i think i need new pcb board for st3640323as Tried new sata-usb adapter, board started smoking & burned 2 of power tabs. Installed board from newer sgt 640 gb drive I had on hand with different firmware (orig SD13 vs new SD35)( before finding this forum, newbie on hd's ), received i/o error disconnected "immediately" and put board back on empty drive I took it from and that drive is ok. Drive has 550 gb data on it, was going to back it up to new 640 gb drive ( the one I took board from ) Hopefully, changing board will fix original drive. defective drive info... ST3640323AS P/N 9FZ134-300 FIRMWARE SD13 reverse side white tag info 1005125B5 D 7848PML PLS e-mail me at dhsvcs@aol.com |

Hi, "Just" changing the PCB will NOT work on this drive, trust me. No matter how close a match you get. The ROM on the board is unique to the drive. I tested this with two IDENTICAL known good drives from a RAID 0 configuration. Swapped the boards, no go. Until I moved then ROM's. Then they both worked again. Also, if you connect the PCB alone to test equipment (e.g. Salvation) the drive reports it's model number, f/w version and serial number. |
