Storage Media – Logical Damage
Far more common than physical damage is logical damage to a file system. Logical damage is primarily caused by power outages that prevent file system structures from being completely written to the storage medium, but problems with hardware (especially RAID controllers) and drivers, as well as system crashes, can have the same effect. The result is that the file system is left in an inconsistent state. This can cause a variety of problems, such as strange behavior (e.g., infinitely recursing directories, drives reporting negative amounts of free space), system crashes, or an actual loss of data.
Various programs exist to correct these inconsistencies, and most operating systems come with at least a rudimentary repair tool for their native file systems. Linux, for instance, comes with the fsck utility, Mac OS X has Disk Utility and Microsoft Windows provides chkdsk. Third-party utilities are also available, and some can even produce good results. While most logical damage can be either repaired or worked around using disk repair utilities, data recovery software can never guarantee that no data loss will occur… so with that said, its always best to leave to up to the professionals.
IMPORTANT: Don’t Attempt Software Repairs on Your Own!
You might be tempted to try using all sorts of software and repair utilities yourself. Initiating these types of software repairs to the hard drive, smart phone or removable digital media rarely works and, more often than not, they’ll make your data even more difficult to recover. To the point possibly causing er-reversible damage as to where we can’t even help you. At Protech Data Recovery your data is what matters most. So PLEASE, call us first!
