Computer does not recognize external hard drive

Hi all,I googled this but I really can't find an answer,hear goes.I have 2 seagate external hard drives with
all my movies and tv shows.I plug it into my dvd player and watch them on my smart tv.I bought a new one which says seagate external expansion drive.It is not recognized when I plug into the dvd player.Did
I make a boo-boo and buy the wrong one.Any help would be appreciated,thank-you.

Yes,a boatload of usb ports on tv and puter recognizes new external.Checked my 2 old ones and the new one and all are
ntfs.All externals are 4terabytes and the 2 previous ones work but not the new one,don't understand it.I just plugged it in to one of the usb ports on the tv and it works.Guess I ain't to bright.Guess that's why they call it a smart tv,never thought to look.Thank-you so much for pointing me in the right direction.

There remains one possible difference. Check to see if the new one is a GPT partition and the old (working) ones are MBR. Your DVD player may only understand MBR partitions.

You can check in Disk Manager. Right-click on the disk disk's name (Disk 1, Disk 2, etc) to the left of the display of partition(s) for each drive. Select 'Properties'. The 'Volumes' tab will tell you the partition style.

You are correct,2 old ones are MBR and the new one is GPT.Now is there anything I can do about it.

One other thing to check, my new 4TB USB 3.0 drive came formatted as exFAT.

Yes. There's a tutorial for that.

Convert GPT Disk to MBR Disk in Windows 10

Will try it and thanks to everyone for the help,much appreciated.Will let you know how I made out,Tony.

Here is an update,formatted to mbr,works good and dvd player recognizes it.One drawback,I don't know if I did something wrong but I followed the tutorial to the letter.Formatted only 2 terabytes,the rest is unallocated and probably unusable but that's ok.

Have you tried Disk Management to create a new Primary partition in the remaining unallocated space?
