Hi,
yesterday my Bootsector and/or NTFS Filesystem got corrupt under Win XP. I am not able to boot anymore from my S-ATA harddisk. After booting, some seconds later Windows resets my PC and boots again and again and again.

When I tried to reinstall Win XP or using the repair function I always got a blue screen with an ntfs.sys error.

In some newsgroups I read that the filesystem might be corrupt and maybe the bootsector is not working anymore and this can be fixed with Knoppix using the ntfsfix command. Normally there is no chance to get access to the disk via Win XP in this case. I tried to get access to my harddisk via Knoppix 3.3 I have success. I am able to see the 2 partitions and all files on it.
I go to the console and typed in

ntfsfix /dev/hda1/

but everytime I received an error, that this command FAILED and that I have not permission to this harddisk/partition or that its corrupt. I have to use chkdsk to correct this. I am a Linux/Knoppix Newbie and dont know how to use the chdsk command. I used "chkdsk /dev/hda1" but the console says that the command chkdsk is unknown. Is someone able to give the correct command for this ?

I noticed that the harddisks normally are only open for reading under Knoppix. I go to the properties and changed the status to readable/writeable for both partitions of this harddisk but also this gives me the same error with ntfsfix as shown above.

I would be very nice if someone can help...
