Nothing can beat the panic of being unable to access all your data in your hard disk (except maybe your house on fire). The sheer volume of data that you have been keeping in your hard disk could be equivalent to your life's work. Although there are cases when the hard disk can't be recovered, there are also situations where the whole hard disk becomes functional again.
Hard drives are magnetic discs spinning around with an extended arm that collects data from the hard drive. When the arm doesn't function, or the disc stops spinning or gets overheated, your hard disk may crash and you won't be able to access all of your data. Finding out what was the major cause of your hard drive's malfunction is an important step in recovering the data.
One of the most important tools in recovering data from your hard drive is a software program for recovering data from hard drives. Several companies already offer these types of software programs that can automatically create backup copies of your folders and all the files in your folders. This move alone can mean a great deal when your hard drive crashes and you can lessen your worry if you have a software program that is able to prepare for the eventuality of your hard drive crashing.
When recovering data from hard drives, it is important that you know which file system your hard drive uses. The two file systems used by various Windows OS are NTFS and FAT. Both of these use the Master Boot Record (MBR) and partition table. These are found in the first sector or each hard drive. When either the MBR or the partition table is damaged, you won't be able to boot up and your hard drive will appear empty if information about the partition has been erased. If a partition table is damaged, that partition will appear empty. If you made a mistake and formatted your hard disk into NTFS and its filing system is FAT, your data will be lost. You need to unformat your hard drive.
Data recovery tools like data restoration software can recover data from the hard disk or even just a floppy drive. Data is easier to recover from NTFS, which automatically keeps a backup copy of your data, rather than from FAT, which is an older filing system and does not have a backup copy of the data from the hard disk or floppy disk. Partition recovery programs are plentiful but you have to purchase these. It is also advisable to get another hard drive or computer and boot from this, making the damaged hard drive into a secondary disk. This will enable you to transfer whichever data you will recover.
If you are unfamiliar with recovering data from a hard drive, it is better to take your hard disk to an expert and have it serviced rather than try to do it yourself. Although you may be apprehensive at having someone else handle your laptop's hard drive, getting an expert to handle the problem is the logical alternative.
