Question Which DOS filesystem best for Mac/Linux compatibility?


Hello,

I have a flash drive that I want to use on both my Mac and my Linux PCs. Since Mac OS X can't read ext2/3 or Reiser filesystems, I guess I'll have to format the drive with a DOS filesystem (which I was trying to avoid). fdisk lists several DOS choices - which one should I use? (keeping in mind this flash drive will only be used on Macs and Linux PCs)

The choices include: FAT16, FAT16 <32M, W95 FAT32, W95 FAT32 (LBA), W95 FAT16 (LBA), W95 Ext'd (LBA), HPFS/NTFS

Which of these would be best for me, and why? Thanks.

Isn't Linux able to read/write native Mac FS?

It will only mount HFS+ read-only. I've tried several ways. See my previous post on that here:

Thanks,

Flash drives are typically formated as FAT16 from the factory. Have you reformated the drive? fdisk creates partitions, mkfs creates filesystems.

Oh, right, I knew that. When I first got the drive, I reformated with the Mac as HFS+. I quickly discovered that I could not mount under Linux, so I used fdisk to partition into two: a Linux and a DOS. Then I used mkfs to format both.

Some time later, I upgraded one of my Linux boxes from CentOS 4.0 to 4.4, then decided to try HFS+ again, so I once again reformatted with the Mac. Now it will mount under Linux, but read-only. So this time I think I'll just format the whole thing DOS.

So I guess my previous question was moot, as I was confusing partitioning and formatting. If I just use mkfs -t msdos to format, that should give me what I need. (Although, ideally, I'd rather have a 'modern' filesystem (HFS+, Reiser, ext3) that was read-write compatible on both the Mac and Linux.)

Thanks,

Joe

Now that looks promising. There is not much info on the SourceForge site. Have you used it? Is it just a matter of installing it and then the Mac will read/write an ext2 filesystem?

Thanks for the lead,

Joe

No I haven't used it, I haven't got any Mac systems. I just googled for "mac os x linux filesystems".
