RAID 5, RAID 0 and RAID 1 Servers Errors and Failures:
A Raid 5, Raid 1 or Raid 0 server or rack system can fail for a different number of reasons. Common Raid failures include power surges that damage the raid controller card or the hard drives, Raid rebuilds that have gone wrong, Hard disk failure to one or more disks in the Raid Array, system upgrade that has gone wrong, corrupted data on Raid Array, Firmware upgrade that has gone wrong etc. If you experience any of these problems we have 14 years experience of recovering data from failed Raid Systems including Dell PowerEdge Servers, HP Proliant, IBM ServerRaid, Qnap NAS etc. Give us a call for free professional advice. We can normally diagnose a Raid system over the phone.
Mechanical & Physical Failure of RAID Servers:
Mechanical failure on a Raid server normally means one or more of the hard drives in the Raid Array has had a mechanical failure such as read write head failure, motor failure or potential disk platter damage. Typical mechanical failure symptoms are clicking, buzzing or beeping noises coming from the hard drive. If you have a mechanical failure the best advice is to give our Raid Data Recovery Experts a call for advice. We have 14 years experience of recovering from all types of Raid servers.
Problems Arising from the Rebuild of a RAID Server:
Raid rebuild failures are a common problem. When a disk goes down on a Raid server in most cases the Raid Server or NAS device will offer you the option of replacing the problem disk with a new disk and performing a rebuild. This after all is what raid redundancy is all about. The problem with this is that if the rebuild does not complete 100% then there will be a corrupted dataset. Rebuilds tend to fail if more than one disk has degraded but the Raid server has not picked up the degraded disk yet. We specialise in rebuild failures and have a 99% success rate in recoding and rebuilding data from rebuilds that have gone wrong.
RAID Server Firmware Problems
Electronic and Firmware failure on a Raid Server is common place. Servers with several hard drives running inside it are always more prone than a one disk system of having an electronic failure to one of the hard drives due to the system load. Electronic failures on Raid servers normally means one or more disks have an electronic failure. In most cases it is down to wear and tear of drives as most servers are on 24 x 7 x 365 days a year. Failed firmware upgrades are another problem that IT Administrators have to face on a daily basis. If a Raid System is running slow and if there is a firmware upgrade available do you install the update or not? On a weekly basis we receive Raid Servers in that have had a failed firmware upgrade.
Faulty RAID Controller and Missing RAID partitions:
Raid controllers fail, most of them after 4-5 years. When Raid controllers fail sometimes you can just replace like for like and Raid system will boot up as normal. Sometimes a like for like Raid controller is not available to buy or if you do get an identical raid controller the raid operating system does not boot up. Missing Raid volumes or partitions are commonplace. Operating system boots up fine but the data volume is blank. If you have a faulty raid controller or you have a corrupted volume or partition then contact us today.
