Hmmm... haven't tried that. So it is safe to ignore the warning that fdisk generates when an active disk is being repartitioned. If I remember right, the boot sector contains descriptors for primary partitions/extended partitions, wherein these descriptors contain pertinent information (start/end CHS, partition type, boot indicator, number of cylinders and sectors). So once an fdisk operation is committed, information about the new partition layout is written to the boot sector, particularly the partition descriptors. > the only thing you need to reboot if you add another physical disk in order > for the bios to recognize it and im assuming that your hardware is not > capable of hot pluggable... > > take note also that bsd slice is limited only to 8 partitions from "a" to > "h" compare to extended partition which is unlimited until your disk space > is exhausted... Got that clear. I was under the impression that on the IA32, the total number of partitions that can encapsulate filesystems (primary and logical) is limited to 16 for IDE hard disks and 15 for SCSI hard disks (I'll check out the documentation - actually the first one I got was similar to your answer, while the second source I've got mentions the IDE/SCSI limit on the number of partitions - frankly I'm trying to sort out what to believe in and place in my final thesis documentation, as these two documents are quite conflicting). Anyway, thanks for the clarifications. -- Paolo Alexis Falcone [EMAIL PROTECTED] _ Philippine Linux Users Group.
