Defaults to 0. interval is formatted as in the option ‘—timeout’ above. If interval begins with ‘s’, the pause is simulated and interval can be smaller than one second; the time displayed is increased by interval but without performing any pause. James was looking for a way to calculate the number of days which have passed since a certain date. Ddrescue can’t know if a bad sector is unrecoverable or if it will be eventually read after some retries. 6) Optionally write a mapfile for later use. Working almost identical to date() function only as a supplement has the time zone option.
All other block types will be considered read errors without even trying to read them from infile. Devices and partitions are accessed by means of their associated file names. The third and fourth passes read the blocks skipped due to slow areas (if any) by the first two passes, in the same direction that each block was skipped. For example, the following command line fills all blocks marked as ‘-‘ (bad-sector) with copies of the string ‘BAD SECTOR ‘: printf «BAD SECTOR » > tmpfile ddrescue —fill-mode=- tmpfile outfile mapfile Example 2: Wipe only the good sectors, leaving the bad sectors alone. Two files comparing equal with this option are equivalent when used as domain mapfiles. -q—quietQuiet operation.
Note that you must keep the original offset between ‘—input-position’ and ‘—output-position’ of the original rescue run. The first integer is the starting position of the block in the input file, the second integer is the size (in bytes) of the block. Every line in the list of data blocks describes a block of data. It contains 2 non-negative integers and a status character.
