I/O errors and undeletable directories

For some unknown reason, there are 2 directories I can't delete. First directory called **sw.old** is empty and can be deleted only by rm, as rmdir won't recognize it. However, even after rm, it still shows up: [02:11:36] user@user:/media/user/exthdd/docs$ ls -il total 1072064 1456 drwx------ 1 user user 0 Aug 12 10:04 1old.or.probably.unfinished 5717 drwx------ 1 user user 8192 Jan 27 22:58 videos 6528 -rw------- 1 user user 1097779088 Nov 5 16:15 release_Remix_OS_for_PC_Android_M_64bit_B2016112101.zip 8008 drwx------ 1 user user 4096 Jan 28 00:55 txt 64 drwx------ 1 user user 0 Dec 25 22:15 sw.old [02:12:03] user@user:/media/user/exthdd/docs$ rmdir sw.old/ rmdir: failed to remove ‘sw.old/’: No such file or directory [02:12:57] user@user:/media/user/exthdd/docs$ rm -rf sw.old/ [02:13:15] user@user:/media/user/exthdd/docs$ ls -il total 1072064 1456 drwx------ 1 user user 0 Aug 12 10:04 1old.or.probably.unfinished 5717 drwx------ 1 user user 8192 Jan 27 22:58 videos 6528 -rw------- 1 user user 1097779088 Nov 5 16:15 release_Remix_OS_for_PC_Android_M_64bit_B2016112101.zip 8008 drwx------ 1 user user 4096 Jan 28 00:55 txt 64 drwx------ 1 user user 0 Dec 25 22:15 sw.old Second one called **misc** has a corrupted file inside it: [02:24:32] user@user:/media/user/exthdd/docs/txt$ ls -il total 0 22607 drwx------ 1 user user 0 Dec 31 16:09 misc [02:24:36] user@user:/media/user/exthdd/docs/txt$ ls -il misc/ ls: cannot access misc/patterns.mp4: Input/output error total 0 ? -????????? ? ? ? ? ? patterns.mp4 [02:24:54] user@user:/media/user/exthdd/docs/txt$ rm -rf misc/ rm: cannot remove ‘misc/patterns.mp4’: Input/output error How can I remove those directories (and corrupted file inside one of them) without formatting?
