iPOD and SDHC – SDXC cards

iPOD and SDHC – SDXC cards

Introduction

For some time many people have wanted to use my iFlash iPod CF adapter with the new generation of large format SD memory cards. SDHC and SDXC are the new generation of SD cards which are cheaper and have capacities of upto 256Gb and growing.

Installation is simple, the iFlash is first installed – then install the SD card in to your SD-CF Adapter – finally insert the whole thing in to the iFlash, ready to restore the iPod.

SDHC and SDXC which cards to get

So far all the SDHC and SDXC cards I tested worked ok, so it is looking likely that majority of the SD cards out there will work ok.

In terms of card speed, one user has reported issues playing FLACS with a Class 4 card. I would suggest you want a minimum of a Class 6 card with Class 10 the prefered option.

So far… working and tested in 5g / 6g / 7g iPods

The current compatibility list has been moved to the iFlash-Solo product page.

    OK, did the secure delete of the first (24mb +120gb) partitions, and STILL it comes out at 459gb!!
    The ipod says it has 977gb, which looks impressive, but as the PC can’t see half of it, I can’t use it.

    Starting to think something is wrong with the new PNY card – though quite exasperatingly I have lost track of which one was the new one.

    @Peter – I don’t think the issues are with the SD cards or the iFlash-Dual.

    Has iTunes updated for it to be that?

    What happens if you install the 256Gb in to slot SD1 and 512Gb in to SD2, does this still restore to 459Gb?

    I think you should try the secure wipe on AOMEI at least for the first 64Gb maybe to 128Gb – you want to remove data from the start of each of the 3 partitions that the iPod/iTunes creates on the storage device.

    After wiping everything maybe try restoring another computer – it might be possible there is corruption in the registry or iTunes connected to the device id (GUID) of your iPod.

    This is a very frustrating mystery. There has to be a way round it, given I’ve mixed various capacity cards in the dual adaptor in the past, including 512+256 (which now won’t work). I just can’t work out what has changed.

    Could iTunes behaviour when restoring have changed due to an update? A driver issue?

    AOMEII sees it as a single partition with the full ~1Tb disk capacity but iTunes only sees 459gb. The full capcity is noted in device manager, but once restored by iTunes windows explorer can only see 459Gb. The iPod itself reports the correct capacity, both in OF and Rockbox.

    What do these differences mean? Seems as if its iTunes behaviour that is the problem.

    Nothing seems to resolve this.

    If I put it into DFU mode, iTunes prepares it for recovery, then it just comes back as it was, with just the first card formatted.

    If I install rockbox on it using the new bootloader it works, but both rockbox and OF can see the full capacity but, again, the PC can’t (though AOMEII still can).

    Deleting the first, 24mb partition ‘securely’ in AOMEII hasn’t helped either, and deleting the second, larger, one that way takes 5 hours so I haven’t attempted it.

    I suppose I could try the ‘secure delete’ – I think by default AOMEII just does a ‘quick’ format, right?

    Thanks for suggestions.

    I actually started loading up in 5.5 gen (which appeared to be working) before deciding syncing that pod is far too slow, and went back to trying 7 gen again.
    Did the MBR thing on both cards.
    Whatever I do I get the same outcome – explorer/iTunes only sees 469gb, even though the ipod itself reports the full amount in OF or Rockbox, and AOMEII sees the full amount as well.

    @Peter – Very unlikely it is to do with the card, as you had one of the cards working in a 768Gb combination – Only the card in slot SD1 has the MBR & Partition data written to it, SD2 card will not have any info related to formatting or partitioning, in fact when you first restore the iPod the second card (SD2) will not have anything changed on it at all as nothing is written to it.

    Have you tried the MBR re-writing?

    Couple more things you can try – using AOMEI do a secure delete of the cards for at least the first 64Gb in case there is some sort of partition table which is causing confusion during the restore process. Lastly maybe switch to Rockbox and partition & format as done in my rockbox new bootloader article, then go back to iTunes via the DFU recovery – in case your external card reader is causing an issue with the card as this method will allow you to partition/MBR/format while the cards are installed in the iPod.

    The fact that you cannot even get your 768Gb combination working again points to some stray data residing on the SD cards which is causing confusion for the restore process.

    @Support, oh, only just saw your last suggestion. But I did try DFU mode a couple of times, and got same result.
    New card was from Amazon like the first, so doubt it could be fake.

  8. Peter

    @Support

    Even tried it in a different 7th gen, same result. Baffled. Have to settle for using a 5.5gen, where at least iTunes, and rockbox, seem to install correctly and it reports the correct size. Have to hope nothing goes wrong when doing a full sync (perhaps it will still fail when exceeding 459gb?).

  9. Peter

    @Support
    To be clearer – windows _explorer_ shows 459Gb, but windows control panel device manager shows the full size. And windows disk manager shows both – 972gb in the diagram, 459gb in the text list.
    Also I’ve now given up and put it into a 5.5 gen instead – which appears to work (though I’d rather be using the 7th gen).
    Also tried a different dual adapter, with same result. Its as if something has gone weird with the ipod and its become fixated with the figure of 459gb…or there’s something different about the supposedly identical newer PNY card and it isn’t being seen correctly. Its frustrating.

    @Peter – That all is very strange, so to confirm the windows explorer icon with the iPod shows the correct capacity? but iTunes when restored only shows 459Gb? What does the partition table look like in AOMEI and also in windows disk management console?

    Can you tell me what the LBA size is in the iPod diagnostics? also when you formatted the SD cards in the external card reader did you also rewrite the MBR as well as delete all partition data before creating a new FAT32 Partition, it is possible the MBR has the disk geometry as 512Gb still.

    Finally it may be worth going to the SDIO website and get their SD formatter and taking both cards back to factory ExFat format, and re-install without doing any formatting.

  11. Peter

    Weirder still – putting back the 512gb + 256gb combo that previously worked perfectly well, now only reports 459Gb capacity.

  12. Peter

    This is really weird. Viewed in windows disk manager the pictogram clearly states its a healthy FAT32 partition of 972.06Gb. But the text list says the capacity is 459.11Gb. What does it mean if these two figures contradict each other?

  13. Peter

    Turns out either card will work on its own, but the two together always come out as _less_ capacity than one on its own! Yet the ipod itself and AOMEII can see the full capacity, but explorer and iTunes can’t.

  14. Peter

    @rubeN

    Yeah, reformatted both cards with card-reader and AOMEII.
    The newer card seems to work on its own, and the old card used to work paired with a 256gb. But when together they only report half the space. Another thing is that the new card on its own reports a slightly higher capacity than the new card paired with the old card.
