Make sure the FormatterOne Pro INIT Extension is in the Extensions folder and is controlling the drive. Remove any older SCSI driver extensions.
Yes, but you do need to remove the Iomega driver so that the FormatterOne Pro INIT is the extensions that is supplying the driver.
FormatterOne Pro v3.1 fully supports OS 8.5.
It takes between 5 to 10 minutes per 100 megabytes (mostly depends on the speed of the drive) a 2 gig drive will take between one and a half to three hours (or so) to format it. Of course you really seldom need to format a disk. Just "Installing" a partition on it is usually enough to make it ready for use. Most disks come pre-low level formatted from the factory and don't need to be re-low level formatted the second you take it out of the box.
Turn off file sharing. Also make sure you are not trying to format the drive you booted off of (FormatterOne Pro won't let you). Best of all, restart the machine with the extensions off, FormatterOne Pro does not need a extension to be able to format a device and this way you know that nothing will be interfering.
This means that there was already a driver preloaded at startup. Usually this means that there is either another extension that is getting control of the drive or that there is a disk in the drive and it already has its own driver. If it already has a driver written on the drive then you may want to make sure that this driver is an updated one. If the SCSI ID for that drive shows that the drive is an internal Mac drive then that is ok - your startup drive and internal Mac drives have their own drivers stored on them so that you can boot off of them.
