Odd Disk Test Results.... should I toss this disk?

[ulTRAX]

I run a 4X Nero DVD Speed test on every backup disk I make...

But I've been getting some strange results. This last disk was max PIE = 58 and max PIF = 2.... but the disk speed, rather than stay constant, drops to zero.

This happened once before but the speed drop was not there on the second test. Same with this second disk. So do I toss the disk? Or is something wrong with the test or the drive?

Does it play ok in the DVD player? If it does, then don't toss it.

That test doesn't alway produce a will play or not play result.

"That test doesn't alway produce a will play or not play result."

that is for damn sure, i had tested a known bad disc and it said it was a-ok!
watch the discs, don't waste your time testing and playing with nero.

The read error test in DVDinfoPro is the same. Sure, it is nice to see all gree blocks in the test. I have had Memorex +RW 's have hundreds of errors in the last few hundred MB. The disc still played fine and all the files copied of the disc ok back onto the computer.

The only way to be sure is to watch the disc. I don't care what these tests come up with.

I think that different players have different levels of sensitivity to errors on discs. What looks fine on one player could show the problems on another.

I always do a CRC read error with DVDInfoPro, and any disc that has read errors (which only ever happened to me with some crappy Riteks) will be redone on another disc. I don't do any other tests than that (and watching it on my DVD player). I don't bother with any of the PI, PO and jitter testing. As long as all the sectors of the disc are readable, that's all I care about.

I know there's a big difference between my 4 year old DVD ROM drive and my new Sony DVD burner. Often Shrink has problems reading a disk on the old drive. When I run the same disk on the new drive Irarely have a problem.

I gave up on the CRCs tests when some disks I knew to play fine kept coming up with read errors. But now that I'm doing the PIE/PIF testing I'm not sure what to make of test results there.

Try running a DVD/CD cleaning disc on your old DVD-ROM. Maxell makes one that retails for approximately $10US...
