Partition gone after running chkdsk, XP can't access one partition

Hi!

I left my PC running to use Bittorrent while I was at work. When I came back there was some error message about access to the hard disk and PC was frozen.
I have 2 WD drives in RAID0 (SATA) for XP and other stuff and 2 Seagates (SATA2) in RAID0 for everything else. One partition from the Seagate array is bad.
I turned PC off and back on. Chkdsk ran on the drive I was downloading torrents into (Seagate drives) and then XP would not boot, but just sit there with the progress bar scrolling.
I was able to boot into safe mode and the partition that Chkdsk run on is gone. Chkdsk results:

I used Partition Recovery and I could see that my files are there. That software can only copy files to another drive and I don't have a drive that big to copy that stuff. Also I used the search for partition feature and it found the partitions, and set the 1st one (the one that's missing) as active. Now the partitions show up but Windows explorer can't access it one of them. Other partitions on that drive are fine.


Is there something I could us to fix it without copying someplace else (it seems like file system is broke)?

What does setting partition as active mean?

Thanks in advance
I have XP Pro SP2, 2GB RAM, 2 WD Raptrors in Raid0 (these are ok), and 2 Seagates 300GB in Raid0 (total 600GB and the broken partition has about 550GB and 250GB is used)

If the partition somehow got "hidden" then u may have to set it to "active ". several utes are available to download on a trial basis that will allow u to do this. my fave is pqmagic do a search

 

Is "pqmagic" a Partition Magic from Symantec?

 

I tried Partition Magic 8.0 and I checked that partition for errors.
It shows error "1507 bad file record signature" and as soon as it finds that 1507 error, error box pops up saying "error #7. operation cancelled by user" and quits the scan .
I updated PM to 8.01 and same thing happens.

 

Seems like a bad block on one of your Seagate hdd. Get another HDD & copy your data to it. That's the best I can suggest.

 

I ran Spinrite on it in level 2 and it found no problems so I assume its not a harware problem. Also these drives are about 2 months old.

 

AFAIK, RAID 0 is one (virtual) drive that is built from two drives (data is written part to one drive and part to the other and so virtually doubles the speed of access of data). The downside is that a problem anywhere on either drive will cause the system to break down.

Spinrite may say there is no physical problem with the disks. The problem may be with the file system which is analysed best by Chkdsk. Chkdsk seems to say there is a problem.

Suggest you check the information/troubleshooting at the manufacturer of the RAID controller.

See if there are specialized RAID forums or usergroups.

(An "I told you so" , sorry) go for RAID 0+1 if you want speed and have data that you cannot afford to lose.

I'm pretty sure its the problem with file system since other drives on the motherboard's SATA2 controler work fine.
Chkdsk errors out when trying to run it on that partition.

"The type of the file system is NTFS.
Unable to determine volume version and state. CHKDSK aborted. "
