Can I upgrade my gen 5.5 30gb HDD with gen7 160gb HDD?
@jeth it is not the size of the case! That could be resolved by using a backplate from an iPod 5th gen thick, the issue here is that your 5th gen Video does not read the 7th gen Hard Drive at all. They are not interchangeable which has nothing to do with it’s thickness.
Don’t understand most of the posted answers as the OP asked if a gen 7 (thin) hdd can be used in a gen 5.5 (thick) Ipod. I have successfully done exactly that. I do recall that the gen 5.5 may not have initially recognized the full gen 7 160gb hdd size - 128 if I recall correctly. Cheers!
Sadly the case depth is too shallow. How about making the big jump into a SSD drive config. Here’s one offering: iFlash iPod Adapters
