I cannot access to the hard details with my PC too and it donot detect in my laptop bios but I think its motor work and I hear its voice good. because I saved my Maxtor hard drive (STM3500320AS) that donot detected in my pc before with this topic ways,I think maybe I could solve this hard problem too with this way. My laptop hard information: Model : WD3200BEVT S/N : WD - WXE508FH4819 Anybody had this problem before? Can you guide me? Best Regards, SHP Anybody donot know the answer? I think you have BSY problem. STM3500320AS of maxtor works as ST3500320AS of Seagate. You need "RS232 to TTL adapter" or "USB to TTL adapter" to repair it. To unmount the PCB you need torx 6 screwdriver.
