I’ve recently bought ldw-401s drive. Overally I’m pretty happy, but today I ran into some rather inconsistent problems.
Namely, my burnt dvd+r media (tested: verbatim x2.4, verbatim x4, tdk x4) are sometimes read without any problems with “typical” curve under i.e. nero’s cdpseed, yet sometimes they get constant slowdowns/spinups or are read incredibly slowly.
Following small images (~2KB png) show situation with the same burnt dvd+r under the same conditions (only cdspeed running, most of services turned off, no additional cpu load from other processes, etc.etc.). Img nr4 was taken directly after nr3 one, with one eject/load operation inbetween. All “side” stuff (like power, cpu, ram, cooling, cabling, etc.) has been tested and seems to work well.
My question is - what can be causing this inconsitency, assuming that everything except dvd burner is ok. Some mechanical problems ? (reloading media into drive “caused” problems with reading - see 03 and 04) bad media ? (but then why are ther problems with reading only from time to time ?). Something else ?
Firmware is ES0G. Burner is alone as master drive.
TDK medias are ricoh’s. Verbatims are mitsubishi chemical corp’s (Smartburn’s identification)
Any suggestions greately appreciated.
Well, this is my first post, so btw - hello everyone
