Can Raid detect bad sector?
Posted on 2002-05-13
I am using PERC 3/SC and running RAID 1, i have the following question:
1. Can PERC 3/SC detect bad sector? If yes, what action it takes? If no, should i have to check the disk occasionally?
2. i have turned down a disk and rebuild it, but i have abort the rebuilding process and turn it ONLINE and reboot. However, during reboot, it just say it can't detect the bootable disk even i have turned the orginal disk to offline state. So is that means i can't abort the rebuilding state and put it online? But why it makes my original disk also non-bootable?
3. There must have a time gap between the rebuilding and put the disk online, so what happend if some are writing data on the disk? Can PERC 3/SC put the data on BOTH disks? OR any good suggestion?
4. PERC 3/SC provides a data checking function. But when should i use it? Use it when the disk has problem or check it occasionally?
Thanks a lot!
