How To Recover Deleted Data From Computer,Pds Or Memory Cards

Sometimes we face a difficult situation when we accidentally deleted our data from computer,memory cards or pen drives and want to get it back. Many times we are lucky to get back our deleted data from recycle bin but what if the deleted data also not found in recycle bin.
                                       
There are lots of freeware and as well as shareware software available in market that claims to recover deleted data from PC, pen drive or even memory cards..Some of them works great and remaining are just scraps.

So First of all how data recovery software works..?
When we delete a file on our computer the first place it goes is to the recycle bin. Emptying the recycle bin doesn’t actually remove it instead of, it only delete a link between our computer file system to deleted file and designates the space that file is using as free space for future use.So,until a new file overwrites that space the original file is present on your hard disk. So The data recovery software only rebuilt the links between deleted data to our computer file system.

• Recover Deleted Data using Recuva: I put recuva at top of the list because its my favorite one.Its a handy simple data recovery software by which we can recover deleted files from our PC, pen drives,memory cards and so on. To recover files  Run the software and select which type of files you want to recover and select particular drive or location and allow it to scan.After scanning it will give you a option to recover all files or selected files from your deleted location.
  
• Recover Delete Data using PC Inspector File Recovery: PC Inspector File Recovery is also a great software built to recover data from FAT and NTFS file systems.Working of PC Inspector File Recovery and Recuva Is almost same.they both scan for deleted data and give us a option to recover them.
     
• Recover Deleted Data using Pandora Recovery: The user interface of Pandora Recovery is about as straightforward.It Supports three kinds of searching modes Browse, Search, and Deep Scan and each has its own description so that you'll know which to choose.   
  
• Recover Deleted Data using EASEUS: EASEUS is also a Free file recovery software to recover 1 GB files free of charge.It recovers files from formatted partitions with original file names and storage paths.It can also able to Recover files from Linux file system partition under Windows.
