This point cannot be over-emphasized enough, as this is the part that can make a recovery either impossible or more expensive.
Different manufacturers of RAID cards, Servers, and NAS systems, program their devices to report errors in different ways. Listed below are some common ways to identify if your RAID array is faulty. If your symptom is not listed below, don’t worry, give us a call 0151 342 8188
Server, PC, NAS or standalone RAID array issues:
- Unusual beeps or messages when booting up the RAID device?
- Is the RAID device completely dead? No life in it whatsoever?
- Has the RAID device become inaccessible?
- Is the RAID device showing errors of missing disks?
- Is the RAID array noticeably slower in handling your files?
- Are your files disappearing?
- Has the RAID device been physically damaged?
- Has the RAID device been affected by a power surge or lightning strike?

Drive Interface types we recover from
Standard RAID Device Issues
Redundant Arrays of Independent Disks (RAID) can fail for several different reasons. The hard drives often fail due to overheating – from poor ventilation – consequently resulting in cooked hard drives (similar to NAS devices). The damage from overheating drives varies, from malfunctioning PCBs, damaged magnetic read/write heads, surface damage on the platters, and many other problems.
Also, the drives can suffer from head crashes, stiction (heads stuck to platters), motor seizure, and firmware corruption. It is, however, unusual for all the disks to fail within an array; nevertheless, it is common for more drives to fail when the array is being rebuilt, due to the extra load placed upon the disks.
Subsequently, the RAID controllers can become problematic on their own, or together with the failing drives, making the entire unit unstable and unusable. RAID systems can quickly become corrupted, as well as suffering physical malfunctions, often creating very challenging recovery cases. Excellent working knowledge of both RAID and file systems are essential for high chances of a successful recovery.
If you want to avoid further data loss at this stage, we recommend:
- Stopping trying to access your defective RAID device.
- Please do not dismantle your device in anyway.
- Please never open the lid of any Hard Drive, they are sealed for a reason.
