Seagate Drive : ST3500620AS , Firmware : HP24 Location : Belgium Problem : BSY Original machine : HP Succesfull recovery I used the solution described by AlexLillic on page 35 : With a few small differences (only hardware) : all from RS website(international) USB TTL cable & Torx screw drivers ordered from RS components (delivery in 2 days) USB TTL Cable : 429-307 Torx T6 : 243-456 IC Socket : 813-115 Connector for connecting TTL cable (male) : 334-561 For the cable connection onto the Seagate drive I used the pins from an empty IC socket ,and soldered it onto a cable. Also used heatshrink tubing (just get a few sizes from your local electronics store to get the good size,else you need to order a whole box) as an isolator around the end of the IC foots,so they won't touch one another. Thanks AlexLillic,Gradius and others ... I'm looking forward to more goodies ,and you made me get the taste for datarecovery. I still wonder where you got the actual list of commands for the controller board ? Anyone knows were to get those (for seagate and other boards too)? This might enable us to do this same stuff for other brands and models too. Kind regards, K.
