Dont use a partition assistant, the more you can strip out of the chain the easier it is to find the broken link so to speak.
Plug in the drive, does it appear with your other drives in My Computer? Can you format it from there?
Does it appear in device manager? (it probably does) does it report any problems with the device?
Have you tried to format it through Control Panel -> Admin tools -> Computer Management -> Disc Management ?
If it still wont format and the drivers are fine I would think it has some sort of write protection or something is physically wrong with it
Can you read and write files to the drive normally?
Have you tried a different PC?
No is the answer to all of your questions, I wouldnt have downloaded the partition assistant had it worked from my computer.
It can be seen in my computer in 2 partitions. If i try to go into it windows explorer freezes and when i right click and go into format it loads up the format options window but when i actually click format it freezes also.
I can however see the files on the drive through minitool partition tools professional, it has the typical files you would expect from a computer HDD the os and some files.
Any help would still be appreciated
Edit:I also tried a low level format which was also unsuccessful
