UDFS FILE SYSTEM Windows 10

Here is how to fix UDFS FILE SYSTEM BSOD Error in Windows 10 –

1] Check for data corruption

Corruption of data mainly appears when the system or an application attempt to access a file stored in the hard drive. Once affected, you find the data unusable, unreadable or in some other way inaccessible. In worst cases, the system may crash with blue screen error especially UDFS_FILE_SYSTEM only if the data is related to UDF. Mostly, this happens due to lost data elements, misplaced files, jammed stacked items, incorrect order and several more factors. To check the utility and repair it as well, follow the below steps –

  • Press Win+E to invoke File explorer.
  • Right-click on C: drive and choose Properties.
  • Jump into Tool tab and click the button Check located beneath Error checking.

This time, two different situations can arise. Both are described below –

Situation-1:

  • If the system gets an error, you will be asked to check the disk. Click the checkbox for “Automatically fix file system errors” and subsequently select the Start button.
  • If the drive is currently in operation which you want to check, a warning-pop up will show up. In this case, click Schedule disk check.
  • Thereafter, close all ongoing programs and restart Windows 10.
  • Next time after a reboot, disk checking will automatically start and throw you the results once completed.

Situation-2:

  • When data corruption, is not detected a message stating “You don’t need to scan this drive” appears. Here, you may go with advanced disk checking as an alternative. For that, click Scan drive.

  • After completion, the utility will either confirm if the error was found or not. In case of getting any, click the option named Restart your computer to repair the file system. You can either reboot right now or schedule the checking and fixing on the next restart.

2] Fix corrupted hard drive to fix UDFS FILE SYSTEM

You may get confused with error checking utility that we described just above and chkdsk command line as both are similar to some extent. Before you skip the resolution, let us make it clear to you right away. Error check has mainly 3 phases such as chkdsk in read-only mode, chkdsk /f that works when you choose Automatically Fix File errors and chkdsk /f/r which attempts to recover bad sectors. Usually, we take help of the second one as a preference which really doesn’t do a detailed test of the hard drive. chkdsk /f/r checks the existing files in the hard drive including empty space to detect and resolve any file system structural corruption. Though the process requires more time, this workaround worth a try. Steps are as followed –

  • Click on search icon from the taskbar and type cmd.exe.
  • Choose Run as administrator option from the right flyout.
  • Opt for Yes button on the User Account Control.
  • Put the following command-line and hit Enter –

Chkdsk /f /r

  • To confirm it, type Y and press Enter.

Hence, reset all the connectors to make sure the cable is plugged safely and you didn’t leave it loose. Moreover, if you are using SCSI drives, terminate them correctly too. For further checking, you can test the drive in another system that is absolutely fine. Most of the UDFS_FILE_SYSTEM  blue screen error comes up due to faulty hardware. To check it on your own, you can examine the temperature of the connected accessories. If it feels hot, we are pretty much sure that you have a thermal hardware problem. In such a case, either take help from the professionals or replace the faulty item with a new one.

Another root cause to bug check code 0x0000009B is failure of Random Access Memory. To diagnose it, here is the process you need to follow –

  • Save and close all the ongoing processes.
  • In the Windows taskbar search, type Windows Memory and hit Enter.
  • Click the option named Restart now and check for problems (recommended).
  • Windows will restart automatically and start checking the RAM.
  • After completion, you will get the details of the action through the notification bar.

Non-paged pool is used by drivers to apportion space of disk drive that is unusable even if the system runs short for free physical memory. Once it becomes full, several errors make an appearance such as Windows 10 blue screen error UDFS FILE SYSTEM in order to stop the system. However, there is a way to try out for fixing this issue, otherwise, you need to add extra physical memory.

  • Hit Yes if a UAC turns up.
  • Navigate the following directory –

Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Memory Management

  • Move to the right-hand side and look for NonPagedPoolSize DWORD key.
  • Once found, right-click on the same and select Modify.
