Jeg har en Maxtor DiamondMax Plus 8 30Gb HDD (6E030L0) som af en eller anden grund ikke vil auto detectes som LBA i BIOS, og ikke kører LBA af fri vilje (har dog fået den til det den er jo lavet til det)
Der er dog ét problem tilbage den kan kun overføre ca. 7Mb/s og det er jo fantastisk lidt den skulle kunne klare meget mere nok nærmere 30-40Mb/s.
Spec's på disken er:
7200 rpm, 2Mb Cache, 10-11ms og ATA133
Jeg tror problemet er at den ikke kører ATA133 men PIO-1 eller noget.
Kan ikke ændre på dette i BIOS der kan jeg kun sætte disken til:
Auto, None, Manual.
Auto, Large, LBA, CHS.
Ikke noget med DMA eller PIO modes, jeg ken ikke komme til at enable UDMA i BIOS.
Er der nogen der ved hvad jeg kan gøre ved dette?

Prøv evt at fjerne ide controlleren(primær ide controller eller sekondary ide controller) i enhedhåndtering, og lad windows automatisk installere den igen. Derefter Se om du mangler nogle opdateringer til windows.
Question
Why is my drive using PIO mode instead of DMA in Windows XP?
Answer
Problem:
The drive controller is set to use "DMA if available" but reports to be only in PIO mode. User cannot turn on DMA for ATA device. The only option for the user who wants to enable DMA mode is to uninstall and reinstall the affected channel, "Primary IDE Channel" or "Secondary IDE Channel". Reboot the system and Windows XP will reinstall the driver for the channel.
Cause:
Windows XP will turn off DMA mode for a device after encountering certain errors during data transfer operations. If more that six DMA transfer timeouts occur, Windows will turn off DMA and use only PIO mode on that device.
Windows XP downgrades the Ultra DMA transfer mode after receiving more than six CRC errors. Whenever possible, the operating system will step down one UDMA mode at a time (from UDMA mode 4 to UDMA mode 3, and so on).
All CRC and timeout errors are logged in the system event log. These types of errors could be caused by improper mounting or improper cabling (for example, 40-pin instead of 80-pin cable). Or such errors could indicate imminent hardware failure, for example, in a hard drive or chipset.

Solution:
Ensure you are using an 80-pin UDMA cable that does not exceed 18 inches in length.
Windows XP Service Pack 1.
Uninstall and reinstall the affected channel, "Primary IDE Channel" or "Secondary IDE Channel". Reboot the system and Windows XP will reinstall the driver for the channel.
Open Device Manager.
Double-click on IDE ATA/ATAPI controllers
Right-click on Primary IDE Channel or Secondary IDE Channel and select uninstall.
Click on "Ok".
Restart the system.
Upon restart, Windows will reinstall the Primary or Secondary IDE channel.
