a friend of mine has either a intel 965 or 975 chipset raid 5 array with 3 250gb hdds. one of the drives has failed, is it possible to repair this? and if it is does anyone know where i can get the info to do it? i am going to attempt to do this tomorrow and im not sure how.

RAID 5 failure on intel chipset

hopefully he has a piece of software called "Intel Matrix" that will help with this, if not it is on Intel's website. from what i've seen, you pretty much replace said 250gb drive with new working one, and the software will rebuild the array for you.
disclaimer: i've never used the Matrix software to do this with RAID5, but have with RAID1 and it is good times easy.

Well, if it is Raid 5, then it should still be running with 1 failed drive although it may be slow.
You need to get into the Raid Bios and check the health of the array itself. If the Bios is reporting that one of the drives has failed, you need to isolate and replace the bad drive. During the bootup, you should see a message about hitting a key to get into the Raid Bios.
If the Bios is reporting that the array is healthy, then you simply have a hosed up Windows install, and need to work that angle.

well i replaced the bad drive with another 250 but it was seagate instead of wd. i went into the raid bios and set it to repair. all seem to be working fine, although it is a bit slow. it should be back up to full speed when the rebuild finishes? how long does that take?

It can take a few hours depending on the size of the array. If you go grab that matrix software it may be able to give you a progress report.

Doesn't the matrix software requires windows to be ran?
Or can it be ran outside of windows (i.e. in a BIOS environment)?

now im have problems with my raid0 array! im getting a error occured (0) on one of the hdds when i boot the machine. vista loads and i ran hdtune error scan and it came back with no errors. what could the problem be? it was running fine earlier today but i took my pc to work to play games and now that im back home im getting this problem. it must have happened while i was driving. dam MA roads suck!! so what should i do to further test?

I would never run RAID 5 with only 3 disks.
Why not?
Reseat all of the cables and power cords inside the machine. Well, all the ones going to the drives anyway. I have lost count of the amount of equipment I have "FIXED" with that method. A poor connection on one of the data lines could be causeing the int. problem.
Go into the Raid bios and see what kind of error it is reporting.
Last year when I was shopping for a new system, I found one ( I forget which one) boutique system builder that refused to do Raid arrays anymore because they were finding that almost half of their tech support calls were coming from the 10% of the systems they sold with Raid arrays.

Not efficient at all. RAID 5's only real advantage is that you can be "cheap" when it comes to buying disks that will used for redundancy purposes. If you're running at only 66% efficiency, 2/3 disks, then you might as well do a RAID 1 or just a plain old backup (on-site or off-site). RAID 5 is best used with 5+ disks, IMO, where the efficiency is high.
