SYNOPSIS

DESCRIPTION

OPTIONS

-v  Produce verbose output for each step of the checking process.

-t  Check each cluster in addition to the compressed device structure. Errors found by this option will not be repaired and may result in the clean bit being cleared, when it would have been reset without the option.

-a  automatic repair without question asked.

-r  interactive repair - ask for confirmation (not tested).

BUGS
dbck does not behave well on mounted devices. Once a compressed device/file is mounted, it behaves as a block device of size zero, which open() doesn't like. This is also a feature in a sense as You're not supposed to bypass the DouBle driver on a mounted device.
