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.

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.

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.

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.

I Think My Hard Drive Is Failing, What Shall I Do?
• So you are worried that a hard drive failure is just around the corner? The truth is, even if you are not worried, it is!
• The only thing you can do is always keep backups of your data on a second hard drive.
• The likelihood that both drives will fail simultaneously are very rare. An exception would be natural disasters like floods or fires.
• For these cases, I recommend to keep a copy of your most important data in a different physical location, for example at work or with a friend, or possibly on a remote server, for example by using an online backup solution.
