Hi everybody, did anyone of you notice the effect that the longer a DW1620 runs and warms up (open pc, cool room, cpu 44Â°C, mobo chipset 22Â°C), the worse the PI Error rate in scans get?
Example (all scans @8x of a Verbatim DVD-R 8x MCC 02RG20 written @8x):
1) Scan after PC runs couple of hours:
PI errors Maximum: 66 Average: 20.93 Total: 297916
(PC off about 2 hours)
2) Scan soon after booting:
PI errors Maximum: 41 Average: 12.29 Total: 163190
3) PC on for a while after doing scan 2):
PI errors Maximum: 71 Average: 20.41 Total: 289524
(CPU 43Â°C, Mobo 22Â°C, DW1620 feels quite hot)
4) After one scan at maximum speed, this (at 8x again):
PI errors Maximum: 76 Average: 23.24 Total: 331951
Load & Eject test with Nero CD DVD Speed
5) immediately after L&E, the next scan @8x:
PI errors Maximum: 106 Average: 21.19 Total: 300134
(first time the Average drops a little bit, but Max increases by 1/3!)
Scanning another DVD-R (written with LG GSA-4163B) at Max Speed
6) Again a scan of the DVD-R used for the other tests in this post:
PI errors Maximum: 94 Average: 21.71 Total: 310521
Like 5), so this is the error rate most probable to
Anyone any ideas? I do think it probably is a problem with the drive hardware itself - warming up seems to excerbate the PI Error rate read by the drive, while PI Failures (676, 634, 652, 651, 606, 690) stay about the same (15% deviation).
PS: I let the PC run about 45min without testing, DVD-R in drive, and do another test then. After that, I will again let the PC cool down another 45min but with the DVD-R in the drive to make sure the temperature of the DVD itself is not (or at least not much) important.
