Bootcamp partition corrupted ??

[Tex-Twil]

Hello,
yesterday I installed XP in bootcamp anf everything was working fine. Today I wanted to boot to XP but I had a "NTLDR missing" error. I googled for it and it looks like there is a problem with the partition.

I had a look via OSX to the XP partition and I see that almost all the system files are missing in this partition:

jan:~ jan$ ls -ail /Volumes/Untitled/
ls: ._.Trashes: Input/output error
ls: .fseventsd: Input/output error
total 64
    5 drwxrwxrwx  1 root  admin  4096 Dec  7 18:28 .
22958 drwxrwxrwt@ 5 root  admin   170 Dec  7 18:17 ..
 3908 -rwxrwxrwx  1 root  admin  6148 Dec  7 18:28 .DS_Store

 3753 -rwxrwxrwx  1 root  admin   211 Dec  6 13:23 boot.ini

what the hell happened ?

Well I reinstalled bootcamp so I lost all my data. I would like to know what was the reason for that
