For what it's worth, every so often I'll make a complete backup of my data and wipe my various NAS & USB disks and then move the data back.
What I'm noticing on firmware 1.08 is some of my files are no longer usable. When Windows comes along to move the file, the source file from the NAS is no longer readable or transferable, and Explorer gives an access denied message. I can, however, *delete* said file.
Granted I'm talking about maybe 1 in every 5000 files is doing this, the rate is much higher than .. well .. zero. :) I've noticed this behavior with .mp3, .m4a, and .jpg files so far.
When I come along to another file I'll FTP into it and see if I can't get the file and see if it is usable.

I recently copied my whole 800gig DNS-323 to my DNS-321, and I had no issues reading all the files. This certainly isn't a general issue.
I'm curious why you routinely erase all the files and copy them back, what's the purpose?
-
Well I don't know the cause of it, but for some reason the file permissions are wrong. Because they're wrong, SAMBA won't move the files I've requested to move.
What I saw was:
-rwx------ 1 nobody 501 3202597 Jul 26 2008 DSC01319.JPG
Which isn't appropriate. All of the other images in the directory are -rwxrwxrwx.
So I chmod 777 DSC01319.JPG and it's accessible again.
------------------------------------
Having said that (considering my lesser understanding of SAMBA) since none of these files stored on the NAS are unix executables, shouldn't the attributes for all files coming from SAMBA be -rw-rw-rw- ?

gunrunnerjohn- It's not a routine, more like a good housekeeping practice. By going through my data it forces me to delete what's not necessary anymore and to question if I really need something. The act of reinitializing the drive means i'm starting off with a fresh filesystem, no corruption, no issues.

Probably not a bad thing, but very time consuming for all the data I have on the drive. :D
My drive is backup in any case, I sync it with my main system drives, so when stuff is maintained there, it's automatically removed from the NAS.

I was always under the impression that EXT2 actually enjoys a performance edge over EXT3. The reason for using EXT3 is the journaling that will help prevent data corruption in the event of a crash during a write.
