After about three days of work, I've finished archiving a part of my old CD collection. There were about 200 CDs in a cardboard box that were gathering dust. After reading Jonathan Dowland's post about CD archival, I got (rightly) worried it would be damaged beyond rescue so I sat down and did some research on the rescue mechanisms. My notes are in rescue and I hope to turn this into a more agreeable LWN article eventually.

I post this here so I can put a note in the box with a permanent URL for future reference as well.

Remaining work

All the archives created were dumped in the ~/archive or ~/mp3 directories on curie. Data needs to be deduplicated, replicated, and archived somewhere more logical.


I have a bunch of piles:

All disks were eventually identified as trash, blanks, perfect, finished, defective, or not processed. A special needs attention stack was the "to do" pile, and would get sorted through the other piles. each pile was labeled with a sticky note and taped together summarily.

A post-it pointing to the blog post was included in the box, along with a printed version of the blog post summarizing a snapshot of this inventory.

Here is a summary of what's in the box.

Type Count Note
trash 13 non-recoverable. not detected by the Linux kernel at all and no further attempt has been made to recover them.
blanks 3 never written to, still usable
perfect 28 successfully archived, without errors
finished 4 almost perfect: but mixed-mode or multi-session
defective 21 found to have errors but not considered important enough to re-process
total 69
not processed ~100 visual estimate
