The topic goes about Dynamic Disk Recovery and all the things connected with it. If you utilize embedded Raid controller, it can demand the Raid array recovery facilities. Let's look at the example. After you have equipped a Raid array on a built-in chip set controller from AMD SB 600. You were glad because all the things worked without any problems, but all of a sudden the moment of your PC renewal came. So, you stopped your choice on the Intel Core processors. You've settled what main board to select and you find there a built-in ICH9R controller, you have replaced your hard disk drive, but Raid array isn't identified yet. There're two ways out obtainable for users:
1. There's a way of getting new hard disks and making a new Raid array on them. In this situation you would have to transport the old info to new hard disks and spend a great amount of time to restore previous Raid array.
2. And you may select to go to some “data restoration lab” where the specialists will restore your Raid array for some money and during the short term. Or you can use specialized Raid recovery software. But the difficulty would not just exist in case when people use external Raid array, because in this situation persons need only to transfer a controller with hard disks. One more difficulty is that the built-in Raid controllers that are accessible in the market, are semi-hardware. And this kind of controllers may restore only the arrays 1, 0+1, 5 and they don't use some other means of data restoration.
The way of “mirroring” can assure protection. Some people say that if you would not use stripe (Raid 0), you're certainly protected from Raid arrays and data recovery. But in case of electricity problems, driver difficulties in operating system, virus attacks one can lose 2 hard drives at once and it will not be saved by any mirroring. But what is the settlement of this type of difficulty then? You may just restore the data from Raid array or restore the Raid array in whole. The cleverest point you may do here is to switch off your personal computer and take it to a file restoration specialist or to receive a professional program. Only making these strides you will get an ability to protect and restore your data from Raid arrays. Read the rest of this entry »
