If you have no data on the device, just do the steps like in post #12 of this thread, this will aply a fresh new file system on the partition. A reboot or mount of the partition to /home/user/MyDocs should be sufficient to get rid of the error.
If, however, there was data in the MyDocs partition, which you like to get back, do the steps in post #2 line by line to check the file-system and repair it.
