Disregarding the security issue that you cannot "browse" local files with a website, your question should be answered:
When requesting a PERSISTENT filesystem you have to request a quota in first. Try that instead:
window.storageInfo.requestQuota(PERSISTENT, 1024*1024,
function(grantedBytes) {
window.requestFileSystem(window.PERSISTENT, grantedBytes, onInitFs, errorHandler);
},
errorHandler
);
