Ladies and Gentlemen, I've got a 20Gb laptop harddrive in an enclosure and it won't connect to my G4 quicksilver. I think it may be because the G4 only has USB 1. However, on PCs I've never had a problem with it connecting to USB1 before. The Mac either doesn't recognise that anything is attached or a warning box comes up saying that it is unsafe or something. The harddrive is formated as FAT32. My questions are: Is it the formatting of the harddrive that is causing the problem or is it the Mac? Will upgrading to USB 2.0 PCI card solve this problem? I did try a PCI card, but it didn't work, so i returned it - what brands are Mac compatible? Who has fitted a PCI USB2.0 card to their Mac? Thanks in advance to anyone who can help me out! PS. I did try a search, but when you put in 'hard drive' you get all sorts of other stuff and these drives are called portable, external, removable... so difficult to search for. Sorry!
