Description says it all. I got this reading a raspbian image on a microSD card attached to USB if that helps.

We have a single filesystem driver called "ext2" that also handles ext3, and some ext4 features. It will not allow you to mount a volume if unknown ext4 features are used (see

So, DriveSetup says the filesystem driver used is "ext2". I'm not sure there is an easy way to differenciate ext3 and ext4 there?

We could rename our driver to "ext", and only advertise a "Extended File System"?

@haiqu: Since we do support ext2/3/4 this is obviously not where the problem is; thanks for looking this up, but if you'd think a bit about it, you should have known that this was just a waste of time.

The problem is that IIRC Haiku currently has no way to let the file system return a different "pretty" name for a mounted file system -- there is just one name per file system. This would have to be changed in order to support this distinction. Personally, I don't think it's worth it. Removing the "2" would help with that, as we at least wouldn't make any wrong reports.

(and yes, our ext"2" driver does check the feature bits).
