Windows XP attempted upgrade:
1) clone existing 320 Gb drive onto a 500 Gb drive using Acronis
both old drive and new drive are Hitachi 5400 RPM SATA notebook drives
2) install 500 Gb into computer and reboot
3) all seems to be OK but Diskbench reveals that i/o to new drive is about a factor of 8 slower than the old drive, from 20MB/s to about 3 MB/s.
If you are use to a fast computer, then the speed reduction is mostly unbearable. CPU still is fast as indicated by superPi times that are identical before/after disk swap.
I've searched and tried about everything I can find on the net to solve the problem but to no avail.
What is wrong! I've gone back to the old 320 G drive.
