Recently bought A06 DVD-Writer. It was reading CD-Rs ok first. My NERO was 5.5.10.x so it didn't support DVD writing and the Pioneer. So I decided to use the software included in the Retail Box. After installing Ulead and Nero Express both my Pioneer A06 and TDK VeloCD 32x CD Writer stopped reading my existing CD-r. It's more like Windows Explorer doesn't like them. If I check the CD-r info from Nero it shows the session, after rebooting inder DOS (w/ Win98 Start Up disk) it shows the contents. The Pioneer will only read pressed CDs, Audio CDs and DVDs...no CDrs..The TDK is even more picky I uninstalled and installed again the software, using Nero 220.127.116.11 now, played a lot w/ master/slave DMA , PIO, removing one drive than the other, updated Firmware of A06 from 1.05 to 1.06, reinstalled ASPI layer, now 4.60; removed IDE channels, so Win2k reinstalled on next reboot. The TDK doesn't have an updated firmware, or at least couldn't find one, so I just reset it to factory settings by unhooking the power cable for 15-20 min....So, that's it - no result...Otherwise A06 is working fine - burning generic Princo DVD-Rs in 4X under 14min, reading them after that ...everything is fine...but no CD-Rs....I haven't checked it yet if it burns CD-rs though..I will do thid tonight... So, any ideas are openly welcome. Txs!
