Ext2 Branch Tests

[James Tabor]

Hi all,
I tested some small files to and from root and subdirectories on the ext2 (D:)
partition w/o any errors or lockups.
Large file testing with 5147559 bytes.
copy d:\ros.zip c:\ros.zip,,, it locked up.
Only 4194304 bytes copied to drive C:. Does that number look anything familiar
to anyone? How about 400000 Hex.

Of course it does ... it's about the time when indirect blocks start to
be used instead of direct blocks...

Okay, that would make sense. So don't have indirect block support or is it just
broke?
