When a partition vanishes — a drive that suddenly shows as unallocated, an external that asks to be formatted, a whole volume gone from Windows — it feels like everything on it has gone with it. It hasn’t. A missing partition is a damaged map, not lost data: the files are still sitting on the drive, and the fix is to find the partition again and rebuild it. We recover lost and deleted partitions for people across the UK — post yours in or drop it at our Belfast lab.
The partition table that points to your data is damaged — the data itself is intact, and the map can be rebuilt.
A drive is divided into partitions using a small partition table at the start — a map that records where each partition begins, how big it is, and what file system it uses. Your files aren’t in that map; they’re spread across the drive, and the map just tells the computer where to find them. So when the partition table is damaged, deleted or corrupted, the computer loses its way — the partition ‘disappears’, the space shows as unallocated, or the drive asks to be formatted — even though every file is exactly where it was.
That’s the reassuring reality: recovering a missing partition is usually a matter of finding the partition again and rebuilding its entry in the map, or reconstructing the file system, so your files reappear intact. It’s a logical problem, not a physical one, which is why it’s so often fully recoverable — provided nothing new has been written over the space in the meantime.
Deleted in Disk Management or a partition tool. A partition removed by mistake — the entry is gone from the map, but the data behind it remains until overwritten.
A resize, merge or repartition gone wrong. Partitioning software interrupted mid-operation, or a resize that failed, can leave the table inconsistent and a partition unreachable.
Drive suddenly shows as unallocated or ‘not initialised’. Corruption of the partition table — the whole drive appears empty, though the data is intact behind the damaged map. Don’t initialise it if prompted.
A partition showing as RAW or asking to format. The partition is found but its file system is corrupt — the files are still there (see file corruption), and formatting is what buries them.
Malware, a bad update, or a failing drive. Any of these can damage the partition structure. If the drive is also misbehaving, treat it as a failing drive and stop using it.
Don’t create a new partition in the unallocated space, and don’t initialise the disk when Windows offers to — both write a fresh, empty structure over your data. Don’t format a partition that shows as RAW or asks to be formatted — the files are still there behind the corruption. Don’t run partition-repair tools that write to the disk, and be wary of ‘fix it’ utilities that rebuild the table in place, as a wrong guess can make recovery harder. The safest approach is to stop writing to the drive entirely and let the partition be recovered from a copy, so the original is never altered.
We work from a copy of the drive, never the original, so nothing is written to your data. We scan the whole drive for the signatures of lost partitions — the tell-tale start markers and file-system structures — to locate exactly where each partition began and ended, even when the map is gone entirely. From there we rebuild the partition and its file system, bringing your files back with their original names and folder structure. Where a partition can’t be fully reassembled, we fall back on file carving to recover the files directly by type. If the drive itself is failing, we image it first with the appropriate drive recovery, then recover the partition from the image.
It starts with a free diagnostic: we assess what’s recoverable and give you a fixed written quote, with a file listing to check, before any chargeable work. On most jobs it’s no fix, no fee, and pricing is per case. It’s all done by post or drop-off, so you don’t need to be nearby — send the drive or device in from anywhere in the UK or Ireland, or drop it off in person.
Usually, yes. Unallocated space almost always means the partition table — the map to your data — has been damaged or deleted, while the files themselves are still on the drive. We scan for the lost partition, rebuild it and its file system, and bring your data back. The important thing is not to create a new partition or initialise the disk in the meantime, as that overwrites the data.
Usually, yes — if you act before the space is reused. Deleting a partition removes its entry from the map but leaves the data behind it intact until something overwrites it. Stop using the drive, don’t create anything new in the freed space, and we can locate the deleted partition and rebuild it with your files intact.
Often, yes. An interrupted or failed resize or merge can leave the partition table inconsistent and a volume unreachable, but the underlying data is usually still present. We reconstruct the correct partition layout and file system from a copy of the drive. Don’t run further partition operations on it, as those can complicate the recovery.
The partition is usually still there — its file system has become corrupt, which is why it shows as RAW or asks to be formatted, but your files remain on it. Don’t format it. We image the drive and rebuild the file system from the copy so the partition and its contents come back.
With caution. Some tools rebuild the partition table in place, and a wrong guess written back to the drive can make recovery harder. If you do try software, never let it write to the affected drive, and don’t save results back to it. For anything important, or if the drive is also failing, it’s safer to have it recovered from a copy so the original is untouched.
No. Our lab is in Belfast, but lost-partition recovery is done by post or drop-off, so we work with clients right across the UK and Ireland. Send the drive in with insured, tracked delivery, or drop it off in person — the service, diagnostic and pricing are the same wherever you are.
Stop writing to the drive, don’t create a new partition or initialise the disk, and get in touch. We’ll assess what’s recoverable for free, give you a fixed quote before any chargeable work, and rebuild the partition from a copy so your original is never touched.
