How to get rid of error code -36 on my Mac Pro?

Can anyone tell me how to get rid of error code -36 once and for all?

I never used to get it on my old mac, but I have a year old Mac Pro running Ventura and copying files is like a 50 - 50 'will it do it'

I have done the dot_clean in terminal, I have done the fix permissions in the command I window and I still can't get rid of error code -36 when copying files to other hard drives

Anybody know of a permanent fix? It's slowing me down like crazy!

-36 is I/O error.

That sounds generic, but is actually very specific.

I/O error is generated when Bad Blocks are encountered on reading a file, but only after 1,000 re-tries using error-correction hardware.

Those disk blocks are Bad, and their original data is unrecoverable by any means. You will not be getting the files that sit in those Bad Blocks back again from that device.

The pat answer is 'restore those files from your backup copy of the files.'

...of course it is always more complex than that, and we can help you work through it, or explain better, or whatever you need help with, just ask.
