Thank you, I thought I needed to format my 256gb mSATA card after the iPod fully drained but when I removed it and installed in the iPod that has the 480gb card it worked. So this means that the last mSATA to ZIF adapter that I got of Alibaba failed beause I get the iPod sad face when I use it.
Also I had to fully charge the slims battery of the 480gb iPod after I did thee card swap, looks like it was completely dead and the iPod couldn't boot of it. (This is the first time this happpen to me)
I will order that adapter, I may end up using for my Thinkpad X60 after I upgrade the capless iPod to 1TB. I saw the prices going down for those cards.
Because I am testing a lot of iPod batteries recently, I started keeping an old iPod V5.0 with an 8g CF card in a Tarkan free as a means to charge batteries. Everyday I charge batteries with this iPod, just in case I run into issues with complete battery discharge (which has happened very regularly since I started running stress testing on the 480g and the TeraPods). If not for this "battery charging ipod" I would not be able to run the tests I've conducted in the last two weeks.
Remove the adapter from the computer only after shutdown. If you remove while the power is on, the chip will lock and cannot be restored in iTunes.
I am really surprised the slim battery works. I think my next build will be a U2 Thin TeraPod - just because I can.
