There is lots of info for people who are interested in RAID recovery. The utilization of built-in Raid controller often needs Raid array restoration facilities. Let us take an instance. You've installed an embedded chip set controller from AMD SB 600 with the installed Raid array. You're happy because all the things worked without any difficulties, but suddenly the moment of your personal computer refreshment has come. So, you made your selection on the Intel Core CPU. You've selected a main board, but there's a built-in controller ICH9R, replaced hard disk drives and Raid array can't be determined. You can select one of 2 possible ways out:
1. You may buy new hard drives and create absolutely new Raid array and transport all files from the old machine to a new one that needs lots of expenditures and long period of time to recover a preceding Raid array.
2. And you may choose to go to some “file restoration lab” where the specialists would recover your Raid array for some funds and during the little term. Or you can use professional Raid restoration software. But the problem will not just exist in case when persons use external Raid array, because in this situation persons need only to transfer a controller with hard disks. The other problem is semi-hard controllers that overfilled the market these days. Such controllers can restore only 1, 0+1, 5 Raid arrays and the other means of data recovery aren't available for them.
The utilization of “mirroring” as assurance of safety. There's an opinion that the utilization of stripe (Raid 0) deprives people of file restoration and persons who don't utilize it are really secured from the Raid arrays restoration. But in situation of electricity problems, driver problems in operating system, virus assault one can lose two hard drives at once and it won't be saved by any mirroring. And what should you do in this situation? The only point you have to do in this case is to strive to recover all the files from Raid array or restore your Raid array in whole. The best point that may be made is of course taking your computer to a data restoration specialist or buying professional Raid recovery program. You can protect your data only using these pieces of advice and without inventing self-made restoration deeds. But you should know that this is not a simple thing to restore hard drive with hard problems. You can find lots of raid 5 recovery programs on the web these days.
The settings of main board's BIOS came to zero. It also can happen that a battery of a main board disburdens and neither BIOS nor operating system may see Raid controller. It can happen in situation when BIOS has default parameters. There you can confront the situation when insufficient individual will come, reinstall operating system and say that the data couldn't be restored. You should bear in mind that in such situations you are to entrust Raid array recovery only to a qualified professional. Such individual would take your personal computer, see the trouble and settle it down. That will take approximately some minutes of your and his time.
Data restoration from Raid 0 array. Programmers claim that if 1 of the hard disks would fail during the utilization of raid array all the data would be lost. It is true. But if you won't strive to restore it by yourself than practically in 100 percent of situations all your info would be recovered. And after that you would buy a new hard drive and restore your Raid array there. So, if you're interested in Linux raid you're to go on the web search.
