I don't think you can unless you have auditing on (or some software to track all changes).
I would check the Recycle bin to see if it is there. Also check your AV in case it has quarantined them (if applicable)
I would also run a SMART tool just to ensure the hard drive is behaving.
And run Chkdsk /f
from the command prompt
This is how to turn on Auditing in Windows
To set up auditing, modify the group policy affecting the server
containing the files. You need to navigate to Computer Config, Windows
Settings, Security Settings, Local Polices, Audit Policy, and set the
"Audit Object Access" setting to audit for Success and/or Failure.
Then, navigate the folder that you wish to audit, bring up its
properties, then security. Click on "Advanced", and then the auditing
tab. From here, you can add users or groups to audit for this folder,
and define what actions to audit, E.g. Delete, Delete Sub Folders and
Files, Modify Etc.
Any collected data will appear in Event Viewer, under security.

OR
Enable file auditing in Windows to monitor events related to users
accessing, modifying, and deleting sensitive files and folders on your
network. To maximize the value of this type of auditing, enable
auditing on a file server on which you have installed a LEM Agent, and
only for the specific files and folders you want to monitor. If you
enable auditing on all files or folders, or even a large number of
them, you will create an unnecessary burden on your LEM appliance by
telling Windows to log events you don't want or need to see.
Complete the two-part process below to first enable object auditing on
your server, and then enable file auditing on the files and folders
you want to audit. Provided Windows is logging the events and your
server has a LEM Agent installed on it, your LEM Console will begin
displaying the new file auditing alerts immediately.
To enable object auditing in Windows:
Open Administrative Tools > Local Security Policy.
Expand Local Policies and click Audit Policy in the left pane.
Select Audit object access in the right pane, and then click Action > Properties.
Select Success and Failure.
Click OK.
Close the Local Security Policy window.
To enable file auditing on a file or folder in Windows:
Locate the file or folder you want to audit in Windows Explorer.
Right-click the file or folder and then click Properties.
Click the Security tab.
Click Advanced.
Click the Auditing tab.
If you are using Windows Server 2008, click Edit.
Click Add.
Enter the name of a user or group you want to audit for the selected file or folder, and click Check Names to validate your entry.
For example, enter Everyone.
Click OK.
Select Success and Failure next to Full control to audit everything for the selected file or folder.
Optionally, clear Success and Failure for unwanted events, such as:
Read attributes
Read extended attributes
Write extended attributes
Read permissions
Click OK in each window until you are back at the Windows Explorer window.
Repeat these steps for all files or folders you want to audit.
