I accidentally removed my external usb drive without ejecting.
The next time I connected the drive Windows 10 prompted a scan to fix errors.
They were fixed after the scan and the hard drive connects fine but this drive is loaded with pictures and music.
What exactly did Windows fix and is there a way to find out if a file was lost?
If you used the chkdsk command to scan the drive, you can look into the associated event logs in Event Viewer to find the log recorded when the repairs were made. There's a TenForums tutorial on how to do this available at Read Chkdsk Log in Event Viewer in Windows 10. Chances are good, however, if chkdsk created no file fragment (.chk) files, nothing was lost. You will find such files in a folder named Found.000 at the root of the C: drive (or whichever drive is your primary Windows boot/OS drive) in individual files named File001.chk, File002.chk and so forth.
If you haven't got any such files (search on "File*.chk" to see) you have nothing to worry about.
If you do find such files, report back here to this thread and we'll figure out what to do next.
