Is there any way to permanently change the letter assigned to a specific partition? I have an Asus P4B533E motherboard with two hard disks, a CDROM player and a CDRW connected to the main IDE controller, so I added a new hard disk using the RAID controller (no RAID array, I just installed 1 HD). Everything works fine but the drive letters assigned to the RAID hard disk partitions are always the last two letters while the CDROM player and CDRW come first. My actual configuration looks like this: A: floppy C: primary IDE connector HD D: secondary IDE connector HD E: CDROM F: CDRW G: first RAID partition H: second RAID partition. Of course I'd like to have all the hard disks listed before the CD/CDRW devices, so I tried to change the drive letters through Computer Management/ Disk Management, but this only works for the current session, when the PC reboots everything go back to the original configuration. Do you know any way to make the drive letter settings permanent? Thanks in advance!
