You raised this same question/topic back in January (here), when you had no luck getting any response/activity from an Imation USB floppy drive connected to your G4. Because it was speculated that your G4 didn't have enough power to run the bus-powered Imation FDD, you were advised to purchase a powered USB hub, into which the FDD could be connected. To further complicate matters, you added "Some may be 400K disks but I think most are 800K DS/DD disks." Grant pointed out that only Apple's (variable-speed motor) "SuperDrive" FDD was able to read/write 800K with DS-DD floppies. This rules out the use of any USB floppy drive on the market today, because they're only compatible with 720K or 1.44 MB disks. A Sabrent floppy drive isn't going to be any more capable than the Imation that you have tried. For reading the 800K disks, you would be better off looking for a used PCI Power Mac (7300, 7500, 8500, 7600, 8600, 9500, 9600) for the purpose of transferring your files. As to what you'd transfer the files, a USB PCI card and a USB flash drive would be a solution, but the Power Mac would need to be running OS 8.6 minimally. As for reading the 400K floppies, Grant pointed out that you'd need to be running an OS version older than 8.0, which - on a PCI Power Mac - would mean 7.5x/7.6/7.6.1. The problem with that is that a USB PCI card isn't supported under OS 7.x, so the flash drive wouldn't be an option. You may want to check for any Mac User Groups in your area that might have the hardware to help you accomplish your desired goal.
