High load during drive read/write : dmesg output, need help understanding what they are

Guys,

I'm experiencing the exact same problem and it seems to have started in
the last few weeks since dapper was released (can't pin it down any more
than that).

I have 2 x 160Gb SATA drives and, whenever anything starts using disk
reads/writes - even an apt-get install <something>, the whole system
bogs down,  screen redraws take an age and mouse goes all jerky etc.

This is a P4 3Ghz machine running the 686 kernel with SMP extensions
enabled and it has 2Gb DDR400 ram.  It should not (and was not) doing
this a little while ago.

I'd [obviously] really like to fix this and if anyone can tell me how
to check drive performance/errors/bottlenecks etc or what to look for
somewhere else, I would really appreciate it.

(output from hdparm -t -T)

/dev/sda:
Timing cached reads:   3912 MB in  2.00 seconds = 1955.88 MB/sec
Timing buffered disk reads:  106 MB in  3.19 seconds =  33.21 MB/sec

/dev/sdb:
Timing cached reads:   4008 MB in  2.00 seconds = 2003.87 MB/sec
Timing buffered disk reads:   72 MB in  3.00 seconds =  23.97 MB/sec
