If the unprintable docu- ment is large and very format dependent (i.e. has a large program-produced index), however, don’t break it up unless this is your last option. Instead, turn off the Background printing option on the Chooser. This will make your computer very slow during printing, but does save the formatting integrity of the document. Removable-Cartridge Errors When using Mac OS 9.x and earlier, removable-cartridge drives require a system extension to mount on the desktop while the computer is on (hot-pluggable). To see if the required removable-cartridge extension resides on your computer, open the Extensions Manager control panel and see if it’s installed. The names of the extensions are quite obvious. If the Extensions Manager doesn’t display the desired exten- sion, check in the Extensions (disabled) folder. If it’s not there, then reinstall and setup the extension. You can often access the removable cartridge drive without extension sup- port, if it’s a SCSI bus device, by simply having the cartridge inserted into the drive when you start up your computer. In Mac OS X, extensions can be verified on the Extensions tab of the System Profiler, as shown in Figure 37. FIGURE 37—Extensions Manager
Apple Computers 96 There’s a problem that the Iomega Zip drives present, called the Click of Death. The name derives from the repeated click- ing the device makes while attempting to read the Zip disk. The disk’s icon never shows up on the desktop. This problem stems from misaligned drive heads or data, usually makes the cartridge’s data inaccessible, and can potentially destroy the Zip drive. The phrase “Click of Death” is specific to Iomega Zip drives, but the same type of problem can happen to almost any other make and model of removable-cartridge drive. 1. The first part of solving the problem is to unplug the drive’s power cord. If this is a powered USB port- supported Zip drive, remove the drive’s USB cable. The sooner the power is terminated, the higher the likelihood that only the cartridge will be damaged. 2. The next step is to remove the offending cartridge. This is done by holding down the Iomega’s eject button while you plug the device back in. Keep holding the button until the cartridge pops out or you’re quite sure this action won’t net the expected results (30 seconds at the most). Failure of the eject button leaves you the option of unplugging the drive and, using a straightened-out paper clip, pushing the offending cartridge out using the eject hole located in the back of the drive. 3. The next step is to check the drive for permanent dam- age. Plug the drive power cord and connectors back in. Insert a new cartridge into the drive (one that’s in good shape and has no valuable data written on it). If the drive mounts and the icon appears on the desktop, launch the Iomega Tools program and choose the pencil eraser. This will open the Erase/Initialize Disk options window. Click on the Erase button and see if the car- tridge will reformat. If this happens, you can be pretty
