RAID Server and Array Problems Often Encountered:
RAID servers are often used to allow multiple users the opportunity to access multiple drives at the same time in order to speed up productivity in the small office or offices of a large corporation. With this in mind however problems can occur such as individual drives failing and not allowing the saving of data to other drives in the normal way a RAID server would mirror the data. Also instances can arise when arise when the software built into each drive known as the firmware can fail or the RAID controller card may fail. We are experienced in dealing with all of these problems as well as helping old and new clients when it comes to rebuilding a RAID device after an unsuccessful rebuild
RAID Hard Drive Hot Swapping Failure:
The principle of hot swapping is a simple but effective one. Whilst the RAID server is powered on and with users still connected you can remove a faulty drive and replace it with a new functioning drive which will then be populated with a mirror image of the data that has been saved whilst the drive was out of commission. Although a large percentage of hot swaps work without incident there are some that do not and the results can reach from a slight loss in data (perhaps a few minutes) to a complete loss of data (everything continued on the mirrors). To this end we at www.leedsdatarecovery.co.uk are on hand to help you should your hot swap fail or work but with a loss of data. Using sophisticated recovery software and an extensive knowledge base we are sure to be able to help you restore you missing data.
RAID Server Rebuild Failure:
RAID server rebuilds are not something that any IT employee wants to carry out unless it is absolutely necessary to do so. Although RAID rebuilds are often successful occasions can arise when the rebuild is only partially successful or is successful in the sense that all drive function but no data is accessible. Unlike a hot swap the rebuild of a RAID server means the powering down the system, getting all members to log off and taking time and patience to identify the malfunctioning drive(s). A rebuild may seem as though it is going well when powering the RAID back up but the software overseeing the remounting of the drives may report errors such as unreadable storage devices or devices that are unresponsive to requests from the controller. We here at www.leedsdatarecovery.co.uk are well versed in the problems that can be encountered with a complete RAID rebuild and are on hand to help you through the process as well as ensuring the data on your drives has been recovered safely.
RAID Firmware Upgrade Unsuccessful:
RAID Firmware is important without a doubt. The program which many people have heard of but never encountered is designed to send instructions between each of the drives in the array and also to the controller card should the array be controlled via an external computer. Failing firmware can lead to a breakdown in communication between drives, RAID boards and controller cards. If this happens then the RAID array is unlikely to allow access to any data saved on the disk as well as potentially losing any data that has been saved to the array before the problem was discovered. Firmware failures in RAID devices are something we at www.leedsdatarecovery.co.uk are more than aware of and have years of experience dealing with.
RAID Partition and Controller Card Issues:
RAID controller cards are often to be found in external PCs that control the RAID array and allow the access to it from other computers attached to the network. A failing controller card can be identified when one or more members of a network report that they cannot access or save files or data to the array through the controlling computer. The controller card may be faulty and as such may not allow for the correct routing to individual drives in the array that then share out the data to produce a mirror image on all RAID drives.
