Plexwriters...no DMA?

[Mixxen]

I have a Plexwriter 8/4/32, and I was just wondering if it supports DMA transfer. Doesn't seem like this drive supports it. It's great though, no coasters yet. Maybe, if you own a different CDR brand with DMA mode, then you should turn off DMA for better reliability. Just a thought.

My 8/4/32 does in Win2k

Shoot...I'm also running win2k sp1. Here's my setup

Primary
1. Maxtor HD - "DMA if available" - Ultra DMA
2. None

Secondary
1. Plextor 8/4/32 - "DMA if available" - PIO Mode
2. Toshiba DVD - "DMA if abailbale" - DMA Mode

My bios is set to "AUTO" for PIO and Ultra DMA detection, the other option is "DISABLE". I had the same setup with my previous CDR, and it reported DMA in Device Manager....hmmmm what's going on?

Same problem here but worse:

Primary: WD 20.5 Gb HD
Use Dma if avail: Ultra DMA

Secondary:
Plexwriter 12x10x32A
Use DMA if avail: PIO Mode

Toshiba 12x DVD
Use DMA if avail: PIO Mode

wtf?

win2k here too

Primary: WD 27.3 Gb HD
Use Dma if avail: Ultra DMA

Secondary:
Philips 4x DVD
Use DMA if avail: DMA Mode

Plexwriter 8x4x32A
Use DMA if avail: DMA Mode

Strange... I am using Windows 98, and have DMA enabled for my Plexwriter 8/4/32.

sc

BTW I have the following set-up:

Primary Master: 27.3 WD HD
Primary Slave: None

Secondary Master: Plextor 8/4/32
Secondary Slave: Toshiba SD-M1402 DVD Drive

DMA is enabled for all of the above.

eeek...just upgraded to the 1.07 firmware and unistalled my plextor and still PIO mode. WTF? I'm going to uninstall the whole secondary IDE channel...and both cd drives from device manager right now.

 

[NFS4]

I'm running the 1.07 firmware

 

[Mixxen]

yeah baby!!! whoohoo... got it working.

troubledshooter: do this...
1.Uninstall both cd/dvd drives and then uninstall your secondary IDE channel from the device manager.
2.Restart and then disable the secondary IDE controler in the BIOS.
3.Boot into windows.
4.Restart again and this time enable your secondary IDE controler in the BIOS.
5.Boot into windows and it will redetect your drives.
6.Whoohoo DMA baby.
7.Disregard my 1st post.

 

[Mixxen]

Crap wait...during step 5...the drives will be redetected but defaulted to PIO Mode. Set both drives to "DMA if available", restart, then proceed to step 6.

 

[troubledshooter]

I'm on step 3, wish me luck!

 

[troubledshooter]

btw did you set a specific PIO mode in bios during step 4?

thanks

 

[troubledshooter]

NOoooooooooooooooooooooo!

Failure

thanks for the try though. Glad you got yourself working.

Nope, I just disabled the secondary IDE in bios. Booted into windows with no cd/dvd drives. Restarted and enabled secondary IDE in bios with PIO Modes set to "Auto" and Ultra DMA set to "Auto". Booted into windows again and changed the drives from PIO to DMA. Restarted and

Sorry if it didn't work...What motherboard are you using.

 

[troubledshooter]

I'm on a wholly different system, but I kinda was hoping it was just an OS/plextor problem.

BTW did you reboot between letting windows detect the drives and switching to DMA?

thanks again

Nope, I switched to DMA right after the redetection, then rebooted.

Also, I did cold reboots. A cold boot is when you shut down the computer, and wait about 3 seconds and then boot up again. A warm boot is choosing restart from the windows shut down menu. On warm boots, the bios sometimes skips stuff to boot up faster. You could try this, that's all I can think of.

The Plextor cant do udma!
its a atapi-4 device

 

[Mixxen]

We are not trying for UDMA, just DMA mode.

Why not read your manual...check bottom of page 10.
