1. Slowing Down Computer, Frequent Freezes, Blue Screen Of Death
These are very unspecific signs that can be caused by a million different things. However, regardless of what the issue behind these symptoms is, it is recommended that you immediately make a backup. If these problems occur after a fresh installations or in Windows Safe Mode, it is almost certain that it is due to bad hardware, and possibly a failing hard drive.How To Start In Windows Safe Mode & Its Uses How To Start In Windows Safe Mode & Its UsesREAD MORE
2. Corrupted Data
If you’re beginning to find files that fail to open and are corrupted even though they saved without errors or if files suddenly disappear, you should get worried. While again this could be due to a multitude of issues, it is also a typical sign for a gradual hard drive failure.
3. Accumulation Of Bad Sectors
Bad sectors are areas of the hard drive that do not maintain data integrity. They are automatically masked by the operating system and thus hard to identify, especially if large amounts of the disk are currently in use. If you actually run into bad sectors, however, that certainly is a bad sign.
You can run a manual disk check to identify errors that Windows has not spotted, yet. In Windows 7, go to > Start > Computer and right-click on the disk or partition you wish to check. Select > Properties, in the window that opens switch to the > Tools tab and click > Check now… In the Checking Disk window place a checkmark next to > Automatically fix file system errors and > Scan for an attempt recovery of bad sectors.
Windows will also check for bad sectors, when you perform a full format or chkdsk command.

4. Strange Sounds
When you hear strange noises coming from your hard drive, it may be too late already. A repetitive sound also known as the click of death is caused by the head as it is trying to write data and recovers from errors in doing so. Grinding or screeching noises indicate that parts of the hardware, for example the bearings or spindle motor, are failing.
5. S.M.A.R.T. Data
There are tools that aim to predict hard drive failure by reading the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data that is recorded by the operating system. Unfortunately, like most other methods listed above, S.M.A.R.T. is notoriously unreliable in predicting hard drive failure and the catastrophe will often happen before the warning of S.M.A.R.T. kicks in. If you have a working hard drive, however, and would like to have a look at its S.M.A.R.T. data, check out this article – 4 Tools To Predict and Prevent Hard Drive Failure
