Currently have 120 Seagate slave (from old system), 250 WD current master and external Iomega 250GB. Want to get rid of the old seagate, make the current master the slave and upgrade the master (looking for more speed). Can I drag and drop everything onto the iomega and then change out the internal HDs. Should make an image of all? I lost everything last time but that was because of new Mobo and other difficulties. This time only changing HDs. Thanks for the input.
