hi..i am havin a lil trouble with my xtrnl hard disk(1 tb).it ws workin fine til the othr day and suddenly when i try to access the files and folders,they donot open and it says "not responding".All my data is in there,so please tell me what to do.
If it's mains-powered, try unplugging it from mains supply then plug it back in.
You need to keep your important data backed up to a second hard drive, one is not enough
A hard drive can fail without warning at any time, then your data will need very expensive professional recovery!
Believe me, I've been there. Lost 3 years of digital pictures. Lesson learned. Now I keep three backups of everything on three external hard drives.
