Hi,

I have a bad SSD drive. If I read it with dd and conv=3Dnoerror, what =
happens with the unreadable areas? Does it fill with zeroes, or does the =
driver still copy what it was able to read?

I=E2=80=99m getting ATA status 51 back, many blocks in a row. Followed =
by chunks of readable data, followed by unreadable data.

Is there a modepage or something else to tell the drive to pass on the =
bad data?

Any other ideas?

Peter
