My HD is **bleep**ed up

Hi all,

I have been using this HDD for sometimes but now It ask me to format it. I have a lot of  data on it but I tried it to no avail.

I can still connect and get to the security options asking for password but after the password then I get the format message.

Anyone help please

What OS and does the droive show in Disk Management and what does it say there?
