Failed HP Server?
Emergency data recovery.

If your HP server has crashed, or your RAID storage has failed, we have the skills to get your server back up and running. Quickly. Our HP Server Recovery engineers recover failed hard disks, failed or corrupt RAID arrays, and even from severe data loss caused by power surges. If you’ve already attempted recovery and it has failed, you should contact a specialist data recovery company.  It is critical that the hard drives are securely backed up before further recovery continues. Even if you have a  corrupt file system that means the server will not boot, we’re in a position to recover your server. Right away.

If your HP server has a failed RAID array, and you have tried a hot-swap disk that did not work, please do not continue.  Of all the totally unrecoverable RAID arrays we encounter, the commonest cause of data loss has been user error.  When we receive a server or storage that has not had any recovery attempts, we almost always deliver a totally successful recovery.

Emergency Data Recovery We can usually start recovering and extracting your data within one hour of making secure backup copies of the drives from your RAID array.


When we receive your Server or the RAID disks, we’ll immediately make backup clone copies of the original drives.  We never work from the originals.  We’ll diagnose the server the minute we receive it.  We will keep you updated throughout the recovery process, and where possible, we can start sending you the most urgent data before the process completes.

Crashed HP Server: causes of failure

• Hard drive failure – or multiple drive failure
• RAID controller failure
• RAID rebuild failure
• Firmware update failure or firmware corruption
• Power surge or power spike
• IT Admin or user error (the leading cause of permanent data loss)
• Incorrect drive substituted for the RAID rebuild process
• RAID array reinitialisation / reinitialization
