New HDD formatted & XP installed old HDD stil comes up as PIO mode ?!?!

i reformatted & installed fresh XP on my ne HDD & deleted XP on my old.

so all starting from scratch.

after the install the new (boot) comes up as in UDMA Mode 5 , which is what i was after

but my old one (IDE1) is in transfer mode PIO still!!

i thought a re-formatted would put it back to UDMA Mode 5, like it was before

could my HDD be permanently damaged ??

any ideas ???
 
Have you gone into the device manager and made sure DMA is turned on for ALL your Disck controllers?
XP likes to set the seocndary to PIO mode instead of "Use DMA if available"....try it...see if it is that way.
 
yes thats all set to "use DMA if available"

its so weird!

i deleted both HDD'd & re-installed on the new one & the one is coming up as still in PIO mode

how could WinXP have a record of these?? its all been deleted

the only thing is that the old one has a partition for just games & stuff like that, personal stuff
that hasnt been deleted.

could have XP kept a setting on that part so it any XP os would set it to PIo straight away??



 
Windows XP might be getting CRC errors when communicating with the drives. If so, it will keep setting them to lower speed transfer options until the CRC errors go away. Overclocking, as well as actual drive and controller errors, could cause this, I suppose.

Still having problems daveqb? I checked VIA's website and I did not see the same IDE driver that I mentioned in my previous post. You might want to check out this link or try the performance drivers on the main driver page.

You are still getting the same problems that I had mentioned before. I was able to get my ATA66 WD drive working all the time at ATA33 by using a 40 pin IDE cable instead of a 80 pin IDE cable. When using the 40 Pin IDE cable the hard drive never reverted to a lower DMA transfer mode which I found interesting. Also, the Primary Slave drive never had this problem of lowering the DMA transfer mode as in your case. After, elminiating the possibility of a bad IDE cable (I tried different 80 pin and 40 pin cables), bad hard drive (the drive is fine in other systems), and a bad install of Windows, I was left with VIA as the source of the problem. So, I would try the drivers I listed above and hopefully they will work.
 
If you go over to Via Arena you will find plenty of instances of thgis happening with athlons and the via 4 in 1 drivers, there does not seem to be one fix but the order in which you install the various driver elements seems to make a difference.
browse the forum over there.
 
well i think i have found a solution , well maybe not a solution as such, but some reasoning;

heres a post i made on the VIZ arena forum


"well i have come to the conclusion my CRC errors are Fujitsu's fault.

i bought a new HDD (Maxtor) with the opportunity to return it if it didnt do the trick

installed XP on it & it was in UDMA mode 5

excellent, how long will it last

not long & it was in UDMA Mode
with no number to denote what transfer rate, so figured it must be 0

so naturally i thought it wasnt the HDD
but the performance hadnt slowed, nothing i could notice.

just found the Event Viewer & looked at that,
showed that there where no ATAPI errors since i installed the new HDD

then serious looked at it & the performance of my new HDD hadnt degraded at all

it was running excellant

transfered all my stuff over from the old & its been running the best its ever run,

i installed XP on it again & it was in UDMA Mode 5 again
strange?!?!

so used recovery to try & find out when it went to UDMA Mode
it was straight after the VIA install,
but with no CRC errors at the time, its not actually lowering the speed, just the speed displayed in device manager


system running the bests its ever run b4!!!


i hope this helps someone

PS the fujitsu in another system in this house has just started failing, changed MoBo's; its definately HDD
really not liking Fujitsu

Go Maxtor!!! "



i just dont understand y it displays UDMA mode when it is really running in UDMA Mode 5

anyway, the fact it is is the main thing!!

i am not sure bout this 40 & 80 pin IDE cables

how can u tell?

i make sure i use new ones, ones that come fresh with mainboards, got heaps here now



yes, benjamat, theres no stop abuse of VIA in the VIA arena

although buying a new HDD isnt the best thing for the budget, i am glad i have managed to resolve this & have a beat running system

PS there r errors in the event viewer, but still no degrading of my system , must be my old one, which i am using as a slave drive

 
those drivers on the VIA site, the miniport ones in particular crash my system , tried em a few times & system wont re-boot, have to boot in last known good state & remove em, even saf mode dont work!!!

shame, be curious to see what those IDE tools are

& i think that the 40 pin IDE has more grounding & seperation and therfore has less errors.

i read a good article on IDE cables & how they should be longer then 18 inches etc, but cont find the link , doh!
