Welcome to Cardiff Data Recovery, Wales’s most trusted name in data recovery. If your Razer laptop is showing a whirring sound from its 2.5″ Seagate hard drive but is no longer being detected, it likely indicates a mechanical failure involving the read/write heads.
With over 25 years of specialised experience, our engineers are experts in handling delicate drive failures and have successfully recovered data from countless Seagate 2.5″ laptop drives with similar issues.
⚠️ Understanding the Issue – Whirring Sound with No Detection
When a Seagate hard disk is spinning (motor functional) but not recognised by the BIOS or system, the problem is usually with the internal mechanics, including:
- Damaged or misaligned read/write heads
- Firmware stuck in a busy state
- Servo data or head preamp failure
- Minor platter damage from a head crash
This issue cannot be resolved with software recovery tools and requires physical intervention.
🛠️ Step-by-Step: How We Recover Data from Seagate Drives with Head Failure
Step 1: Secure Drive Intake & Initial Diagnostics
- The drive is carefully labelled, serialised, and electronically write-blocked.
- We assess basic electrical functions and determine that the spindle motor is working but no data is being read.
Step 2: Evaluation
- The drive is disassembled.
- Read/write heads are microscopically inspected for damage or misalignment.
Step 3: Donor Part Matching & Head Assembly Replacement
- A matching Seagate donor drive is selected based on:
- Model number
- P/N and firmware revision
- Head map compatibility
- The damaged head assembly is carefully removed and replaced with a functional one.
Step 4: Firmware & ROM Integrity Check
- We verify the firmware modules and loader status, especially in Seagate drives known for “BSY” (busy) firmware lockups.
- In some cases, firmware repair or ROM transplant is required to allow access to the drive surface.
Step 5: Controlled Imaging Process
- A sector-by-sector image is created using hardware tools capable of handling unstable Seagate heads.
- Bad sectors are bypassed using adaptive head mapping and soft ECC error handling.
Step 6: File System Recovery
- Once imaging is complete, we mount the image and begin rebuilding the file system (typically NTFS or exFAT for Razer laptops).
- Data is recovered in original folder structure, including filenames, timestamps, and metadata.
Step 7: Data Delivery & Verification
- All recovered files are verified for integrity.
- Data is returned on a secure external medium or according to client preference.
