CrystalDiskInfo is a great program, but, to me, seems to be a bit paranoid. I would try an actual S.M.A.R.T. test as well. To do a quick S.M.A.R.T. check without installing any third-party software, you can use a few commands included with Windows. First, open a Command Prompt window. (Press the Windows key, type Command Prompt, and press Enter.)
In the Command Prompt window, type the following commands, pressing Enter after each:
Code:
wmic
diskdrive get status
If everything is working properly, you should see the status OK displayed. Other statuses can indicate problems or errors retrieving S.M.A.R.T. information.
If you have used either of these tools – or another reputable program – and have seen an error, this does not mean your hard drive is going to fail immediately. However, if there’s a S.M.A.R.T. error, you should assume that your hard drive is in the process of failing. A complete failure could come in a few minutes, a few months, or – in some cases — even a few years. However long it takes, you should not trust the hard drive with your data in the meantime.
