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?

For example, on a magnetic disk, ddrescue skips forward whenever it strikes an error to avoid further damage to the disk surface and/or heads which may affect the ability to recover later parts of the disk.

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?
