• IMO, nothing much can do except waiting. Restart/turn off will only damage the disk more Disk repair is only for data retrieval, so after the repair done. Copy (don't move) your important data right away. (before even trying clone the disk). Note: also more bigger ram/memory u have will speed up the process more.
