NTFS Partition cannot be browsed after 30 minutes of use

[BlackSlash13]

I use Ubuntu Gutsy Gibbon. I use dual boot on my SATAII Seagate 500Gb storage. Take a loot to my problem...:

I boot from Ubuntu and there, I want to browse my file from Windows XP partition. To achieve that I installed NTFS Configuration Tool via Synaptic. The result was great! I can access to my Windows folders and i have permissions of rwx (read/write/execute). But...after a couple of moments, the partition is automatically umount without reason. The whole system becomes slow. My Computer does not open. Right click on desktop not working too. WTF ?

Do you have any similar problems ?

Not a ntfs-config issue.
