UNBRICKED my two harddiscs! All data is completely fine. I had two working ST3500320AS that got bricked by the SD1A update. I was able to "unbrick" these two drives by downgrading to the public aviable AD14 update. This downgrade doesnt work for all ST3500320AS but for some. If youre drive is similar to this data, you could try the downgrad if you need your data fast. If you have time, I suggest to wait / request the correct/perfect firmware from the seagate support. Here are the data fomr the drives: Purchase firmware: SD15 Pre-flash firmware: SD15 Serial: 9QM09XXX Date: (only got date code) 08235 Produced in: Thailand Site code: KRATSG P/N: 9BX154-303 Purchase firmware: SD15 Pre-flash firmware: SD15 Serial: 9QM0BXXX Date: (only got date code) 08235 Produced in: Thailand Site code: KRATSG P/N: 9BX154-303 The AD14 update is according the readme only for ST3500320AS's -301 and -302 but i risked it and it worked.
