Maybe, many Linux users are faced with a specific condition when the mounted partition can refuse to dismount, when it comes to. Error messages indicating that the device is busy can pop up, maybe that is accessed by other users at the time. But with Linux, you can use some commands to unmount the partition of force. In fact, so that you may not need Linux recovery, these restrictions are necessary when another user is accessing. However, critical conditions may arise when this is not accepted, so you can use these commands. On the other hand, the misuse or simple mistake can make you feel more need for data recovery Linux. • First, find out what processes are running with the device / partition, as with the command: # grep lsof | ‘/ dev/sda1′ Where / dev/sdb1 is the device name. • You receive a command output will show the process of using the device. Just stop the process and then try to eliminate the use # umount / dev/sda1 command. -L option can also be used to remove lazy. This cleaning all refrence to the file system • Suppose now that is mounted on / mnt, then you may have strongly desired process using the following command: # fuser km / mnt Qui-k kills the process and access files – m is the file in a mounted file system or block device. As already said too much, can affect the data, so you better be prepared for any type of mishappening. Be sure to run the commands if you’re unsure of, or use Linux data recovery. Open the files may be lost and programs, access files and after all is done, you can get error. If you are unlucky enough to lose one’s own data, using the Linux data recovery software will be like no other options. Linux recovery software scans the disk and recover every bit of information. Stellar Phoenix Linux Data Recovery is the most reliable data recovery Linux recovery. Software is the product of intellectual effort and can scan the disk using the most powerful scanning algorithms. You can get Linux for the recovery of all files, including system files. The support of archives, including file systems ext2, ext3 and ReiserFS file system.
