Daily Doings at the Line of Death Bar & Grill

On Monday night, I was doing a backup of my laptop's hard drive using an external hard drive. (Damn, those things are handy!) Then, in the middle of the process, the power cord to the USB card got pulled, and the backup stopped.

After several rescue attempts, including reinstalling the driver, I've come to the conclusion that the USB connection of the hard drive is kaput.

Now when I try to connect the drive, I get a Blue Screen Of Death. I'm thinking I may have to reinstall the Add Hardware Wizard, or all of Windows 98. What's the command to "heal" Windows 98 and reinstall only the corrupted files?

BTW, I checked the external drive on another computer, using the external hard drive's FireWire connection, and the contents are OK.

So now I have several options, some of which involving spending money.
1) Use another external hard drive to perform this and future backups.
2) Buy another hard drive enclosure.
3) Buy another hard drive enclosure, identical to the one that went kablooey.
4) Buy a FireWire PC card so I can continue to use the drive.
