Is it useful to de-fragment my Nagra Vs disk using a PC?
No, it isn’t very useful, the performance of the Nagra V will not be improved. The Nagra V can deal with fragmented files without any problems. Only extremely fragmented disks could potentially generate problems of disk access time or longer boot times. Such extreme situations will never occur on disk, which is only written on by a Nagra V, because the Nagra V takes care of this. The only benefit of a de-fragmentation is the increase in the chances of retrieving sound that was accidentally deleted.
