Hard Drive Failures

Hard Drive Failures

It is technically possible to do the most elementary hard drive repairs yourself, but the worse the damage, the more absolutely you will need specialized tools and knowledge. The best thing a computer owner can do before a hard drive fails is to have a backup system or device and find the number of a suitable drive repair/data recovery company. The ultimate goal here is simply to copy all important files, or as many as possible, from the damaged media to another new drive.

Hard drive failures

Hard drives may fail in a number of ways, but most common are head crashes -where the internal read-and-write ‘head’ of the device, usually just hovering above the surface, touches a platter, or scratches the magnetic data-storage surface- or bad sectors, which are the ones on a computer's disk drive or flash memory that is either inaccessible or unreadable due to permanent damage, such as physical damage to the disk surface or failed flash memory transistors. Data from a failed drive can sometimes be partially or totally recovered if the platters' magnetic coating is not totally destroyed.

Specialized companies carry out data recovery, at cost, by opening the drives in a clean room and using appropriate equipment to read data from the platters directly.

What to do when a hard drive fails

It is important that computer owners can quickly recognize the signs of a failing hard drive, such as disappearing files, repetitive computer ‘freezing’, corrupted data, bad sectors, and most importantly odd sounds such as clicking, grinding, screeching, or whirring. These sounds could be the read/write heads hitting or scraping the hard disk platters, and severe or complete data loss could result.
