1 drive in raid 0 failed, what to do?

Hi,
I have 2x80g hdd in raid 0 and 1 of the drives failed, how do I rebuild this back up and running. I do have an image back up on another hdd. Thanks for all the help.

Hi there!

If you have adrive image of the array, the you should be able to re-image the array with it no problems, as long as your image program recognises arrays. Ghost does, as I have used it before but I could not comment on any other programs. make sure the replacement drive is as close to spec as possible also.

Hope this helps,

i used acronis true image, anyone knows if this will work. BTW, my raid 0 consist of 1 seagate and 1 hitachi, the hitachi failed and i plan to replace with a seagate. Will this be ok? how do I know if the acronis true image will recognize the new array?

RAID 0 sucks! Recovery from a drive failure is next to impossible unless you have backed up both drives with images or reserve drives.

TI will recongnize your array, but with half your data on the old Seagate and nothing on the new one - it is just about useless.

If you have a drive fail with raid 0 your pretty much screwed if you didn't backup your data. If you worried losing your data so much you should raid 1 or keep good backups.

i do have an image after the raid was setup and running. So can I then just replace the defective drive and restore the image?

 

[corkyg]

Not that easy. Striping divides all entries equally between two or more drives. The image would have to be of both drives at the same time or they won't necessarily match. Lesson learned - For reliability and security of data, avoid RAID 0. If you do have a complete two drive image, then you can restore that and be at that point in time.

If you imaged the drive after the RAID was running, you should be fine. The image program will have recognised the RAID-O stripe as single drive, so when you re-image it should organise the data over both drives.

thanks hp, that's what i wanted to know. Knowing the high risk of raid 0, i think i will restore the image to one single drive which equal the size of the raid if I can do that.

Yeah, ditch the RAID all together. You can buy a single large drive and restore to it. It does not matter if the drive is bigger than what your array was. It will just expand the partition to fill the entire drive. Well, I assume acronis does this, Ghost does.
