Ext2 driver causing mount to fail in linux with Ext4 formatted drive

[shaka]

I formatted a known working thumbdrive to ext4 in linux, copied some files and folders to the drive then unmounted. Mounted read/write in Haiku x64 hrev57394 and did various file operations- copied, deleted executed files etc.. Then unmounted drive.

When putting drive back in linux box it was unable to mount with a message about possible file corruption.

I have attached linux syslog output and a picture of error message

[waddlesplash]

[    0.000000] JBD2: journal checksum error
[    0.000000] EXT4-fs (sdc1): error loading journal

Well, that's not too helpful, but I guess these errors are supposed to be pretty rare.

what does e2fsck say when checking the drive?

*NOTE After running e2fsck drive worked fine in linux again

Also, is it correct that 'root' retains ownership of files/folders copied from Haiku drive to ext4 drive? If I copy the same file/folder via ftp from Haiku to Linux, the current user has ownership on the target side.
