1. Before installing DiskDoubler (or any new software), we recommend making an up-to-date backup of your important files.
2. To install DiskDoubler, simply double-click the “DiskDoubler™ Installer” program. If you have a virus checking program installed, we recommend disabling it first, as it may interfere with the installation process.
3. Before using DiskDoubler you may want to run "DiskChecker™", just to make sure your disks are working correctly. The installer puts DiskChecker on your startup disk. We recommend verifying your disk with "Disk First Aid" before running DiskChecker ("Disk First Aid" comes with Apple System Software).
4. Although the DiskDoubler Installer deletes the old copies of DiskDoubler it finds in your System Folder, it does not delete old copies you may have elsewhere on your disk or on other disks. It is best to delete these old copies so that the Finder uses the new one.
5. The DiskDoubler Installer always installs "Sigma Compression INIT". If you are not using the DoubleUp™ hardware accelerator board, you can delete "Sigma Compression INIT".
If Errors Occur During Installation...
-------------------------------
1. Error -34: This indicates that your disk doesn't have enough space to install DiskDoubler. Make sure about 600K of space is free before installing.
2. Error -36: disk error. Most likely the DiskDoubler floppy disk has been damaged. Contact Salient for a replacement disk.
3. Error -48: file busy. A file could not be replaced during installation. Try installing a second time, or restarting your Macintosh (using the Restart command) and installing again. If that still doesn't work, delete all DiskDoubler files in your System Folder and then try again. Delete "DiskDoubler™ App", "DiskDoubler™ INIT", "DiskDoublerData" and "Sigma Compression INIT".
Features you don't want to miss…
--------------------------------
• Hold down the SHIFT key when pulling down the DD menu to see four new commands:
-- Compress To… for making compressed backups to another location
-- Expand To… makes an expanded copy to another location
-- Copy To… a high speed copy command
-- Create SEA… creates a self-expanding archive
• Method B (in Settings dialog). This new improved compression method compresses files smaller than ever before. It is somewhat slower than method A. We highly recommend it for telecommunications because it generates very small files.
• Background operation right from the DD menu. To allow it, check the "Can Switch To Background" option in the Settings dialog. If you are using System 6," DiskDoubler™ App" must be located in the System Folder of your startup disk for this feature to operate.
• Full System 7 compatibility, including Balloon help and color icons, support for Apple events, including compress and expand events, and 32 bit clean operation.
We hope you'll enjoy DiskDoubler. Thanks again from the team at Salient!
