[Wlug] Missing /dev files

[Chuck Noyes]

Hello,

I had mounted an external usb drive /dev/sdb2 onto /media/sdb2 and was
coping several mega-bytes of files to it when I got some I/O errors.
Then I noticed that all of my /dev/sdb* files were missing from /dev.

When I do an ls -al /dev, all the files are there except the sdb files.

How can I get these back? I'm running Ubuntu 'gutsy' 2.6.20-16-generic.

Thanks,
