A couple of files appear corrupted on the SSD drive on my son's MBP, currently on macOS Catalina.
They are WAV files which refuse to play and if from a shell I run:
$ sum -r <filename>
I get "Input/output error" on the two offending files, instead of a checksum.
$ sum -r * 23188 45843 01 Bombtrack.wav 58127 58913 02 Killing In The Name.wav 40298 63213 03 Take The Power Back.wav 64550 54096 04 Settle For Nothing.wav 47065 58063 05 Bullet In The Head.wav 38280 55418 06 Know Your Enemy.wav 11798 68313 07 Wake Up.wav sum: 08 Fistful Of Steel.wav: Input/output error sum: 09 Township Rebellion.wav: Input/output error 17779 68693 10 Freedom.wav
My concern is that macOS can't find anything nothing wrong with it, and the SMART data checks out. This SSD was a replacement for the original HDD and was fitted at the apple store.
- I have run disk utility first aid on both the logical and physical volumes.
- The disk utility doesn't find anything wrong with the filesystem or underlying disk
- I'm assuming these two files sat on a corrupted part of the SSD.
In the end, Is there anything else I can do to repair or prevent corrupted parts of SSD from being used?
