Hi Pals,
I tried to change permission on a number of files and folders with chmod. the command returned no error but the mode was not changed. Does anyone know why?
pls VideoA # ls -ld Movies/
drwx------ 1 alex alex 16777216 Jul 27 11:15 Movies/
pls VideoA # chmod -v 755 Movies/
mode of 'Movies/' changed from 0700 (rwx------) to 0755 (rwxr-xr-x)
pls VideoA # ls -ld Movies/
drwx------ 1 alex alex 16777216 Jul 27 11:15 Movies/
pls VideoA # id
uid=0(root) gid=0(root) groups=0(root)
chmod doesn't work

Re: chmod doesn't work
VideoA, VideoB, VideoC are 3 volumes on a USB external disk. when I run fdisk, it shows as follows:

Partition table entries are not in disk order.
--------------------------------------------------
Another strange thing: /dev/sdb1 and /dev/sdb5 overlap. Any idea why is that? did I do something wrong?

Re: chmod doesn't work
sdb1 is an extended partition, sdb5 is just a logical partition inside of sdb1. I guess it was formatted that way to get around the limitation of MBR which only allows 4 primary partitions.
I remember reading somewhere that for FAT32 and NTFS, permissions are handled differently and must be set during mount.
