The HFS File System

HFS (MAC) File System

☹
The MicroDrive Turbo Card does not allow partitions greater than 32MB, this
is the upper limit for the ProDOS File System. The only reason to open the
32MB limit would be using HFS partitions.
There are several important reasons which should keep you back from using
the HFS File System for regular hard disk usage:
 The HFS partitions does not give you any other advantages other than a larger
partition size.
 GS/OS cannot boot from a HFS partition.
 If the HFS partition becomes corrupted, there are no ways to repair the
directory structure. The partition will have to be reformatted, with a complete
loss of data.
 Writing to a HFS partition is very slow, and such, any speed advantage has
gone with using a hard disk (writing to a HFS volume is also slow when using
diskettes and other storage media).
 Using a HFS partition at read operations is not faster than using a partition
with the ProDOS File System.
Note: Due unforeseen circumstances it is recommended that you do not use the HFS
feature.
