[qanda]This thread is about the Optiarc AD-7190A. Click here to see full specs[/qanda]hi, my name is krishnan.
i bot a dvd ram (sony / optiarc ad-7190a) abt 5 months ago.
everything was working all fine, until one day, (yesterday),, i noticed that it wasnt!!
(fyi: m using win xp sp2 OS)
history of events to back up the topic:
2 dayz ago i was trying to write a dvd (moserbaer, but most definitely duplicate) from my drive. but i was not able to. nero showed: calliberation error
sooo i googled abt it and found a solution. it said go to that IMAPI services (its mentioned below) and change the start up mode option to disabled.
i did the same, and successfully wrote those duplicate dvds (no calliberation error problems).
still ther was no prob. but when i began reading the contents from those dvds, the problem started.
ever since after i read those duplicate dvds.. when i load a cd/dvd in, and play a video/music it runs slow and un-smoothly... CPU usage reaches, sometimes, upto 100% while reading the disc.
.... same thing happens if i try to view the dvd/cd contents in Thumbnail mode (coz when it reads from the drive, processor usage shoots up and evthg goes slow)
maybe the dvd was not good. so i tried with different cds n dvds.
result: negative; all showing same results
maybe the dvd-ram drive has gone bad. so i tried it on another pc.
result: negative; the device was working perfectly fine on the other one.
maybe some nero software problem or settings problem. so i uninstalled nero 7. also, i set the start up mode option in IMAPI.sys service in Control Panel>Admin Tools>Services back to manual.
result: negative; still no solution. the same problem occurs
thus, as of this moment, i am clueless. the only thing i know is there is nothing wrong with my optiarc device. some setting that i must set/reset..!
so.. plz plz plz help me in any way possible.
hey one more thing: when i was checking the system info from nero info tool, i saw that for the optiarc dvd-ram drive, the DMA (direct memory access, i suppose) was turned OFF. hope this is of use
