Get Disk Warrior and try to boot from its CD. (I've used it; I've read too much negative about Norton Utilities to sugggest that.) Other listers may have other suggestions. Sounds like you're already thinking of removing the HD and using it as an external in an external case (or as an internal in someone else's Mac laptop) and get the data off it that way, but that'd be a last resort. The iBooks are tricky to disassemble and work on, some people just pay a company like www.wegenermedia.com to do it. The tiBooks reportedly are *much* easier to replace the HD in. For disassembly, I know of: <http://www.kodawarisan.com/ug/PowerBook/index.html>, I think "Barashi" means takeapart. <http://www.themacnut.com/> has a link to <http://homepage.usask.ca/~cjn339/overclock/>, but I just got a "page not found" from that. <http://homepage.mac.com/itiburon/cybergreg/iBook500HD.html> is for a 500MHz dual USB iceBook, and is linked various other places. <http://uk.geocities.com/ibookupgrade>, which you found.

I've talked to a friend of mine at the apple store and he tells me that if the tech feels that he needs to wipe the HD to reach a solution he will. > > i have a Ti550 and replaced it's 20GB HD w/ a 40GB (the powerbook was extremely easy to get to). I want to put 20GB HD i pulled from the powerbook into iBook and keep the current one, which i'll put into a firewire enclosure. > > i found this site (http://uk.geocities.com/ibookupgrade/), but i don't think it applies to my iBook. for one, i don't have the two screws he points to in the picture of the cd-rom bay. and two, i removed the screws he did indicate and the bottom showed no signs of wanting to come off. > > does anyone know of any site or doc that refers to this model. i'm no computer neophyte and regularly delve into the guts of systems w/ no fear; on desktops, i don't like getting into laptops w/o a doc to guide me.
