How it was lost · fire or flood

Exeter water and fire damage recovery. Wet or burnt: don't dry it, don't power it.

Most soakings do not touch the platters, and data leaves the fires that destroy the equipment surrounding it. What finishes drives off is what happens next: the hopeful on/off, the radiator, the bag of rice, and waiting, for corrosion begins within hours. Seal it in a bag and obtain a quote first, either via telephone or through the form, then please send your item to us from Exeter today or bring it into our intake laboratory located in Bristol (Monday to Friday, 9am to 5:30pm, no appointment needed).

The errorWhat it usually meansStep one
Dead ever since the water got inWater has destroyed your PCB, but there is almost certainly no damage to the platters, as they reside within a sealed environmentGet a quote first, then send it wet, with the drive bagged
Trips the plug socket or PSU when connectedYour board is shorting out each time you try this; it's pushing current through the preamp of your drive's headDo not attempt it again
White or green fur growing on the contactsCorrosion is active. It will continue to spread while you waitEach hour matters
Pulled from a fire, casing intactThe platter chambers are sealed, and burnt boards can be replacedTreat it very delicately. Never remove the seal
Soot around the connectors or breather holeGrime, abrasives and acids kill the moment the platters spinNothing gets cleaned, and nothing gets turned on
Went into the seaSalt water will attack the magnetic layer on the disk directly; that's the very worst type of water you could getJust keep it wet and sealed up
Posting it to us: get a quote first, by phone or with the form, then please use a traceable (tracked) and insured postal delivery method to send your device to our intake lab in Bristol; the return is paid for by us. Alternatively you can drop your item off there yourself, Monday to Friday, 9am to 5:30pm, with no appointment needed. An engineer will talk you through how to pack your unit when you call to obtain the quote. More information about sending your items can be found on the contact page.

Water and fire: what survives, what doesn't.

What water does to plattersAlmost nothing. Recording surfaces remain in their sealed state and therefore survive immersion well. It's the electronics that get hurt (board, contacts, connectors), and all of them can be cleaned or swapped out.
What heat does to boardsIt burns them. But the platters hardly even know about it. A burnt PCB is swapped for one from another unit, provided your drive's own ROM chip makes the jump across.
Salt water versus freshA freshwater environment will cause slow corrosion; however, a marine (saltwater) environment is an entirely different creature, as chlorides actually attack the magnetically sensitive coatings on your media. A drive recovered from the water at Exmouth travels fully enclosed and still wet, without drying.
Soot and smoke residueFire's second act: acidic particulate (grit) forms a film through all gaps. Once a contaminated drive is spun, it sands down its own surface (platter), so all of the decontamination has to occur well prior to the application of power.

The recovery, one stage at a time.

01

Booked in, assessed for nothing Free

Your device will be logged under its own case number on the day it comes into our lab. The engineer who works on your device identifies the problem with it, clearly states what we think has a good chance of coming back and provides you with one fixed quote. There are no charges for this assessment; there is no obligation for you to do anything; and paid work does not begin until you authorise us to start.

The look is freeA single quote, in writingNo obligation
02

Stabilise before anything

Recovered wet media are transported wet (sealed in a plastic bag). Dry out any recovered wet media and the soluble salt will precipitate onto the exposed surface(s). Recovered fire-damaged media are received packaged and have not been disturbed or opened since recovery; the soot remains intact.

Wet stays wet in transitBagged door to door
03

Strip, clean, rebuild

The corrosion has been removed, the contact points have been cleaned and a donor PCB has been put in place which includes the original ROM chip for your drive. The new electronics can serve the uncorroded (and thus still usable) platters.

Contacts brought backOriginal ROM transplanted
04

Image on the first window

As soon as the cleaning process is completed, the chemical reaction begins to occur once again. Therefore, the drive is immediately imaged. Once an image of the drive is created, the original will never be run again.

Imaged as soon as it's safeOriginal retired after the copy
05

Watched back, verified, returned

You have access to a complete list of every item recovered from your device, which you approve prior to any fees being applied. The files will be returned via new media (brand new) with the return postage paid by us, and the case remains open for as long as it takes to confirm that all the files open properly on your own machine.

Opening checks at the bench

  • Hours (not days): corrosion is already forming on a wet board. This should be done today, not next week.
  • One power-up with dampness will double the damage to your board (shorting) and the head's preamp (taking a direct hit), essentially converting a simple clean into a full head swap.
  • Salt water is the most cruel: its chloride attacks the magnetic layer of a drive itself, so any boat or beach job that needs to reach us must arrive in a sealed, wet condition as soon as possible.
  • Fire destroys in a merciful manner: first boards and plastics, then platters last. We rebuild around the one part that matters (the platters) with cheap parts.

All cases for water and fire show the exact same pattern: the result is mostly determined before the parcel gets to the bench, based upon whether the power button was ever pushed, and how fast it travelled. Drives which were never turned on and were posted the same day routinely recover. The one phrase which gives us cold sweats is 'I just tried it quickly': on a wet PCB, that one try is enough to make a board repair into a head repair as well.

Fresh from the casebook.

A burst pipe over the home office; the drive arrived in a sandwich bag

Full marks to the owner: no power applied, bagged and still damp, and posted first thing. On the bench we cleaned up the contacts, put a donor board in with the original ROM, and had the whole drive imaged within one week; twenty years of family photos were back, all good.

Before it leaves your hands.

Do

  • Cut all power, and do not restore power to the device, nor to its PC or NAS home
  • Seal the drive in a plastic bag. If it's wet, leave the drive as is; do not attempt to dry it
  • Tell us what type of water you are working with: mains water, flood water or sea water
  • Act quickly: the rusting will continue whether you like it or not!

Steer clear

  • Using rice: it cannot get through a sealed enclosure, and the time spent waiting for it to work feeds the rust
  • Hairdryer, oven, radiator, airing cupboard etc.
  • Powering up the drive as a test, just to check if the disk is 'OK'
  • Removing soot from the drive, or removing its casing

Straight answers from the bench.

Can a drive that's been under water be recovered?

Usually, as long as you didn't turn it on when it was still wet and you get it into a lab quickly. The water causes most damage to the electronic circuitry and generally doesn't harm the platters. And the electronics can be replaced.

Will rice dry out a wet drive?

No. There is no way that rice has an effect on sealed electronics. It cannot get inside because it's sealed. Also, rice produces starches and dust, and all the while there is corrosion going on, eating your equipment.

Will a hard drive survive a house fire?

Yes, frequently. The platters are housed in a sealed metal box and a burnt PCB (printed circuit board) is easy to replace. Your real concerns are heat warping the platter(s) and soot getting inside: keep the drive enclosed; do not wash it; do not power it.

Should I let it dry out before sending?

A strange piece of advice, but correct: no. Letting things dry out allows the dissolved minerals and salts to form crystals as they spread over all the exposed surfaces. Leave a wet drive sealed in a bag; if it has been submerged in salt water, keep it wet until it's on our bench.

Whatever the fault, leave the power off.

Every time a failing hardware component is powered back up, there is additional lost data. First open a case with us: the inspection (look over) is always at no cost, whichever way it goes.
