Ultra DMA Mode 7?

Mislim da je višestruki dvobajtni DMA način rada 2 prijevod sa Multi-word DMA mode 2.

Ne znam otkad mi je to, jer sam novi HDD stavio prije dva tjedna pa nisam ni gledao koji je DMA aktivan. Zadovoljio sam se s onim što piše u HDTune.

Štoviše, ne primjećujem nikakav spori rad diska u zadnje vrijeme.

Sjetio sam se da je prva stvar koju treba napraviti deinstalacija tog ATA kanala u Device Manager-u, pa da ga on nakon restarta ponovo pronađe i dodijeli DMA Mode. Sve je to prošlo uredno, ali je i dalje DMA Mode isti - višestruki dvobajtni DMA način rada 2. Trebalo bi valjda pisati Ultra DMA način rada 6 (ili 7).

Ja ne znam što je to i trebam li se uopće obazirati na to. Ako netko zna, molim da mi kaže. Ovo je prilično zbunjujuće.

Pozdrav!

EDIT:

Evo našao sam odgovor na svoje pitanje. Možda pomogne i drugima da se ne brinu. Evo citat.

"I'm using the Asus p5b motherboard running windows7 64bit and thought I'd turn on the AHCI

in the bios rather than running my drives in IDE mode. I have two sata hard

drives and an sata dvd burner. 

I'm able to switch back and forth between modes with a registry file to

enable AHCI support and deleting the drive controllers in device manager so

they re-detect when making the change. All drives show as running in ultra

DMA5 when I do this. My problem is when I shut the machine off in AHCI

mode the next time I turn it on, device manager is showing the hard drives

running in mutl-word DMA 2 instead. IDE settings cause no such problems.

The only thing I saw that might be accurate was it's just windows mis-reporting the

DMA speed.

HD Tune shows all drives running in UDMA5 while in IDE mode

and says the drives are rated for UDMA6. In AHCI mode, HD Tune says

they're running at UDMA7 even though Windows 7 device manager says

multi-word DMA 2. 

At any rate, I did some benchmarks with both in HD Tune and the difference

was negligible. IDE mode actually gave a slightly higher read avg. but it

was so little difference it could easily change from one test to the next.

If the drives were really running in Multi-word DMA2 under AHCI, I would

have noticed a big difference."
