Powerbook 520 HDD help

[RWallmow]

Ok thanks for the info.. You know any good hdds to put in it? my price range is $20

Not really, all the 2.5" SCSI drives that will work in PowerBooks are going on 20+ years old now, I wouldn't really trust any of them. Those solid state options are the best solution, but you could always try your luck on eBay for vintage drives.
