WD AAKS + AAM - watch out

sorry ... what do you mean doesn't run under Vista 64 bit ?

you're not going anywhere near Vista

you boot from it .. ie whenpc turns on - press f8 select boot from your optical drive and voila
 
I just got a new WD5000AAKS today as it happens, and I have been scouring the net because it seems so damn slow! Is this likely to be the reason? I don't quite follow (bit of a noob here) but is this 'fix' only for RAID?

Thanks
 
no - for any mode hp01jpc

but download hdtune first - and see what your performace is

if your random access time is 13 ms or thereabouts then no need for the above

if 19ms + - then AAM is fully on = dog slow mode :)
 
Hmm thats PIO Mode (not 4 as thats 16MB).

Some guy has same issue on Planet AMD, it was a Via but same 4MB in XP64 but fine in XP32, he got the proper Drivers not MS ones and fixed it.

So are you running proper Chipset Drivers not MS ones. ?
 
The drivers for my SATA controller are Intel ones (ICH9) which I think are the correct ones no?

I think the drive might be iffy, because I am running other SATA drives from the same motherboard at drastically improved speeds. Comments?
 
Hmm Google came up with that one I posted, can you prove your in ATAPI Mode 7 or ATA 6 or UDMA 6 or whatever your Controler calls it, basically not PIO Mode.

Thanks for your help by the way. Not sure how I can prove this? Do you want a screenie of something in my device manager window? Let me know what you want and I will go and see what I can do!

Random access time isn't a problem :)

But the 4Mb/s transfer rate is :O



That can't be right!
Click to expand...

go into device manager and check the properties of all the "IDE ATA/ATAPI controllers" section-devices, on the advanced settings tab make sure its set to "DMA if available"

my 160gb AAJS seems to get "Normal" results so i think it only is on by default on 16mb cache drives

Well I cant ge that info above from my Nvidia in there, only the Silicon Image Controler, so you would need use something like Sandra SI or Everest.

I have 4 SATA HDDs connected to the motherboard. 3 of them are Seagate and all of them are fine, hitting nearly 20x the speed of the new WD one.

In device manager, I have the following:



I cannot see any entries for DMA/PIO for the 2 SATA Storage Controllers at the top. All the 6 Primary and Secondary IDE channels have DMA enabled as the transfer mode, EXCEPT the first secondary IDE channel. It is set to use 'DMA if available' but in the current transfer mode box it reads PIO mode. I googled it and tried uninstalling and reinstalling the drive, but no change.

What do ya reckon?

And yes Buckster, it is horribly slow!
