Description
When formatting a drive and changing the block size in the "Format Options" dialog, DO NOT use block sizes
other than 512 for Apple-labeled hard drives (with Apple logo sticker). Also, some SyQuest drives, mainly
5 1/4" 88 MB mechanisms, cannot be used with block sizes other than 512. Using a block size other than
512 with these mechanisms may cause drive or cartridge problems.
If you have one of these devices with early revisions of Apple firmware, our driver doesn't perform optimally
with them. If you encounter problems with these drivers, back up your data, and reinitialize your Apple-
labeled Seagate drive with Apple's HD SC setup.
SuperATM 3.5 does not perform asynchronous I/O correctly, so it does not work on the FWB JackHammer,
Quadra s, Power Macintoshes, and Macintoshes with the PowerPC upgrade card. Call Adobe for an update
AV
to 3.6 or newer.
Do not use the "Lock hard disk at startup" feature with drives on a SCSI Manager 4.3 bus. The program is not
SCSI Manager 4.3 savvy.
The HDT driver is compatible with At Ease for Workgroup's "Lock Startup Volume" security feature. However,
you need to disable At Ease's "Lock Startup Volume" security feature BEFORE updating or installing HDT
drivers.
QuickTime 1.5 causes drivers that support true background asynchronous I/O to fail under some rare
conditions. Upgrading to QuickTime 2.0 or newer fixes the problem completely. QuickTime 1.0 does not do
asynchronous I/O and is fully compatible. FWB recommends installing Apple's QuickTime 2.1 or later.
If you are unsure which versions of AppleShare and/or the Mac OS you are using, keep volume sizes on
AppleShare servers at or below 2 GB to avoid a limitation of Apple File Protocol. Volumes larger than 2 GB
will show incorrect file and folder information on remote machines unless stations have been upgraded to
System 7.5.1 or later. Testing in FWB labs has shown that networks using AppleShare version 4 or later and
System 7.5.1 or later support volume sizes on AppleShare servers up to 4 GB.
These applications erroneously report a data integrity error after decompressing files from encrypted
volumes on systems running SCSI Manager 4.3. As a workaround, decompress the file from an unencrypted
volume or just disregard the messages.
