There have been quite a few threads in several forums concerning disc deterioration over time. I have a proposal that we can discuss. Why not compile some data to record this phenomena. Have a 'results' thread where people post old scans versus new scans. This thread would be to discuss the exact parameters of this venture. Then maybe a mod or whoever can choose the proper details and thread location.
I would say some rules should be:
- must have the original scan(or scan .txt)can be any scan program
- must be able to scan in the same drive, at same speed as original scan
- must be (6 months, 9 months, 1 year) old
- can be any drive/media/burn speed/scan program as long as it is xxx old.
some problems is that scanning drives change(usually for the worse) or die, scanning programs evolve, etc. I would think that we would want to be as scientific and controlled as possible, yet be able to accumulate enough data to draw some fair conclusions. This certainly could be an ongoing thing...saving scans of today and then rescanning in a 1/2/5 years from now.
Once we create a template for submition requirements, then let the posting begin .Maybe a sub-forum could be created, with a thread for each manufacturer or MID or +R/-R or something similar, if this gets too much to handle in just one thread. I guess 'grow-as-needed' would be the best way to handle that.
unfortunately for me, I used to save all scans, but dumped them a couple months ago when cleaning up...I remember the moment.."oh, I'll never need these.." :a . My oldest currently saved scan is from March2005. I stopped saving scans in June2005(the BenQ burns were boringly consistent and great :bigsmile: ) , but i have about 250. But I did record the scan numbers with a 'sharpie' on each disc I burnt from a year ago+ up until now(part of my backup process), so I can compare personally, but that isn't very scientific.
Anyways, lets talk about it :iagree:
