Data Recovery: What To Avoid

Data recovery can help you get your data back, no matter if you lost it to a computer hard drive failure, crash, or due to some human error like deleting or overwriting files by mistake. Another reason for losing data can be power outages or failure in operating of certain software programs. In case this happens to your PC, laptop, camera storage card, mp3 player, USD pen drive, or any dat5a storage device, you must not panic, because you still can have your data recovered, but you should better be following these rules, in order to maximize the effect of data retrieval software or services:

  • Do not run that disk drive anymore. Overwriting files may result in permanent data loss.
  • Do not browse the web for data recovery solutions, and do not attempt to run any software that you may find, which claims to recover your information. You risk to lose it for good.
  • Do not use the regular disk tools such as ScanDisk or Disk Defragmentation. You’ll do more harm than good.

The safest way to getting back your files , be them photos, documents or music, is to use a certified data recovery solution, which you’d get from a trusted source, together with detailed instructions for use. Even better, you can let the specialists do the data retrieval for you. Most of the times, they require payment for their services only if they are successful. As nobody wants to work for free, you can be sure they’d attempt their best to give you your lost data in the shortest possible time.

Disc and Data Recovery

Data recovery is probably an issue that most computer users never think of before experiencing their first data loss occurrence. Then they start thinking and re-assessing the situation, but in some cases it may be too late to change something in the computer configuration. Knowing good data recovery services is like having good insurance for your house: you wish to never make use of it, but in case you need it, then you are grateful you did it.

Let’s recap what happens when you realize your data is lost: you seek for it in the folder where you knew it was stored, then you try to use the search function once, or twice, or even several times before realizing that your precious and important data is not on your hard drive anymore. In that moment, panic starts to appear, you sweat out of the blue, then you start thinking of consequences of your data loss. You start to feel sorry for not doing regular backups as all computer specialists advised you to do, you start to figure out that unexpected really happens and that you were totally unprepared to face it.

If you are new to computers, then you should be aware that your data is never safe, that all drives can break from time to time, and that although there are chances that you get your data back, in some situation data recovery is simply not possible anymore. Data on USB flash drives, or on mp3 players like iPod or any other brands, data on Cds and DVDs are not safer, either. All storage devices are prone to crash one day, therefore you should keep your very important data stored on many such drives and refreshed ev ery now and then. Make backup copies, them backups of the backup copies. Storage drives are now mch cheaper than they used to be not very long time ago. Take advantage of this fact and keep data backups in more places.

You know, data recovery is possible, but data loss prevention is better.

Attempting a RAID server data recovery implies deeper knowledge of the data retrieval software and procedures. This may sound insane, as this is the purpose of a RAID  system, to offer increased data security and to avoid data loss. RAID comes from Redundant Array of Inexpensive Disks, so they are expected to offer backups of vital data of a computers network. However, all devices can get faulty in operation every once in a while, and RAID drives make no exception to this rule. Therefore, instead of blaming it on your IT network manager, you’d better make sure he has all cautionary measures in place to keep your data safe. You need to bear in mind that fault-tolerant does not mean fault-proof. RAID data recovery will be required in case of multiple hard drives failure, to give you only one example of a data endangering situation.

RAID Data Recovery Situations

Regardless your RAID types, be them Mirror Sets or Volume Sets or even Stripe Sets with parity, and regardless the drives manufacturer, RAID data recovery is perfectly possible for any operating system and for all RAID controllers. Spanned and striped systems are very much alike when it comes to lost data retrieval. The data recovery on RAID drives may be necessary in situations like missing partitions, controller failure, corrupted RAID or missing partitions. If one or many hard drives in the RAID array system are physically damaged, it is possible that you may need to make use of data recovery specialists knowledge. You may attempt to retrieve your lost data by yourself, but if you are not sure you know how to do it, you’d better find one of those data recovery companies which have the software and the skills to to the job better and faster than you.

RAID Data Recovery Process

The usual method of recovering data is to mirror the drive volumes, then process the data as image files. Briefly, there is a software which runs and retrieves the data, making sure to reconstruct it wherever retrieving is not possible anymore due to sectors corruption. Such software is proprietary to data recovery companies and it may be better to contract their services instead of trying to buy the software.

Data recovery services are not exactly what we’d call cheap, so this is why you need to evaluate very well your data loss situation before making use of such services. Everybody deletes files from the computer by mistake. Usually, those files go into the Recycle Bin, so it is enough to learn how to retrieve deleted data from there to have your information back. However, there are situations in which data recovery is not possible anymore. Among these, we may mention a case: saving a file you are working on, in Excel, or Word, or other programs, thus overwriting a information that was correct with a wrong one. For such cases, there’s no cure, so your files are forever lost. This is why it’s very important to develop the habit of working on copies of the original files, until you are sure that what you’ve done is correct. Data recovery services do not handle this type of data loss, and most probably the professional staff from such companies will tell you the same thing from the very beginning.

You may consider buying data recovery services in one of the following situations:

  • hard drive crash: if you cannot access your HDD anymore, there’s very little you can do by yourself, so it would be strongly advisable to seek for expert data recovery help
  • hard drive natural disaster damage: if something falls on your computer, do not attempt to switch it on if you notice physical damage to the case; laptops and notebooks are very exposed to be dropped on the floor, so their hard disks may fail to operate after such an incident.
  • the failed drive is part of a RAID array: RAID data recovery is one of the most delicate operations of data retrieval, as you may easily lose your data for good if you don’t know very well what you are doing. This is why, either you need a raid 5 data recovery, or a raid 0 data recovery, or even a raid 1 data recovery, to trust the professionals and seek for their help, be it on Linux or any other computer operating system. The good news in case of a RAID or SAN having only one hard drive failed, the data recovery operation can be done remotely, saving you precious time and money.
