I have a Sony DVD RW DRU-720A drive on my pc. Over the past week or so, the drive has been running REALLY slow on both burning and playing media. I ran updated adaware, spybot, and antivirus programs, and cleaned up what little stuff I found, but no luck. I also uninstalled the drive, but again, no luck.
I have HJT, and could post if needed.
Thanks

Hate to seem impatient, but anyone here???
Help is REALLY needed.
Thanks.

are you using an 80 wire ide cable on it
check dma is enabled on it
check for firmware updates

djinvinceable

Hey, thanks for the response. I appologize for not completely understanding your question. Not sure what an 80 wire ide cable is, and I had my neighbor update the firmware when I bought the drive (over a year ago). The firmware is now at jyo7.
Either way, for a year now, the drive has been fine. Burning and playing media at a normal rate. About two weeks ago, the problem just up and started. It takes about two hours to rip and another two hours to back up dvds that normally only took 15 minutes to do.

check that it is in dma mode and has not dropped back to pio mode

djinvinceable

I checked out the drives properties in device manager, and I found nothing that mentioned dma or pio mode. Where can I look to fix what you suggested?

djinvinceable

Ok, I figured out how to change dma and pio mode, and here is what it looks like.
I have 2 IDE channels, one primary and one secondary.
The primary has transfer mode: dma if available in the drop down box, and ultra dma mode 5 under it. I left this one alone.
The secondary had transfer mode: PIO only in the drop down box. So I switched it to DMA if available. But the Current transfer mode mode box below it still says PIO only, and I can't change it.

back up your registry before you start and try this


go to the reg. key :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0001 or 0002 (depending on beeing primary[0001] or secondary[0002] ide channel)

there you modify the DWORD value of :
if the drive is on master: "MasterDeviceTimingModeAllowed" or
if the drive is on slave: "SlaveDeviceTimingModeAllowed"
to ffffffff

then go back to your device manager set your drive in IDE channel properties first back to pio and then, after confirming, again to dma ...that should do the trick[/b]

djinvinceable

WOW...
SO here's what I did.
I wasn't sure if the channel was primary or secondary, so I checked out 0001 and 0002. I also wasn't sure if the drive was a master or slave, so I wnet to modify the DWORD value of MasterDeviceTimingModeAllowed & SlaveDeviceTimingModeAllowed in both.

0001 had MasterDeviceTimingModeAllowed and it was already set to ffffffff
It also had SlaveDeviceType and UserMasterDeviceTimingModeAllowed and User SlaveDeviceTimingModeAllowed, but no SlaveDeviceTimingModeAllowed

0002 had neither MasterDeviceTimingModeAllowed or SlaveDeviceTimingModeAllowed but it had UserMasterDeviceTimingModeAllowed and User SlaveDeviceTimingModeAllowed. It also had MasterDeviceTimingMode
So, I really ended up changing nothing, because the only entry that matched up with exactly what you needed me to change already was at the ffffffff.
