RAID Data Recovery
RAID protects against one drive failing. It does not protect against two, against a failed controller, or against a rebuild that goes wrong. Those are the arrays we recover.
Failures we recover from
- More drives failed than the array can tolerate
- A rebuild that stopped or failed part-way
- RAID controller failure or corruption
- An array that was re-initialized or reconfigured by mistake
- Drives put back in the wrong order
- Deleted volumes and corrupted file systems
How we recover an array
Each drive is imaged separately, including any that have failed. We then work out the array layout, the drive order, stripe size and parity, and reassemble it virtually from the images. Your original drives are never written to.
Before you do anything
- Do not rebuild or re-initialize the array.
- Do not swap drives around or replace more than one.
- Label each drive with its slot number.
- Send every drive, including the ones marked as failed.
Questions
One drive in my RAID 5 failed. Is the data gone?
No. The array runs degraded on the remaining drives, but it is now one failure away from going down. Back up what you can and get the failed drive replaced.
Is RAID a backup?
No. It keeps you running through a single drive failure. See backup and disaster recovery.
Book a visit or a pickup
Call us or book online and tell us the make, the model and what is going wrong. For IT support a technician comes to your home or office. For a repair we pick the computer up from your door, fix it at our own workshop in Burbank and bring it back. We have no storefront, so there is nowhere to drop a machine off. Outside our area, you can mail it to us.
