Start with these three steps
Stop unnecessary activity
Avoid installing recovery software, macOS or updates on the affected storage. If the iMac freezes repeatedly or the SSD disappears, stop testing it.
Identify the configuration
Provide the iMac model and any storage-upgrade history. Note whether the missing files were internal, on an external SSD or on a former Fusion Drive.
Check independent copies
Use a different device to inspect cloud originals, exports and backups. Record what is missing rather than performing another full scan just to compare results.
iMac SSDs do not all have the same recovery path
Apple’s 2020 27-inch iMac and M1 24-inch iMac specifications list SSD storage, while older iMac specifications include several storage choices. A previous owner may also have changed an older computer’s drive. Include this history when requesting an assessment.
Do not order an adapter solely from the word SSD. Ask whether the exact storage can be accessed separately or needs the complete original system. Keep any removed modules, boards and repair notes together until that question has been answered.

Readable flash is not automatically readable files
Apple explains that internal storage on Apple silicon and T2 Macs uses hardware-based encryption even when FileVault was not enabled by the user. The recovery implications therefore extend beyond knowing a login password or removing a storage component.
Preserve the original electronics. Ask what parts must remain functional to produce decrypted files and what a proposed board replacement would do to that route. A promise to read chips alone is not evidence that usable data can be reconstructed.

Separate inaccessible storage from deleted content
A controller or electrical fault that prevents access is different from a healthy SSD on which files were deleted. Data Recovery Lab NZ describes SSD recovery as dependent on the controller, flash and related metadata. There is no universal repair that applies to every iMac SSD.
TRIM and the SSD’s internal cleanup can make deleted blocks unavailable without an obvious new file taking their place. Avoid treating an SSD like a magnetic disk where an undelete scan is assumed to find everything. Stopping use preserves options but cannot reverse work the controller has already completed.
Ask for model-specific evidence
The external provider Data Recovery Lab NZ publishes SATA and NVMe SSD services. Confirm support for the exact iMac and storage arrangement rather than extrapolating from a generic SSD listing. Describe whether the drive is absent, intermittently visible or readable with missing files.
Agree on priority folders and the return format. If you need a Photos library or a video project, ask whether dependencies and structure can be checked as well as individual files. Keep the source until you have opened the delivered results on separate storage.
A realistic view of recovery
- Completed secure erasure, lost encryption material and severely damaged flash can prevent recovery.
- An SSD that stays silent or appears briefly is not necessarily stable enough for repeated scanning.
Your questions, answered
Can every iMac SSD be removed and read in another computer?
Does TRIM make every deleted file instantly unrecoverable?
Can chip-off recovery bypass Apple encryption?
