RAID Woes

Well just ordered a replacement hard drive for my dad's office. He has a RAID 1 (mirror) set set to backup the boot drive to during lunch via Norton Ghost. The mobo is an ABit IC7-G and I do plan to update all the RAID and mobo drivers before rebuilding the RAID. I am using two Maxtor DiamondMax 9 6Y080M0 (newegg) The reason I make this thread is I am wondering if there is anything that can be done to make a RAID 1 better, I don't know if the drive failed because it was a faulty drive or because of a RAID mishap, so can anyone give me some pointers or advice on how to best make RAID 1?

Well if it was a raid mishap, then both drives would have failed. But from your post, it seems like your saying only one failed, therefore it's a hard drive issue.

Err yeah. Either your explaination of the situation isn't clear or you're misunderstanding the point of a RAID 1 array.
A RAID 1 array won't magically make your disks last forever. Instead, it increases the security of your data because now you'll be able to go and get a replacement drive, put it in, rebuild the array, and the data will all still be there.
If you want one that increases uptime with data retention then you need a RAID 1 with 3 or more disks, really.

K, well that is what I was thinking. I was just wondering if you guys knew any reason why a drive would fail other then it just failed. I am hoping that the drive simply failed and the RAID will work once I put the new drive in. I didn't think the setup had any bearing on the hard drive failing, but never h urts to ask.

Its my experience that drives in RAID arrays fail more often than a drive in regular use.
Whether that's because the drive gets more use, or the raid controllers ask it to do funky things, I have no idea. So yeah, it's feasible that being part of a RAID array caused the drive to fail, but I wouldn't chalk it up to misconfiguration.
