Sorry being offtopic but -

No, it is not the hardware.
If the JFS driver itself is not at fault then I suspect that the driver is exposing a problem .
Pete, I've to second the other Andreas - I am using Davids latest JFS build too on my main machine and some test machines without any problem. I've also followed your ticket and discussions about chkdsk. I've bootable JFS drives on nearly all my installations and no problems with that since years. For me it seems you're the only one having issues with JFS 1.09.06. No offend. But it seems there is something very special to -
a) your systems hardware or
b) your installations (combination of drivers, dlls ...?)
If it is a shutdown problem as mentioned above I would suggest to use the lastest xwp beta from
ftp://ftp.netlabs.org/pub/wlan/ if not already installed.
Hope you can find out the root of the problem some time.
@John - the safest way for any partitioning is using dfsee. But the "Managing partition" tool included in the latest eCS2.2beta version will work too. As suggested use a small boot volume. 1GB is enough when you install your applications and data on other partitions. But if you decide to install the rpm stuff on your boot drive too (not recommended by me but the eCS2.2beta installer) then you need a much bigger boot partition. It is possible to make a big boot partition with JFS. But probably no one will suggest this to you. Do not use big HPFS partitions (more than a few GB). There is no reason or benefit doing this these days.
