I just purchased a samsung spinpoint f1 hd322hj (you can take a look at the drive here) for use in a 2004 iMac (specs listed here). I'm getting cold feet, though, since one reviewer over at Newegg says the following: I know that the 2004 iMac G5 is SATA1-1.5Gb/s, and usually it's not a problem to drop in a SATA II drive into an older machine. But I'm not so sure with this particular Samsung F1 model. Has anyone else had problems with this drive (or a similar problem in a 2004 G5 with a different drive)? Thanks!
