How Not To Recover Data on RAID Systems

Data Recovery RAID

There are some frequently-used methods of doing disk recovery on RAID systems which are not that effective and may actually be counter-productive as they can cause you to lose data before you can call in a retrieval specialist. With this type of storage technology, data is distributed across the multiple drives in a number of ways, called RAID levels. It is important to know which data recovery methods do not work here so as to prevent costly mistakes.

Some Of The Things Not To Do If You Need To Retrieve Data

  1. Don't try forcing your hard drive or RAID array to go back online. If you are not sure exactly what the problem is, you may damage the drives. If you use a professional, they will have the tools to assess whether the problem is hard drive recovery, power cable, laptop data recovery, etc. You could end up corrupting the disk array if you are trying to force the wrong driver to go online.
  2. Certain businesses requiring disk recovery mistakenly leave their RAID system on in an attempt to make it reveal the problem. If any of your employees has difficulties, it is best to shut the system right down and call in a computer professional to fix it. DIY solutions are not necessarily the best for all repair problems, and it is also very easy to accidentally over-write your data.
  3. It is never a good idea to reinitialise. It is best not to perform the action twice, once the computer has asked you to start the machine. A hard drive is usually started because of a failing internal drive, or sectors that may contain bad data, or failing heads on a drive which need recovery, among other things.
  4. Don't use the Check Disk utility to ascertain where problems may not even be. When you run Check Disk during RAID recovery or laptop data recovery you may end up orphaning some good files in the process. The orphaned files will then be found and data can potentially be corrupted in the process.

Just about any storage device you use, whether it is a hard drive, a USB memory stick, memory card or some variant of this, there is always the chance that the device/drive can become damaged or corrupted due to hardware failure or general wear and tear. Whenever this happens whatever data you have stored on the drive has the potential to be lost. This also applies to Bitcoins.
