I actually had that same problem, and I stuck the drive on a USB 2.0 powered hub and it seemed to clear up.

Have you tried mounting the drive with Disk Utility? I have found a few flash drives wont show up until I go to Disk Utility and find the problem drive right click and choose mount.

"Well, I reckon its an incompatibility between the chipset in your USB disk and 10.5.

I too had a (powered) enclosure that worked very reliably with 10.3.x on a PowerPC Mac mini, and then became very unreliable as soon as I'd upgraded to 10.5. (I don't believe in coincidental disk failures.)

Short of spending a lot of effort with Apple Support (which I've done previously on other disk-related issues, and still didn't get the problem fixed) I think you'll just have to find another enclosure and swap your disk over."

"You haven't specified what type of machine you have tried it on (i.e. laptop or desktop) and what type of external USB drive you are having problems with.

I'll assume for now that you are trying to connect a 2.5"" USB drive, so it could be the case that the USB port on your mac is unable to provide enough power to the device.

I would recommend trying a different port or using a USB cable that allows you to draw power from 2 USB ports. Something similar to this:"
