Multiple hard drives, unrecognized drives, unexpected change of boot priority.
My C: partition is one of three partitions on a RAID 0 array that
consists two 250G HDDs. I have two other 250G HDDs running individually. When I replace HDD number 3 with a new (unformatted) 1TB HDD the three partitions on the other individual HDD disappears from Explorer and the 1TB drive does not show either. Drive 1 (two physical drives in array), C:, E:, and G: Drive 2: D:, F:, H:. Drive 3: I: CD/CDV: Z: Two other unusual events might be a clue to this problem: Clue 1) I enlarged the partition on drive 3 to 250G with Partition Magic v8. When I rebooted, PM had caused a change in boot order. Had to use DEL to enter BIOS to correct the boot order so drive 1 is first. This has happened before with PM. When booting properly the boot priorities a SCSI-2 - 7Li_RAID SCSI-1 - ST3250823AS SCSI-0 - ST3250823AS Bootable Add-in Cards When the boot order is messed the RAID is on the third line. Elsewhere in BIOS is: First Boot Device: Floppy Second Boot Device: CDROM Third Boot Device: Hard Disk Clue 2) During every normal boot-up the last text statement on the screen prior to the windows startup screen is "Boot from CD". Q1 - why can't I see the 1TB HDD and why does HDD #2 disappear from Explorer when it is connected? Q2 - Why would the boot order get messed when I reboot after using Partition Magic to resize the partition I on drive 3? Q3 - why would the boot-up screen say "Boot from CD"? Advice will be appreciated, Stan Hilliard System: Windows XP SP2, home built computer, all drives are SATA, the 250G drives are Maxtor, the 1TB drive is Western Digital. |
