Archived a part of my CD collection
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.
Inventory
I have a bunch of piles:
- a spindle of disks that consists mostly of TV episodes, movies, distro and Windows images/ghosts. not imported.
- a pile of tapes and Zip drives. not imported.
- about fourty backup disks. not imported.
- about five "books" disks of various sorts. ISOs generated. partly integrated in my collection, others failed to import or were in formats that were considered non-recoverable
- a bunch of orange seeds piles
- Burn Your TV masters and copies
- apparently live and unique samples - mostly imported in
mp3 - really old stuff with tons of dupes - partly sorted through, in
jams4, reste still in the pile
- a pile of unidentified disks
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 |
