Is it possible to erase data on a hard disk drive with a powerful magnet, but then be able to use the drive and the PC again?yes
Afaik, for degauss erase drive structure, you can't use it unless you have a powerful low level format tool. For the fun, I tested it with a simple electrical magnet on an open drive on 2 faulty HDD (SCSI and IDE ones). IDE one was unrecoverable, even with manufacturer userland low level format application. SCSI had been usable using SCSI adapter BIOS low level format, but had much more bad sectors than before, which tends to make me think that both degaussing and format had somehow not complete what they were supposed to do. Many papers (well, they're quite few) I read on subject all state that : . degaussing is possible, but need strong magnetic field . drive can't be reused without manufacturer intervention for a physical plates formating Other posts on the list agree theses statements. -- http://www.netexit.com/~sid/ PGP KeyID: 157E98EE FingerPrint: FA62226DA9E72FA8AECAA240008B480E157E98EE
