RAID 0 striped sets have no redundancy, so when one of the drives fails it takes the whole set down, but the data is normally still recoverable. All drives are imaged, then the data is re-striped virtually and rebuilt into usable files.
All our RAID recovery jobs get a free diagnostic. We will always quote you one fixed price in writing before beginning any work. RAID recovery starts from £500 + VAT, priced per disk in your RAID configuration, and on logical rebuilds you only pay if we recover your data.
A RAID 0 set simply spreads your data across every disk with no redundancy, so when one disk fails, the entire volume goes offline.
In a RAID 0 set, your data is split across every disk with no redundancy, so when one drive fails, the entire stripe goes offline. Every drive needs to be imaged and re-striped in order to recover any data at all.
A striped set is built for speed but offers zero redundancy. With no parity and no mirroring, the array has no way to rebuild a missing stripe on its own. That's exactly why expert imaging matters.
Even though the disks themselves may be in good working order, a bad controller, bridge or enclosure can take a healthy stripe offline. The disks are fine, but the stripe geometry must be worked out before we can assemble the volume.
Recreating the array, or a firmware failure, can lose the block size, disk order or offset that define the stripe. Get these wrong and the reconstructed data will appear as "garbage". We determine them accurately from the images we create.
Each file is spread across all the hard drives, so a bad sector on any one of them leaves holes in many files. A hardware imager reads around the damaged area to retrieve as much data as possible.
Initialising or reformatting a striped volume in an attempt to "fix" it will overwrite the metadata we need. If this has happened, stop any repair process immediately and turn off the machine.
Since a stripe does not contain any redundant information, every member matters. Any physically failing member is repaired on our head-swap bench first, then all members of the stripe are imaged onto stable media using hardware imagers. Next we identify the exact order of the drives, the block (stripe) size and the offset. At this point we re-stripe the data virtually, as it was originally laid out, and rebuild the file system to extract your files. Your original disks are never written to.
Since RAID 0 provides no parity or mirroring, when a disk fails in a RAID 0 array, every member has to be recovered together. A physically failing drive becomes progressively worse each time it's powered on. If a drive has failed, shut down the system and don't run 'repair' or 'initialise' utilities; once they write over the existing stripe metadata, it can no longer be used to work out the correct configuration for re-striping your data.
We perform striped RAID data recovery from workstations, editing rigs, NAS boxes and small servers for customers and businesses throughout Surrey and west London. Media is posted in to our Guildford location; for other array types, see our RAID recovery and NAS recovery pages, and a general overview of data recovery costs.
We offer a free diagnostic with a fixed price quotation, and on logical recoveries you only pay if we recover your data. Use our online diagnostic to start now, or simply give us a call on our freephone number to get under way.
To get a quote before sending us any equipment, please call us or complete our free online diagnostic. Once you have your quote, post the equipment to us (tracked and insured) or hand-deliver it to our Guildford lab in person.
Sending a drive from a computer, laptop, MacBook, iMac, CCTV/DVR or server? You will need to remove the internal hard drive or SSD and send us just the drive, as we are unable to remove the drive for you. We also cannot recover storage soldered onto a motherboard, such as in Apple Silicon Macs and some thin laptops. Only drives that can be removed from a machine and sent to us can be recovered. If you are unsure whether your device has a removable drive, please call us before sending. RAID, server and SAN drives need to be removed from their enclosure and labelled by bay. For a NAS, send the disks themselves if they are removable, otherwise the entire NAS device. An external single drive should come to us whole, along with its cable and power supply.
