The external HD isn't detected

[StarAres]

I have installed F16 after I used an external 1T HD to backup the data.
F16 has a very different desktop interface, and the "Files"(Nautilus)
seems can't detect this HD because it don't appear. Its file system is ext4.

Everything is normal in F14 before the installation of F16.
What's the problem and how to solve it?

It the hard drive not mounted automatically or are you unable to mount it manually.

I formatted it to ext4 before backup. Now I can see it as a directory in /media
but I as a normal user don't have the permission to open it. Its owner and
group are "500", not my username and group.
It doesn't appear as a drive in the left drive list.

Fedora 16 changed the default starting user numbering.

F15 and earlier started them at 500, F16 changed and now they start at 1000

you need to change the user/group numbering on the files to the new numbering in F16..

su -
(root password)

chown -R --from=500:500 1000:1000 /media/directory/*

(/media/directory/* is the mountpoint for your drive change it to what it's named on your system)

Thanks. Now I can read its directory.

But why I still can't see it appear as a drive in the left drive list
for me to do something, e.g. safely remove it?

I just used "su", not "su -". Would there be some problem?

I have found it appears as a drive in the left drive list, so it's all OK now.

Many thanks for your help.
