basically, it sounds like OSX had touble mounting the external disk, accessing it.

have you tried plugging it in again since? open disk utility (in your applications folder, possibly under Utilites). is your disk shown in the column on the right? if it is, can you mount it from there?

if you can't mount it, try Verifying, then repairing the the disk, this could help a lot if you can do this. then try mounting it again.

in future, always eject an external disk before unplugging it. it can corrupt disks if you don't.
 
Ejecting the disk first ensures that there is no data being read or written when you unplug it. If something at all is being accessed, it can really screw up the disk's directory, which can make it not mount the next time you insert it.

Also, if you run Repair Disk on it, Verify it again to make sure everything's fixed. Sometimes, it repairs just enough to let it see the next problem.
 
Yep -- disk reads and writes are "cached," meaning that when you copy a file to a drive, the file is not immediately written to the drive but rather kept in a cache (either on the drive itself or in the operating system). It is then physically written to the drive whenever the OS or drive deems it necessary, or when the drive is ejected.

Ejecting a drive ensures that cached data will get properly written to the drive.
