Hi, everybody; I have a seven year old iBook G3 with (?) problems: it starts one out of hundred times, otherwise it displays the "unable to find the finder" sign (finder folder alternated with a ?), and yesterday it even showed me the forbidden ("broken folder") sign!! So I decided to change HD and got a TOSHIBA MK1234GAX sold to me as compatible with my iBook G3: First time I installed this new HD, I wasn't able to install MacOS X (earliest version) on it, since the HD wasn't visible to installer, so I installed the old original IBM 15GB HD back again: it started working without any explanation or excuse (maybe it just didn't want to give the job up...) Then it started again working on a 1% rate, so I took out my screwdrivers and that was enough to get it working once more! Until last time I turned the laptop off: the finder is nowhere to be found! I've tried almost everything, not even showing out screwdrivers worked; maybe it's easter pause or there might be some HD-Union sabottage strategy going on, or something... So I'm trying my brand new 120GB MK 1234GAX TOSHIBA, but it's still invisible. Help! Thanks!
