Well you screenshots shows very clear whats wrong " USAG no copies read" List of modules can´t be read from SA, you need to fix that. |

Thanks Spildit but the resource store is not the same loader due to I tested that before ( 3. using from resource store from donor after that Hdd detect and access to sa but can't read any sector from sa or lba ) and if is that something else how I can create that because pc3000-udma did n't have option for create that and in folder utility start resource

In my working Hdd (donor hdd ) 1. I wrote 00 to USAG modules (copy 0,1) 2. after re power hard drive did't detect 3. I used from using restore resource then I can access to SA even data surface (I have had backup from modules) result in pc3000 don't need to create loader it can be used from modules automate

If i understand you correct, you got access to patient SA. Save patient A modules to your startup folder and use them instead. |

it seems something go wrong  I tested with other family of working Arm Hitachi drive , 1. I wrote 00 to the first of USAG modules (copy 0,1) 2. after re power hard drive did't detect 3. I used from using restore resource with same firmware (from other hdd with the sames model and the same fw) vow hdd detected and I accessed to sa ( read and wrote ) but i dint have surface ( duo to A modules in loader ) I find that my problem is in other place , maybe head or nv-ram,... |

Hi, Does anyone have a solution for this issue. There is no access to SA at all. We have tried head change and and also edit NVRAM no success. We have also same F/W drive and used loader. Ace have looked at it remotely and said that there is no solution. |
