External hard disk showing folder but can't access them

Hello,

My seagate 1 Tb hard disk is sowing the folder but I am not able to access them.
when trying to access the folder it shows error as:
"G:\Photos is not accessible
The file or directory is corrupted and Unreadable"

I tried doing G:\attrib -h -r -s /s /d g:\*.*
output:

G;\>attrib -h -r -s /s /d g:\*.*
Access denied - G:\$RECYCLE.BIN\S-1-5-21-2176504140-3805269354-1211177832-1001

Access denied - G:\found.000
Access denied - G:\System Volume Information


Also m getting error as below while the code was running:
"Attrib.exe-Corrupt File
The file or directory G:\Photos is corrupt and unreadable. Please run the Chkdsk utility."

Will chkdsk will delete the folder items.?
I need those photos and can't lost them...
