Deleted Data Recovery
Recovery of accidentally deleted files from hard drives, USB drives and memory cards — with realistic expectations set by how each storage type actually erases data.
When a file is deleted, it is typically marked as free space rather than immediately erased — the underlying data can remain physically present and recoverable until it is overwritten by new data. This is generally true for hard drives, USB drives and memory cards, but SSDs are a significant exception: TRIM can proactively clear the flash pages behind a deleted file, which can make recovery impossible or severely limited. DiskAnalyst assesses the storage type and usage history before saying what's likely recoverable.
Common Causes of Failure
Straightforward Deletion
A file deleted from a drive that has otherwise seen little use since — generally the most recoverable scenario.
Emptied Recycle Bin
Files removed from the recycle bin or trash remain on the drive in the same way as a direct deletion, until overwritten.
Deletion After a Software or OS Error
A crash, failed update, or software fault deletes or hides files without physical damage to the drive.
Deletion Followed by Continued Use
The more a drive is used after deletion, the more likely the original data has been partially or fully overwritten.
SSD Deletion With TRIM
On an SSD, TRIM may already have cleared the flash pages behind a deleted file by the time recovery is attempted — a storage-management limitation, not a sign the recovery process has failed.
What We Handle
- Accidentally deleted files and folders
- Emptied recycle bin recovery
- Deleted files after a software or OS error
- Recovery from HDDs, USB drives and memory cards
- SSD deletion cases, with TRIM-related limitations explained upfront
- Deleted files after a partition change
Common Signs & Failure Scenarios
Our Recovery Approach
-
1
Storage Type & Usage Assessment
We start by understanding what type of storage is involved and how much it has been used since deletion — both materially affect what's recoverable.
-
2
Controlled Imaging
Where appropriate, we work from an image of the drive rather than continuing to read and write to the original.
-
3
File System Reconstruction
Deleted file entries and file content are reconstructed from what remains on the drive or image.
-
4
Verification & Handover
Recovered files are verified for integrity before being returned on your destination media.
Important: What Not To Do
- Stop using the drive or device as soon as you notice the deletion.
- Do not save new files to the same drive, including recovery software installed after the fact.
- On an SSD, do not assume deleted files are recoverable — TRIM may have already cleared them.
- Do not run repeated scans or "repair" tools before the drive has been assessed.

Frequently Asked Questions
No. Recovery depends on the storage type and how much it has been used since deletion. Continued use reduces the chances of recovery, and on SSDs, TRIM can make recovery of deleted files impossible or severely limited.
On a hard drive, deleted data typically remains physically present until overwritten. On an SSD, TRIM can proactively clear the flash pages behind deleted files well before the drive is reused, which limits or prevents recovery in many cases.
Often, yes, provided the drive hasn't been heavily used since. Emptying the recycle bin removes the reference to the file, not necessarily the file data itself.
Stop using the affected drive or device right away, and avoid installing or running software on it. The best recovery chances come from acting before the drive is reused.
In many cases, yes, following the same principle — the sooner the device is stopped from further use, the better the chances.
