I hope someone can be of help....I recently have started having burning issues with my external HP DVD840d writer and SONY DVD+R Ver 1.3 1x-16x...I get a good burn all the way through but I get failures when in Verify mode..sometimes to the point that it hardly starts to verify and I get an error right away...other times mid-way through or towards the end.. now I know this means there is some failure in burning the disc.. but what I have managed to discover is when I play these on my standalone DVD players in my house they play fine..when I try to play it on the drive that recorded it on my pc..the thing literally wants to vibrate off the desk and then just stays in a very high speed mode and nothing...I was suspicious as to maybe it was a bad batch of SONY discs but I have had success with SONY in the past and after seeing the disc number (Disc ID: SONY-D21-00) I went back to past SONY DVDs to see if they were the same ID and sure enough they were and I had no problems burning with them.. In the past I have to juggle all types of brands mostly due to the fact of the quality becoming so bad....at the advice of message boards..I used Verbatims..which did horribly on my desktop..but worked flawlessly on my laptop...now you may ask if I have tried these SONY discs on my laptop..and I have ..and aside from a couple of bad burns they have worked fairly well..oddly though..when preparing to burn these said bad burns..I got a very high abnormal vibrating speed on my laptop which had me literally close out the burn for fear it was going to mess my drive up...any ideas?
btw: when recording on my external pc drive I have tried it @ X4, X6, X8 but have never went above that although the drive is a (16x/8x/16x/5x/8x DL).. on my laptop I am not sure at it's rate speeds but generally burns at max X4
