According to this:

hde3

• Starts at 3642 (somethings)
• Ends at 4983 (somethings)
• Is 10,779,615 (somethings) big
• Is type "Win5" Ext'd (LBA)

and hde5:

• Starts at 3642 (somethings)
• Ends at 4983 (somethings)
• Is 10,779,583 (somethings) big
• Is type "83" regular linux

Questions[list=1][*]3642 and 4983 blocks, heads, cylinders, cumquats?[*]Same for the big numbers, e.g., 10,779,615 and 10,779,583[*]How can hde3 and hde5 start and end at the same place?[*]It seems like I ought to be able to multiply some of this stuff to arrive at the number of bytes contained in each partition. How do I do this?[/list=1]

1. Cylinders.

2. Sectors i think.

3. hda3 is an extended partition, which contains the linux system, as hda5. Windows only lets you create 1 primary partition, although you can create upto 4 (i think) primary partitions on a windows system. Win prefers to put other partitions inside an extended partition, and so fdisk will report the extended partition as well. If you look at fdisk in dos, you'll only get two partitions, the primary,. and an extended one, as dos can't see ext2 systems
