Vaio PCG-K23 hard drive replacement.

I have a Vaio PCG-K23 laptop. About 5 years ago I replaced the hard drive
for two reasons. I was getting intermittent read errors and I wanted to get
a larger drive. The original drive was a Hitachi Travelstar 60GB. I replaced
it with a Samsung 160GB drive. The extra space came in handy but for some
reason, the drive would not operate in DMA mode which made it extremely
slow. It took about 10 minutes to boot. I found this website
http://winhlp.com/node/10?page=4 which pretty much explained the problem. If
you scroll down that page to the message that begins with, "For those with
the ALi M5229 IDE Controller," there is a driver that you can download,
IDE4008.exe (though now the link is dead). I installed the driver at the
time and it certainly helped. The boot time dropped to less than 4 minutes.
Still slow but not too bad. The main problem I have using this driver is
that it has disabled the hibernate option. I cannot find a way to re-enable
it. I'm guessing it has something to do with the fact that this new driver
is listed as a SCSI/RAID host controller in the device manager. Long story
short, I was wondering if using a smaller hard drive would allow me to use
the original HDD driver, restore my hibernate function, and also take
advantage of DMA mode. The larger drive will only work in PIO mode with the
original driver.

Thanks for your reply.
