external disk drives

I attached an external hard disk to my computer. The device was recognised, and the disk manager reported it to be healthy and ready for use. When I checked the properties of the disk I saw the following: free space 0 bytes. Used space 0 bytes. File system: raw.
I doubled clicked the drive, and was told that disk needed formatting. When I tried, up came message: This drive cannot be formatted. Manufacturers say disk was formatted at factory and that my computer isn't reading the file system. I think the device is faulty. Any ideas?

TRy plugging into a different USB port, direct off the motherboard, use a rear port and donot connect via a hub.

See if the drive can be read.

Thanks for prompt response Fruit Bat. I have already tried what you advised without success. I have also tried attaching several times, and starting the computer with device attached. Unfortunately the limit upon length of messages does not permit me to list everthing I have tried.

I have an idea but don't wish too appear more foolish than normal.

Refresh USB Ports
In device manager Uninstall EVERYTHING under the heading USB,
reboot the PC let XP find and install new hardware.

Daft as it may sound it could be the caddy itself! I had the same problem, removed the drive and physically installed it to the PC - worked fine. There was not enough power to power the drive up, but I could still see it. Got a new caddy and all was fine.

Good luck

Hullo Woodchip. I have already tried making it Active in Disk management, but that made no difference, I'm afraid.

Hullo fishface113 I hate to appear so ignorant, but I've no idea what a caddy is.

a caddy is a hard drive enclosure, commonly used to house a internal hard drive, so it can be used as a external hard drive
