Am 15. Oct, 2007 schwätzte Dazed_75 so:
This machine has an 80 GB drive. It originally had M$ XP Pro on it. I then
installed a prior version of ubuntu (it has been upgraded a time or two) but
still left some unpartitioned space on the drive.. Somewhere along the line
I started playing with Linux from scratch and added a 5GB partition for it.
I just used cfdisk to look at the drive and got the following:
cfdisk 2.12r
Disk Drive: /dev/sda
Size: 80026361856 bytes, 80.0 GB
Heads: 255 Sectors per Track: 63 Cylinders: 9729
Name Flags Part Type FS Type
[Label] Size (MB)
----------------------------------------------------------------------------------------
sda1 Boot Primary NTFS
[] 31108.01
sda2 Primary Linux ext3
[/] 17116.81
sda5 Logical Linux swap /
Solaris 3002.23
sda4 Primary Linux
ext2 5000.98
Unusable 23795.74
Any idea why that last 24 GB is showing as unusable? I seem to recall that
a drive can only have 4 primary partitions but am not sure that is true.
Yeah, only 4 primary partitions on an IDE/PATA drive. I think the same
limit holds for SATA.
Even if it is, there are only 3 shown as primary. Maybe the Logical
partition counts as one of the 4 but can contain multiple "partitions"
within it?
Yeah, logical partition is a metapartition. In this case it looks like
it's not taking the whole rest of the partition.
Backup anything you want to save before mucking with the partitions.
Boot on a live CD. Delete partition sda5, recreate it to use the entire
rest of the disk and add a swap partition. mkswap on the new swap
partition and update fstab.
ciao,
