Hi, I turned on my PS3 for the first time in ages a couple of weeks ago and it made all sorts of dead HDD noises. I bought a replacement drive on eBay (all working perfectly), swapped it over, turned on the PS3 and got the prompt to insert the update media. Downloaded the firmware from the Sony site, stuck in on a USB stick, tried that, and got the "No applicable update data was found" error. The USB stick is FAT32 formatted. The folder structure is correct (/PS3/UPDATE/PS3UPDAT.PUP). I've also downloaded the update file a few times, just in case of corruption (identical each time). I've found all sorts of (probably wrong) advice on YouTube - must be a USB2 not USB3 stick (I've tried 3, and an old USB HDD), pull the controller USB out as it's checking for firmware (really?!), rename the update file to something else (nope!) - I cannot get the PS3 to recognise that the firmware is inserted. No joy. The only thing I can think of is that I'm creating the USB stick on a Mac, as that's all I've got available. But that shouldn't make a difference, the file system is correct, I've even made sure there are none of the usual OSX hidden files on it or extended file attributes etc.... Any ideas before I bin it? Thanks!
