I recorded a 40 minute program off the TV on to DVD. On playback it gets almost to the end and stops. I tried to do a copy using DVD shrink, DVD X copy and Nero copydisk. It gets to about 87 percent and I get an error. Can't read source disk.
My friend (a shopkeeper) has just told me that his contacts in the secondhand market always use windolene to clean unplayable CDs/DVDs.
Is that a feasible option. I always thought windolene was an abrasive?
If you do attepmt any cleaning/repair, remember that DVDs and CDs read from the centre to the periphery so if there is any physical fault towards the end of play, the edge of the disk is the place to look for it.
I'm surprised that your writer allowed the disk to be burned. Many writers do a preliminary check.
As FE says, though, it may be a faulty disk. I've burned many hundreds of DVDs and had two faulty ones. The fault in each case was different but obvious on examination.
When you clean CDs or DVDs, do not rub them with a circular motion - rub across the disk. Any scratches that are made are likely to be more easily dealt with by te error correction, as they will shorter.
I have used T-Cut to remove scratches from unreadable discs,I had ten DVD-RW discs that slowly developed more troubles with read/write operations.A few hours of polishing the discs enabled me to recover the data from them and burn to new discs,and some are still usable afterwards.I opted to try this solution as a "kill or cure" The discs were already unreadable,all I would ultimately have done is waste a few drops of T-Cut.
I have seen many CDs being sold at car boot sales that I would have confined to the dustbin.
Also, just as with vinyl recordings, one should not touch the recorded area. This picks up grease and grime which may cause the laser reader to misread the data on the CD. Finally, they should not be subjected to excessive heat.
