Let's say that I set the block size of dd or ddrescue to 256K.
A sector of flash drives usually has 512 bytes, a sector on optical data discs has 2048 bytes.
Let's assume that in the next 256 KB, just one sector is unreadable. Every other sector is readable.
What happens to the multiblock transfer?
- Does it transfer anything at all?
- Does it transfer the readable parts as usual?
It would be great if it did transfer all readable blocks as usual.
