CR0 to CR8, SE25 and SW16 · Croydon
Data recovery, Croydon. A case file and a laboratory run: somebody else owns both, which makes the call hard.
CR is not Croydon. CR3 is Caterham and Whyteleafe, mostly Tandridge in Surrey; CR4 is Mitcham, mostly Merton; CR6 is Warlingham; and CR5 Coulsdon spans four local authorities at once. Norbury, by contrast, is Croydon borough with an SW16 postcode and a LONDON post town it shares with Streatham, which is Lambeth. South Norwood is SE25. CR9, CR44 and CR90 are not places. List the CR districts, call the result Croydon, and you have dropped a large slice of the population. What the borough actually is, is an office centre built on purpose and one of the largest outside central London — 121,000 employee jobs counted in 2024. That produces a particular caller. Not usually the owner of a business but somebody who works in one: a practice manager, an office manager, a finance lead, a laboratory administrator, holding material that belongs to a client, a patient, a regulator or the public, on a machine that has stopped. Superdrug's head office is here. The Home Office's visa and immigration operation moved to Ruskin Square in 2024, which is document-scanning and case-record work at scale. Croydon University Hospital on London Road runs 670 beds and eight theatres. Real Digital International assembles and dispatches healthcare sample kits at volume from Queensway, off Purley Way, where the output is order, batch and dispatch records held to a regulatory standard. Around them sit consultancies, surveyors, accountants and insurance back-office teams whose reconciliations live in spreadsheets no system ever captured. And the borough divides: Thornton Heath and Selhurst on CR postcodes, Norbury on SW16 and South Norwood on SE25 are dense inner-suburban London, while Sanderstead, Selsdon, Kenley and Coulsdon are chalk-downland commuter Surrey in all but name. Ten minutes apart, and both are Croydon. Nothing is collected from either. The media moves by tracked parcel to the Guildford intake lab; nobody is charged to look, and one figure is agreed on paper first.

What Croydon sends in.
Different fault? Try the finder →| What is going on | What arrives from here | Where that leaves you |
|---|---|---|
| A caseworker's laptop that will not finish starting | Client material nobody else holds a copy of | Keep it powered off and post the drive alone |
| An instrument PC that stops part way through | Acquisition software nobody is allowed to patch, writing output locally | The drive comes to us; the instrument stays where it is |
| A back-office PC that has begun clicking | Reconciliations and claim spreadsheets no system ever captured | Off at the wall, and no further attempts to start it |
| A NAS the department bought without telling IT | Plugged in once, filled, and not examined since | It travels whole, in its own case, unopened |
| A server that halted in the middle of a rebuild | Ledgers, payroll and the whole mail store behind it | Power off first, then bay-number each disk before it leaves the chassis |
Before the parcel leaves CR0.
Four from Croydon.
Norbury has an SW16 postcode. Is it in your Croydon?
Yes. Norbury is in the London Borough of Croydon and its post town is LONDON, shared with Streatham on the Lambeth side. South Norwood is SE25, Upper Norwood SE19. CR3, CR4 and CR6, meanwhile, are largely Surrey and Merton, and CR9, CR44 and CR90 are not areas at all. None of it alters anything, since nothing is fetched from any postcode.
How long does a drive posted from CR0 take?
Handed over on a weekday it usually reaches the bench next morning. That examination costs nothing and ends in one figure, put in writing. Logical faults — a corrupt file system, deleted material — are usually finished in a couple of working days. Where the fault is mechanical it runs longer, since a matching donor has to be sourced. You are told which sort you have before you are told the price.
The instrument PC has stopped and the run data is on it. What now?
Cut the power to it and attempt nothing else. Repair utilities write to the disk, and a reinstall laid over a failing one can finish it. A read-only image is made first, the recovery is worked from that image, and the original returns to you unaltered. Where a submission date depends on particular files, name them and they come out first.
How should a NAS travel from a CR0 office?
Ring 0203 0868633 first. A NAS goes into the box whole and still cased; there is nothing to be gained by opening one. Servers and RAID sets go in reverse: take the disks out, write each bay number onto the disk as it comes free, and let nobody work the order out afterwards from guesswork. Include the disk that dropped out, bare like the others, and halt any rebuild before the box is sealed.
Begin here if yours is doing the same thing.
Next door to Croydon, on the same terms
Post it from CR0 or SE25; work starts when it lands.
Take the power off and leave it that way. If the data belongs to a client, a patient or a regulator, say so when you ring, because it changes which files are pulled out first and what the report records. Diagnosis costs nothing; the price is put on paper and waits for your approval before anything billable.
