DISKPART> create partition primary

No usable free extent could be found. It may be that there is insufficient
free space to create a partition at the specified size and offset. Specify
different size and offset values or don’t specify either to create the
maximum sized partition. It may be that the disk is partitioned using the MBR disk
partitioning format and the disk contains either 4 primary partitions, (no
more partitions may be created), or 3 primary partitions and one extended
partition, (only logical drives may be created).

Hey there, @Allan81904,

It’s been a little while since I had the (mis)fortune of using Windows CLI, but from memory that means that the old partition table is still there so a new partition cannot be made.

After selecting the disk for your SD Card, could you try running the clean command before retrying create partition primary.

That should remove the old table and let you create a new primary partition. It’s also a lot quicker than going through and deleting each partition manually.
