Hi, I have an external (USB, bus powered) hard drive formatted as UDF (using "mkudffs --media-type=hd"). There is no partitioning on the device, and I zeroed the whole thing before initialising the UDF FS.
I was writing data to it from Mac OS X when the machine ran out of batteries, leaving some apparently undeletable files. I can mount it as user-writeable with devkit (or manually), and I can delete most of the directories created by OS X. However there are some files that I cannot remove, even as root. Looking at it under my Debian Squeeze/Sid system, I see: u...@comp:User's Photos$ ls -lha ls: cannot access 2894352707_a0c8d64f03_s.jpg: Permission denied ls: cannot access 2895194764_974c6bd332.jpg: Permission denied ls: cannot access 3104930600_67e87858fb_s.jpg: Permission denied ls: cannot access 3104964654_bbdc00cdb7_s.jpg: Permission denied ls: cannot access 3104967336_eb2ee44c68_s.jpg: Permission denied ls: cannot access 3104977456_4608aa8bc3_s.jpg: Permission denied ls: cannot access 3105012298_4fa5ce6579_s.jpg: Permission denied ls: cannot access 3105365429_c03acdedd9_s.jpg: Permission denied ls: cannot access 3106207378_c9703fbdf3_s.jpg: Permission denied total 0 drwx------ 2 user user 696 2008-12-16 10:16 . drwx------ 17 user user 1.4K 2010-02-16 07:29 .. ?????????? ? ? ? ? ? 2894352707_a0c8d64f03_s.jpg ?????????? ? ? ? ? ? 2895194764_974c6bd332.jpg ?????????? ? ? ? ? ? 3104930600_67e87858fb_s.jpg ?????????? ? ? ? ? ? 3104964654_bbdc00cdb7_s.jpg ?????????? ? ? ? ? ? 3104967336_eb2ee44c68_s.jpg ?????????? ? ? ? ? ? 3104977456_4608aa8bc3_s.jpg ?????????? ? ? ? ? ? 3105012298_4fa5ce6579_s.jpg ?????????? ? ? ? ? ? 3105365429_c03acdedd9_s.jpg ?????????? ? ? ? ? ? 3106207378_c9703fbdf3_s.jpg That's a new one for me.

The data itself is safe somewhere else, but all the same I'd rather not wipe and re-format the entire drive, and if this is prone to happen it'd be good to know a better way to fix it. (Currently I'm using udftools 1.0.0b3-14 on linux 2.6.30-2-amd64.) Please CC me on any replies :) Cheers, Jason -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
