Removable Storage Drives 153 Sources for “Orphan” Drive Media, Repairs, Drivers, and Support Several removable-media drives have become “orphans” over the last few years. While the best long-term recommendation you can make is to copy all readable data off an orphan drive and transfer it to industry-standard storage devices, you might need to buy replacement drives, media, repairs, or parts to enable your clients to complete the move to new storage devices. Use Table 5.7 to help you locate these sources.

Web site: (SparQ, product www.syqt.com. EZ-Flyer, and parts others) inventory from Iomega after Iomega bought Syquest’s intellectual property in 1999. Emergency Access to Iomega Zip Drive Files in Case of Disaster Most removable-media drives are optimized for use with Windows 9x/NT/2000/Me. But in the event that the operating system fails, you want to be able to access your files, even if you must boot the machine to a command prompt. The Iomega Zip drive is the most popular removable-media drive, and files stored on the PC version can be accessed from an MS-DOS prompt using its real-mode Guest.exe driver, even if the drive was originally used with Windows 9x/NT/2000/Me. All long filenames and folder names will be displayed using their short (8+3 character) MS-DOS alias names.
