When Your System Fails Use Emergency RAID Recovery

HP PAVILION A610N:

I have an HP Pavilion A610N which is one of a number of computers in my office. I was recently advised by a computer company that I should put some more RAM on the system. This is a well-established local company, so I trusted them, but after they had added the RAM to the computer, the system no longer boots up into Windows desktop. There is a message which says that there is no drive for the Windows OS (Windows-No Disk is the actual message), and the computer says that a disk should be put into the drive. One of my staff removed the RAM installation, but the same thing is still happening. I managed to remove the external hard drive, but I am not able to get to the data which is inside the desktop. This has important business information on it, relating not just to the company, but to employee’s payment slips, tax details, and other confidential information. We need to recover this data before anything else happens to the computer, and we are seeking help with it.

HP PAVILION 610:

I have an HP Pavilion 610, and recently suffered a massive internal hard drive failure which appears to have cost me a lot of data. I have tried several methods of recovering the data from the hard drive, including putting the drive into another computer with a SATA cable attaching it to the motherboard, but the computer will not recognise the hard drive, no matter where I put it. I have attached it to different places in the motherboard, all with no joy. I have also tried using an IDE adaptor in the original location of the hard drive, again with no response. The computer will not acknowledge the hard drive, which means that I can’t get the data off of the drive. Some of that data is very important, and it is essential that it is recovered.

When Your System Fails Use Emergency RAID Recovery

HP RAID data storage systems are continuing to grow in popularity because they have a good reputation for being reliable. While the systems are highly reliable, they are not completely immune to suffering from faults that mean that you could potentially lose your data if you do not have a secondary back up. As RAID storage arrays are not simply external hard drives there are a range of parameters that have to be known and understood before RAID recovery can be attempted. If you need urgent access to your data then emergency RAID recovery carried out by our professional RAID recovery experts can provide you with all of the data that was inaccessible.

The first, and possibly most important, thing that will need to be known about your RAID drive is what sort of architecture it comes from. It is worth noting that no matter what architecture is used, all of the drives from that particular array will be required in order to carry out complete data recovery. If your system is a RAID 0 system then the data will be striped across a number of drives. This means that the data will be partially written on each drive. In a RAID 1 system an alternative method is used that is called mirroring. Complete sets of each data are written to each of the drives within the RAID array. While this is perhaps the most robust way of ensuring that data is not lost in the event of a drive failure, it requires double the amount of storage space of other RAID architectures.

The RAID 5 architecture utilises a more complex approach so that multiple copies of data are not required, but also so that a single drive failure does not lead to all of the data on the drives becoming inaccessible. This is done by striping the data across at least three RAID drives, but also includes parity data so that data from a single drive can be reconstructed from the remaining drives should one of them fail.

While the architecture gives a broad indication of how to go about recovering the data from the system in question, it is nowhere near enough information to be able to carry out a complete data recovery with confidence. Additional information will be required that will include parameters such as the position of the disk within the RAID array, the parity that has been used, the operating system that is used to write to, and access, the disks and the file system that is utilised.

Therefore if you require emergency RAID data recovery your first port of call should be one of our specialist RAID recovery engineers who will be able to talk through your drive issues over the phone and who will also be able to offer you a full diagnosis in the majority of cases. In addition to this our years of experience of data recovery will also allow us to provide you with advice about the best way ahead.
