hard drive recognized but not allowing me to store files

[Hanan_1]

So here's my problem, my external hard drive wasn't working properly so I formatted think it was a virus issue and now it is recognized on my pc and disk management but im having a problem now storing anything onto it. So I want to know what the problem is and how I can fix it.
Thank you.

What OS are you using? Did you use the HDD on a MAC or Apple device?
