My passort went from a 1T to 32 gig

My passort is being very weird when I bought it a few years ago and when I purchased it the size of the drive was 1T and now it is reading as a 32 Gig so I would like to have it back to what I purchased it as. so my question is how do I change this or fix this problem.

sounds like it’s been formatted it FAT/FAT32

because 32GB is Maximum Size the Windows will format a Hard Drive to.

Reformat it to a file system that supports over 32GB eg. NTFS, exFAT, HFS etc
