Data Recovery Case File · Formatted & Logical Faults · The Install Target

He assumed a folder, got a format — then made exactly one correct decision and stuck to it: touch nothing: the SSD's personal files read out whole from beneath a thin new installer

His enquiry described the trap and then, without quite realising it, described the rescue. Installing Windows afresh on his laptop, he was "prompted to use an external drive from which to install the software." The reasonable, wrong assumption: "stupidly assuming that this would simply create a new folder on a hard drive with the required setup files, I selected an Intel SSD that I use to store most of my personal files." The reality: "instead, the process formatted the SSD, leaving only the Windows reboot files visible." And then the sentence that makes this one of the shortest, happiest files in the volume: "I have not touched the hard drive since, in the hope that most of my data is still there and recoverable." He is right to hope, and this page explains why his restraint — not luck — was the deciding factor: format doesn't erase data, and the single greatest threat to formatted data is what gets written next. By writing nothing next, he preserved almost everything.

The decode: what format really did, and why doing nothing was doing everything right

Format, demystified once more: a standard format — the kind an installer performs to prep a target — writes a fresh, empty filing system over the drive's index. It does not scrub the data field; his personal files did not vanish at the format, they lost their catalogue. "Only the Windows reboot files visible" is precisely that: a small new index listing only the installer's freshly-written files, while beneath it the drive's former contents sit intact but unlisted — present, addressable, waiting for reconstruction. The installer's own footprint is thin: setup files are a small write against an SSD holding "most of his personal files," so the overwritten fraction is minor and bounded.

Why his restraint was the whole game: the honest hero of this page is his inaction. Formatted data lives on borrowed time, and the meter is writes — every new file, every "let me just try to fix it," every reinstallation attempt claims more of the unlisted-but-intact territory. By stopping the instant he understood, and touching nothing since, he froze the drive at its most recoverable moment. That is not luck; it is the single most valuable response to any accidental format, and he executed it perfectly. Owners who keep using a formatted drive overwrite the very files they're hoping to recover; he did the opposite, and this page's outcome is the reward.

The self-blame, waived: "stupidly assuming" describes a genuinely misleading moment — an installer that asks for a drive to "use" and then formats it, when a folder is the intuitive expectation. These files have met that exact trap before, and the verdict stands: the interface earns the blame, not the user. His instinct to stop and ask, rather than improvise, converted a bad moment into a routine recovery.

The recovery: read from beneath the installer

The SSD was imaged write-blocked, and the installer's footprint mapped to its boundaries — a small, bounded region. Beneath it, the former filesystem's structures were reconstructed from their surviving records, and the drive's prior contents stood up: his personal files, folders, names and dates, present exactly as the theory promised. Extraction and verification confirmed the overwhelming majority intact — only the modest area the installer had written over showing loss, itemised honestly. His "most of my data is still there" proved not just hopeful but accurate.

On the bench

One technical mercy decided this case before it arrived: the format had happened across a USB bridge, and consumer bridges routinely fail to pass the discard commands that tell a solid-state drive to clear reclaimed space — so the old volume's cells were never told to empty. The SSD was imaged write-blocked behind the DeepSpar USB Stabilizer 10Gb over that same USB path, the installer's thin footprint mapped, and the former filesystem reconstructed beneath it on the image. His touch-nothing discipline had protected the map; the bridge's laziness had protected the territory; the bench's job was to reunite them, verified.

The outcome

The personal files recovered and delivered verified on new media — a short, clean recovery earned by a short, clean decision. Free assessment, one fixed written figure including VAT, no recovery, no fee. The report's one line of advice was really a commendation: you did the hard part by doing nothing — and a note that installer media belongs on an empty stick, so the next fresh install asks nothing of the files that matter.
