Though I think you may have the wrong section, your issue sounds like (unless you have changed it yourself) Windows has detected DMA errors and has fallen back to a 'safer' speed; PIO mode.
Is DMA or other options in the Device Manager window greyed out?
- check Event Viewer. There will be errors relating to disk/read errors if this is the case.
- run a disk checking tool outside of windows (Hitachi Drive Fitness Test i think is the official one from Hitachi, though you can technically use other manufacturer's ones to perform read scans)
I don't know about section(i am kinda new at forums), but windows never detected dma errors and
has not fallen back to a safer speed. It never was in dma mode.
The laptop is grant new and i installed os, but ide was never in dma mode.
-ide settings: not grayed, dma if available, but current pio
-event viewer: no disk errors
I didn't test the disk(i'll try), but i am not sure if this is the case.
Though i didn't perform full format, but quick(yes,yes, lazzzzy *******:)
Ok, i tried:
-reinstalling device drivers for intel 5 series
-disk check = ok
Fresh diagnose says disk supports udma6.
Any suggestion about this, anyone?
This is an Intel SSD forum, so I don't know why you are asking about an Hitachi mechanical drive.
Because i am a newbie .
Yes it should be at least at Graphics and chipset section.
I don't know which is producing the low disk transfer rate, the chipset(intel) or disk(hitachi).
Anyway i used hitachi ftool, but could not use it(pc-dos mode on usb key), it hangs...
Ok, thanks for replies, i'll try at hitachi forums.
