By default under the Mac OS, a floppy disk is checked for problems before being mounted in the Finder. With the introduction of Mac OS 7.6.1 and in Mac OS 8, this checking is more strict to help users avoid using damaged floppies. The 5xxx/6xxx Floppy Fix 1.0 slightly improves the speed of this checking process.
The 5xxx/6xxx Floppy Fix 1.0 extension was designed to work with both Power Macintosh and Performa 5xxx/6xxx (but not the 6360) computers under both Mac OS 7.6.1 and 8. After the software was released, it was found that the 5xxx/6xxx Floppy Fix 1.0 only loads on the Power Macintosh/Performa 52xx/53xx computers. Contrary to the 5xxx/6xxx Floppy Fix Read Me, this fix does not load on the Performa 62xx/63xx computers. This has been reported to Engineering and will be corrected in the next release of the Mac OS following Mac OS 8.
In the meantime, Power Macintosh and Performa 62xx/63xx users can avoid this issue by rebuilding the desktop on the floppy disk by pressing the command and option keys when inserting the floppy. This will rebuild the desktop and decrease the amount of time it takes to mount the floppy. After inserting the floppy with the command-option keys held down, you will be asked if you want to rebuild the desktop. Click OK to start the rebuild.
