Same fdisk errors even after running fsck.ext4 on 16GB or 32GB microSD cards

[Sid Boyce]

To the other question, the new card reader is capable of handling 
microSD cards. I originally built the same on the same cards. It booted 
fine but problems only appeared after I added a number of packages. Some 
way through I got a message that it couldn't write to the filesystem.
Since then I ran into the problem. Even deleting the partitions and 
running the script again I hit the problem where the SD has the errors 
seen in the post.
It's possible the reader has developed a problem, so I'll get a 
different new one to try.
Regards
Sid.
