External USB HDD isn't connecting!
I normally used my external hdd on my Mac and decided to back some stuff up that I had on my PC. So I plugged it in, and nothing happened. I just get a "Unknown Device" pop-up and the Device Failed to Connect sound. When I plug it into my Mac, nothing happens either. It doesn't show up in the Finder or Disk Utility.
I took the drive out of the case, hooked it up to my desktop and saw that all my files are still there. So this has left me to believe that it's a problem with the USB host controller on the drive case. Is there a way to reset or repair it? Additional Info: The drive runs only on USB power (dual USB tip cord) and is a 320GB Western Digital Scorpio Blue. Thanks.

maybee try getting a cheap sata to usb cable and run from your board outside the case to the drive or alternativly get belkin or similar usb hub and run from your io shield and then the controller on the board will see it

Flipping an external drive from Mac to PC can cause issues - especially if it was formatted on the Mac, since a Mac uses HFS+ as a drive format, while a PC (XP? Vista? W7RC1? heck - it could even be Ubuntu ...PC is not particularly descriptive) uses FAT (less likely), FAT32 (common for external drives), or NTFS (more common for internal HDD).
Unless you are using something like MacDrive, a PC is not going to recognise the OSX formatted drive natively. In fact it MIGHT prompt you to reformat so that the drive can be used. Did you get a prompt asking you to "reformat" or "prepare" the drive for use? If the drive is lost, you might want to try reformatting it on the PC as a FAT32 drive - at least then it will be recognised by both machines.

The drive is perfectly fine, and it's been formatted as FAT since I first got it.
Should I just look into getting a new external enclosure for my drive?

What kind of HDD is it, IDE or SATA? Can you connect it to the motherboard of any computer?
Something isn't working. Find out what. It can only be the drive, the usb adapter, the cable, or the power supply (if there is one).

I said that the drive worked, it's just the USB controller that isn't working. It's a SATA drive and everything is still on it.
I just want to know if I can fix it or if I have to go buy a new external enclosure.

It depends on where you've got it plugged in - I presume it's a USB bus-powered drive. Some ports don't output the full 0.5A, 5V voltage required by the vast majority of bus-powered drives.
These include shared ports on DIY cases, many USB hubs, etc. I would say plug it into one of the ports directly on your PC's motherboard (i.e. the back) and see if that works. If that doesn't work, then it's probably time for a new enclosure. Last edited by ArmpitOfDeath : 08-16-2009 at 01:10 PM.

None of the other ports worked. Alright then, I guess I'll just buy a new enclosure.
