Glitchy DVDs

TOG62 wrote on 10/22/2008, 1:28 AM
Following up advice on this forum I have run tests using CD-Speed on Ritek DVD+R discs, following one or two that played poorly.

The discs were identified as Ritek F16 001. On several occasions the tests showed errors about 75% of the way through the disc. On re-testing the errors were fewer and on testing the following day they showed no errors at all. I am curious as to whether anyone else has observed anything like this or is aware of its significance.

Taiyo Yuden are great blank media.
Been using them for years with great success and NO call backs yet.

Just don't use RITEK.

I think he is wondering why he is getting different results each time he runs the test?

Yes indeed. It seems curious to me. I had already concluded that these discs are unreliable.

Isn't that the very definition of unreliable. The disks are bad and when the same disk is tested at different times, the weather, the tide, the sun and the moon and what the neighbor is wearing has an impact on the quality. Or, in short, just don't use RITEK.

A list of variables I must admit I hadn't considered ;-).

If performance had deteriorated over time I wouldn't have been at all surprised. It seemed strange to me that, on every occasion I checked, the performance had improved. It would be possible, at least in theory, to write off a brand of disc prematurely on the basis of a test carried out immediately after burning.

Anyway, thanks for the responses. It seems that no-one else has had this experience.

Actually, I went through some batches of junk disks I had lying around, and I saw the same thing. The quality of a disk would vary over time. Again, this isn't entirely surprising. Some times the drive is able to read it, at other times it is not. This is typical for low quality media, inconsistency.
