I have 2 HDDs in a RAID 0 software array using nf4's nvraid (2 x 300 MAXTOR SATA). Recently my computer froze and I rebooted it to find out that windows lagged out on the boot screen until chkdsk came up. Chkdsk froze on phase 1, 4% in (stayed on 4% for 2 hours). I have been searching around the internet and found some articles to suggest that CHKDSK'ng a RAID array may screw it up because of how striping works. Here is a case of a RAID 5 hardware array and CHKDSK: http://ask.metafilter.com/65106/Did-chkdsk-eat-my-files This place says dont do it: http://www.quetek.com/RAID_mistakes.htm I have booted it up to Windows Recovery Console and gotten access to the files, and everything appears to be good. Im using the nvraid drivers in the Windows Recovery Console to read the drive. Should I go ahead and run a chkdsk? Or should I do a reinstall of XP? I understand that RAID 0 is a risky setup, and I understand I could lose all my files. I just really like this install of windows and the files are worth enough to me to try to fix this problem. Any help or input would be appreciated!
