Laptop Vaio VPCEB14EN, Segate 320gb HDD, Win7 basic
I am receiving smart failure error from about 8 months. But nothing serious has happened till now. Although I have backed up important data, do u think that I should replace my hdd?
Yes I do!
Of course, it may depend on the error, but if it signs as 'dangerous' or 'serious' or similar, time to change.
Although if it were my money, I'd probably consider at intermediate issues.
Now, your issue states Failure, and each SMART tool can report slightly differently. If this was a one off, I'd probably ignore it, if often then I'd replace the hard drive.
Either way, keep backing up!
