So something has changed with how the ROM is read/written. Perhaps it's a different baud rate that PC-3000 doesn't support, or they've changed the commands it's using to read/write the ROM
Also, 800041-000 board is not compatible with 4Tb Spyglass it only works for the 3Tb PebbleB drives. For the 4Tb Spyglass you must use SATA PCB 2060-800041-002 instead.
Amarbir, I purchase 4TB drives with SATA boards from eBay. The PCB model 2060-800022-000 REVP2 from the WD40NPZZ works with both the WD30NMZW and WD40NMZW. I just transfer the ROM chip. There is a lot going on under the hood with these SMR drives.Amarbir[CDR-Labs] wrote:Source of the post What Are The Other Issues You Guys Are Having In This Family Spyglass And Pebbleb , Any Suggestions From Were To Source 3TB And 4TB PCB Of SATA Interface Natively And Are You Able To Get Them In Ready State In Kernel Mode And Program ROM Or You Do a Swap By Desoldering And Soldering Method
Both chips I have seen, IS25WQ040 and Winbond 25Q40VWV1G, have pin1 marked on chip and the SATA boards have pin1 identifier on PCB. USB boards have omitted pin1 marker.Amarbir[CDR-Labs] wrote:Source of the post Another Great Thing Done By Brilliant Engineers In Western Digital PCB Design LAB is That They Have Omitted The Marker For Pin 1 .
