UDMA PIO Problem
Hi!
I hope someone will read the whole thing and have a suggestion what to do! Please! I've got several HDD's various manufacturers (seagate baracuda, maxtor, WD if I'm not mistaken) and all of them have 'jumped' out of UDMA into PIO just like that. Disks are from different computers, not connected in any way. Processors in those comps are from P II celeron 600Mhz up to AMD1800+. Only thing that is common is WinXP. You play games before you go to sleep, turn off the computer the usual way, turn it on the next day and it is not remotely fast as it was 'cause hdd is no longer operatin in udma mode. And the last software installed was days (weeks) ago, usually some game. In my short investigation I've learned of the several reasons that can cause that behaviour and discarded them as not being the case here. Like: not having the 80wire cable, cable not connected properly (blue connector not in the motherboard), BIOS parameters set to autodetect dma mode, WinXP ide controler not set to DMA if available etc.. I was even more confused when I got the last of those disks (master boot disk from desktop computer, winxp, 40gb baracuda 7200rpm udma5 capable etc.) and inserted it into another computer, and it automaticaly engaged the udma5 mode. Does this means that Winxp could have something to do with it? Just to mention, desktop computer of the baracuda disk doesn't have any option in BIOS regarding the udma/pio modes for ide devices. |
