Magnets are the rock.
So why are they not more common?
- Paranoia about debitcard wiping? (I know I'd love to have a wallet which self-closed with use of magnets.
- Paranoia about hard drives.
What I have never seen is testing of magnets on drives. Now, I have alot of nice strong rare-earth magnets, and I have some old drives which are all but ready to be decomissioned.
Testing external magnetic effects on Hard drives
- setup computer with an OS and boot drive.
- attach drive-to-test
- format drive
- write data, md5sum written data
- bring magnets to drive
- md5sum data again to check against bit corruption
- consider 'spamsum' to check for how MUCH of the data is corrupted.
- consider applying all this in a loop which runs constant, generating files (/proc/partitions), md5sum, wait for magnets, md5sum again, delete and repeat
- 10meg files?
- effects of magnets in use as files are written as well as after wrtiting is complete
Cool things to do with magnets?
- Removable/variable Car hood ornament
- wallet latch (in the futuuuure when only smartcards anyway :)
