Dear ALL,

with Regards,
Keerti

Remove then reattach drive.
Post

Code:

dmesg|tail && fdisk -l

here from the machine in question.
If not able to do such, post what you can here.

"man mount" >> "Mount options for ext2"

Nope, nothing there for specifying permissions. Which is not a surprise, since ext* is a filesystem that has the ability to store posix-style permissions and ownership data for files and directories. This is unlike FAT, for example, which doesn't and therefore needs to have simulated permissions applied to it at mount-time.

So if you want different permissions for your files, do what you do for all linux filesystems--chmod them.

As the poster above said, ext2 has its proper posix-like permissions system. You don't set/emulate permissions at mount time, they are already stored in the fs as special properties of every given file. To change the permissions of a file, directory or even the device node or the mount point you need to chmod them conveniently.

If you plan to do a massive chmod be aware that to access directories, in addition to +r you also need +x.
