RAID 0 data recovery is more difficult than other RAID arrays owing to its lack of data redundancy. Now, in this article, we’ll show you 6 important things you have to know about RAID 0 data recovery.
RAID 0 uses a striping method to store data on the member disks in the array. It’s preferred by multiple IT professionals and businessmen as it can provide users with high speed and improved performance at a relatively low price. RAID 0 does not demand disk space overhead or a complex RAID controller. However, one of the drawbacks of this RAID setup is that it isn’t a redundant array. In other words, it does not provide fault tolerance. One disk failure can destroy the entire array in a jiffy. Thus, from this perspective, data loss in RAID 0, such as corrupt PST data, can be difficult to deal with. Here we’ll tell you 6 must-know things about RAID 0 data recovery
1. Recovery Is Still Possible
As what I mentioned above, RAID 0 doesn’t have fault tolerance. Therefore, many users may mistakenly suppose that RAID 0 data recovery is considerably difficult and even impossible. It is acknowledged that RAID 0 data recovery is far harder than other RAID arrays with data redundancies. But RAID 0 data recovery is still possible.
2. Speed Is Important
Nevertheless, since this type of RAID configuration doesn’t offer any redundancy, the system can be completely crippled if a single disk failure occurs in RAID 0. In this situation, data recovery is highly required. You should speed up resorting to related professionals. Don’t waste any time!
3. Don’t Run Repair or Defragmenter Tools
When a hard disk fails, some users may try to run disk repair tool on it. But, this is not suggested actually. In addition, due to disk failure in RAID 0 will make data broken into fragments. Some may tend to run defragmenter utility. However, to be honest, this operation will not help, but worsen the current case.
4. Don’t Replace with a Disk from another RAID System
Now that a disk fails in RAID 0, you may think about replacing this disk. But you shouldn’t replace the failed disk with one that is stored in another RAID system. The member disks in one array should be in the same architecture. Therefore, it is essential for you to ensure that the disk for replacement is compatible with the RAID array.
5. Require Specialized Knowledge
To recover RAID 0 data demands knowledge of the data order on every member disk and block size. If you’ve recurred to data recovery specialists, they will try to find out the block size. And in order to determine the data order, they will find a copy of a large enough file on the RAID array, from which they’ll use a specialized tool to view the disk content. If it fails, they will proceed to do RAW recovery on a member disk to see the stored images on it. All in all, it demands expertise.
6. Keep away from Amateurs
As mentioned in Tip 5, the RAID 0 is much more complicated than what you think. Hence, if you have no enough knowledge about the RAID 0, you had better not try DIY RAID 0 data recovery. Furthermore, likewise, you shouldn’t trust in amateurs readily. Otherwise, your RAID 0 data may give you a permanent farewell.
