Archival properties of CD-ROMs after 20 years

As part of the move from Maskachusetts to the Florida Free State, I decided to dispose of all of the CD-ROMs that were lying around in the garage and hangar. These contained backups of long-discarded PCs, 600 MB drum scans that I previously considered too large to maintain on an NAS or local drive, etc.

Despite the crummy storage conditions (temps ranging from 0 degrees to 100 degrees F and high humidity at times), only 2 out of nearly 100 CD-ROMs were problematic for reading with the $75 ASUS Blu-ray burner purchased in 2015 as part of a new PC build. (Would all of you cryptominers please let me know when you’ve stopped so that I can refresh this 6.5-year-old machine?)

Among the scans, I found this one of an early coronascientist:

Here’s a Fuji 617 slide of an oil refinery in Benicia, California:

Not bad for old tech and a single image rather than stitched-together multiples!

  1. The blog was arguably better when you were into fine art photography. There’s a limit to how far a Greenspun can go in general aviation before running out of money, but photography had unlimited growth.

    • I enjoyed when the blog was talking about ridiculously expensive speakers! It’s likely that all of the time flying planes has ruined his hearing and now he just listens to music on his iPhone!

  2. Phil, I used to know you as a very smart, rational MIT PhD alumni and as a fellow professional ATP-related pilot. Now… all you are is a bitter, mean-spirited Trump-loving middle-aged shell of your former self! Sad!! 😞

    • Hal: It is indeed a love of Donald Trump that leads most people to copy CD-ROMs onto hard drives and then use Windows File History to protect against drive failure. One of the little-known characteristics of NTFS is that Donald Trump was the inspiration for journaling (“change log”). And most people associate a garage full of CD-ROMs with being middle-aged. But I copied my CD-ROMs to the hard drive as a way of demonstrating that LOVE IS LOVE and that HATE HAS NO HOME HERE.
