Sorry to hear of your loss dude. I suggest getting a sync program to sync your profile and map folder to a usb key plugged into the back of your computer. Cheap enuff insurance to prevent a future loss of data. allwaysync and tarylynn are two freebies.
If your dedicated enough, you can hook the old drive up to your system and use something like diskdigger to recover info. Take ALOT OF TIME, perhaps weeks to do a thorough recovery an is BY NO MEANS exact.
Another option if the circuit is bad as opposed to the hardware portion, you can swap the circuit board with an EXACT MAKE AND FIRMWARE version board and keep on trucking like nothing ever happened.
