ok i av a quad g5 and osx 10.4.3 with internal 250gb and an external lacie 120gb(firewire400). while running techtool pros maintenance program it removed my drives from the desktop and failed to return them. according to disk utility there is something wrong with the catalog b tree and now i cannot boot from either disk. the only way to boot my system is from an edrive located on the lacie. what can i do to get my beloved drives working again?
