I recently purchased an I/O Magic USB enclosure for 3.5" IDE hard drive. Has anyone else used one of these? It works fine with Windows, except of course that Windows can't read the ext2 partitions on the disk I put into the enclosure. CentOS4 can't find the device, much less access the drive -- it doesn't show up in "lsusb" output, although the active light on the enclosure is on solid. I have other USB external drives (Maxtor OneTouch and WD MyBook) that work with CentOS4.
Suggestions appreciated.

---- check what it says about the drive in dmesg after you plugged it in.

---- if you have items of value on that drive, I would hook it to somewhere you believe it works and back it up.
Beyond that, I would reformat the partitions but I suspect that the problem is more severe than a format and mkfs would fix.

I already did that.
The drive works fine if plugged directly into the IDE chain, or when using the external enclosure with WindowsXP. It only gets flaky this way when using the external enclosure with CentOS. Hence I'm pretty sure it's something to do with the enclosure.
