16.04 - Error While Deleting - File Doesn't Exist - Ask Ubuntu

somehow managed create file on nas drive contains forward slash in file name (i.e. '/'). think has caused problem.

now trying delete file gives me "error while deleting - file doesn't exist" message. i've tried using terminal this, gives me 'input/output' error message.

checking out various forums have suggested might issue hard drive , run dmesg, did , output voluminous, contained lots of sections looked this:

[130690.519285] sr 1:0:0:0: [sr0] tag#0 failed result: hostbyte=did_ok driverbyte=driver_sense [130690.519290] sr 1:0:0:0: [sr0] tag#0 sense key : not ready [current]  [130690.519292] sr 1:0:0:0: [sr0] tag#0 add. sense: medium not present - tray closed [130690.519294] sr 1:0:0:0: [sr0] tag#0 cdb: read(10) 28 00 00 00 01 23 00 00 01 00 [130690.519296] blk_update_request: i/o error, dev sr0, sector 1164 

which doesn't @ all. i've used various scans on nas drive (which wd mycloud mirror) far have come negative (admittedly haven't run longest ones yet).

appreciate ideas go now? guess formatting drive option, thought there might simpler fix...

the sr0 errors dvd drive. not related file problem.

1. open terminal ubuntu dashboard
2. cd {to_the_directory_that_contains_the_bad_file}

3. try either one/both of following commands try , delete file:

   sudo rm -i *00e12.avi sudo rm -i "battlestar galactica\/ blood & chrome s00e12.avi" 

report back.
