How to Restore Factory Capacity of Hard Drive?

DATARECOVERYUNION.COM03 mins

How to restore factory capacity of hard drive This post is a complete guide on recovering your hard drive’s factory capacity.

Reasons why hard drive might lose some megabytes or even gigabytes:

  • Your Operating System does not support LBA48 addressing mode
  • You are mixing binary and decimal gigabytes
  • Your motherboard has created a hidden area on your hard drive to store a backup of the BIOS binaries
  • Your PC/Laptop manufacturer has created a hidden area on your hard drive to store a backup of the Operating System installation files (needed for automatic restore functionality)
  • You have used some software that sets HPA (Host Protected Area), messes with DCO (Device Configuration Overlay), or switches off LBA48 support
  • You have misplaced a jumper on the drive
  • There was Magic involved

Solutions to Restore Hard Drive Factory Capacity :

  1. Check jumpers. Consult with manufacturer’s instructions and set jumpers to the proper position.
  2. Check your OS, does it have all updates installed?
  3. Check disk partitions. Run Windows Disk Management console and see if there is any free space that is not used by any partition.
  4. If steps 1—3 did not help, then we have a very cool tool that analyzes your hard drive’s LBA48, HPA and DCO status and recovers factory settings

Useful Tool: HDD Capacity Restore v1.2

License: Freeware
Author: Atola Technology
Supported hard drives: all hard drives
Supported OS: 32-bit versions of Windows XP/Vista/2003

HDD Capacity Restore Tool allows you to restore factory capacity of any hard drive. It does everything automatically: it extracts the factory capacity; then it restores the factory LBA48, HPA and DCO settings.

In some cases this program allows to actually increase the capacity of a hard drive (if it was limited by the distributor; for example, Hewlett-Packard sometimes sells 80-GB hard drives but sets a 40-GB limit. You can restore the full 80-GB capacity in this case).

Data Recovery User Guide – Through Data Recovery Software

DATARECOVERYUNION.COM05 mins

Data Recovery User Guide According to Murphy’s Law of Data Loss, “The probabilities of a hard disk crash increase with the number of days since the drive was last backed up.” No hard disk drive is ever completely safe from crashing, and losing all the important data on it.

A disk drive can be damaged due to a number of causes such as virus attack, voltage glitches, software malfunction, hard disk format, accidental file/directory deletion, human error or even sabotage. Such events cause corruption or damage to the disk drive, and make the data completely inaccessible to the user.

Data Recovery comes into play when your storage stops responding to your request. This is the most critical time for your data and the impending problem with the hard drive. A wrong step can make your hard drive & data inaccessible for ever. First and foremost thing is Don’t Panic!

Now check whether you have a physical failure or logical failure. Normally in 80% of cases there is a logical failure. To know the type of failure you have hear whether any ticking sound is coming from the hard drive or not? If not that means that it is a logical failure and you can recover your data through data recovery software.

You can choose the data recovery software by searching on Google with keywords like data recovery software, hard drive recovery etc. (See Best Data Recovery Softwares 2009 ) Whilescanning different software product consider these factors:

See to this whether the software supports your systems hardware like RAM (Random Access Memory), Operating Systems (particular Window flavors, Unix, Linux, Solaris etc).

You must check your RAM before installing the data recovery software, as these software uses recursive search operation which requires lots of virtual memory. For a fast recovery you have large size of virtual memory. I would recommend 256 MB or 1 GB would be best.

After selecting the software it’s the turn of software Installation. NEVER means NEVER install the software on the same physical drive from where you have lost your data. As it may get over written and you will lose it for ever.

Always use a working computer with a drive having enough free space to store your recovered data.

Verify that the drive in the PC is connected on the Primary Channel as Master.
You can connect the drive as:

• Slave on the primary channel OR AS
• Master or Slave on the secondary channel

Note: You can take help of support executive in your office or your maintenance engineer if you are not comfortable in connecting the drives.

Attaching the Drive in to slave has three simple steps:

• Set the jumpers on the hard drive or CD ROM
• Plug and screw the drive in
• Boot the computer up and make sure the drive is detected
