Hello everyone.
You guys and gals are my last hope.
One fine day my PC started responding very slow. Even menus would take
seconds before poping up. Soon I realised that it was my hard drive.
I have checked the IDE ATA/ATAPI controler and it's correctly stating that
it's using the Intel's appropriate driver which I installed myself when I
assembled the PC.
When checking the Primary and IDE channels I see that device 0 (which is my
primary HD) is set to "DMA if available" yet the current mode is "PIO Mode".
Device 1 (my DVD Drive) is also set to "DMA if available" and its current
mode is "UDMA 2".
The Secondary IDE Channels are also set to "DMA if available" and device 0
(my DVD Recorder) uses PIO Mode while device 1 (my old HD) uses "UDMA 4".
I have checked my BIOS setup and everything is set to auto and according to
its manual it should use UDMA if available.
I have bought brand new cables and I replaced the old ones but my main hard
disk is still very slow.
I have downloaded all kinds of checking utilities including those from the
HD vendor and they are reporting that both my HDs are in good working
condition.
I am getting a little dissappointed because I have tried everything I could
think off. I have even uninstalled almost everything I could, cleaned the
registry, defragmented the HDs and ran Scandisk. I have checked for viri and
malware (dialers/cookies/younameit). Nothing.
>From a vendor's site (I believe it was MS knowledge base but I honestly
dont' remember) I remember reading that if there is over a number of CRC
errors (6 I think) Windows will downgrade the HD mode. Whatever the case my
main HD is running in PIO mode when DMA is available.
Any ideas why is that? What can I do make my main HD run in UDMA mode as it
should?
Best Regards
Nick
PS
I have also checked the jumper settings (slave/master etc etc)
PS2
Are there any programs which check what transfer modes are available to a
PCs devices?
