DiskLock is a security package to protect your files from unauthorized
users and accidental erasure.
It was acquired by Power On from Symantec in 1999.
Available separately: [Version 3.0][1]
Compatibility
Architecture: 68k PPC
This version supports Macintosh OS Standard disks (HFS) and Macintosh
OS Extended disks (HFS+), all versions of the Mac OS from 7.0 to
9.2.2, and Macintoshes and clones from the Macintosh SE to the latest
models (in 2000) from Apple.
DiskLock is NOT COMPATIBLE with OS X. If OS X is installed on the hard
drive, do not install DiskLock onto the drive, not even in a separate
partition. In other words, OS X and DiskLock should not both be
installed on a hard drive at the same time.
