External Hard Drive

I recently bought a 2tb external hard drive from Ebay. I have been messing with it and it now says it is RAW configured, not NTFS. I've tried various things from the internet to try to change it back into NTF, using DISKPART and CHKDSK, but they didn't work, only having a very limited knowledge as to what I was doing, I fear that I may have done more damage, is there any way that I can get it to work again, There is nothing on the disc, Thanks for any advice that anyone can let me have. Been looking at similar posts, but nothing stands out. Thanks

First of all, what have you plugged it into and what operating system is it running?

Thanks for your reply, it is a Packard bell laptop,running windows 10,also tried it on my desktop computer,a Dell computer,using windows 10.

Try installing the free MiniTool Partition Wizard and then change it through that.

Windows disk manager, delete the partition, then just set up as a new drive

Thanks for your replies, I'll give them a go. and hopefully let you know of a happy outcome.

Just open in windows and right click on the drive, format? selecting the required file system?
