UNBRICKED two harddiscs! 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.

@Maxtorman: Hello. First I want to say, that its really nice that someone says the truth cause many people worry about theire data. I trusted seagate that they tested the firmware upgrade and tried the bricking update. I had two ST2500320AS and the upgrade just updated both HDs at once, leading to a killed main HD and a killed backup HD. :( Now some people had successfully downgraded their drive that has SD15 to SD1A and then downgraded back to AD14. But this only works on 1 of 4 drives. One report was that it worked on a drive with a serial number starting with 9QM but didnt worked on a drive with a serial number starting with 5QM. Now my drives have 9QM and I think about to try a downgrad with one drive. Can you say something to that? How risky is it? Another alternative is to buy a new drive and swap the PCB. Third alternative is to hope seagate brings a un-bricking firmware update this days. Fourth alternative would be sending the drive in but I think this woul cost a week more and I need the data. Do you have any information about why the downgrade to AD14 works for some or not? Or can you maybe get some information about it? Best regards Robert
