If you receive the following error message: “iPod is Mac formatted (HFS+). Switching to “Read Only” mode” after connecting your iPod to CopyTrans Manager and all the listed music tracks are greyed out, read the information below to troubleshoot.
All iPod models except iPhone, iPod Touch and iPad can use two different file systems to store their files: FAT32 and HFS+.
iPods first synchronized on a Mac are in HFS+ format while iPods first synchronized on a PC are in FAT32 format. Mac computers can read and write to both HFS+ and FAT32 iPods; however, Windows PCs can only use FAT32 iPods.
CopyTrans Manager can read and write iPods in FAT32 format but it can only read iPods in HFS+ format. We therefore recommend you to switch to FAT32 format.
How to switch from HFS+ to FAT32
First thing is to backup the whole contents of your iPod to iTunes. You can easily do that with CopyTrans:
Once the backup is complete and you are 100% sure to have all the data stored in a safe place, you can connect the iPod to iTunes and authorize iTunes to restore the iPod. iTunes will automatically restore it in FAT32 format. Think twice before you restore the iPod as it cannot be undone.
