To recover a corrupt boot partition on any type of RAID is very similar to what you need to do on any type of desktop or laptop computer: you must reload or repair the operating system. This is a simple type of troubleshooting and for this, the operating system CD is required. On more modern computers and RAID arrays, instead of having the operating system on separate CD, what you often find is that an extra partition is created on the hard drive which contains the installation files. This partition can be accessed and the installation initiated again if necessary – the effect is usually to reset the computer to it’s factory setting. This will get rid of all the user data you have on the system to so make sure you make a backup of your file before you do anything like this!
This type of RAID 5 troubleshooting is called ‘Simple’ RAIDs. It is a group of disks that are connected together tightly. Data is distributed in a linear pattern on the disk. Data is written a sequential order i-e, first disk is filled and then the text gets written on to the next disk and so on. All this is done by the volume manager, who is the in charge of the RAID.
Let’s see what is a disaster recovery plan to begin with. First there are all types of disasters. A hacker can cause data loss on your server. A computer virus can cause data loss to flat files as well as databases. I know most of you are saying sure I have Norton anti virus to protect me. Are the virus definitions up to date. Is is properly configured? if you do not have some outsourcing firm or in house IT staff then how do you know?
RAID professionals are a type of computer technician with the added benefit of offering RAID support services such as data recovery and server upgrades, an example provider, Recover Deleted Data, http://www.recover-deleted-data.co.uk/raid-data-recovery/, is well known in the United Kingdom and has a decent web site too.
Lost data could be anywhere so the software should be able to search all the possible sources and locations of the missing data. It should also be able to retrieve any type of file which was lost or damaged for whatever reason. It is normal that an accidental pressing from the Delete button, then emptying the Recycle Bin or perhaps a hard disk formats. Lots of people believe that the information is unrecoverable but it is still on the hard disk and you can do data recovery hard drive. It is true that when you open a file on the hard disk, the read and write head accesses the addresses associated with those files and travels over the expanse of the drive to fetch them for you. When you remove data from the hard disk, files that hold addresses to gain access to the information get erased. The information itself still remains until it is overwritten!
So check your backups. This is important. I have been in many offices where they thought their technician had done everything properly and I get the backup in my hand and find out it hasn’t run in months or in one case it was simply not backing up the correct folder or the file was locked during the backups and never backed up. So the last step is the most important one for your office. Make it a rule that at least once a week you are going to check your backup and that it is just as important and making sure the water is turned off when you leave at night and the doors are locked.
