What i was saying was if you use some tool that can show the register status of the drive like MHDD, Victoria, etc or if you have any comercial firmware tool like PC-3000, MRT, HRT, etc and if you plug PCB only on ANY IBM BASED drive (arch M24, ARM based, etc) you should see this IF THE PCB IS STILL WORKING :
- Drive goes to BSY for a little while :

- Drive do report Drive Seek Complete and Readyness (Drive Ready) :

- From here you can issue the "universal" "Super ON" to gain access to NVRam for M24 arch drives or the Super On for ARM drives and then read RAM or read NVRam or whatever. This does work with PCB ONLY as explained !!!! Example on M24 arch :

As you can see i did dump NVRam with HRT and VSCs. If you don't have full HRT, HRT_DEMO + VSCs or any other firmware tool and you don't know how to dump NVRam or access RAM/ROM it doesn't matter, JUST USE MHDD, VICTORIA ETC AND MAKE SURE DRIVE GOES TO BSY AND THEN DRDY/DSC !!!!
On IBM/Hitachi/HGST (IBM NATIVE) drives with DAMAGED PCB on all cases that i did have so far there are NO ATA INTERFACE meaning normaly a fuse will blow or whatever and the PCB will NOT REPLY BY SATA/IDE meaning that with your firmware tool or MHDD, VICTORIA you will NOT SEE BSY and DRDY/DSC . You will only see exactly the same as if you were selecting a channel without drive ! There will be no register status as the PCB will be dead and it will be exactly like not plugging any drive at all. Depending on the system you might see all register status lit, error, abort, etc ..... i will display exactly as it would without any drive so no drdy and dsc.
