Have a raid 0....dual boot xp and vista...raid failure, get the little window that says raid disk failure...and in nvidia monitor says one of the drives is failing. Can boot to Vista, but not to xp. They are 2 hitachi 120gb. Have 6 partitions....xp, vista, programs, personal stuff (pics etc), junk (swap file) and games....just got 2 WD 160 gb want to start over. Raid 1 this time. question....are all these partitions necessary, eg...best way to set up, and....how do I tell which of HD failed....and can I do a raid 5 with 3 disks (the good hitachi).....whew!!
appreciate any help
thanks

Personally, I only do 2... System and Data. System gets the OS and all Apps. Data gets... well... data. In my case they are not partitions but physical drives but either is fine. I also recommend an additional physical drive to back up your data (external USB drives are great for this). As you just learned, drives fail.
 
You could put the three disks in RAID 5, but all drives in a RAID 5 array have to be the same capacity. It will be like having 3 120 GB drives.
 
methinks...........new raid 1...with the new drives...i'll figure out which 120 gb is bad...and use the other for storage or something.....
 
Go get the seagate seatools boot cd and let it go diagnose your hard drives. It'll tell you which drive is faulty and let you write off the bad sectors (which survives a format) however you may lose data if you do that (you get the option to not do it, it's all very clear).

However, you might wanna lose the drive that's faulty and get another replacement.
 
Seatools or whatever diagnostic software Hitachi puts out to check which one's bad. Possible neither are, the array could have failed for other reasons. 6 partitions is a hell of a lot for a personal computer, but there's no accounting for taste. Only one is "necessary," any more is strictly because you find it more convenient. Best way to set it up is most likely as individual drives, and back up anything you find important. If you're planning to use RAID 1, you get the same capacity if you only use one drive and save the other to backup anything important anyway, and it does a better job of protecting your data.

"Raid 0 Failure" is roughly equivalent to "Rain in Rainforest".
 
hitachi has a diag tool i can d/l..and i'll run it..and see which is bad....thanks for all your help

that is cute...and your right.........but i'm gonna dual boot...xp and vista
 
RAID1 doesnt offer a great backup solution, it offers less downtime. If one drive fails, the other can take its place. However, if your OS is screwed on one drive, its most likely screwed on the mirrored drive as well. If you delete a file from your main drive, its deleted from your mirrored drive, too, lol.

I usually have a couple storage drives along with my RAID0 array, and each of those storage drives have a 10GB boot partition that I can use in case my raid array fails. I also have a bunch of spare drives layin around, lol.

so your saying do a raid 0???

I'm saying have a good backup scheme if you're playin with RAID0. RAID1 isn't a good backup scheme, its good for reducing downtime, but is very costly. To reduce downtime, have a boot partition on your storage drive, which should save you a bit of money than a RAID1 array.

You thought, maybe, I was joking? Okay, yeah, joking...but the point's valid. As a general rule, RAID doesn't belong in your desktop. Marketing people like it because it gets you to buy extra hardware, and makes them look like they're adding features so you'll pay more for the same hardware. That doesn't mean it's appropriate for what you're doing.
 
buy ya gotta admit...it's an interesting discussion....
you have a point....however.....my motherboard has raid, so i'm gonna use it...stupid maybe..but..why not..I mean..isn't that why we build em....think about it...we overclock to get the slightest power out of em.....but we all know it doesn't make that much difference.....Raid 1, raid 0.....big deal..but just knowing we did it...is an accomplishment......besides i'll never use 160gb anyway......
