ddrescue:tldr:d9ddf
This command uses the ddrescue
utility with certain options to perform data recovery from one storage device to another. Here's what each part of the command means:
-
sudo
: This command runs the subsequent command with administrative privileges. It may prompt for the user's password. -
ddrescue
: It is the name of the utility used for data recovery. -
--force
: This option tellsddrescue
to overwrite the output device (/dev/sdY
) even if it contains data. Use with caution as existing data will be lost. -
--no-scrape
: This option makesddrescue
skip reading data from the source device (/dev/sdX
) when errors occur. It helps to speed up the recovery process. -
${-dev-sdX}
: It represents the path to the source device from which data will be recovered. Replace${-dev-sdX}
with the appropriate source device path such as/dev/sda
or/dev/sdb
. -
${-dev-sdY}
: It represents the path to the destination device where recovered data will be written. Replace${-dev-sdY}
with the appropriate destination device path. -
${path-to-log-txt}
: It represents the path where the log file containing recovery status will be stored. Replace${path-to-log-txt}
with the desired location and filename of the log file. For example,/path/to/log.txt
.
By executing this command, ddrescue
will start recovering data from the source device to the destination device, and it will create a log file to keep track of the recovery progress.
