1 Max HELL with Maxell, None Compatible on early Sony DrivesWingCommander | 04/09/2007 | See all WingCommander's reviews (48)Lets get this straight, I burn a dozen optical Discs daily, (not floppy DISK with a 'K') Only useful as Data Backup though these discs have been nothing but problems. Data read was unreliable with intermittent read errors or even verification using Nero through my Advent PC with internal Pioneer DVDRW, had to limit write 1x with 4gb limit to get reliability. Then using a JVC DVD Recorder found the discs were not replayable through any of my SONY DVD players or my SONY notebook PC. Only my Sony DVD Recorder could play them but jumped now and again!!Now also using a HP & NEC Notebook PC's and finding real problems playing the recordings done on my JVC DVD Recorder using these acursed discs. The Sony DVD Recorder couldn't record on them at all, disc error or bad disc was displayed after making wirring noises for upto 5 minutes. So frustrating, so much wasted time and money on these discs, Worst Experience!!
