If the drive is still OK server reinstall should retain all data. Data that is not duplicated AND was stored on the D partition of the original system disk will be lost when you replace and do a server reinstall. Data which was not duplicated but stored
on any of the other disks should be retained.
If you want to do a server reinstall on the original system disk I strongly advise you to run chkdsk /f /r on both partitions of the system disk (command prompt, chkdsk X: /f /r where X = Drive letter). If the system doesn't boot you can try and mount
the disk in another system. If you don't see any partitions when mounting the disk in another system there's a more serious issue with the disk. If you really need the data you should seek epxert advise, if not you could also try and fix the error yourself,
for example using a program such as Spinrite, or try and get the readable data from the disk using a program like
PC inspector file recovery, then use the "manual" procedure as described in
How to recover data after server failure.
Anyway, Good Luck!
