Hello David,

Having just been given my first SSD to recover, I wondered whether
ddrescue uses any different techniques than it would use for a magnetic
disk?

Currently no.

But on an SSD, can the access mechanism be damaged by reading failing
sectors? Can the sector itself be damaged by continually trying to read it?

I don't know. So the prudent thing to do seems to leave ddrescue as-is until someone shares evidence that it should be changed.

Best regards,
Antonio.
