There are several basic scenarios when evaluating your drive problem.
Under normal operating conditions, it is rare that a drive’s physical mechanisms fail so badly the data cannot be recovered. Before assuming drive is physically bad, use the operating system drive tool to see whether the drive is still recognized. If it is, then likely, it is a file system corruption problem rather than a hardware failure. BACS can assist you with both types of problems.
When System Will Not Boot.
1. One check to see whether your drive is still physically operational is to view whether it appears in the system BIOS startup screen before the operating system attempts to boot. You may need to press F2, F10, ESC, or some other key combination unique to your computer model at the very moment it powers up to access the BIOS screens. If you do succeed in accessing data through use of a rescue startup disk or other method, immediately transfer your data to a backup medium such as an external USB drive before further failure prevents data recovery.
2. In the event of a drive hardware failure, two basic repair scenarios exist:
2a. The drive controller electronics have gone bad. This might be electrical surge burnout or other failure. It also may not be the drive at all, but the disk controller on your motherboard. One way to check is to plug in a different drive and see if it is recognized in the bios screen. If you are not familiar with computer repair, we highly recommend bringing it in for basic service. Drive controller boards (PCBs) can be replaced without breaking the drive seals, but some PCBs have memory chips that must match the drive serial data and may need to be physically transplanted from the old board.
2b. The drive heads or motor have gone bad, or have frozen to plate. Bad heads can cause further damage to the disc plate. If drive spins up, but data cannot be read, turn computer off immediately and have it serviced. This would especially be true if drive or computer has been dropped or otherwise impacted suddenly. If drive fails to spin at all, the motor may be bad. In either case in 2b, the seal on the drive itself must be broken for repairs, and doing so requires special equipment to prevent damage to the sensitive drive platters. Data recovery on this type of repair is best submitted to a data recovery professional. Expect to pay $500 or more for this type of data recovery.
In all of these scenarios, drive error failure means it is time to replace the hard drive. That process involves multiple time-consuming steps. In some cases it is both logically and legally possible to move everything to a new drive including the operating system and all of your data files. If drive has failed miserably however, a rescue of only your data may be your best option, while the new drive is freshly installed with a complete new copy of an operating system of your choice. Depending on the licenses that came with your computer, if you desire to use Microsoft Windows it may require purchase of a new operating system license . Other operating systems are possible that do not require license purchase. The cost for replacing a hard drive that is still readily accessible can be as low as $89 plus cost of the new drive itself, not including re-installation of additional programs that were installed after you purchased the computer.
