Being in today’s digital world, data loss is the most painful situation for a computer user irrespective of the cause. No matter which operating system is in the use, the situations, such as sudden power failure, hard drive crash, and unintentional data deletion can never be avoided.
“I formatted my Linux hard drive, but forgot to move some important professional documents. Now, I have installed Windows on the same hard drive. Is there any software that can recover my documents?”
“Is it possible to recover the data lost on Linux platform after moving to Windows?”
Above mentioned are some commonly experienced data loss scenarios; however, the situations could be irrespective of the operating system. Since Linux is quite a sophisticated computer operating system, it is not a preference of home users. After meeting a few data loss incidents, some users even quit using Linux and move to the Windows operating system or a few adopt Macintosh. Some even delete Linux partitions (EXT2, EXT3, EXT4 etc.) knowing the new operating system is not going to use them due to file system mismatch, which results in a huge data loss. However, they do not know that it is still possible to recover the data lost or deleted on Linux. Since Windows installation requires repartitioning the hard drive with either NTFS or FAT file system, data previously saved on the same drive must be shifted to an external data storage media in order to prevent the loss.
However, you must be glad to know that the data lost on Linux can be recovered even after deleting the EXT3 and EXT4 partitions using advanced Linux recovery software based on Windows platform.
You must be curious to know how it is possible as data is no longer available. It is possible because the data deleted from a hard drive was never deleted permanently until you reuse the vacated memory. Every time you execute a data access command, operating system calls for its index entry that is linked to the original location of the data. A delete command only deletes this index entry; however, the data remains intact at its original location and the memory it occupied is marked as ‘available’.
Several commercial Linux recovery software are available on the Internet that are able to perform a thorough scan on the hard drive; however, only a few are capable of finding the deleted EXT2, EXT3, EXT4 partitions.
Once the deleted partitions are found, you can further scan them to recover the data.
