I’m going to wind up this series with three more recovery mistakes. I’m going to combine two of them since they deal with RAID arrays. However, the first one is a common mistake that many users make because they don’t realize the potential for disaster it brings.
• Saving recovered files improperly – One common mistake made when recovering files is saving them back to the same hard drive or media card. The hard drive may still have unresolved issues and saving the data back to it may cause further damage to the file. The file system may consider the lost data area as free for reuse. Your lost files may be overwritten before they are salvaged. Because of this, it’s better to save the files to a secondary drive, an external drive or other media, including DVDs, CDs or flash media. I’ve seen folks save information to the same drive they are trying to recover from, only to have to bring the drive into our data recovery service for retrieval because the problem became worse.
• RAID errors – RAID is an acronym for “redundant array of independent disks.” Basically, this type of system, usually employed on servers, uses several disks to record data, allowing for redundancy. This is supposed to improve reliability; however, if a single disk fails and is replaced improperly, the data could be damaged beyond retrieval. There are several RAID configurations and each one has its own procedure for disk replacement. Because it can get confusing, many businesses contract a data recovery specialist for server recovery. This brings us to the last mistake. If a specialist is needed, the user must supply all crucial data about the server. That’s why it’s a good idea to keep all service manuals and other pertinent installation documentation. Without this information, the repair could cause even more damage.
Our data recovery engineers are trained in server and hard drive recovery and can help you to find all the necessary information for a successful recovery.
