My hard drive works fine when connected to a notebook through an adapter, but when I put it back in the notebook it came out of, it is not recognized.
Any ideas on how to fix this?

Update:

It started as a recovery virus so I took out the drive to get the data off of it then put it back in to reinstall XP pro, it was time for a reinstall anyway. It came up hal.ddl was missing, when I put the OS disk in, it didn't find the drive. I am formatting the drive now to see if that will help.
