The most expensive controllers use an additional battery and non-volatile memory.

A controller failure may both result in losing service data and cause several disks to fail. After such errors, RAID can't restore itself automatically.Ī controller is the element containing information of critical importance which is vital for building a disk array and gaining access to all of the files stored on the disks. Mistakes when replacing one of the disks within the storage system, accidental 'rebuilding' of the array instead of 'restoring' it, disconnecting and reconnecting the disks in a wrong order, incorrect RAID initialization or rebuild - any of these things will certainly result in the loss of information. Reliability of the entire array decreases with every disk which is added to it. For most RAID arrays, the day when one or two disks fail means loss of all information, from all disks within this array. Certainly, server-type NAS or SCSI disks can last longer than their SATA counterparts intended for home use only, but there is no such thing as a hard disk that works endlessly. Recover software or hardware RAID of any type: JBOD, RAID 0, RAID 1, RAID 10, RAID 5, RAID 50, RAID 6, RAID 60, etc.īoth hard disk types, HDD and SSD, have a limited operational life. You can use one of the presets or chose the required data in the damaged array, and RAID Recovery™ will collect the disks together to provide you with access to the data. The integrated constructor wizard helps you recover a failing RAID in a step-by-step mode.

Our product can rebuild the crashed RAID and it lets you copy all critical information from there. It reads all the information about the controller, the motherboard or the software used to create a disk array. This program recovers data from non-operational RAID systems or from disks within such systems. Free Download Hetman RAID Recovery 2.5 Multilingual All Editions | 42.1 Mb
