Problem

When I enable disk collection from host_metrics I get this error:

Uploading the log output has crashed gist twice, so I cannot share it that way. Here is a google drive link https://drive.google.com/file/d/17fVVL7ljtV1MF8FOazhRD4p2Pf_9pXNY/view?usp=sharing

i imagine this is related to how errors are handled in the heim fork's windows bindings

match e.raw_os_error() {
    // See function doc
    Some(ERROR_INVALID_FUNCTION) => Ok(None),
    Some(ERROR_NOT_SUPPORTED) => Ok(None),
    _ => Err(e.into()),
}

for raid volumes that dont have accessible device paths, windows returns volume guids, which fileapi::CreateFileW cant find, returning ERROR_FILE_NOT_FOUND. we probably just need to handle this error either by patching heim or by rewriting disk.rs to not use heim::disk::io_counters()
i can probably take a look within the next couple of days
