cable I'm using has TWO USB connections on one end, one USB connection on the other. Anyway, to make a long story short, I tried what the other poster said - another USB port on my laptop - and it works!!!!

I always use the same port, but trying the other one (and maybe the other USB connection on the cable, I'm not sure) actually worked!

I hope that this simple SOLUTION may work for you too.ndanger,

I also realized that I MIGHT have now successfully been able to see the hard drive because I pushed it further onto the IDE connection. It had been a little loose before.

After getting a firm connection, I still couldn't see it on my Ubuntu desktop, but either having a more firm IDE connection or using a different USB port worked for me.Not exactly a brand that inspires confidence...is it a 2.5" laptop drive in there ? ?
If so dis-assemble the enclosure and recheck all connectors...

How old is this unit ? ?
