I've been using RAID 0 arrays of SATA-II hard drives with Windows XP Pro successfully for some time now. Transferring Windows from a standard single disk partition to a primary partition of the RAID 0 array was trivially easy: Acronis Disk Director 10 copied the system there in a super-fast, easy step and Windows booted correctly from there as drive C (after using DD 10 to "hide" the original "C:" partition on the old system disk). No extra steps (such as described in Moving Windows to a Different Hard Disk/RAID Controller Without Reinstalling) were necessary.
But now I've built a new RAID 0 configuration of Ultra-320 SCSI disks (two identical 74 GB 15K rpm Cheetah SCSI drives) formatted as NTFS and I'm having problems copying Windows there. When I try either Acronis Disk Director 10 -or- Acronis True Image Home 11, roughly half-way through the copy/restore they both start complaining of bad sectors on the array and then they insist I choose "Ignore" or "Cancel", neither of which I want to do (obviously).
I've run CHKDSK on the SCSI RAID 0 array via an XP boot CD as well as from Windows, and it always reports there are no bad sectors. Yet I still get those bad sector warnings when I try to copy the OS there. I now know for certain that there actually are bad sectors after running a different disk scan utility. Apparently, CHKDSK found them and remapped the bad sectors, which is why it reported that no problems were found.
So now I'm stuck with not knowing how to copy Windows to the SCSI RAID array. Acronis DD 10 probably failed because it uses direct hardware transfers rather than the file system to copy the data, which is easily understandable. I figured that Acronis True Image 11 would use the NTFS file system or otherwise work around the bad sectors, but apparently that wasn't true. (By the way, I tried booting from an Acronis Disk Director 10 & True Image 11 bootable CD to perform these actions as well as running them from within Windows, but I got the same bad sector messages either way).
Note that the SCSI BIOS and the system BIOS both support booting from a SCSI RAID 0 array, and also that array has no problems writing normal data to it.
Finally, my questions:
(1): Must there be no bad physical sectors at all on a bootable RAID 0 array?
(2): Assuming that there can be bad physical sectors, how do you suggest I copy the current Windows XP Pro / SP3 installation to the SCSI RAID array without bad sector errors and also so that it will be bootable? The very last thing I want to do is re-install Windows from scratch!
Thanks.
