I have a t40 with the 80gb HD.  I have noticed the hard drive is very
laggy, browsing around the harddrive is not snappy.  According to
Fabbrice Bellet's page he gets about 26MB/sec out of his drive (same

I am only getting 17MB/sec.  I have set everything identical to his. 
Any suggestions?  The partition is ext3 (if that is important).
