Within MINUTES, I was at that magical F3 prompt in HyperTerminal, and within a few more minutes my drive was fully functional again! In my experience, using the direct USB-->TTY cable was a lot simpler than assembling a connector from a serial cable (USB-->Serial adapter for many people probably, as few computers these days have a serial port on the mobo). To any and all who come across this thread and this post, I would highly recommend the USB-->TTY cable. I purchased the jumper wires from the first post of this thread for $5, and the cable for $20. Yes, it's more money than the other solution, but I personally am willing to spend a few extra bucks if it means less headache and getting my drive back and working. I'd like to give my thanks to all the people who invested so much time and effort into this solution. I'm going to try to get the word out to everyone I know about the 7200.11 drives, hopefully I'll be able to prevent more people having to go through this whole ordeal. As an amusing fact, I live about 5 miles from Seagate's customer service facility in Scotts Valley, California, USA (listed as so on their support website). Getting this drive fixed means I don't have to go up there with eggs and TP... Hello everybody, I've just purchased the TTL-232R-3V3 Cable to fix the BSY problems that both of my seagate 1TB drives were having. I manage to get the F3 T> prompt in the hyperterminal. I am also able to key in the command /2 which changed the prompt to F3 2>. However, I am not able to enter command Z.Whenever i enter Z, I would encounter this error: LED:000000CE FAddr:00280569. Both of my drives exhibited the same problems. I have totally detached the PCB from the harddrive. Does anybody know what went wrong? Any help is greatly appreciated!
