Convert 3.0 usb to 2.0

Is it a 3.5’’ drive or 2.5’’? Does the drive use its own power cable? Since it is a 5 TB drive, I presume it has one single partition. Is that correct? If it is so, the hard drive may be formatted in GPT in order to show you all the 5 TB. The DVD may not support that.
In order to check it, backup all data and try initializing and formatting the drive, creating new MBR partitions. Have in mind that MBR supports up to 2 TB partition size.

I was talking about the dvd player yeh the hard drive has his on power cable i formated the hard drive to fat 32
Fat 32 always worked on my dvd player but the 5 tb hard drive for some reason is not working wich is weird beacuse if 3.0 cable is suitable for 2.0 i have no clue i will format the hard drive again but i have to do 3 parttions on it because fat 32 only supports up to 2 tb aswell i have to do 3 on it .. what a head ache ..

I believe you have done everything right. The GPT – MBR switch may solve the issue for you and you should really try it. I leave you some links with step by step guides. Remember to backup all important data before starting.

Both links represent basically the same action but explained in a different way. Firstly, I would try using the Disk Management. Delete all volumes and when you have one big unallocated space, select Convert to MBR. Partition the drive the way you like it and format it in FAT32. Check again with the DVD.
