edit. to save you reading further, what i thought was a bug, i has turned out to be hardware failure on two of my drives. no fault of imgburn whatsoever.
LONG time user, man i love this software so much!
XP sp3, burn ISO to disk. ver 2.5.6.0 , 2.5.7.0
I have two XP boxes burning ISOs to DVD from 2.5.6.0. Box one started failing with a power calibration area error, failed to write sectors 0-31. This drive has high milage so i suspected a hardware failure. So i shifted burning duty over to my secondary box, but the same error shortly appeared. with 5 and 6 year old burners, with the most up to date firmware that i can find, i chalked it up to old hardware and a coincidental simultaneous hardware failure.
Newly purchased box3 (win7 2.5.7.0) burns succesfully.
With fleeting hope that it may have been a bug or oversight, i patiently awaited a new version to try on the erroring boxes . Alas, 2.5.7.0 arrives, but the PCAError persisted. In being thorough, i located an earlier version 2.5.3.0 to try, which just this moment has finished verifying a burn on the same drive, to which 20 minutes ago, and on 2570, i only recieved the error, and could not burn.
The drives are optiarc, and sony, and write speeds were succesfully set according to both error and success log files.
In short summary, i have possibly two (one confirmed) XPsp3 boxes which cannot burn ISO using 2560 or 2570. PCAErrors persist. Version 2530 works fine.
I can certainly perform further testing on various versions if need be, or provide any more info you might need.
Anyhow, i'm very happy to find my drives are still burning fine. I've tried fresh installs with 2570, and reset the setting to no avail. that's about all i can think of to say. So thank you very much for this awesome software, and i hope my contribution is of service.
peace. Bloort.
