Trex> sa default
Trex> i4,1,1

(This loads default SA location pointers.)

Step 3: Locate Module 02 (Translator)

Trex> dir list

→ Look for 02 in the list. If it’s missing or shows BAD CRC, you proceed.

Step 4: Force Module 02 Regeneration

Trex> module 02 gen
Trex> module 02 save
Trex> translator rebuild

Step 5: Regenerate P-List from Defects

Trex> plist show
Trex> plist rebuild
Trex> psa save

Step 6: Final Initialization

Trex> reset
Trex> init

→ Success output: Model: WDC WD10EZEX-00WN4A0 Firmware: 01.01A01 Capacity: 1,000,204,886,016 LBA Status: DRD,DSC

Fix #2: Clicking Heads (Slow or Fast)

Symptom: Drive clicks 10-20 times then spins down. Cause: Dead head (physical), damaged servo tracks, or corrupted SA module on a specific head. Trex 2 Fix (Head Masking):

  1. Enter level=wd then info. Note the number of heads (e.g., Hd=4).
  2. Type head test to identify failing head (it will error out on Head 2 or 3).
  3. Type head map to view current mapping.
  4. To disable Head 2: head mask 0,1,3 (removes head 2 from the map).
  5. Type translator reg (rebuild translator without the dead head).
  6. Warning: This is a DANGEROUS fix—you lose all data on that head’s surface. But for "pro repair" to recover remaining data, it is valid.
