iPOD and SDHC – SDXC cards

iPOD and SDHC – SDXC cards


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.

For many years you could buy SD-CF adapters but they would not work in the iPOD. Most of these convertors required a high working power supply current that the iPod was unable to provide, while others just did not provide the correct True IDE functions.

The Good News

Recently a user let me know he had succeeded in getting a 64Gb SDXC card working in my iFlash with an SD to CF adapter.
So after some investigation and spending a small fortune on various SD – CF adaptors I noted that there is a new generation of pcb design used in these adapters which seems to work well with the iFlash and the iPOD. Even better it works in all the iPod generations supported by my iFlash – 5g, 5.5g, 6g, 6.5g, and 7g.

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-Bundle product page.

    Saying its playing while not actually progressing from zero usually indicates hard-drive problems.
    But then it wouldn’t play through the dock either.

    Though that sort of issue can be erratic, where some files will play and some won’t, so could it just be coincidence based on which tracks you played in each case?

    The other possible problem is if the ipod keeps thinking the headphones have been pulled out of the socket and so automatically pauses. Due to a faulty headphone jack. But that would put the ipod on pause, rather than saying its playing while not doing so.

    Meanwhile, I’ve given up on the Kingston card, as even using a different PC it rockboxes slightly better but still won’t let you copy much to it before losing the drive again.

    That doesn’t make any sense. Why would it play fine when connector to the 30-pin dock cable and then not work (track won’t progress in time) when connected to headphones.

    Thanks for responding! The ipod shows the file is playing, but the time never progresses past zero. I can play any files through my car or computer, however.

    @Pete H – you mean they are playing but no sound through the headphones? you get sound ok when playing through your car system? If so more than likely the headphone jack/hold switch assembly has probably failed, replacement are quite cheap and easy enough to replace.

    Hi, I recently purchased a 5th gen 30gb that would not play files. I installed the iflash with a 128gb card and the ipod took 70gb of files with no problem. However, ipod still will not play files. It will play them while connected to itunes or my car, but not with headphones. Do you think the logic board is caput? Thanks for any and all input!

    Update on my trouble with kingston card – weirdly, I can install rockbox on it if I use a different, linux-based PC. But any attempt to write to the ipod with my normal PC and it fails very quickly. Have to suspect there is something _really_ peculiar about the USB on my main PC, as it seems in general very fussy about what it will work with.

    It won’t sync any Sony mp3-players, it won’t reliably synch an ipod with more than 160gb and original firmware, and it won’t write to an ipod with a kingston card. It _will_ synch to a rockboxed ipod with a PNY card, and it _will_ sync an original firmware ipod if 160gb or less. Lord alone knows what’s wrong with the wretched thing.

    Thanks – will definitely be checking to see what you find, will give me a clue whether its worth trying swapping card into different ipod.

    @Pete – it is possible that you have an issue specific to that iPod. I own the Kingston 256Gb card myself if I need to sync & restore in the next few weeks, I will try to test Encore/Rockbox on it before I do.

    Received the new U3 PNY in 256gb & 128gb versions excellent cards, and currently very cheap, sadly another USA thing.

    Well, the 128gb (probably fake) Kingston did not work… random skipping and freezing occured after a few mins of playing.

    So i ve bought a Sandisk 64gb UHS1 and its really great. Sorry for the first misinformation.

    I tried a couple of different versions of emcore – the normal unmodded one what worked fine with the PNY card ipod, and also one I think I got from beyondwind’s site.

    Sometimes it fails when installing emcore, more often it falls over part-way through installing rockbox itself. Always it continues to detect the ‘device’ but suddenly decides the device has no drive in it. OF allows the drive to be filled and seems to play everything perfectly well.

    Annoying in that before I wouldn’t have cared as I hadn’t gotten used to rockbox, but now I’m a convert and don’t want to use the original firmware! Not least as some of my digital stuff is in ogg format which OF can’t natively play. Rather wishing I’d just got another PNY card from the US, but I didn’t want to wait that long for shipping.

    I suppose there’s an outside chance its something odd about this particular ipod rather than the Kingston card brand.
