RAID 0 corruption?

[imported_Stin]

I just setup a RAID 0 array with 2 160gig maxtor drives on an nf7-s rev2.0 motherboard (uses Sil 3112A sata controller onboard). Anyways it seemed to be working great for about a week. I downloaded the latest drivers from SiI and ive got the 4.2.47 sata bios which is just 1 version older than the newest, and im noticing some corruption issues. BT downloads are having segments fail hash check and redownloading. Sometimes they just stop and say download corrupt (using BitTornado). I was doing some DVD authoring yesterday and noticed that the video had lots of artifacts when I went to view it. Green squares etc popping up. Just now I went into my bios and loosened up my mem timings (now at 11-8-8-2.5 with pc3200) Which was memtest86 checked a while ago and did 2 passes just fine at tighter timings. I also changed the p2p discard time to 1ms from 30us in the bios. I then rebooted and still got failed segments in my torrent. I havent noticed any massive corruption but it seems to be failing to write correctly periodically. Any suggestions for ways to solve/pinpoint the problem?

List your full system specs. Hard drive corruption can come from bad memory or from a failing hard drive. Your mem timings are a little ackward, you should try something more like 3-4-4-8. 2 passes of memtest isn't really enough to rule out bad memory. Also, the artifacts sound more like an overheating video card, shouldn't be hard drive or memory related. What video card do you have, and what do you have for a power supply?

RAID 0 in the long term is a loser with no gain. Your data is striped between both drives - any failure on either drive and you are hosed.

RAID 1 (mirroring) is the better choice.

You should rebuild and go with RAID 1, 0+1, 3 or 5. (The most common ones)
