Drive Setup can be hacked, using ResEdit, to initialize almost ANY SCSI drive. Just take a "prototype", such as any of the Seagate drives, and modify that prototype to cover the new drive. Once this has been done, the program will issue the "report drive characteristic" command, and it will, then, determine the drive capacity, etcetera, even if it differs substantially from the table entry. Usually, an ST225 is OK, but I usually modify a 2- or 4-GB Seagate, one which I KNOW was shipped with an Apple Server (WGS95, ANS 500 or ANS 700, etcetera). One NEED NOT buy FWB, which I generally consider as "mal-ware". > 4) termination is voodoo and important, a change in termination can > make all the difference. Can make ALL the difference. Most drives have a "passive" pull-up (about 2 kilohms to +5 volts), but many of the newer ones require and active pull-up (220 ohms to +5 volts and 330 ohms to ground). Note: SCSI signals are all "active low", meaning they are "asserted" when at zero to 0.5 volts and are "not asserted" when at 2.5 to 5 volts, thereby providing a rather wide "guard band". This means that if there is no source of +5 volts, even a very weak one, then no signal has a definite value. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
