Prepare SDXC (ExFat) for use with the iPod

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).

Rebuild MBR

Apply Action to Commit

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.

Delete All Partitions

Delete All Partitions

Unallocated Partition Table

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.

Create Partition

Aligned FAT32 Partition

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.

    Does anyone have suggestions on how to accomplish this with a Mac? I’ve got my iFlash installed, and I keep getting the error message due to my Sandisk 128 GB SDXC Card. I know it’s working because I get the restore message by replacing an old 2 Gig SD card. I bought my card through Best Buy so I could trust the card, but I can’t seem to find a good program to reformat and get the SD card ready for the iPod.

    hi, installed a solo with SanDisk 128GB Ultra SDXC on a 5th gen 30gb and everything went fine. all music loaded and played. accidentally let the battery die and now Ipod wont restore. Error 1429. What should i do?

    Hi Support and all,
    It’s my turn to ask for some advice. I have added an iFlash quad containing 4 x 512GB Integral micro SDXC cards to a 7th Generation iPod classic. The iPod formatted at 1.86TB, which sounds about right, and after restoring the iPod plus downloading whatever music I have on my laptop the iPod shows 150 GB used and 1762 GB free which at 1912 GB doesn’t quite agree with the formatted figure but it gets even worse than that because when the iPod is connected to iTunes it only registers 888.01 GB. I used the memory cards straight from the ‘box’ and only formatting the iPod when it was connected to the laptop and through ‘properties’ in Explorer so I wonder if going through the correct formatting, as suggested on this site, will sort it out. I have a 1.6 GB iPod that shows up correctly and was formatted in the way that I did this latest one so I can’t work out what has gone wrong with this one!! Has anyone any other suggestions please.

    Hi, I want to add a iflash adapter to my Ipod 5.5, I wonder if I can use 4/512gb card on it, I need to get ALAC and AIFF files so the number of songs will be less than 20,000, but I need more than 2TB on it…..

  5. Steve

    I got an Iflash solo to replace the 30GB hard disk on my 5th gen iPod.
    I purchased a 128GB SDXC card and to be honest i had no end of problems with slow transfer speed and the songs being corrupted after transfer. This was even after I followed the instructions above.
    I run Rockbox as the main OS and I read on a reddit post that when transferring the songs back onto the rebuilt Ipod do when the ipod is running the Apple OS. Not only did it the songs arrive uncorrupted but it increased my transfer speed from 5mb/s to 10mb/s.

    1. Support Post author

      @Steve – This is a known issue with the Rockbox ATA drivers, booting in to the Apple OS to do your transfers then booting back to Rockbox.

    After trying every possible solution to the 1439 restore error found on this thread, with my config – 4th gen 20 GB – MA079 – still no luck with either iFlash Solo or Quad using Kingston SDCS2/256GB 🙁 (not working even with an old 1 GB microSD card…)
    Communication with the adapter in the test menu:
    Any advice or should I give up?

    1. Support Post author

      @Karel – Your HDDspec screen has a lot of corruption on it – I would suspect you have a connection issue. Try another 4g Converter, if that does not resolve, then obtain a new HDD ribbon (these do fail and cause most of the 1439 errors on these older models).

    2. Neo Moucha

      @Support: I checked both cables with an ohm meter, no break in connection detected… I wonder – is this fit of the converter cable alright? There are 3 (x2=6) pins at one end without connection… ? At the other end, there is a plastic pin on the original connector, so this is the only possible position without removing of the plastic pin:

    3. Support Post author

      @ Karel – of course the installation is correct. The issue is you have a problem with one of the ribbons – corruption shown on the HDDspec occurs when there are problems in the data lines. You can try removing and re-inserting both ribbons and see if you can get a ‘clean’ HDDspec screen.

    Hi Lauren, apologies for the suspicions about fake cards but they are a real problem considering the amount of them for sale on eBay. I don’t know if this comment will be of any help but I have used a Samsung 1TB (useable 933 GB) ssd card in a iFlash adapter and that installed without issue and loaded up in one session. As you say the iFlash quad accepts 512 GB cards and I have a couple of 1.6 TB iPods that also restored and downloaded music from iTunes OK until I changed my PC for one with a ssd C drive and a 2 TB ‘data drive’ which, even with using an external drive for the iTunes library is still causing me recognition issues. I can’t see any replies to your query from ‘support’ so maybe it could be a board issue!

    1. Lauren Glenn

      I’m using a Sandisk card, so it very well could be something in the board. But at least Support has said, “we haven’t ‘officially’ tested 1TB cards.” That makes sense to me. Sandisk did come out first, so the fact maybe it doesn’t work could make sense. But if they get one and then it works after a new board revision…. then I’ll buy a new one. It’s only $40, so it’s not the end of the world to get another 2TB. Until then, I’ll just keep it in my Android tablet.

    2. Lauren Glenn

      Honestly, I don’t see Samsung selling a 1TB micro SD card anywhere on the internet, so I’m wondering where you got this card. The only other company I saw someone sell that made one was Lexar.

  8. Cem Kaygi (Jim)

    I have a 30 Gig, 5G Classic Ipod. I installed the Solo card with a 256 Gig sd card. After installing the RockBox which is a very satisfactory setup, I can only transfer one file, (album) at atime. The Ipod locs up and I have to reset the Ipod, pressing Menu and Select while still connected to the computer via USB. Then I can transfer another file and do the same thing again. Where did I mess up?

