Stacker 1.x and 2.x The FWB driver in this release is now compatible with Stacker 1.x and 2.x on systems using SCSI Manager
4.3.1 (or later), but only on the main SCSI bus (i.e., the internal bus on dual bus systems, e.g., Quadra 950,
Power Macintosh 8100, or the standard bus on other Macintoshes).

Problem/Question Potential Cause Solution
A device or volume won’t
mount to the Desktop.
The device or volume might not have
been set up to automatically mount to the
Desktop.
Try using the FWB Mounter, available from the Apple menu, to
mount the device.
If you’ve just formatted the device or created the volume, use
HDT to change the volume’s attributes so that it mounts
automatically to the Desktop.
If the device is a removable, it might not
have a driver in memory.
If the device is an IDE device, make sure the FWB IDE
extension is installed in the Extensions folder.
If the device is a SCSI device, make sure the FWB Tools
extension is installed in the Extensions folder.
On drive of greater than 1 GB capacity,
the driver partition must reside in the first
1 GB of disk space, or Macintoshes earlier
than the 840 AV cannot mount it.
Back up the data on the drive, then re-initialize the drive. Try
installing the driver again.
I can’t format a device. If you selected Quick Format, your device
might need a lower level format.
Use HDT to perform a Low Level Format.
A small file occupies too
much disk space.
Macintosh’s HFS determines the smallest
allocation unit for files (that is, minimum
file size) by the size of a volume; the
larger a volume is, the larger the
minimum size of a file will be. For
example, if the minimum file size is
500 KB, any file smaller than 500 KB will
still take 500 KB of space in a volume.
When you create a new volume, the “Smallest File Size” field
shows the minimum file size for the given volume size. To
decrease the minimum file size, reduce the expandable size of
the volume. For more information, see Creating New Volumes
in the online manual.
For information on allocation block size, see Partitioning in
the online manual.
