Greetings. Starting to collect info on a possible hard drive upgrade for my PB2400c. I know I need a 2.5" ATA drive, and someone suggested that I look for 5,400 RPM. I'm looking at some on newegg.com. New name brand 40GB notebook drives are running around $60-70. I don't see any distinction being made between PC and Mac, so I assume this doesn't matter (they are labeled ATA-6, is this right?). Anything I need to be attentive to otherwise for the 2400c? Any recommendations— Toshiba, Hitachi, Fujitsu, Samsung, Western Digital? Someone on powerbooks list mentioned ATA-5, so I guess there is definitely a concern that I get a drive compatible with my 'Book's ATA controller chip set. Don't know anything about it, so I thought I would post to the Duo List for some focused feedback regarding a 2400c. Thanks! Gary F. Daught gfdaught at charter.net
