Small cosmetic DiskWarrior 3 bug
I had this huge bug with DiskWarrior 2 and Japanese file names. When it found the directory with my Japanese-named MP3 files from the FFIX soundtrack, it thought that all the Japanese-named files were named the same, and renamed them to "untitled12345", "untitled23456", and so on.
Thankfully, this is quite fixed in the new 3.0.
There's one remnant, and it's only a cosmetic bug. If the disk is named with non-ASCII Unicode characters, it doesn't show up properly in the Graph window:
Sent in as a bug.
I still do recommend DiskWarrior. It's an amazing repair utility.
