DVD Drive clash

Kymeia · Post by **Kymeia** » Mon Jun 11, 2007 1:29 pm

My DVD Drive freezes windows XP when I access it but only when Scope is running. When it's not it works fine but then of course I can't play audio

Must be a clash somewhere? Anyone got an idea?

Win XP sp2. P4 3.6

Well since my PC is ACPI enabled I can't control how IRQ's are set but I was able to disable devices sharing the IRQ's with my 2 Creamware cards so they currently have an IRQ each to themselves (the only conflict was with a couple of wireless networking adapters but I don't use those so they are turned off in the bios). I can't exactly see what IRQ the DVDRom is on unless its the same as the IDE bus (I guess it might be) in which case it's not the same.

As for DMA - how can I find out? It's not mentioned in the DVD's properties tab? Should it be on or off?

Just an idea - do you have ASPI installed? (you should)

I seem to have 2 primary IDE channels and 1 secondary (I do have 3 SATA harddrives as well as a DVDRW drive). The first Primary and the secondary are set to Ultra DMA but for some reason the second primary is set to PIO even though "DMA if available" is checked.

I think I do but maybe I could try reinstalling it?

Can't find the download on that page though

these kind of things I meant lately...

relax, hubird. if you use non standard stuff in a mac it won't work either.

sure, that's why

maybe you can redetect the drive in the bios, maybe a jumper setting...have you tried a different drive?

No I haven't. The drive itself works OK - it reads, it burns. But I just have to turn off Scope to avoid it freezing which means I can't open it (even to read a txt file) while Scope is running and can't play music/vids off it (no biggy that as I have 2 other PC's I can use for multimedia anyway). But it can be a pain when installing off CD so I would like to fix it.

try swapping with another drive.

exactly what is your drive config?

What do you mean? It's a DVR Writer (Sony) - came with the Pc so I'm not sure about the details of the model.

I think I just made a mistake - I went into the BIOS and loaded the default settings and now it's asking me for drivers for a RAID controller but I don't have RAID disks - they are all SATA. How can I change it back?

cable is a good guess!

to change the bios back, you'll have to find the sata section in the advanced menu in the bios and set sata to ide mode.

The DVD is IDE as far as I know.

Why do I set it to IDE mode - isn't SATA different from IDE? I thought IDE had problems with more than 2 drives?

Post by **garyb** » Wed Jun 13, 2007 2:42 pm

nope. you want sata in ide mode. your choices are ide or raid.

Kymeia · Post by **Kymeia** » Wed Jun 13, 2007 3:01 pm

Thanks. In the advanced tab there are 2 places it asks about RAId mode - one called ITE8212f controller where the options are IDE, RAID or disabled - I presume I set for IDE, and another called Silicon image Controller where the options are RAID mode, SATA mode or disabled - I presume SATA? Can't see anything else to change.

ps my mobo is an ASUS P5AD2 premium if that's any help.

Can't see anything that will make the DVDDrive DMA though.

I have disabled all the overclocking options though as the system keeps overheating (even with a huge Zalman cooler)

This is a nasty problem in XP...if it gets multiple errors on a drive it will revert to PIO (even a dirty DVD can cause this!?!)

In PIO mode your PC will grind to halt when access the drive (as you describe)

down the bottom of the page is a reg entry that will fix it (guaranteed!)

cheers

Thanks - a lot of information there. Why can't they just provide the hotfix that does it automatically? It seems to be saying you need to run the hotfix and then edit the registry but further up under "workaround" it says you should uninstall the Ide channel driver and restart windows which will reinstall it.

It also says this fix is in SP2 which I already have so I'm confused as to why this is a problem and why it should only happen when Scope is running.

I found a script to fix it but its in VB so I don't know how to run it:

yes...actually that link is the long story...the short story is this:

Run REGEDIT.
Go to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}
It has subkeys like 0000, 0001, 0002, etc. Normally 0001 is the primary IDE channel, 0002 the secondary, but other numbers can occur under certain circumstances. You have to go through these subkeys and check the DriverDesc value until you find the proper IDE channel.
Delete MasterIdDataChecksum or SlaveIdDataChecksum, depending on whether the device in question is attached as master or slave, but it can't actually hurt to delete both. Reboot. The drive DMA capabilities will be redetected.
Open Device Manager again and check whether the device is now actually using DMA mode. If so, congratulations, you've made it (at least until the next time Windows disables DMA)
