LaCie Recovery Lab Could Not Read the Platters: Evaluate an Extreme-Damage Second Opinion
A second specialist opinion is possible, but the odds are poor when an experienced recovery lab has already stopped after damaging two sets of donor heads. Treat the disk as a severe physical-media case. Do not power it on, attach another enclosure, try file-recovery software, or open it yourself.
In this LaCie 5TB recovery case on Reddit, PC Image in the UK had already attempted professional recovery. The owner reported that excessive media damage defeated two donor-head sets and asked whether an even more specialized lab could do anything meaningful. The original lab also explained in the discussion why it stopped rather than risk further head damage.
What Does the Failed Donor-Head Work Mean?
Donor heads are not a substitute for an undamaged recording surface. If the media repeatedly contaminates or damages replacement heads, another attempt may destroy additional equipment and damage still-readable areas. Seagate’s guidance on abnormal hard-drive sounds recognizes that some physical faults can damage the platters through continued operation.
This does not prove that every sector is gone, but it is much stronger evidence than a drive simply clicking or failing to mount. Ordinary imaging utilities cannot make the platters safe to read.
How to Evaluate a Second Opinion Without Another Blind Attempt
Ask the first lab for its written findings and any shareable diagnostic details: which head/surface areas were affected, whether any user-data sectors were successfully read, what failed during the second attempt, and whether the remaining media appeared stable enough to justify further work. Share that report with a specialist before shipping the drive or paying for more donor parts.
Decide Before Shipping
- Specialist offers a documented technical reason to try: Ask for the evaluation fee, failed-case charge, likely partial-recovery outcome, and an explicit stop condition.
- Another lab only proposes another head swap: That does not address the reported platter-damage mechanism.
- No lab can explain a different approach: Protect the drive from further operation and consider whether the value of the data justifies storing it for a possible future option.
There is no honest guarantee of recovery or a reliable success percentage from the information in the post. Recoverit, Disk Utility, and similar software cannot repair damaged platter surfaces or replace specialist cleanroom diagnostics.
