Hi;
When I think of disk partions, I shiverrrrrrrr. BUT, I need to make
use of disk space I know I have but need to make this safely. Please
adivse.
Following, is the result of fdisk -l:
=======================
Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 3837 30716280 83 Linux
/dev/hda3 9473 9726 2040255 82 Linux swap / Solaris
/dev/hda4 3838 9472 45263137+ 5 Extended
/dev/hda5 3838 8102 34258581 83 Linux
9729 cylinders * 8225280 bytes/cylinder = 80G
Start End partition
1 13 hda1
14 3837 hda2
3838 8102 hda5
8103 9472 (unallocated)
9473 9726 hda3
9727 9729 (unallocated)
You have a total of (9473-8103)+(9730-9727) = 1370+3 = 1373
out of 9729 cylinders allocated. So you should have 11G or
so unallocated. Perhaps I miscalculated.
You only have 4 entries in the PT, so you can't create another
partition without major effort, but you can create another
logical disc (or volume if you prefer) out of the remainder
of the extended partition (hda4). That's 1370 cylinders
(8103 through 9472 inclusive).
So (1370/9729)*80G ~ 11G. And that's all the unallocated you
can get w/o complete repartitioning. This should not be difficult.
Read the man page on fdisk.
The VERY FIRST THING you should do, is a complete backup, with
verification that it can recover your data.
Also, I'd save a copy of the MBR onto a floppy.
I'd also make me a GRUB boot floppy (or LILO, or whatever
you use) and verify that it can boot your current system.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
