Right place to post scans showing disc aging?

Where’s the right place to post scans showing disc aging? The scans subforum seems focused on scans of newly written discs.


#2

Two threads right here in this forum :slight_smile:

Aging and older DVD media scans
Scans of aging and older CD media

Too bad there’s no database-driven part of the site that’d allow organized submission of such scans and precise searches. Seeking info in a single thread is difficult.


#4

I think I’ll post in that forum and maybe create sort of an index thread for my scans with links to scans on the global thread and overall statistics.

Or something. :slight_smile:

Most of the time, the comparisons are just too unreliable. :doh:

[QUOTE=shae;2102638]With enough meta-data included it could be possible to make sense of it afterwards, and possibly also update the presentation method after more “evidence” is gathered about drive behavior.[/QUOTE]Yes, it is possible: I’ve done that with my own database for my own collection, and I like to think that my analysis results are statistically sound and reliable.

Not an easy task BTW: only after about +/- 150 comparative scans + metadata were collected and cross-checked, could I start making some sense out of the mess it was… LOL :bigsmile: - now I have about 2000+ checks in this database, and I’m very confident in the information I get from the statistical cross-checks.

I’ve always been interested in an online database dedicated to media stability in real-life conditions. I’m not sure many users would agree to go through the hassle of collecting all the mandatory relevant meta-data, though.

Even without all meta-data is may still be useful.

What software do you use to keep track of all of this?

[QUOTE=shae;2103648]What software do you use to keep track of all of this?[/QUOTE]I created the relational database with an old version (3.0) of Filemaker (I like these older versions because they open up almost instantly :cool:).


#10

I’m still on the looks for cataloging software that will do what I want and be flexible enough. And I can definitely sympathize with wanting it to start quickly. :slight_smile:

v3, isn’t that from 10+ years ago?

[QUOTE=shae;2103718]v3, isn’t that from 10+ years ago?[/QUOTE]Yep LOL - I have also v5 and v8. I keep going back to V3 for speed reasons. Only thing missing in v3, for my needs, is auto-sort in external tables. I just live without it most of the time.
I rarely use v8, bloated stuff for large database administrators, no use for people like me with simple needs.
v5 is just great, fine balance between power and user-friendliness, just not fast opening enough to my taste. :stuck_out_tongue:
