A system administrator has discovered a drive is malfunctioning and needs to be replaced in a server. The administrator lists properties of the exiting storage before attempting the replacement…

The parted command shown is invalid - parted requires a subcommand such as 'mkpart' and the syntax 'parted -a optimal /dev/sdb primary 0% 2000MB' is not a recognized parted command form.

Using fdisk /dev/sdb with piped echo commands allows the administrator to feed interactive keystrokes (print, delete, new, write) directly to fdisk, scripting the recreation of the partition layout documented from the original drive. This approach gives precise control over partition type, start/end sectors, and alignment when rebuilding a table from known specifications. It is a standard method for scripted partition table creation on Linux systems where sfdisk input is not available.

The mkpart subcommand belongs to parted and cannot be called as a standalone command; the device must be passed to parted itself, not appended after the size argument.

The sfdisk syntax shown ('Sfdisk -dev/sda') is malformed - the dump flag is '-d' followed by a space and the device path, and this approach also requires the source drive to still be accessible and readable.
