Howdy Folks.

I just got a replacement for my bad Sandisk 512mb SD Card from Sandisk and so far it's worked great with TKCRom.

I'd like to try OpenZaurus again but I'm not sure if it will work on my 5500 without formatting my SD Card as ext2 which is what appears to have killed my last one.

How well does OZ work with FAT/VFAT?

Can I use a Home on SD Setup with a FAT/VFAT card?

Can I use a 40/24 Kernel and store things on my FAT/VFAT card like the 32/32 image TKCRom uses?

Thanks!

No, not really. Well you might be able to create the equivalent of a cramfs file which contains your filesystem on the fat partition but which is itself mounted, but I'm not quite sure whether that would work for jffs2 (as cramfs is read only - or am I wrong).

The answer is perhaps; with a fair bit of effort.

Is there any reason for not using ext2?

I don't know about this 32/32 image, but normally this means 32MB RAM-disk and 32MB 'RAM', so I presume so. No matter what memory layout you have you can always store and install (depending on the format) on the SD/MMC (and CF) card.

When I formatted my previous card as ext2 it started giving IO errors and corrupting its filesystem on a daily basis.

I've read that Sandisk brand work best when they are left in their native format elsewhere on the ZUG Forums.

With ext2 (which is no journalling filesystem) you have to unmount your card before removing it from your Zaurus. There should only be io errors, if you removed the card without unmounting or (totally) powered off your zaurus (without unmounting the card).
I think, that were your problems

Actually I think it also depends on which ROM you run.

I have an MMC card (Crucial 128MB) which works fine with OZ (every incarnation since 3.0), but which started throwing up the same kind of errors with pdaXrom. I never ever removed it (except to fsck and fdisk a dozen or so times in OZ once it had completely died - it still works fine, but just not with pdaXrom).
