Windows 7 fails to store any data.
First verify two steps – attempt to save a large file to the disk, then restart and confirm its presence. If absent, connect the drive to another machine and test the same (treat it as a data source). Should the file disappear after restart in both scenarios, the issue lies with the drive itself. Consider updating the firmware. If you suspect a software problem, duplicate the drive to another location and verify whether the system behaves identically on the new drive.
