You started your Windows machine & everytime you're trying to open any application or trying to put in any program, you're encountering a mistake message. Moreover, your desktop icons along with some file/folders are missing & the system is exceptionally slow, though there is ample disk space available. Even, sometimes you may encounter a black login screen & issues in walking programs as administrator. The error message that you have encountered can be read as below:
'File System Error (65535)'
The error message that you get clearly indicates a feasible corruption to the file system of the pc, for which some files, folders & applications have already been inaccessible & if you would not take any measures to repair the same, the situation can be worse leaving all of your valuable information stuck in the hard drive.
In order to resolve the issue & recover hard drive data, you can run the 'chkdsk' from the command mode. The 'chkdsk' is a specially developed instrument to check the integrity of the disk & repairs, if it finds any kind of corruption/damage. If the 'chkdsk' fails to resolve the issue, then you can follow the below steps to get the issue fixed:
Go to Windows safe mode by pressing F8 at the system start-up.
Run the command prompt as the administrator by Start Menu > All Programs > Accessories – make a right click & select Run as administrator.
Then, type sfc /scannow. Note that there has to be a space in between sfc & /.
Note: This is the 'system file checker' instrument, which is meant to check all the Windows files for any instance of corruption.
If all the above measures fail, then there is one way left, that is to run any Windows hard drive recovery utility to recover back your seemingly lost information.
