Hidden files with rwxrwxrwx@ permission? / Drives not showing up in Finder

I have two drives, one internal and one external, that are showing up with weird permissions. The Finder refuses to display them in the sidebar or otherwise.

Victors-G5:~ VicDiesel$ cd /Volumes/
Victors-G5:Volumes VicDiesel$ ls -l
total 8
drwxrwxr-x 14 VicDiesel VicDiesel 544 Sep 18 23:05 Drobo
lrwxr-xr-x 1 root wheel 1 Sep 18 23:45 Half a Tera -> /
drwxrwxr-x@ 65 VicDiesel VicDiesel 2278 Sep 5 00:01 Sounds
drwxrwxr-x@ 20 VicDiesel VicDiesel 1292 Sep 18 10:03 iTunes Music collection
Victors-G5:Volumes VicDiesel$

Does anyone know what that at-sign signifies? Not standard Unix, afaik.

@ means an extended attribute. could be a volume icon or a finder comment or something similar. it does not affect permissions.
ls -l@

will show more info about extended attributes on the drives. they are generally nothing to worry about.

Thanks.

Any idea why those drives are not showing up in the Finder? I've copied them to a big drive, and the folders there have the same @-permission, and do also not show up in the finder. In PathFinder, they are shown, but dimmed just like dot-files.

FYI:

Victors-G5:Volumes VicDiesel$ ls -l@
total 8
drwxrwxr-x 14 VicDiesel VicDiesel 544 Sep 18 23:05 Drobo
lrwxr-xr-x 1 root wheel 1 Sep 18 23:45 Half a Tera -> /
drwxrwxr-x@ 65 VicDiesel VicDiesel 2278 Sep 5 00:01 Sounds

run

ls -laeO /Volumes

and see if any of them have hidden flags.

Yes they do.

And some googling tells me that I can clear that with "chflags".

Thanks a lot!

Victor.
