Effectively, there can be as many logical partitions that can be encapsulated inside an extended partition. However, Linux itself limits the total number of partitions on a drive, thus effectively there can only be 15 partitions in a SCSI disk, or 63 for IDE disks. Now I've got my documentation reconciled and corrected. Thank you people! -- Paolo Alexis Falcone [EMAIL PROTECTED] _ Philippine Linux Users Group.
