ddrescue komutu

Giriş

fill-mode seçeneği

Açıklaması şöyle

When ddrescue is invoked with the option --fill-mode it operates in "fill mode", which is different from the default "rescue mode". That is, in "fill mode" ddrescue does not rescue anything. It only fills with data read from infile the blocks of outfile whose status character from mapfile coincides with one of the type characters specified in the argument to --fill-mode.

[…]

In fill mode mapfile is updated to allow resumability when interrupted or in case of a crash, but as nothing is being rescued mapfile is not destroyed. The status line is the only part of mapfile that is modified.

[…]

Example 2: Wipe only the good sectors, leaving the bad sectors alone. This way, the drive will still test bad (i.e., with unreadable sectors). This is the fastest way of wiping a failing drive, and is especially useful when sending the drive back to the manufacturer for warranty replacement.
