The zeroer utility can be used to wipe empty space on a disk. In contrary to dd,
|
|
zeroer does not wipe existing files on a partition. It overwrites the
|
|
unallocated disk space around existing files, which means that deleted files
|
|
cannot be restored after processing a certain partition with zeroer.
|
|
|
|
The utility's principle consists in writing huge zero-padded memory blocks to a
|
|
file. To a certain extent this works similar to dd, however zeroer dynamically
|
|
reduces the blockwriter's buffer size when the filesystem is going to be full.
