Almost all computer users have experienced this at least once – the need to get back a deleted /lost data file. This could happen as a result of a software failure, hardware failure, human error, power related problems, damage caused by flood / water, vandalism, virus damage, damage by fire / heat / smoke and sabotage. Whatever the cause and reason that you need data recovery there is no reason to panic, for help is at hand. The need and urgency to recover data has resulted in a plethora of data recovery software to rescue you from a crisis like situation.Unless the hard disk is not working normally, the need for professional service is almost rendered unnecessary. If the hard disk is not making any weird noise like scratching, scraping or ticking (which means it is in good condition) data recovery can be done with the use of proper data recovery software, without the help of any technical personnel. The data recovery software that is available can be used for Mac, NT/2000/XP and RAID data recovery. The data recovery software is also FAT and MFT compliant.Hard drive data recovery is possible from small hard drives of 2 GBs to big hard drives of 120 GBs. Hard drive data recovery requires the presence of technicians if there is a hard drive crash.Data recovery software used for NT data recovery provides recovery of deleted files from the recycle bin, partition recovery from deleted partition or formatted logical drives, from lost folders and performs data recovery even if MFT is severely corrupted. NT data recovery software also recovers emails and all forms of files. Mac data recovery software recovers HFS and HFS+ File System Data. Mac data recovery software also recovers partition if partitions are deleted or formatted, files from Lost or Missing Mac folders. Mac data recovery software recognizes and preserves long file names when recovering Mac files and folders as well as provides full support for IDE, EIDE, SCSI and SATA drives.’Redundant Array of Inexpensive Disks’ or RAIDS offers better data recovery chances as long as the drives are cloned. RAID is a collection of hard disks that act as a single better hard disk than the individual ones. The hard disks of RAID operate independent of each other. A single drive failure is absorbed by RAID and does not result in loss of data. However, when RAID fails, it fails big time and then RAID data recovery software is used to retrieve data. Raid data recovery software recovers both RAID software and hardware.
