Formatting external drive takes forever!!

Hey guys. I am trying to format this external hard drive but it is taking forever even on quick format! Just a little background info first. I got the hard drive from my cousin since he didn't want it. It had maybe 10 songs on it and that is all. I tried to format it and it took too long (I probably just got impatient) so I tried to cancel it and the format would not cancel (keep in mind the drive had no problems I was able to copy and remove files no problem before this). So I unplugged the drive from the USB port, I know, stupid move. I plugged it back in and it was converted to RAW file system. I thought maybe if I performed a low-level format and then tried to "high-level" format it, I could get it back to NTFS. The low-level format took 3 days I believe, and when it was finally finished my external drive wasn't even recognizable -____- I unplugged both the power and the USB from the drive and it was recognizable again. I created a partition using EaseUS with no problem. Then when I went to format the partition (I only created the partition did not format yet), EaseUS hanged at 40%. I was able to cancel it and then try to format it from My Computer, again took very long (keep in mind I clicked "quick format" in both cases). I also tried to format using the command prompt (DISKPART) and every time after I create the partition and I try to format it to NTFS it says the disk is not online, then i type in the "online disk" command and it tells me that the disk is already online. Very confusing.

Also if I require to erase everything off of this drive I have no problem in doing so (as you can see). Any help would be greatly appreciated I want to backup my system to this external drive! Thanks in advance
