mounting partition and public directory

[Giuseppe Di Bona]

Hi,

I've got three problem:

1)

These are my partitions on my disk.

/dev/hdb1   *         1      1045   8393931   83  Linux
/dev/hdb2          1046      2498  11671222+  83  Linux

In the first one there is the system and in the second one i've my data.
I'm using fedora core 1 and gnome.
I'd like to mount my data partition, but i can do it only when i'm root.

How can i do that as normal user?

2)

I'd like to have a directory with data that i can share beetwen users,

what/where is the best directory i can use in the file system?

3)

When i use my flash pen disk the system try to mount it using /dev/sda1
and tell me that i need to specify the kind of file systems (it is a
vfat).

Where i can specify that the system must use /dev/sda (instead of
/dev/sda1) and the filesystem is a vfat ?


Thanks in advance,
