This drive was brand new in the box when I installed it, and I used the 15.2 installation thumb drive. I don't know why it's 1.99-2.00 and I don't know why it's different from the existing working jpo /dev/sda nor the existing broken diskfarm /dev/sda. Definitely confusing *sigh*
Is either /dev/sda or /dev/sde an old PATA disk? Did you ever use a 12.1 installation media, or some other old distro, such as Knoppix, to perform any kind of Grub repair on any installation, whether or not on that particular disk? Grub setup never gets uninstalled from a disk. It only goes away by being overwritten by something, or via a wipe. If an old installation ever used it, and nothing ever had reason to overwrite or wipe it, then there's your reason why it's there. Grub isn't always installed to the disk where the installation is that it's being set up from. Once upon a time (with various old BIOS and disk host "controllers"), an installation on /dev/sde couldn't be booted from /dev/sde anywhere (BIOS can't count to 5, or even 3), but needed to have the bootloader on a disk the BIOS could find, such as /dev/sda, to get /dev/sdeN booted. Multiboot with 4 non-RAIDed disks plus Windows is fragile. Multiply the fragility for every non-RAID disk and every RAID added beyond that. Your trouble was inevitable. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks! Felix Miata
