 fsck (for "file system check" in linux) A system administrator can also run fsck manually if they believe there is a problem with the file system. Because running fsck to repair a file system which is mounted for read/write operations can potentially cause severe data corruption/loss, the file system is normally checked while unmounted, mounted read-only, or with the system in a special maintenance mode that limits the risk of such damage. A journaling file system is designed such that tools such as fsck do not need to be run after unclean shutdown (i.e. crash). The UFS2 Filesystem in FreeBSD has a background fsck, so it is usually not necessary to wait for fsck to finish before accessing the disk. The modern and faster ZFS in FreeBSD, FreeNAS and PC-BSD has no "fsck" repair tool; instead, it has a repair tool called "scrub" which examines and repairs Silent Corruption and other problems. Additionally ZFS uses copy-on-write, intelligent data scrubbin...

1: VirtualLab Data Recovery VirtualLab Data Recovery ( Figure A ), which sells for £25, is designed to be an all-purpose data recovery utility. Besides supporting the ual FAT, FAT-32, and NTFS file systems, it supports Mac HFS / HFS+ and even NFS. In addition, it supports data recovery on devices such as USB flash drives and camera memory cards. In my opinion, its most useful feature is the ability to make a sector-by-sector copy of a failing hard drive. This allows you to focus on the recovery process without having to worry about the hard drive degrading further or failing completely in the middle of your recovery efforts. Figure A VirtualLab Data Recovery 2: File Scavenger - Data Recovery Utility File Scavenger - Data Recovery Utility ( Figure B ) is another tool for recovering lost data. Like most disk repair utilities, File Scavenger (which sells for £32) can retrieve data from corrupt volumes. However, the tool’s main emphasis is on recovering dat...
