From a command prompt, run "chkdsk s: /f" to see whether there is any error on your S: drive.  Make sure that you use the /f switch so that any errors will be fixed.

You might want to change the USB cable and port as they may be faulty.

Make sure your job properties in your templates are selecting Media Set1

and go to Tools > Options > Device and Media> and choose Overwrite recyclable media contained in the targeted media set before overwriting scratch media

Hope this helps

Few observations from the above screenshots.

1) Media Set 1 has Overwrite Protection Period set as "Do not allow overwrite" and Append Period 

 as "Infinite allow append". This is not a good practice, at some point your destination device will have

no space for new backups if you do not overwrite older backup sets. Whenever backups are targeted

to a disk its recommended to Overwrite the jobs and not to append. So in the Media set 

properties set appropriate OPP ( For eg: If you want to retain data for 7 days than set the OPP as 

7 days so that 8th day onwards older backup sets will be eligle for being overwritten. This will help

you to utilitze disk space in a better way.

2) Check the B2D max file size, from the screenshot its seems you have set a large amount of

B2D file size( there are .bkf files with size between 150-250GB)  which is not recommended.

Set the B2D file size around 20-40GB ,with large size file you may loose all your data if that single

large file goes corrupt. 

If the issue persists try creating a new B2D folder.

 It looks like there are two media sets: Media Set 1 OPP - Do not allow overwrite , Append Period "Infinite allow append"    and Medis Set1 OPP - 1 Day , Append Period "Infinite allow append"   

kiuem, what version of Backup Exec are you using?
