Short description:
parted doesn't work for partitions created by FreeDOS's fdisk (beta7,
http://www.freedos.org):
Using /dev/sda
Error: Unable to open /dev/sda - unrecognised disk label.
Initially, FreeDOS' fdisk created 4 partitions on my 8 GB SCSI drive.
'parted' coming with SuSE Linux 7.3 wasn't able to deal with these
partitions. Thus I decided to use fdisk v2.11i coming with SuSE Linux
7.3 to remove and all logical partions plus the extended partion on
'sda2' and did let Linux occupy all available disk space. Later I
compiled parted-1.4.20 and issued the following commands.
Here's the info requested in the USER guide; if this isn't enough,
please ask for more info:
D42:~ # fdisk /dev/sda -l
Disk /dev/sda: 255 heads, 63 sectors, 1115 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 262 2104483+ 6 FAT16
/dev/sda2 263 1115 6851722+ 5 Extended

/dev/sda6 265 296 257008+ 82 Linux swap
/dev/sda7 297 1115 6578586 83 Linux
D42:~ # fdisk /dev/sda
The number of cylinders for this disk is set to 1115.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Using /dev/sda
Error: Unable to open /dev/sda - unrecognised disk label.
Information: The operating system thinks the geometry on /dev/sda is
1115/255/63. Therefore, cylinder 1024 ends at 8032.499M.
