I have an oem Tosheba 30gb hd removed from my Z1 unit. I replaced it with a 40gb unit.

 

I installed the Z2 update on the 30gb oem hd. I have it for sale on ebay if anyone is interested. (cheap)

 

I guarantee it to work perfectly. It has brand new partitions and OEM files

used in Z2 upgrade.

 

thanks
