Hello, i'm newbie (sorry) I receive my usb to ttl adapter I plug, with various HDD and all is ok Now I want to backup my original firmware before try to play with it. I attemp with sediv (free version) but when i want to read I have the message 'only full version' If I have understand, the firmware is composed by 3 part: 1 in rom, and 2 in hdd track (no direct access track "-41"). when i attemp to do lot of command , I have : "INVALID Cert Disk Code - ROM resident revision required APN140" if i understand, i need to put an cert in rom (or on track ?) before send order to read firmware ? thanks for your help ps: Test Disk information Barracuda 7200.ES GALAXY3D firm :3.APPZ serial: 9QG84TZN on boot disk say me : Reset 4096k x 32 DRAM GALAXY - 1_Disk S-6D 02-02-07_11:01 on ^L : 2>GALAXY3D - 3_Disk 3.APPZ 12-03-07_17:44 APN,GX_3D_6H_S,14 Built for GALAXY3D,PITKIN,Redback,TI1843 PreAmp,Agere7539 PreAmp,McKinleyDT,3Disk,220 Servos,7200RPM,8Pole,133MHz,RwFeat=0002,VBAR |

this hdd work fine i don't think there is a damaged cert track but it's possible it was an IBM remanufactured seagate. For the paid version software, I read that lot of soft allow to read the firmware but we need to pay to write it, correct ? stcom is ok, but my version is not translated , (i use screeshot to know witch button to press). I think all my hdd is older than F3 arch. In my mind,i want to bkp all firm that I found and upload to this site, but if my bkp is corrupt, how can I detect it since I can't write it back to hdd ? |
