GD's data tracks, as CD's, have some kind of checksum to prevent wrong read. So if some sector doesn't match with the checksum, the reader reads it again, and again, until reads it right.

When dumping a GD on DreamShell, is this redundancy info checked? I mean, if some read is corrupted, it tries to read again? Or there is a (significant) chance of reading corrupted data?

I believe this kind of verification is at the hardware level, but I'm just checking to be sure.

Thanks.

If reading GD fails, it will be another 10 attempts to read the sector. If the error is not passed, the sector is skipped.

Does DS output some kind of warning when that skip is made?

DS_ERROR: Can't read sector: %d
DS_PROCESS: Retry reading...

... 10 times

DS_ERROR: Can't read sector: %d
DS_PROCESS: Skip sector: %d
