[opensuse] remove raid from hard drive
A year or so ago I experimented with raid on my pc. I don't remember the brand but I remember the card was a soft raid controller. I eventually gave up and just went to making backups. It doesn't seem to bother Windows but When I try to install SuSE, the drive is detected as a raid drive. I need to know how to remove the raid marking so the drive will be a normal drive again. Because of some other problems with the partitions, I would like to totally wipe the drive and start over (as if I just bought it). I don't know how to wipe in a way that will also remove the raid marking. Though I have tried reading about raid, I don't understand well about such things as the superblock and I don't know where this superblock is or if that is what is causing the drive to be detected as a raid drive. So far in searching this list and googling, I haven't come up with anything. Any suggestions?

Damon Register The Yast Partioner should be able to remove that or anything else, to get back to a "bare" drive.

Or you can boot the SuSE cd into rescue mode and then do a: dd if=/dev/zero of=/dev/sdX bs=4k And wait an hour or two. If you don't know the value of X above, you will need to be careful that you don't wipe the wrong disk. I typically do a "fdisk -l" to see a list of drives that linux recognizes. Then based on the size I normally know which one is which. If that does not work, I do "hdparm -I /dev/sdX" to get the S/N. and look at the paper label to verify I'm working with the drive I think I am.

Or you can simply run fdisk (or better, cfdisk) and change the partition type from FD (Linux Raid Autodetect) to 83 (Linux). This should fix it. -- =================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au =================================================== Honk if you love peace and quiet.

I could not let this pass as this statement seemed to imply that with RAID one would not need to do backups... RAID *is not* a backup solution, it is a fault tolerance solution (with some possible performance benefits). It gives the possibility of continuing a service while some hardware has failed and/or maintaining the integrity of the current state of the data in the process (e.g. for emergency backup). The line that RAID is somehow a replacement for a good backup and archive strategy is something I have heard a little too often. It can be a valuable part of such a strategy but it should *not* be relied on as the sole component, you still need to do backups, or at least regularly archive critical material (preferably both). - -- ============================================================================== I have always wished that my computer would be as easy to use as my telephone.
