Early problem detection

PFS-2 includes code that constantly monitors its actions and checks the state of the disk.  If anything is not as it should be the disk is placed in a read only mode to protect your data.  This mode will persist until the system is rebooted or the disk is unlocked using the C:Lock command.

AFS used to place partitions in read only mode when it got confused or when the disk was corrupt.

Please ensure that no other disk activity is in progress before you reboot.

REMEMBER nothing is completely safe, which is why everyone should make regular backups, regardless of the file system that they use.
