OS4 file system support

Dear Amigans,

I am intersted in does OS 4.1. with external add ons sees the FAT16/FAT32/NTFS or EXT2 partitions?

- Can we plug FAT32 formatted usb stick and expect it to work?

- What kind of hard drive formatted partition can be used to share files between AmigaOS and PPC Linux?

Thank you for your answers

P.S.
Is CrossDOS FAT16 support still part of OS?

@vox

I have used a 32Gb USB stick with my Sam440ep which was preformated by the manufacturer with vfat I think it was. Mounted without a problem as soon as I plugged it in.

@vox

FAT16 and 32 will work out the box on OS4
NTFS and EXT2/3 won't

That is with update 2 and using USB devices directly plugged in the miggy

@vox

Besides FAT, you can read and write EXT2 with EXT2Filesystem available on aminet. Works great for my Linuxpartition I have on my SAM.
NTFS can be read, but not written to. Cannot remember how that one was called, check Aminet. Did not test it on OS4.x though. I've got it running on my OS3.9 based MediaCenter in order to read NTFS formated USB Harddrives with MP3 on it... It is a bit hard to mount it with poseidon...

@vox

You can share with Linux using FFS - mount it on the Linux side as affs.

@Chris

Quote:The Linux affs doesn't support the new AmigaOS 4.x long name formats (DOS\6 and DOS\7), and since affs has several bugs you should use a special DOS\3 ("International Fast FileSystem") partition only for that anyway, to be able to reformat it without losing important data.

ntfs doesnt work on os4. too bad as thats what i use for big files

@gerograph

Too bad the files have to be below 2 GB - otherwise they work only with Linux (or MorphOS if a Pegasos 2 system ;).

@vox

EXT2FileSystem
NTFileSystem

For using either of these filesystems on OS4 you will need this as well:
TD64Patch

@all

Be carefull. Suffering datas lost on FAT32 medias (OCZ 16gb FAT32 key).

The copy start and an error and datas lost. all datas replaced by 8+3 filename with bigger size files.

the 8+3 filename are part of a txt file on the root of the key.

Maybe related to the memguard Hit I have found, when copying datas from the HD to the FAT 32 USB key, and reported to the bugzilla AOS4.

@salass00

TD64patch isn't necessary for 4.1 (at least the current one), but for 4.0 sure.

@Thematic


For USB devices, it is, I think. At least, it was 'till AOS4.1 (not tested with update 1 or 2, though) because that 68k-Filestystem for EXT2 and NTFS need TD64 support and AOS4 is using a different approach?


I regularly use the EXT2Filesystem (not the NTFS). Unfortunately, the author has enabled a lot of debug message in his release (read the readme) which makes EXT2 on AOS4 really slow. Even coping data from a EXT2-USB-Harddisk to RAM: causes an almost full load (>80-90%) on a 1 GHz PegasosII machine.

Nevertheless, EXT2 is very handy to have ..

The problem I have with using a USB flash drive/key is corruption of the data on the stick when I delete anything on AOS4.

I can read and write to the stick, and everything remains intact, and I can transfer files to my IMac. As soon as I delete anything, the usb stick is corrupted. The system doesn't crash, so no crashlog is generated.

i have to reformat the stick and start from blank, again.

@Swoop

I can delete without problems here. the problem came during the copy (but in ramdom mode).

use memguard and try to have some output (It's easy for you for testing if problem came each delete of files).

It's possible to add them to the AOS4 bugzilla (with a short explanationn, but detailed, about the problem).
