I'm just wondering how often you guys format your comp, cause im backing up my brothers powerbook today so im transferring all the files to my comp then back to his when i format it. I was just wondering is that bad for my powermac 2.3? i dont want to format it as i currently dont have any internal/external storage to store my files. the pb is only 60gb while i have the 250 so i cant really use the pb to backup files. I got my powermac on may 12-15th around there. I really dont want to format and have to backup everything, i know i should have a backup of my files just in case something goes wrong but im confident in my powermac that it wont die or screw for a couple of months. I do however plan on buying an external hd before school starts since i got a part time job im going to save for that and ram. Also, should i reset the pram or whatever its called on the powerbook? Also, my brother has a 1gig of ram on the powerbook but it use to show up as 1.25gb of ram now it shows up at 768ram. Is the ram bad ram cause i used the memtest program on mac to test it when it was at 1.25gb and it passed the test and i ran it more then once to be sure. But then for some reason it just changed to 768. If i open it up and reinsert it a couple of times it goes to 1.25 then it lasts a couple of days then it reverts back. Bad memory? should have been a different topic but i rahter just post in one topic. Thanks for your time.
