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
