I have multiple 25-pack DVD-R Verbatim spindles and before burning i check the bottom of the discs for anything out of the ordinary.On many of the discs i find what looks to be like a spec of dust on the writing surface so naturally i try to clean it off, but it doesn't come off!, it's seemingly stuck in the dye.
I burn anyway and the process finishes with no problems.
Transfer rate test finishes with a smooth graph and no spikes.
I go on to the disc quality test and sometimes the test freezes before it reaches 10% so i redo the process.On the most recent disc i got a disc quality of 90, no major spikes and what seems to be a decent burn:
Drive: TSSTcorpCD/DVDW SH-S182M
Disc: DVD-R (MCC 03RG20 )
Selected speed: Maximum
PO failures: n/a
Elapsed time: 6:46
Number of samples: 129396
Average scanning interval: 1.09 ECC
Glitches removed: 0
Does this mean i shouldnt worry about the little specs?
