ATA 100 when it should be ATA 133?

[TBMBucket]

I have a Samsung sp0802n 80gb ata133 HD. When it boots up it only says ATA100. Why is this? I have the newest chipset drivers. Also, is system hardware it says it is in pio mode and not DMA?

What do i do?

Only Maxtor makes ATA133 drives. Its probably reporting what as it should. Don't worry about ATA133 anyways. The performance between 100 and 133 is not noticeable, not even in benchmarks.

it shouldnt be in PIO mode though, DMA should be enabled.

Im so confused

Anyway, go into your Device Manager, open the properties of the primary and secondary IDE channels, and make sure in the advanced settings "Use DMA if enabled" is selected.

I did do that use DMA if enabled and it wont work.

I even took it out and put it as a slave in all my other comps and still only PIO

So im ditching it and gettin my old 10 and 20 gigs i just tested that are dma 2 and 4

This better work.

Im startin to feel like i may be gettin somewhere.

Make sure the BIOS is set to use DMA also...

Forgot that one :beer:

By the way, i cant remember for sure, try checking the Anandtech FAQ's, but IIRC, this problem was sometimes caused by 2 problems.

1) The positioning of drives on the cable, and there jumper settings
2) Old drives not being able to work with other drives on the same channel

I cant remember for sure but i know there were people experiencing problems due to this.

You should try each drive seperatly on individual channels as masters, then add one and reboot, try different setups etc etc, then find out what could be the problem that way

What OS are you using? Also what is your motherboard?
