By "tooling" are you referring to the head stack assembly? If so, the 500Gb one is very likely missing some of the read/write heads that the 1Tb model will have. Also, there are a dozen other factors such as part number, DCM code, date, site, etc. which also must be considered when selecting a donor drive.
