Nearly New Seagate 25 Tb External Drive No Longer Accessible

Hi,
I purchased a 25 tb external HDD and moved basically everything I care about onto this huge drive. In about 4 months I suddenly cannot access the drive. My guess is it is virus/malware related. It has been running chkdsk for the past 12 days and nothing (no status update, etc) so far. I know, shame on me for no real backup plan. I have since purchased a second drive to ghost but I need to access this one first. This drive has only sat on my desk since I started using it. Never taken it anywhere. Has never been knocked or banged or dropped in any way. No reason it shouldn't work unless it picked up a virus of some kind.

This chkdsk thing seems like a total bust. Any suggestions?

Will do. Thanks.

 

Chkdsk is not working since they windows cannot access the drive. They say to get professional help if that fails. Thanks for you concern.
