Thank you for the quick response.
Once the Scanner gave me the first file system error message, I ran CHKDSK and it didn’t report any errors. I also put it into another system and ran CHKDSK again without errors. Once I confirmed the disc was fine, I put it back into the array and cleared the errors manually. This is when I noticed that it was still reporting the previous disc size. I reset all drives in Scanner, it scanned all discs fine and reported no errors, however the size never changed. I have attached screenshots:
