After accidentally formatting his 500GB external, a South Yorkshire customer set about rescuing it himself. "I have tried many software's to recover my Pictures, Music and Videos", he explains, only to end up "only able to recover 12GB of data that cant even be seen, just information in writing" — from a drive that "had around 470GB of data". His question could not be plainer: can all of it come back? Twelve gigabytes of unreadable fragments from consumer tools is not proof the data is gone — it is proof those free tools hit their ceiling, and possibly a sign that the attempts themselves have begun to cause harm.
| Media | 500GB external hard drive, accidentally formatted, then subjected to multiple consumer recovery tools — roughly 470GB of mixed media originally present, only fragmentary unreadable output obtained |
| Reported situation | Accidental format of a nearly-full external · several free recovery utilities run against it · about 12GB recovered, none of it openable · original contents photographs, music and video · a hope of recovering everything |
| Fault class | Post-format logical recovery complicated by repeated DIY tool runs — the concern being not only the format but writes those attempts may have made to the drive being recovered |
| Equipment used | Drive imaged immediately under a hardware write-blocker, taking all further work off the original to stop any additional harm · the image assessed for the format type and for evidence of writes from prior recovery attempts · the pre-format filesystem structures rebuilt in R-Studio and UFS Explorer where they survive · deep signature-carving of the full data area for photographs, audio and video · results validated by rendering, corrupt and clean files separated honestly |
The poor result points at the tools, not the drive. Free recovery utilities are shallow by design — they carve for common file signatures and give up on anything fragmented or complex. Recovering 12GB of unusable fragments from a 470GB drive is a classic under-powered-tool outcome: the data is very likely still there in bulk, and the software simply could not assemble it into whole, openable files.
"Can't even be seen, just information in writing" describes a specific, fixable failure. That sounds like files carved without their structure — raw data with no valid header or index, so nothing will open them. Proper recovery rebuilds the filesystem's own records to restore files intact with their names and organisation, rather than dumping headerless fragments a person then cannot use. The difference is method, not luck.
The real risk in what he did is the writing, and it must be said plainly. Some consumer tools install onto, or write working data to, the very drive being recovered — and every such write lands on the free space where the formatted files still live, potentially destroying them. Repeated attempts multiply that danger. This is precisely why the first professional step is imaging the drive and never touching the original again: to freeze whatever survives before anything else is risked.
Recovering "all of it" depends on two things, stated honestly. First, the format type — a quick format leaves the data area intact and recovery prospects high; a full format that overwrote the surface is far more limited. Second, how much those DIY tools wrote back to the drive. Both are read from the image at assessment, and the realistic ceiling is set by evidence, not by hope — a nearly-full drive formatted quickly and not overwritten can recover very substantially, but a promise of "everything" before assessment would be dishonest.
His media types are favourable, which helps the outlook. Photographs, music and video all carry strong, recognisable signatures that carve well, and deep signature analysis on a full write-blocked image reaches far more than a free tool's quick scan. Where the filesystem structures also survive, those files come back organised rather than as an unnavigable heap.
The honest deliverable separates the good from the damaged. Rather than a vague count, the result is a validated listing — files that open correctly distinguished from those the format or prior attempts corrupted — so he sees exactly what was recovered and in what condition, before anything is paid.
The drive was imaged immediately under a hardware write-blocker, moving all work off the original. The image was assessed for format type and for signs of writes from the earlier tools. Pre-format filesystem structures were rebuilt in R-Studio and UFS Explorer where they survived, and the full data area deep-carved for photographs, audio and video. Every recovered file was validated by rendering, with clean and corrupt files separated in an honest listing.
Original preserved by imaging, format and prior-write impact assessed, filesystem rebuilt and the data area deep-carved, with a validated listing of what opened cleanly. Free assessment, one fixed written figure including VAT; where recovery is not possible, nothing is charged. The decode: 12GB of unreadable fragments meant the free tools hit their ceiling, not that your 470GB vanished. Proper recovery rebuilds files whole instead of dumping headerless scraps — and the urgent lesson is that those DIY attempts can write over the very data you are trying to save.
Stop running recovery tools on the drive at once — many write to the disk they are scanning, and each attempt can overwrite the formatted files you still hope to recover. Fragments that "can't be opened" usually mean shallow tools carved data without its structure, not that the data is destroyed. Set the drive aside untouched; proper recovery images it first and rebuilds files whole. And be wary of any promise of "everything" before assessment — the format type and prior writes set the real ceiling.
