Hard disk upgraded

My hard disk has been almost full for sometime, and I have to copy data in and out from another external hard disk frequently. Yesterday, I finally decided to buy a new 80G one for my notebook. It is a Hitachi Travelstar with 5400 rpm and 8Mb cache. I spent 3 hours to setup everything, including back up my system, install the new hard disk and restore the system. The performance of the new hard disk seems quite good. I also reformatted my old hard disk and made an encrypted filesystem on it. I used freebsd 6's new method geli and wrote 2 scripts to mount and umount that filesystem. Now I'm quite happy with the result. I won't need to worry about the security of the data on my external hard disk any more.
