My comments were made in the context of OS/2,Windows and Linux. OS/2 will not accept primary partitions after an extended partition. I don't know if it will accept an extended inside an extended: I think it might. And it barfs on logical partitions which jump 'backwards' in the china. I don't know the situation for Linux, never having *had to* explore that. On reflection, I have learnt my lesson and always make my partitions in order... Windows does not mind 'backward' partition jumps.
Not sure you are correct that there is no good reason, but there may well be reasons which are... not great...

{^_^} Joanne, who has wanted a piece of the fdisk developer's hides
for several years now. I fondly remember the 5.0 fdisk that
was sane.

Try DFSEE (at dfess.com). This program does basically everything that fdisk, mkfs, partition magic, partinfo and partedit can do. albeit without the pretty gui. It will allow you to do *anything* that you want to the disk inluding byte editing in place. It is even available in a version on a LiveCD for recovery purposes. NOT EASY TO USE BUT POWERFUL. Not free but may be worth the money. The free demo version allows you to explore your disk and may be all you need in some cases.

My pet peeve is the games some developers play: partinfo reports your drive structure in sectors from 0 throughout but partedit requires sector numbers *relative to the beginning of the extended partition*....or the other way round... in any event, you have to keep your calculator handy.. oh joy!
