EC2, EC3 and EC4 · the Square Mile

Data recovery, City of London. A firm's file server, one disk short.

Get the status right or nothing else on this page will land. The Square Mile is not a London borough and never has been: 1.12 square miles run by the City of London Corporation, with a police force of its own that has been the national lead force for fraud since 2006 and runs the National Fraud Intelligence Bureau from within these boundaries. The Corporation's July 2026 factsheet, on 2024 figures, counts 676,000 workers and 24,060 businesses, only 1.8 per cent of them large firms; legal work alone accounts for 55,000 jobs and insurance for 22,000. It empties every night, so the call almost never comes from a kitchen table. At Lloyd's, 1 Lime Street, the underwriting record is the asset — slips, binder records and decades of long-tail claims history on risks where a claim can arrive thirty years after the policy was written. In law it is the document management system and the deal room: the Law Society is explicit that it publishes no retention period, so each firm fixes its own from limitation, from its insurer and from its client care letter, with five years of client due diligence records the only number the regulations fix. Two corrections worth carrying: EC is not the same thing as the City, since EC1N Hatton Garden belongs to Camden and EC1V, up at Old Street and Moorfields Eye Hospital, to Islington, while the Barbican and St Bartholomew's are both here; and Inner and Middle Temple sit within these boundaries as Liberties, whereas Lincoln's Inn and Gray's Inn are in Camden. No counter exists in the City or anywhere else in London. Post it tracked; examining it is free of charge, and the figure is agreed on paper first: cards and sticks at £250 + VAT, multi-disk work at £500 + VAT upwards, and between them the single hard disk at £300 + VAT and a camera recorder at £400 + VAT.

A small NAS under a broker's desk, amber for weeksThe share still opens, so nobody thought to mention itPower it down before another member goes
A USB stick the laptop now wants to formatThe one export of a binder record off a system since replacedLet nothing format it; the stick arrives exactly as it is
Every file on the firm's share renamed, a note dropped in each folderA ransomware incident, and the backup drive was mapped to that same serverTake it off the network first — the ransomware page has the rest.
Packing it and posting it:the shipping form is printed and laid in beside the drive. Cover the outward parcel with tracking and insurance as far as the intake lab; coming home it is paid at our end. The packing detail lives on theguide to packing and posting.

Getting the parcel here intact.

Nowhere to hand it over, here or elsewhereA drive cannot be handed over in the Square Mile, and no public counter exists anywhere in London. The work all belongs to the intake lab, with its imaging rigs and its shelf of donor drives, so it is the parcel that goes anywhere. Posted tracked and insured from EC2 or EC3, it usually reaches the bench on the next working morning.
The record outlives the machineInsurance and law both hold material for longer than any disk was built to last. A long-tail claim can arrive thirty years after the slip was written; a retention period fixed by limitation and by an insurer will see out two or more generations of hardware. So nothing here is hurried. A read-only image comes before any work at all, and what has been read is listed against whichever folders you told us mattered.
Work that may have to be producedWhere a recovery may have to be explained to a regulator or a court, what counts is that the process can be described afterwards. The job is booked against a case reference rather than a client name, the original is imaged read-only and never written to, only the areas the recovery needs are opened, and thirty days after your media goes home the working copy is deleted.
The figure comes before the workNothing chargeable begins until you have the figure on paper and have said yes to it. It does not move after that. Cards and sticks sit at £250 + VAT and multi-disk work — an array, a NAS box, a server — at £500 + VAT upwards, with the single hard disk between them at £300 + VAT. What comes back arrives with a listing to check and a VAT invoice your finance team can reconcile.

What firms in the City ask.

Is there a counter in the Square Mile for handing one over?

No, and nowhere else in London has one either. The imaging rigs and the donor shelves live at the intake lab, so it is the media that moves and you who stays at your desk. Send it tracked and insured. An engineer opens the box on the next working morning, examining it costs you nothing, and the return postage is paid at this end.

The matter files go back further than the server does. Can they come off?

Usually. The Law Society publishes no retention period at all — a firm sets its own from limitation, from what its insurer requires and from the client care letter, with five years of client due diligence records the one number the regulations actually fix — so the period routinely outlives two generations of hardware. One hard disk costs £300 + VAT; a memory card or stick, £250 + VAT. Phones and tablets are not handled.

Client papers are on it. Who reads them here?

Nobody beyond the engineer doing the work. The firm's name is not written on the docket; a case reference carries the job the whole way through. Only the areas of the disk the recovery actually needs are opened, no copy leaves the building, and thirty days after your media has gone home the working copy here is deleted. The privacy policy sets out how long each thing is held.

A disk has dropped out of the set on the file server. Now what?

Cut the power at the socket before anything tries to rebuild, because writing to a set that is already one disk short turns a copyable job into an impossible one. A server or a striped set then comes apart: lift each disk out, mark it with its bay, and post the disks by themselves. A NAS goes the other way — that one travels whole, case and disks together.

Post it from EC2 and it reaches the bench next morning.

Do not power it up again. What the machine was up to when it stopped is worth writing down before you ring, because it shapes the first hour on the bench. The look is free. One figure then follows on paper, and until you have agreed to that figure nothing chargeable is done.
