st_device_modify
This job assigns new parameters to a disk. All parameters must be given.
If sector size and/or the number of sectors are different from the current ones,
the disk will be resized and (re)initialized, and all data will be lost.
If the checksum algorithm is modified, the existing checksums are reset in order
to avoid errors on READ operations.
This operation is only allowed if the disk is currently not in use.
