More and more information ends up being stored on attached storage systems. Remote hard drives with USB, FireWire or LAN connection as well as full-blown multi-disk NAS (Network Attached Storage) devices can keep terabytes of data.

Data Recovery from NAS, USB and Other External Storage Media
Reasons of Data Loss
The Undelete (http://the-undelete.com) have been helping its customers to recover lost and deleted information for almost 7 years. During this time, we answered lots of questions, helped solve hundreds of issues, and delivered tools recovering terabytes worth of information. We have also collected statistics on common reasons leading to loss of data, and numbers on recovery success/failure rates.

Recovering Formatted Disks: Is It Recoverable?
Recovering formatted partitions (disks, memory cards, USB flash drives etc.) is a very special case with multiple “ifs” and “buts” making the result a bit iffy. If your device recoverable after a format? Read along to find out!

SSD Recovery. Does TRIM Destroy Everything?
As demonstrated in a series of articles published earlier in this blog, solid-state disks (SSD) tend to wipe deleted information on their own pace due to the way their garbage collection mechanism is designed. Wiped information cannot be recovered by any means, not even with expensive hardware, and not even by pulling flash memory chips out. It’s gone forever.

How Data Is Recovered
Recovering data from different types of storage media require very different approaches. With a large variety of storage technologies and storage issues unique to certain types of storage media, data recovery from a damaged disk can be a matter of simply pushing a few buttons in a data recovery tool – or an extremely complex endeavor depending on what exactly caused the damage, what type of storage media is concerned, and what the user has done to the disk before resorting to a professional solution.

Is It Recoverable? Signs of Permanent and Reversible Data Loss
In the previous article, Permanent and Reversible Data Loss, we discussed the various situations that can lead to the loss of data. From practical point of view, it is essential to be able to tell one from another. It is very difficult to damage a modern storage device beyond repair (or, rather, beyond the point at which a data recovery operation is still possible). This article tries to give hints as to how particular situations can be successful handled in the most economical way.

Permanent and Reversible Data Loss
In today’s world, information is the most valuable asset. Losing information may cause severe damages, sometimes unrecoverable. This is why organizations are trying to protect themselves against data loss as much as possible by building fault-tolerant systems, employing cloud computing for data storage and implementing complex backup systems. However, sometimes the inevitable happens, and information disappears from the most reliable storage. Understanding the costs and implications of data loss as well as realistically estimating the possibility of restoring the lost data is extremely important in corporate environments.

Redundant RAID Arrays: Not a Perfect Panacea
Designing and implementing the optimum storage system is an often underestimated challenge even in large organizations storing and accessing humongous amounts of information. More often than not, companies implement a single RAID array, considering its redundancy a guarantee of data preservation. More often than not, this is not the case.

Data Recovery: Beyond Software
In the previous article named “When Data Recovery Software Will Not Help” we were discussing situations when software can do nothing or very little. In this guide, we’re looking at ways to handle a situation of a physically failed hard drive containing important information.

Preventing Data Loss: SMART Monitoring Your Disks
It’s always easier to prevent a data loss instead of recovering information from an already failed disk. Today’s storage media, including all magnetic and SSD disks, gives plenty of early warnings to hint you about the need of an urgent backup and an upcoming replacement.
