6 Bad Blk: 0 1 3 5 539 620 1050

0 and 1 seem rather frequent.

Yes 0 and 1 do seem to be marked bad for everybody, and block 0 is the only block guaranteed to be good by the manufacturer. That's enigmagic.

Don't know why they're listed as invalid, but no way is block 0 invalid nor probably block 1 in everybody's Prime. Here is the direct quote from the manufacturer's data sheet: "The 1st block, which is placed on 00h block address, is guaranteed to be a valid block up to 1K program/erase cycles with 1bit/528Byte ECC."
