The test protocol
Height of bad luck for us but perfect condition to illustrate this article, we have been able to "enjoy" a serious failure relegating one of our PC to the state of wreckage or almost. Indeed, for completely unknown reasons it has definitely ceased to function by taking the same time all the data stored on both disks MAXTOR S-ATA I Diamond Plus 9 with a capacity of 80 GB each and only 14 old months. Our disappointment subsided, we used one of these two discs (the second drive had a mechanical failure too serious to the point of not being detected properly by the bios on the motherboard) to test the software to recover data as GetDataBack, Undelete 5.0 R-studio ...
We went even further by adding in our protocol, the human factor, ie by carrying out various operations on other discs test: formatting, repartitioning, suppression of voluntary programs and / or files, fragmentation of files and finally deleting RAID cluster, all with the sole aim to be as close as possible the actual conditions of use of most of us.
For this reason we have used hard drives Western Digital Raptor 74Go as MAXTOR Diamond Plus 10 250GB P-ATA on which we installed Windows XP Pro SP2 and a variety of programs (games, utilities, miscellaneous, office, multimedia, etc ...). For RAID 0, two disks of 160GB Barracuda 7200.07 S-ATA Seagate and mounted in the following machine:
* 2x512 MB DDR 400 2.2.2.5 of Corsair TwinX
* Motherboard MSI K8N Diamond SLI nForce 4
* Map 3D RADEON X800XT PCI Express Asus
* DVD-ROM and DVD-ROM NEC ND-2500A
* Hard Drive Seagate Barracuda 7200.07 S-ATA 200GB NCQ and for the operating system disk and P-ATA Barracuda 7200.07 200 GB in a housing mounted 5 ¼ inch external FireWire 400/USB 2.0 for storage of data recovered.
