Unallocated Drive

Help ! I have got 2 drives, C & E, and everything was working fine till one morning I got a blue screen on start up, memory dumping etc etc. Turned out to be a corrupt memory card (I got 2 of them). Card was replaced but sadly lost all data on my C drive in the process ! Unfortunately, my E drive (still containing 60GB of data !) is now no longer accessible but it does show up in device manager with no problems. Under drive manager it shows up as unallocated. So far, all the advise given meant to reformat the disk and subsequently I will loose all the data of my E drive as well !! Isn't there another way without having to loose all the data ? Also, I've got a little programme monitoring the temp of the 2 drives and the E drive does show up on the result screen, so it's there, got power etc etc
