How to set in console in 'format' command parameter /A: more than 8Kb?

Hi,
/A:8192 is the last that works. If I try /A:16384 it failed with error: "bad parameter /A:16384"
The whole command is:
format e: /fs:FAT32 /a:8192

According to the help (format /?), 16000 is the number, not 16384 (regardless the real cluster size afterwards will probably be 16384 bytes).

I tried /A:16000 and /A:32000 the same error: "Wrong parameter"

Are you running the cmd as administrator?

Yes.

You want to say that you tried what suggest and it works?

Type format /? at the command prompt and you will see the proper syntax is /a:16K. I have tried this and it works.
