[Probably]
The best you will be able to do is repartition around the bad sections of the hard disk....., the reason that the w2k probably crashed was because in all likelyhood the [b]entire[/b] hard-disk is -(badly damaged). There is little remedy for this bar trying to repartition around the (bad) sectors of the harddisk though how effective this will be is debateable as, if one sector on your hard-disk has become corrupt for some reason the likelyhood is that soon the (bad) sectors will start to increase for the same reasons the first sector went bad if you catch my drift?

Btw - Ext2 and reiserfs probably wouldn't pick up on a bad sector on your hdd sooo more than likely your linux partition is fscked too. There is a dos utility that you could check the disk with which should tell you if hard errors are confined to former windows partition or are disk wide .....
Here is a boot disk which should have a program called gwscan - run this and try and find out if disk errors are disk - wide

 Hi,
 
 My laptop (dual-boot Win2K/Mandrake 7.1) suffered a fall recently and the
 Win2K partition suffered hard errors, making it unrecoverable. The Ext2
 partitions survived, however with no data loss (had to fsck the partition),
 so waht I have done is I have removed the Windows partition, created a new
 one in its place with fdisk, and created a filesystem using mke2fs on it.
 The filesystem is created OK, but using badblocks to check for bad areas on
 the partition takes an interminably long time, spewing lots of IDE
 controller errors. My question is - is it possible to use this partition -
 ie can the ext2 FS make use of a partition that contains hard errors and is
 smart enough to avoid the affected areas? BTW, I created the FS without the
 -c option (check for bad blocks), should I delete the partition and
 re-create?
 
 Cheers
 Rory
