External USB drive disappeared

Hello - I wonder if anyone could offer me any guidance with this.

Following discussion in this thread (http://forums.hexus.net/help-technic...hard-disk.html) I purchased an Akasa enclosure for a seagate drive, which I was connecting with a USB cable to a PC running XP sp2. I used it for back-ups of my main drive.

All was fine, until one day I noticed an error message from my back-up software saying the disc was full. I ignored this initially, as I was busy, and came back to it later in the day. The drive appeared to have disappeard from Explorer, and powering it on/off, disconnecting/connecting, changing USB ports/ cable etc didn't make any difference. It wasn't showing up when connected to a laptop, either.

On closer inspection, I found that although it didn't appear in Disk Management, it did show up as an anonymous USB device in Device Manager (likewise it was listed as a storage device under USB devices).

Presuming the hard drive had packed up, I sent it off to Seagate for a replacement. This has duly arrived, but doesn't seem to have made any difference.

Does this mean the enclosure is knackered - or am I missing something else obvious to try? I've disabled, uninstalled and reinstalled the drive, with no joy.

Any suggestions appreciated! Thanks.

Anyone? I'd rather not return to enclosure to Scan if there's something obvious I'm missing.

u really need to test it on another pc to be sure

Thanks - yes, I've tried the drive in another PC and it seems fine, so I think it must be the caddy. In the abscence of anyother ideas, I've posted it off to Scan today to get a replacement.

Cheers.
