Resolving Circuitry Error in Hard Drives

Newer hard drives are faster in speed and provide various advanced features. Thus, to incorporate this development and to make hard drive control better, all these modern hard drives are integrated with an intelligent circuit board- Hard Drive Logic Board. This board is responsible for supplying power and controlling all hard drive internals. The Logic Board is comprised of few basic components like: Control Circuitry, Interface Hardware, Firmware, Sense, Amplification and Conversion Circuits and Multiple Command Control and Reordering. At times, you encounter errors that hard drive circuitry is damaged and consequently, you cannot access the stored data. You will need to replace such damaged hard drive and restore lost data from the recent data backup available. In any case of backup concerns, you should consult professional Data Recovery Service experts.

As an instance, when you try to start your computer system, you might encounter the below error message:

“Hard drive circuitry error”

Such errors occur if hard drive’s control circuitry gets damaged. The control circuitry contains an internal memory, microprocessor, circuits and other structures that together function to control disk internals. Some of the basic functions of control circuitry include: managing hard disk read/write operations, controlling spindle motor and its speed, handling hard drive geometry translation, controlling actuator movement and more. The hard drive circuitry fails to perform any of these functions if is exposed to:

• Voltage fluctuations
• Faulty power input
• Vibrations and shocks

If hard drive circuitry or any of the Logic Board components fails, it is strictly prohibited to swap PCB by your own. It requires exact match of codes and parts and can not be accomplished unless both the damaged and healthy hard drives are from same batch. Thus, for safe and effective data recovery, you should seek technical assistance from Hard Drive Recovery technicians.

USB Data Recovery

A USB (Universal Serial Bus) drive is a flash memory data storage device integrated with a USB connector. These drives are compact, lightweight, removable and rewritable which makes them an ideal medium of data storage. A USB drive can be connected and disconnected without rebooting a computer. These drives do not need any external power supply and can be used with a lot of other devices such as printers, scanners, digital cameras, laptops, PDAs and personal media players.

A lot of computer users prefer to store data on USB drives as they are compact, faster, hold more data, are more reliable due to their lack of moving parts, and have a durable design. But as with any other storage device USB drives are also prone to problems.
There can be various problems such as power surge, improper usage, physical damage or a virus. If you encounter any of these situations, you will get an error message when you plug in your USB drive in a computer. The messages can be:

Status: Unreadable, Unknown Device
USB Device Not Recognized Window
Unknown Device
USB Unknown Device
USB Device Problem
USB Device Not Recognized in Windows
USB Device Not Recognized Windows XP

It you receive any of these error messages you will not be able to access your data on USB drive and the drive will not work. In that case you will need Windows Data recovery software to recover your lost data. It will be examined if a raw image of the data can be recreated and logical analysis will determine the severity of data loss. A logical recovery process will determine the damage to the file system and what can be done to correct it. An existing file system may be damaged and data may need to be extracted from the raw image. The data recovered will be analyzed any the errors will be removed using Windows Data recovery software. The data integrity will be checked after the data recovery process has been completed.

Data Recovery Services: yet not cheap

Hard disks differ from virtually every other component in the PC in one very critical respect: when you lose a hard disk you lose more than just hardware--you lose software and data as well. The hard disk can be replaced, but the data on it often cannot (and it certainly isn't covered by your warranty). This is why annoying people like me always harp on users to back up their data.
If for some reason you fail to heed my sage advice and do not back up your important data, it is still sometimes possible to recover it in the event of a hard disk failure.
There are data recovery services that specialize in restoring lost data from hard disks that have either failed or been corrupted due to software problems (accidental formatting, viruses, etc.)
Some of these services are pretty amazing--many of them have a very good success rate and can resurrect data even when it seems like it would be impossible to the casual observer. They use specialized equipment and software, and typically even have mini clean rooms that enable them to take the cover off the drive and access the platters directly. All this wizardry comes at a cost, of course. A full recovery usually starts at a few hundred dollars and proceeds from there. The cost is high for three reasons: the equipment is expensive, the people are highly skilled, and the company knows how valuable the data is or you wouldn't be talking to them. Compared to recreating a year's worth of data, $2,000 for a recovery is a bargain. Compared to doing routine backups, it's a colossal waste of money.
