FWB Unlock Volume 1.0 (Mac)
Source: FWB Software
Problem: After working on your hard drive with with FWB's HDT Primer, you find that the drive has become "locked" (write-protected). This prevents users from writing data to the disk. All data on the disk should remain safe and unaffected. This problem ONLY occurs on drives originally configured with Apple's Drive Setup utility (which comes with System 7.5.2). Solution: Boot from a drive other than the locked drive, then unlock the drive using Drive Setup. However, if virtual memory was on at the time of locking, neither Apple's Drive Setup software, nor FWB's software, can unlock the disk. This problem is due to changes in Apple's new driver, not supported by FWB's current version of software. If you are not able to unlock the drive with Apple's Drive Setup, run the enclosed application to unlock any volumes that have been inadvertently locked. Then install FWB's driver on the Apple Drive to eliminate the problem from occurring in the future.
