LANHAM, Md. (CBSDC) — If you have ever spent a lonely Saturday night “defragmenting your disc” at home, cheer up, it was not a waste of time.

Hard drives can spin 10,000 times per minute. You want to make it as easy as possible for the tiny magnetic heads that skitter around and read your hard drive. Defragmenting your disc reduces the amount of space they need to travel, as you work.

If you hear a clicking sound, your hard drive may be nearing the end of its days. PC World recommends backing up your data immediately and shopping for a new hard drive.

In addition to clicks, a PC’s whirring and clunking noises are warnings of other problems.

The Canadian hard-drive recovery company DataCent has posted some of the sounds made by failing hard drives. You can hear them online.

  1. Hard drives do many different noises, but not all of them bad. Clicking sounds are definitely not good, and can indicate problems with the read/write heads inside the hard drive. Continuing to run a hard drive with bad read/write heads can ultimately cause damage to the platters inside the drive, which is where data is stored. The damage could result in data loss.
