It’s inevitable in the average computer owner’s lifetime they will experience some kind of hard drive failure or data corruption through no fault of their own. What matters in situations like these to recover as much data as possible, and so save yourself hours of work recreating what you already had. The best thing a computer owner can do before a hard drive fails is to have a backup system or device, and find 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 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 (a sector 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 like Wholesale Computers & Technology carry out data recovery by opening the drives in a clean room and using appropriate equipment to read data from the platters directly.
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.
