Hi, I bought a new 80 gb hard drive for my iPod 5.5 recently, after connecting to iTunes I got error -1416. I have tried different computers ( Mac Mini 2010 / iMac 2010 / iMac 2014 / Acer Win10 ) with the same result, I cannot restore/format the drive without getting POSIX...-devicebusy error. I have tried all solutions (as suggested above) with no luck, only Terminal $sudo diskutil zeroDisk /dev/myiPod worked, but still cannot restore it! I can boot into diagnostic mode, HD-SMART test displays regular new-and-working hard drive info, so I'm thinking about replacing the flex, connector cable and battery (it charges only to 10%) to see if one of these three or maybe all are making the difference.
this might be able to help you If you enter the wrong passcode six times in a row on your iphone, ipad , or ipod touch you’ll be locked out and you’ll see this message: iPhone is disabled iPad is disabled iPod touch is disabled Recovery method is the sure fire , quickest way to get back access to your ipad, but if you don’t have a back up file of your ipad then you will be going back to factory reset mode with recovery mode i found this inforamtion online ..it might help ..

Seconded... Though I'm afraid that the answer will be that you have to buy a parts calculator. I contacted TI about this some time ago (specifically looking to buy replacement keys), and they said all that they could do for me was to send the calculator in and that they would send me back a refurbished one. As I recall, the cost of this was at least half of retail ($75 sticks out in my mind).
The Mac Mini Mid 2011 supports up to 8GB DDR3-1333 MHz of RAM officially. However, one can install 16GB DDR3-1333 MHz of RAM or DDR3-1600 MHz RAM in both amounts. The SODIMM Modules fit but simply down-clock. I have 16GB DDR3-1600 in my 2.3GHz Mid 2011 Mac Mini and it runs perfectly and passes all of the standard Apple ASD testing. If you are installing 16GB modules make sure to do memory testing because there is a higher defect rate in 8GB chips when compared to their 2GB and 4GB cousins.
I also have a mid 2009 Macbook. I'm looking to buy the optical bay HDD enclosure too. However the item that Mayer links to does not say anything about fitting the Mid 2009 macbook. It specifies that it's compatible with the late 2008 (Aluminum) Macbook, and the later unibody models. Nothing about the mid 2009 non-unibody models. So, as Steven Quan says, should I buy the Unibody-style optical bay hdd enclosure?
The dev switch is accessable without opening the device. It is on the right hand side of the device behind the SIM slot cover. Edit: You can see it right below the SIM slot on the Step 14 teardown picture.
