Partition Lost

I've a Vista Business on my laptop.
I can't mount my third partition, when I try to mount it
using disk management console I got:
(I can see the partition in the list of partitions, but it can't display
file system type)
"The operation failed to complete because Disk Management Console view is
not up-to-date. Refresh the view by using the refresh task. If the problem
persists close the Disk Management console, then restart Disk Management or
restart computer."

I tried refresh and restart but I got the same error everytime.

The output of diskpart:
DISKPART> list partition

Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 OEM 6466 MB 1024 KB
Partition 2 Primary 35 GB 6467 MB
Partition 3 Primary 52 GB 41 GB

DISKPART> select partition 3

Partition 3 is now the selected partition.

DISKPART> detail partition

Partition 3
Type : 07
Hidden: No
Active: No

There is no volume associated with this partition.

I used Vista recovery DVD and I clicked on repair and then on command prompt.
Everything is fine there and my partition and files are visible!
But I can't get it to work under my Vista.

I also used paragon partition manager and tried to assign a
drive letter to my partition, but it said that the partition is
being used and it didn't work (under safe mode).


Any solutions??

I've got a similar problem. In DiskPart I get:

detail partition

Partition 0
Type : 05
Hidden : No
Active : No

There is no volume associated with this partition.

I have windows vista ultimate 32-bit. Anybody has an answer???
