I would especially appreciate ideas from the experienced minds here…(not new at this myself, but here’s a stumper).
Symptom: Writing to DVD using any of Nero (6 something), NTI (6.5 something), Sonic (it came with the drive) - all yield non-verifiable results. In particular, larger files have corruption, in that they don’t match the original files on the hard drive.
Nero’s “quality” scans of the resulting disc are actually good. No PO errors, PIE and PIF within norms. Most small files write ok, anything over 300 Mbytes is hit or miss.
If I boot in safe mode (win2k), I can write without problems (other than having to boot in safe mode).
Boot normally (win2k, sp4, etc) - verification failures happen every time.
Been testing with Ridata 4x +RW’s for a few hours so I don’t waste a complete stack of +R’s. Quality scans are consistently reasonable, considering the +RW has been through 50 write sessions. Same disc records fine in safe mode, verification fails under normal boot.
Other background info: This OS and the OEM Benq 1620 have been working without flaw for at least a year. This problem appeared about 2 weeks ago.
My thinking is that it’s software / os configuration. Not sure if WMWare could have been at fault, but I removed it without behavior change.
Reset the ASPI (Adaptec 4.60).
Turned off the anti-virus (you never know…)
So far, I haven’t found “it”.
Put the BenQ into another machine - it writes without problems.
Computer is an oldie goldie M7D K7D with twin MP2600’s.
I’m about to try an alternate installation of the OS, on a fresh hard disc, to see if the problem vanishes (my thinking here is that a really need to prove a normal boot mode write works on this machine, otherwise I could be chasing RAM or some other hardware problem).
Thanks in advance for any ideas
