Tips for RAID 0 Data Recovery
RAID 0 HARD DRIVE:
I have been using a RAID 0 hard drive array for some quick work at home, and all of the data I created today has been backed up to this array. I need to be able to access the hard drives because they are my ‘first base’ while I am doing editing on my work, and so all of the data that is currently involved is on those drives. The problem is that, this afternoon, the computer is reporting that one of the drives has completely failed, so that the RAID 0 array has stopped working. This means that the data I have is trapped within the array, and I can’t access it or recover it onto another drive. Although the computer can’t seem to find the drive now, it is not asking me to do any formatting, or told me that the drive has failed to start. It is just that the folder where the hard drive is usually found isn’t there. I have removed the drive which seems to be causing the problems, and tested it, and the computer programs report that it is ok. I need to recover the data as soon as possible.
HARD DRIVE RAID 0:
I am using a Raid 0 array with a number of hard drives. I have used the RAID 0 configuration for some time, and I thought I could manage it and handle any problems. The main difficulty I am having now started when I tried to do an update to the BIOS. The computer kept pressing me to do this update, and so finally I gave in. It now seems as though I have lost two of the drives. The system says ‘Non-Raid’ drive next to each of the drive folders, and I have not been able to read any information, or see the data stored on the drives, since that time. I ran a TestDisk program which I thought would give me a quick result, but I have not been able to see anything at all.
Tips for RAID 0 Data Recovery
RAID 0 is a great solution for systems that need maximum performance. RAID 0 requires two identical hard drives and a motherboard that supports it. It splits every file that you write in half, sending half to each of the two drives. The advantage is that this offers double the transfer speed. This is known as disk striping. It can be done either by a hardware chipset, like the one that comes with motherboards. If you do not have hardware support, there are also software programs that can perform RAID 0.
While RAID 0 offers much faster speeds, it also has its downfalls. If your system fails, you will need to perform RAID 0 data recovery. Since you are using two different hard disks, with each only containing half of any given file, either of the disks failing will make you lose your data. The RAID 0+1 configuration requires twice as many disks (four in total), but provides redundancy, so a disk failing will not cause data loss. Prevention is the best way to avoid losing information.
Still, if you break your RAID array there are still ways to fix it. Not all failures are hard drive failures. Failures can also be caused by the hardware chipset failing, a bad power supply, or bad drivers. The first step is to figure out what is causing the problem. Make sure that you always replace missing components with the exact same ones if you are trying to recover a RAID partition. For example, if your motherboard or RAID chipset dies, replace it with an identical RAID chipset.
The next step in recovery is to reinstall any missing software and drivers. Again, install the same operating system that you used before. Make sure to install the operating system to a separate hard drive with the RAID drives unplugged, and only reconnect them once OS is installed. Writing anything to a RAID drive before you recover your data can cause complete data loss. Once you have installed Windows, go into your BIOS and make sure that RAID is enabled for your drives. Then install any software side RAID programs that are provided by your motherboard or RAID chipset. This should detect your drives and begin rebuilding the RAID array.
Rebuilding a broken RAID array is easy. If the above steps do not work, there are software suites that can fix broken RAID systems. If none of these work the best bet is to send your drive into a professional repair company. As you can see, RAID 0 is a risky solution and prone to failure. Those who choose RAID 0 have chosen increased performance at the expense of data safety. It is much better to make sure that you have a proper backup plan in place to avoid failure so that you do not have to worry about any chance of data loss. This can prevent you from needing to perform RAID 0 data recovery if the drives should ever stop working.
