Important information about 5xxx/6xxx Floppy Fix 1.0
This document provides information about 5xxx/6xxx Floppy Fix version 1.0. This extension is being released to address two specific floppy related problems that have been reported to Apple. They are:
- Slow Floppy Diskette mounting under Mac OS 7.6, 7.6.1 or 8.0
Some floppy drives in the Power Macintosh and Performa 52xx/53xx/62xx/63xx series of computers can exhibit slow mounting when a floppy diskette is first inserted under Mac OS 7.6, 7.6.1 or 8.0. You may notice that diskettes may take up to 45 seconds for a floppy diskette to show up after being inserted into the floppy drive. The 5xxx/6xxx Floppy Fix extension corrects this problem.
-Large File Copying to Diskette Failures under Mac OS 7.6, 7.6.1 or 8.0
On some Power Macintosh and Performa 52xx/53xx/62xx/63xx series of computers, errors may occur when copying large files (>700K) to a floppy diskette. You may receive a message that says" "The file 'xxx' could not be written because a disk error occurred.ﾓ The 5xxx/6xxx Floppy Fix extension corrects this problem.
The 5xxx/6xxx Floppy Fix extension can be installed on both Mac OS 7.6.1 and Mac OS 8.0. The extension will not load on earlier system releases. The fixes included in the 5xxx/6xxx Floppy Fix extension will be included in future releases of Mac OS. If you are running under Mac OS 7.6, it is recommended that you upgrade to Mac OS 7.6.1 before installing this software. The free update is available on Apple's Software Update locations at: <http://www.info.apple.com>.

Technical Details
Slow Floppy diskette mounting under Mac OS 7.6, 7.6.1 or 8.0
Users with one of the computers mentioned above may notice that floppy diskettes can take up to 1 minute to mount after upgrading to Mac OS 7.6, 7.6.1 or 8.0. Normally, this should only take 15 - 20 seconds if the floppy diskette does not have errors. The floppy disk drive in your Power Macintosh/Performa requires a piece of software called a "driver" to interface it to the rest of the Mac OS. Mac OS 7.6, 7.6.1 and 8.0 install a new updated floppy driver for these computers. The new floppy driver, which is added to the System file in the System Folder, has an internal cache* of memory to allow for faster floppy diskette access on these computers. Unfortunately, this cache of memory is not turned on under Mac OS 7.6, 7.6.1 and 8.0 and therefore access to the floppy diskettes is slower without the 5xxx/6xxx Floppy Fix extension installed. The 5xxx/6xxx Floppy Fix extension insures that this internal cache of memory is turned on under Mac OS 7.6.1 and 8.0.
*Note: The floppy driver cache is not the same as the "Disk Cache" (controllable in the Memory Control Panel) or any processor or "Level 2" cache that may be installed. It is strictly an internal floppy driver concept.
Large File Copying to Diskette Failures under Mac OS 7.6, 7.6.1 or 8.0
Users with one of the computers mentioned above may notice that file copies of large files (>700K) to floppy diskettes may fail more often than normal under Mac OS 7.6, 7.6.1 or 8.0. This can happen even though the same diskette works fine on other computers. The updated floppy driver added to Mac OS 7.6, 7.6.1 or 8.0 could cause errors when copying large files to floppy diskettes. The 5xxx/6xxx Floppy Fix adjusts the timing of the driver to avoid this problem under Mac OS 7.6.1 and 8.0
