Disk now fine after beeping issue [duplicate]

Solution 1:

like @Everett said: BACKUP NOW. but backup TWICE!

The question to ask yourself is : can you take the chance having the HD die on you?

At all time, critical data should be on at least 2 different backups, one close to the working pc/laptop, and one remote from it, in addition to your main location (ie, the working laptop/pc).

As the "local" copies (the working PC, and its local backup) could both fail at same time (ex: if flood/theft occurs).

That way, in case 1 or 2 of the copies fail (ie: you get robbed of your pc + the local external hd containing backups) : you'll have at least 1 other to recover from and quickly get back to the "safe" (well, safer) total amount of "2 backups media + 1 working media" at 3 (2 local, 1 remote).

Ask yourself: "what if i don't? What if I could lose all its content? Is it worth it?" (The answer to that could be "yes", but it heavily depends on the content. I assume in most cases the answer is "no, I prefer to spend money on 2 external (1 local, 1 remote) backup than losing it all")
