Is the "EEPROM calibration information" enough? Can you even obtain that? My understanding is that without specialized calibration equipment, transplanting platters in a multi-platter drive is a futile effort, as the platters have to be precisely aligned to replicate how they were in the original drive when the servo tracks were written. With a single platter drive, a transplant might be possible, but there may be other interplay between the calibration settings stored in the drive's EEPROM. I'm guessing that's what Nuno is referring to. Once upon a time, this trick worked. Not so much with modern drives. -Tom -- Tom Metro The Perl Shop, Newton, MA, USA "Predictable On-demand Perl Consulting." http://www.theperlshop.com/ _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
