Prepare SDXC (ExFat) for use with the iPod

*** IMPORTANT – This article is up as an reference, first install and restore the iPod, if you have problems then attempt these instructions ***


Some of the factory fresh ExFAT formatted SDXC cards cause problems in the iPod, I have not been able to determine the exact cause but I suspect the iTunes restore process does not write a fresh MBR (Master Boot Record) nor does it create a new partition table – just modifies the existing table.

This only applies to SDXC cards 64Gb and above in capacity, as these are the cards which are ExFAT formatted by default.

The symptoms tend to be slow music transfer, odd syncing errors, song skipping and iPod freezing up.

I have created a walk through on how to get the SDXC card in to a known good state before installing and restoring the iPod.


First you need to get a partition manager software, I use the free AOMEI Partition Assistant, download here!! but only for Windows PC’s, for MAC users any of the popular partition software on MacOS will work. The steps will be slightly different, but the process and concepts should be similar.

You will need a CF card reader, you can also use a SDXC card reader. If you are going to use a SD card reader make sure it is SDXC compatible as you can damage the SDXC card – normal SD or SDHC card readers will not work with SDXC cards.


IMPORTANT: Make sure that the drive you are modifying is the SDXC card and not another Hard Drive installed in your Computer, you have been warned. So before starting double check that you are working on the SDXC card – better safe than sorry!!

Install SDXC card in to SD-CF Adapter, and place it in the CF card reader. In the example below I am using a 256Gb SDXC – It is shown as removeable in the drive list.

Start AOMEI.

In the main window, right click on the SDXC drive and select REBUILD MBR and confirm, leaving the default Windows 7/8. To commit the action you need to APPLY (Top Left Icon).

Once that has finished, again right click on the SDXC card and select DELETE ALL PARTITIONS, and Apply to Commit – once that is finished the drive should be totally unallocated.

Now we can write a fresh FAT32 Partition. Once again right click on the SDXC card, select Create Partition. On the dialog window, click on Advanced and select SSD Parition Alignment – leave the default setting of Optimised. Apply to Commit.

Once all the steps have been completed, your partition table should look like this :-

Now you can safely eject / remove the SD-CF Adapter from the CF card reader and install in your iPod, ready for the iTunes restore process.

    @JUN – As mentioned in the article – the best thing would be just to install everything and restore using iTunes, it is generally not necessary to format the cards beforehand.

    @Lucie – Yes you probably have to, there must be a previous format on the mSata drive that the restore process could not clear.

    Hi– I just upgraded my iPod classic (160GB, thin) using your iFlash SATA adapter and 1 TB Samsung SSD 850 EVO mSATA. Everything seems to be working fine–it turns on and restores with no problem–except that it thinks it only has 22 GB capacity. Do you think I need to format the drive using the process above? Appreciate any help!

    @John – Rockbox USB drivers has issues with solid state drives, the fastest writes speeds will be achieved booting back in to the Apple OS (Diskmode tends to be slow, normal mode is best) to do the drag & dropping.

    Ultimately write speeds on MicroSD tend to be much slower then fullsize SD cards. Also there is a lot of variation when I tested the Samsung 128Gb EVO on a 7g I barely managed 14-15MB/s, where as the slower spec’d Sandisk Ultra 200Gb achieved nearer 19MB/s.

    Figures are for the 7g, the 5g/5.5g transfers tend be slower than that.

    So got my ipod video working with the quad micro sdxc adapter and I’m using a 128 and two 64’s. Everything works as it should but the transfer speeds are a let down, I’m getting are 3 to 6 mbps when booted on rockbox and 3 mbps max when in disk mode. Are these speeds normal and is there anything I can do to increase transfer speeds?

    @Jake – If the music players used a standard FAT32 partition table then you should be ok to just install and use iTunes to restore. If you are going to format then format to FAT32, you can then choose Mac format during the iTunes restore process.

    I recently bought a quad for my 7G classic, and if I plan on using a
    200gb microsd, new
    200gb micro sd previously used in a music player
    and 128gb micro sd previously used in a camera
    should I reformat the ones previously used, before putting them in? Should I reformat all of them for uniformity? Or would it be enough to erase all of the current files on them.

    If I should re format (I’m on a mac)–should I choose FAT32, Mac OS extended, or ExFAT?

    all of the memory cards are sandisk ultras, by the way
