2nd IDE Channel slows down the 1st

vbimport

#1

Hi everybody! I would appreciate some help with this problem that I have since I got my new computer.

Setup:

Board: Asus A7V8X
1st IDE Channel: Master HD
2st IDE Channel: Master CD-Rom (HP-8200, 24x)
Slave CD-Rom (Old 4x, panasonic?)

Whenever I have intense activity on the 2nd channel (burn/copy), it seems all the juice is taken and my HD slows down big time (even with the one I had before with this setup). Example: I’m listening to an mp3 from the HD, start to burn a CD, and BANG! the mp3 plays half the speed!

I don’t know what to look for!

Thanks.

is DMA enabled for all ur drives?


#3

How do I check that: bios or software?


#4

My HD is “Ultra DMA” and both my Cd-ROMs are in “PIO” mode.


#5

u say cd roms pio

are they burners are really just cd roms ? cause if they are burners then dma 2 is used ???


#6

One burner, one simple cd-rom


#7

if your using dma cables … 80 pin if I remember right the burner should read ultra dma 2 …and cd rom pio


#8

Updated from ASPI 4.60 to 4.71.2. It’s a little bit better (less worse!).

Bios sets burner to PIO 4 and reader to PIO 2.

I’m not using a 80-pin cable to that channel. Is it why I can’t set the burner to DMA2?


#9

yes sounds like it …if you dont then it will not use dma at all …i would change cables and try it


#10

what about your hard drive ? what is it …dma 5 ?

sorry but I repair computers for a living and trouble shoot all the time so I hvae to ask alot of question since I cant see the pc …


#11

Not sure… it’s an WD 1200-JB (8 Meg Cache). Pretty recent model in any case.

I’ll go ahead and get myself a 80-pin cable.

ya need to check and see if it is ultra dma for hard drive cause that makes big difference too

just message me to help ya more … no worries

also in bios it should all be set up to auto for finding all your devices as far as dma

what OS are u running ?


#14

I’m alright for now, thank you for helping!

My HDD is indeed running in UDMA 5 (ATA-100).
I’ll give you an update about the cd-roms when I receive the 80-pin cable I ordered.

Thx!


#15

no problem …

just let me know …will be happy to help ya and get ya going

also keep posted if that fixes ya up

IDE can only access one drive at a time. So why its using your 2nd drive it cant use the 1st drive untill the 2nd drive is stopped being used. I advise you not to put a cdrom on the same channel as a Hard drive if you are going to be using them at the same time. Maybe you can get a program that pre loads the mp3 into RAM.


#17

I am not doint that. See first message. :slight_smile:

optical drives don’t need 80-pin cables to run in DMA mode; they’re restricted to DMA mode 2 anyway. go to device manager and uninstall ur secondary ide controller, then reboot and let windows reinstall it. both drives on the controller should then be operating in DMA mode.


#19

oops i must have read it wrong :slight_smile:
So there in udma mode and have you installed IDE drivers? Like the VIA 4 in 1 or nforce drivers ? Is your HD an old one ?


#20

It is a very recent one. WD 1200-JB, 8Mb Cache.

Installing Via 4-in-1 drivers gave a slight performance amelioration.

Next step is receiving that 80-pin cable!
