can't access new formatted partition.

hello
i have a 320 GB seagate hard disk
at first i installed xp on a 80 GB partition.
now that i created a logical partition of 100 GB in order to move data
to it, i can't access this partition!

in safe mode i can work on it (access, write, execute) but not in
normal mode i get: ACCESS DENIED!

here is a screen of partition permissions taken in safe mode:
