This is how bad sectors appear. WD drives are very vulnerable to overheating, power surges and streaks. After some period of time magnetic media the platters are covered with starts to degrade and magnetic domains can’t turn in the desired direction by writing element of the head. Main part of firmware is stored on the platters in so-called Service Area. Stay away from those companies.

If one of the modules gets corrupted the hard drive fails to initialize correctly and stops working making the data inaccessible.
Firmware of the drive is not located on the logic board as most people think. The problem is that logic board on modern hard drive is adapted to the head disk assembly it was manufactured with. All Western Digital hard drives are also well-known for their firmware problems.
Drive Western Digital – will not mount, or boot up in target mode, or function as external HD. Immediately after the motor stops spinning they stick to the ideally smooth surface and it becomes impossible to free them without proper tools and experience. If you experience any of the symptoms described above with your Western Digital WDJBREA0 please feel free to contact us to get upfront quote on data recovery from your failed drive.
I was able to use DataRescue to recover a few files and it had no problem scanning the drive, but it, too ended up being non-responsive. We see mostly failed drives in our lab and therefore we don’t have complete statistics.
Stay away from those companies. It mounts in target disk mode on another laptop and at first would allow browsing of the file structure, but then when trying to copy files off I heard the scratching and then it became non-responsive.
When the drive starts reading data from such unreadable bad sector it could wd250jb-00rea0 freezing, scratching and sometimes even clicking: We are not affiliated in any way with hard drive manufacturers.
After some period of time magnetic media the platters are covered with starts to degrade and magnetic domains can’t turn in the desired direction by writing element of the head. Usually this is a sign of damaged or crashed heads and it qd2500jb-00rea0 the drive needs to be opened in a class clean room environment in order to replace head stack assembly.
All this leads to further damage to the surface, heads and causes more data loss.
Western Digital drives also have common problem with spindle seizure. The drive spins up, and and the heads start clicking with a constant or intermittent sound while unsuccessfully trying to locate firmware zone: Heads are normally parked on the parking ramp outside of the platters, but sometimes after a fall or abnormal termination they fail to return to their regular parking position and are left on the surface. In our lab we use specialized software and hardware to rebuild these parameters or transfer them from fried board to make donor PCB fully compatible with damaged drive.
Insert system disk and press enter”, “Hard drive not recognized”, “Drive Mount Failure” or some other hard drive boot error.
That’s usually the only way to retrieve as much files as possible from such sectors. Any further reading attempts would just add up to the problems and could make your data unrecoverable. It is quite a complicated job and requires use of specialized expensive equipment and deep knowledge of hard drive design and data recovery technology to repair the firmware.
Service Area occupies the negative cylinders of the surface and contains a number of firmware modules.
We have seen a number of websites lately cloning information from our pages. If you hear your Western Digital hard drive making some other unusual noises visit our Hard Drive Sounds page for more examples.

Capable But Command Failed” or “Disk boot failure. There is one more problem that is typical for all Western Digital drives: Usually this occurs after a fall and the drive either doesn’t spin up at all with a siren sound: This complex and precise procedure requires a lot of experience and use of specialized hardware to maintain platters in perfect alignment. This is how bad sectors appear.
Should this occur the computer would reboot or shut down completely, you would normally notice acrid smell of smoke coming from your PC and when powered on the drive would not spin up at all and appear to be completely dead.
In our lab we use special imaging hardware tools that are capable of reading raw sector data ignoring low level checksum check. Copenhagen, Denmark All Western Digital hard drives are also well-known for their firmware problems.
