I have a problem with my new Plextor 740A.
Windows is showing UltraDMA mode 2, and PXInfo is showing DMA: no.
PXInfo shows also Jumper Settings: N/A ... however, the jumper is set on Cable Select. I put it also in Master without success with PXInfo (it is master on the second IDE channel).
I tried read speed test with Plextools, and the test of a movie DVD results in a media error ... at 1,32X (the test begins at 1X). Don't ask me to test with another DVDs, I have more than 100 DVDs (no copy), and I tested 10, some just bought (never played before), some older.
I tried to remove the IDE driver, rebooted ... same problem.
I tried to put the 740A on the 1st IDE channel, slave ... same problem.
I tried "/sfc scannow" to check the system files ... same problem.
I tried another IDE cable ... same problem.
I changed the power supply (now 350W) ... same problem.
I tried the DVD burner on another computer (Intel Platform) ... same problem.
I sent the burner to the repair center (RMA request, etc) ... they have no problems !!!??? ... but now I got it back, and ... guess what ... same problem as before !
I have an ASUS A7N266-C motherboard (nForce2), Athlon XP 2000+, GeForce 6600GT, 2x256Mo DDR, 2 Maxtor HDD on the first IDE channel, a CD burner (40/12/40) from Plextor and now the 740A DVD burner from Plextor too.
Please help me resolving this before I get crazy.
