From: torvalds@klaava.Helsinki.FI (Linus Benedict Torvalds) Subject: Extended partitions in 0.95a Date: 19 Mar 1992 16:40:23 GMT
WARNING! Linux 0.95a correctly identifies extended partitions, and seems
to set them up /partly/ right: but it also seems as if the actual new
partitions aren't correct. I don't know the exact layout of the
partition information in the extended partitions, and I just assumed it
was identical to the normal partitions. It seems I was wrong.
If your fdisk reports partitions within the extended partition, DO NOT
USE THEM! They seem to get the correct size, but not the correct
starting sector. Thus read/write to one of the extended partitions
(/dev/hdaX and /dev/hdbX , X >= 5) will access the incorrect sector, and
possibly corrupt data on one of the other partitions.
If someone could send me the data on the partition information within an
extended partition, I'd be grateful.
