NAME
git-annex checkpresentkey - check if key is present in remote
SYNOPSIS
git annex checkpresentkey key [remote]
DESCRIPTION
This plumbing-level command verifies if the specified key's content is present in the specified remote.
When no remote is specified, it verifies if the key's content is present in any accessible remotes.
Exits 0 if the content is verified present in the remote, or 1 if it is verified to not be present in the remote. If there is a problem, the special exit code 100 is used, and an error message is output to stderr.
OPTIONS
--batchEnables batch mode. In this mode, the
keyis not specified at the command line, but theremotemay still be. Lines containing keys are read from stdin, and a line is output with "1" if the key is verified to be present, and "0" otherwise.Also the git-annex-common-options(1) can be used.

It makes sense that checkpresentkey could report different information than whereis, because whereis only reports on logged location information, while checkpresentkey actively checks the remote.
I'm not entirely clear on how an external special remote could not support checkpresent, I suppose you might mean it always fails or is just not implemented (so basically fails). That would be a problem with the remote's implementation. If it's something else, open a bug report.
