How to convert a 1TB from NTFS to FAT32?

I bought a 1TB WD ELements hard drive. My Samsung BluRay DVD player will not recognise it.
I have read that some DVD players cannot read NTFS (my hard drive is NTFS formatted).
It picks up my flash drives which are in FAT32.
Can you safely convert a 1TB hard drive from NTFS to FAT32 without losing existing data on the hard drive? if yes, how do I go about this.
Thanks

There is 3rd Party Software that claims to do it without Data Loss eg. AOMEI Partition Assistant Standard Edition

But i have not personally tried it :neutral_face:

FAT32 does not support files over 4GB … so it’s pretty useless to me

All my Hard Drives are NTFS except my 2TB WD Elements which is formatted exFAT for my Playstation 4 (exFAT supports 4GB+ files)

Personally, i would recommend you Back-Up your Data before attempting any “Converting” … and also, you should always have a Back-Up of your Data even if you aren’t doing any converting.

Can’t stress enough how important it is to always have a Back-Up ! (have lost data years ago … and have learnt my lesson)
