{ DRDY ERR },{ UNC } and Error 096 on 1006-x router, while file coping

[Ram1100]

I got the below error while coping a OS file form hard disk to the standby hard disk on CICO 1006-x router, Can someone explain what this issues is and how to fix this. Suspecting this is hard disk issue,

Error 096 in res 41/40:08:18:20:00/00:00:00:00:00/40 Emask 0x409 (media error): This indicates a media error, which typically means there is an issue with the hard disk itself, such as bad sectors or a failing drive.
%IOSXE-3-PLATFORM: R0/0: kernel: ata1.00: status: { DRDY ERR }: The "DRDY ERR" status means that the device is ready, but an error has occurred.
%IOSXE-3-PLATFORM: R0/0: kernel: ata1.00: error: { UNC }: The "UNC" error stands for "Uncorrectable Error," which means that the data on the disk cannot be read or corrected.

I tried to copy the files from remote server, but not alloing and giving the below error

%Error opening harddisk:/Test_file.txt (Permission denied)

      Yes the hard disk is failing ; check if you can   do   
      router      # fsck   harddisk:

            You will probably need to replace it ,
