OWC external hard drive recovery. Mac-market boxes, often with drives you fitted yourself.

An OWC unit is recovered here for £300 + VAT for a single drive, and from £500 + VAT for the Dual, Quad and ThunderBay units. OWC's enclosures are sold empty as often as filled, so the drive inside is whatever you fitted, and the ThunderBay and Elite Pro Quad are RAID sets, usually software RAID on a Mac or a hardware RAID on the Quad, that have to be read as sets. The Oxford and ASMedia bridges in the older units fail before the drives do. 3–4 days at the bench.

Packing it and posting it: leave the drive in its own case, unopened, and do not take the drive out of a WD My Passport or My Book, because the board it is fixed to holds the encryption key. Wrap the whole unit in bubble wrap inside a box with nothing able to move, send the mains adapter with a desktop drive, insure it for what the files are worth rather than the price of the drive, and use a tracked service. The posting address is not printed anywhere on this site; it arrives by email in reply to the form, with a booking sheet to print; the sheet inside the parcel is what matches it to your enquiry when it is opened. Or hand the sealed parcel in at the nearest of ten drop-off points, your name on the outside and the sheet inside; say where you are on the form and it comes by email. We pay the postage home either way. The whole of it is written up on the guide to packing and posting.

01

Logged the day it lands, and the first look costs nothing Free

A case number goes on it the day the parcel is opened, and an engineer settles what has actually failed before anything else happens. A drive that clicks or beeps is not powered again; one that spins is read on our own imaging equipment, never in a computer that will retry and time out and retry. Back to you come two things together: a straight note of what is liftable and what is not, plus one figure, fixed and written down. Accept it, or decline and owe us nothing.

Nothing to pay for lookingA single figure, put in writingNo hopeful power-ons
02

The enclosure and its board

Every external drive is two things: the drive, and the USB board that talks to it. The board is checked first, because a failed bridge, a snapped socket or a dead regulator is the whole fault on a good share of jobs, and because on WD's encrypted drives the board holds the key. Where the drive itself has stopped, it comes out of its case onto the bench.

03

The mechanics, in clean air

Stuck or failed heads are replaced with a matched set from a donor, seized spindles freed, and firmware faults corrected in the drive's service area from the terminal. The drive is not repaired to be used again; it is made to read once, in a single careful pass, and that pass is planned before it begins.

04

A full image, then the volume

Nothing is worked on live. The whole drive is imaged once, head by head and weak areas last, with reads timed to what the platters can stand, and the file system is put back together on the image. Encrypted volumes are unlocked there too, with the original board's key or the password you supply, and never on the original.

You see the file list before you pay

What was recovered is listed for you first, and only then does a bill exist. Approve the list and it is invoiced; turn it down and it is not — and where nothing has come back, most jobs carry no charge at all. Recovered data travels home on fresh media bought in for your job, with the postage at our end. Your case is not closed until you have opened the files on a machine of your own.

From the bench

  • Label the bays before a drive comes out. A striped set put back in the wrong order will not assemble.
  • A rebuild is the most dangerous button on the box. On a degraded set it writes across every remaining member. Stop it and image first.
  • Send the box with the drives. The controller's configuration lives on its board, and on some units so does an encryption key.

What helps, and what harms.

Do this much first

  • Power it down and leave it down
  • Write each bay number on its drive if you remove any
  • Send the box, its power supply and the drives
  • Tell us the RAID mode if you know it

What sets us back

  • Rebuilding, resyncing or re-creating the array
  • Swapping drives between bays
  • Initialising a drive that shows as new
  • Running a repair from the unit's own software

Questions answered before you commit.

My ThunderBay RAID will not mount. Is it four jobs?

One job, four drives, from £1,250 + VAT: every member imaged, the set rebuilt from the images, and the volume mounted from the rebuilt set.

Which drive is inside a OWC?

It varies by model and batch: Seagate, Western Digital or Toshiba on anything recent, sometimes Samsung or Hitachi on older units. The free look identifies it, and donor parts are matched to the drive, not the badge.

What does it cost?

£300 + VAT for one drive after the free look, fixed in writing before any chargeable work. On most jobs no data means no bill.

How long does it take?

3–4 days at the bench after the free look.

Begin here if yours is doing the same thing.

Nothing gets worse while it is unplugged.

Looking at it is free. Back comes a list of what opened and what did not, together with a single price to finish, set down in writing while you are still free to say no. On most jobs an invoice only follows the data. Until that list reaches you, leave the drive unplugged.
