Raid Failes?? Drive works fine?

Ok, so im downloading a file on my system:

vista 64
raid 0 (4 drives)

and i 1 of my drives fail in my raid?? so im thinking the hard drive is bad? but i reconfigure my raid.. delete it and re-create and now everything works fine?

what would cause that? any ideas? should i still replace that drive?

umm not to sure about drives..but i would definitely give that drive another chance...try downloading speedfan and check the drives performance and health level..that should give you some info...hope this helps...

My experience with raid failing for no reason was poor cable connectivity and/or bad cables. I have a 4-drive raid 0 setup that's been running at least a year. But this was only after I replaced the SATA cables with SATA-2 ones (they have a snap-in clamp and are generally higher quality). No issues since.

Speedfan won't give you drive status on a raid 0 setup. I suggest you take each drive, or at least the "broken" one through its paces using the manufacturer's diagnostic tools, if you're still expeirencing issues after you check/replace the cables. Also, remember to power your PC properly. A momentary loss of current could render your raid 0 inactive. You can get a quality 1000W 6-rail power supply for around $170 (newegg).
