Linux ext2 USB stick reader/writer

Is there a Linux ext2 USB stick reader/writer for RO?

IscaFS was mentioned on another thread – it might do what you want? It’s available here

This is the bit where Colin tests it and declares that it doesn’t have any zero page problems. v0.17 is 32-bit so that’s a known.

The webpage says it also handles ext3, which would be useful for me. Has anyone tried it yet on an ARMX6 or similar?

In any case, the source is available so it should be possible to update it if required.

Hmm – That didn’t work :-(
My USB stick was 8GB – the prog uses image filing system – so what is the limit now with RO5.23 4GB?

Perhaps it could be combined with info from FAT32Fs.

Trying to change a file on the USB stick – menu.1st – saving not allowed.
Any ideas – havn’t got much help from Web – ie why do yo want to do that.

It is 4GB – RISC OS can’t deal with any single file larger than that. You can write a 4GB RO diskimage onto an 8GB stick (using !CloneDisc, for instance) but you lose 4GB of the stick’s capacity.
[Edit]: NB this is my experience with SD cards – I’ve never tried to image a memory stick, but AFAIK the 4GB single-file limit applies.

saving not allowed.

Yes, the Web page implies that the filesystem is read only.

A long time ago I wrote some software to read FileStore floppies. It just involved following the directory tree from $ and piecing the file together. Writing, on the other hand, means messing with the free space map, fragmentation, and lots of other things which must be performed flawlessly. It’s a much different proposition.

This thread reminds me that RISC OS still needs partition support.* (Does IscaFS provide its own?)

*All the functional limitations of RISC OS would be far less serious if it were possible to set up a simple multi OS boot system, without jumping through hoops.

A way around this for me – might be able to partition the end of the USB stick to say 2GB – and format partition to FAT32.

Then save info to it from Linux – transfer stick to the Iyonix and see if FAT32Fs can read it.

Still no answer on how to update file ‘menu.1st’ in the ex2 file system.

Windows7 wants to format the disk!!

[how does the duel boot ‘Ti’ manage it’s disk]