  9. Peter

    – Replying to Lauren Glenn’s problem can I ask where you got your 1TB memory card from as unless the card is from a reputable seller and manufacturer then the card may, almost certainly will be a fake. I have a collection of cards that came on packaging that was indistinguishable from the genuine article but when checked on ‘h2testw’ (on high GB cards the test may not get all the way through but will be enough to check if the card is genuine) software you soon see if the card is real or has been electronically altered to show the advertised GB amount. If your’re lucky you might get a 16 or 32 GB card yet when you format the card a 512 GB will often show up as 480 – 490 GB. This is also a sign of a fake because a genuine 1 TB card would give around 930ish GB so a 512 GB card would be half that at 465 – 470 GB. Groupon has a 1 TB card for sale for £13.00 so I though I’ll give it a try because I can always get a refund if it’s fake so I purchased 2 and both were 32 GB cards electronically manipulated. I eventually managed to get both refunded but had to send the cards back and they tried to get away with just refunding for 1 but I’ve fought enough battles on eBay to obtain refunds for fake cards and never lost yet. I complained to Groupon suggesting that they stop selling the fakes and pointed out how ridiculous it was sending back fake cards to a seller who will only sell them on and dupe some other poor buyer and I suspect ther rely on the fact that many wouldn’t be bothered to try and get a refund for ‘only’ £13.00 pus P & P. If you do have a genuine card then I would do all the methods of reformatting and checking the card that are suggested via sites mentioned on Google and if there is still an issue then get in touch with the card manufacturer as the card could be faulty. It can be a fiddly process but worth it.

    1. Lauren Glenn

      I see the problem… you think I don’t know anything about micro SD cards and would think I could buy a 1TB for $25.

      No, the card is real. I’ve been using it in my Surface Pro 6 without incident. What you’re talking about is having a lower capacity card that’s faked to look larger. This one works just fine on a PC without data loss. This card when plugged into the board causes the total storage of the whole board to report incorrectly as if it can’t handle a 1TB card.

      This card was bought on Amazon. And yes, I’ve cleared the partition table with DISKPART…. loaded in the iPod Classic and then it won’t see the storage once the card is put in. However, if I format as NTFS on a PC, it all works just fine. Even after loading hundreds of GB on it.

    2. Lauren Glenn

      Storage on the card is reported as 953GB

      Total size reports as 999,873,519 kB = 1,023,870,483,456 bytes

  10. Lauren Glenn

    Has anyone tried a 1TB micro SD card in an iFlash Quad? I put one in mine and I don’t know what the issue is but the drive would always report as 200GB regardless of the other cards on the board. I cleaned all the partitions with DISKPART and put them back in the iPod…. it still kept saying 200GB even if the total was < 2TB. After putting back in my 4x 512GB cards, it went back to normal.

    I noticed 1TB isn't on the compatibility list here, so I wonder if this is something that was fixed in a later revision or what. Windows 10 supposedly allows for 16TB on MBR with 4k sectors (which the iPod uses)…. but I couldn't even get the card to work yet.

    1. Lauren Glenn

      And before I get any more “are you sure you didn’t buy a $10 card thinking you got 1TB because you’re a woman?”, has anyone actually tried this that wasn’t using Rockbox? The only person I saw try to format a 4TB raid 0 wasn’t using the iPod to read it. The card formats fine in Windows but when I format on the iPod, the total space is not reported correctly. In the “1TB for $10 example”, you’d see it had a total space of 1TB but you’d only be able to write a small amount before full.

      That’s not what’s happening here. It looks like the board cannot see more than 200GB if you use a card over 512GB. And for me, I have NO problem buying a new iFlash quad if a new revision fixes this. If one doesn’t fix it, then my other solution is to use this card in something else and then just buy a second iPod.

    2. Lauren Glenn

      Thanks @Support. I look forward to seeing what the result of the tests are. But like the 512GB card rollout, I wouldn’t expect it to come until the card drops in price to $99 or something.

      But if you need someone to test a card…. 😉

    Hi, thank you for the guide. After much trial and error I recently got my ipod to sync correctly to an SDXC 128gb. However once I started the ipod and selected a song, the ipod hung for ages and then crashed. Now the drive is corrupted, does anybody know anything to try here or is it likely something to do with the card? I figure if it was a sync error the the sync would have failed.
    Thank you

    My iPod Classic 6th gen keeps getting corrupted when trying to import my library onto it. Loading a few songs works but trying to load a lot of songs causes it to become unreadable and requiring a new restore, thereby erasing all my music. I’m using a Samsung Evo 128GB micro SD card I got on eBay. Any ideas why this may be happening?

    1. Stephen Islip

      My experience was9 out of 10 sd cards bought from eBay we’re corrupt. If you ask for a refund they give you a refund without asking for it back . Because so many mugs do no find they are corrupt until the return period is over. A photographer advised me buy integral cards from Amazon where you can read customer reviews. I did that and got an excellent 512 go card

    2. Jason

      Thanks for the information. Unfortunately I bought this card a year ago and it’s not even showing up in my purchase history so a refund is a forgone conclusion. I always buy from American sellers and the thing came in Samsung packaging and it looks like a Samsung card but I wouldn’t doubt it’s a fake after hearing what I’ve heard about eBay cards.

    3. Support Post author

      @Jason – We always suggest running something like H2Testw on newly purchased SD cards, first it gives the card a good workout, but more importantly to confirm what you have is can store the actual stated capacity. We follow this advice regardless of where a card is bought.

      Fake cards sold on Amazon/Ebay/Etc are factory reject small capacity SD/SDHC cards normally 8GB,16GB,32GB cards which have been reprogrammed to appear as larger capacity cards, hence once you write beyond the original capacity you get corruption as the data is being written over areas already written to.
