LaCie Recovery Lab Could Not Read the Platters: Evaluate an Extreme-Damage Second Opinion
TL;DR:
While seeking a second data recovery opinion for a LaCie 5TB drive is possible after severe platter damage destroyed two sets of donor heads at the initial lab, success is highly unlikely and requires consulting a new specialist using the first lab's written diagnostics before attempting any further physical repairs.
● Request a detailed written report from the first lab, such as PC Image, specifying the affected surface areas, successfully read user-data sectors, and reasons for the donor head failures to evaluate options without another blind attempt.
● Do not power on the drive, attach another enclosure, or attempt repairs using software like Recoverit or Disk Utility, as Seagate's guidance confirms continued operation on physical faults can further damage platters and destroy still-readable areas.
● Only ship the drive to a second lab if they offer a documented technical approach addressing the specific platter-damage mechanism rather than proposing another head swap, while defining evaluation fees, failed-case charges, and an explicit stop condition.

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.
