This is good news. I have some additional suggestions you may want to consider.
-Please back up your data. Important files should always be backed up to two media sources or locations. In the event of hardware failure, detection failure or formatting issue, you data will be safe and accessible while you are troubleshooting.
-Once your data is safely backed up, I’d recommend testing the drive using DLG DIAG. Data Lifeguard Tools is a free disk testing software that confirms a disk’s health and status. Link to software HERE
-Consider reformatting the drive. Start with a clean slate. Once you have tested and confirmed the drives health, reformatting will resolve any any discrepancies with the disk’s formatting or file system. At that point, you can recopy your data back to the drive.
Most importantly, please back up your data. All hardware fails (from any manufacturer). Replacing a failed drive is alot better than loosing important data or memories.
