Hi,
I'm trying to learn as much as possible about the logical structures on a
hard disk. I was looking at cfdisk's printout of my partition table and I'm
a little confused by it:
---Starting--- ----Ending---- Start Number of
# Flags Head Sect Cyl ID Head Sect Cyl Sector Sectors
-- ----- ---- ---- ---- ---- ---- ---- ---- -------- ---------
1 0x80 1 1 0 0x83 239 63 1023 63 19867617
2 0x00 239 63 1023 0x05 239 63 1023 19867680 136080
3 0x00 0 0 0 0x00 0 0 0 0 0
4 0x00 0 0 0 0x00 0 0 0 0 0
5 0x00 239 63 1023 0x82 239 63 1023 63 136017
Based on the ID field, Entry #1 is the regular linux partition and entry #2
is the swap partition. My questions are:
What is Entry #2? It's ID is 05 which is an extended DOS partition.
However, when I set up my hard drive, I never created this partition. How
did it get there?
How can partition #2 and partition #5 share the same start and end h,s,c
number yet have such different start sectors (I'm assuming the 19867680 is
LBA)?
I thought partition tables could only have 4 entries. This table shows 5.
Why?
Any insight on these questions is greatly appreciated.
