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.

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.

    Just a thought for Alexander and his skipped tracks. It might be worth checking the album on iTunes to make sure that all the tracks for the specific album will play. If you get a circle with a dot in it next to a track that you are trying to play and when you click on the track to play it you get a drop down member asking you to locate the track then this could be your problem. I often have this problem with tracks ‘disappearing’ from my iTunes library and have to check my iPod library in Explorer and iTunes and finding my music list via IPod control. This is usually easy to find in Windows 10 explorer by clicking View in the top menu list and find ‘Hidden Items’ and click in the box and this shows up IPod control in the iTunes folders and the music library is in the iPod control folder. How to find iPod control on other versions of Windows can be found through google.
    Does anyone else know why these tracks disappear from iTunes
    A question from me now. I have just had to change my PC and had a Dell and this one has an 500GB SSD as a ‘C’ drive and a 2TB rotary hard drive called the Data D drive. I had to go for the 2TB drive to hold my iTunes library. The problem is that i have the iTunes software on the ‘C’ drive and use the ‘D’ drive as a remote drive to store my 1.4TB library which seems to work OK except when I try to download to an iPod. I’ve tried 2 iPods with iFlash quads and usually one or more of the SDXC cards has to be reformatted after each attempt to restore. Strangely after reformatting the 2 iPods will restore and download on my laptop and even more strangely other modded iPods will synch or autofill new tracks on the PC without any issues. I’m confused! Does anyone know how best to run iTunes on a PC with an SSD drive and a rotary hard drive. I’m currently using a remote hard drive to hold the iTunes library and this hasn’t made any difference to my problem.

    Tell me what the problem is.
    I have 3 players:
    iPod classic 7th Gen 160Gb: MC297
    iPod video 5.5th Gen 30Gb: MA444FB
    iPod video 5th Gen 60Gb: MA147LL
    After installing iFlash -Dual with two cards 256Gb SDXC UHS-I (U3) PNY Elite Performance & 512Gb SDXC Lexar Professional 633x UHS-I (U3), it turned out to be about 700 GB. Loaded on about player iPod video about 500GB about 26000 tracks. And on both players, you skip tracks when you audition. Whatever I ‘m listening to is a 1000-song playlist or just a 10-song album. Some track always misses. I didn ‘t put in the spread, but I put in behind each other. However, there is iPod such problem on the player for classic 7th. He reads all the tracks at once and doesn ‘t wake anything.
    What ‘s the problem and who ‘s come across?

    Hi, I used a Sandisk Ultra 128GB inan iFlash quad and the ipod kept failing during the restore process and eventually, by process of elimination, after formatting all the cards in the iflash I found the Sandisk card would not format and I tried every test and check that the internet suggested but eventually had to get in touch with Sandisk via their website and after photographing both sides of the card they paid for it’s return for testing wnd eventual replacement. I have had other Sandisk card which have been good in the iflash but there will always be rogue cards.
    Not sure if this helps with your query unless you are about to use the cards in an iFlash or have an issue with one. I get my cards from MyMemory and often use their own make cards as the 512, 256 and 128GB cards are very reasonably priced and often better when they have special offers on. They are worth a look.

    Has any used SanDisk – Ultra Plus 256GB microSDXC UHS-I Memory Cards with the iFlash Quad?

    Thank you

    I had the issue with my iFlash Quad disconnecting from the ribbon cable when it would fall. Simple fix? Electrical tape. Stick it to the back of the device. Simple to remove, simple to reapply. I imagine an SD card would be about the same if taped well.

    @Peter Mayhew
    I’ve replaced many back covers and, like you, have found their fixing points for the jack and lock switch to be juuuuust slightly out. I usually have to resort to filing down the lock switch plastic and/or using longer screws for the jack. Screws taken from old iPod hard drives sort of work for this.

    Which iFlash are you using? In any case, I drop a couple of blobs of hot glue on mine (it can be scraped away if you later need to access the card). Alternatively, just use tape to secure it.

    If your iFlash is a “push to insert / push to release” kind, then maybe the locking mechanism is faulty?

    Does anyone have suggestions on how to keep the SD card from popping out? My ipod was working fine then all of a sudden it stopped. I reopened the ipod case and notice the card popped out. How can I keep it from popping out again?

    I have also tried a ‘3000 and a 2000 mah batteries in an iPod with a thin back plate and I couldn’t get the back to fit either and you don’t like to try and force things as you’ve already invested too much to ruin things at this point of the build. These batteries fit in the thick back whilst still using the foam pad on the iFlash board. Has anyone else noticed that the fancy U2 gold and black, and probably others, replacement rear covers can be a pig when fitting the headphone socket and hold switch and the fixing points have to be ‘adjusted’to fit. I like using these covers because they don’t have a ‘xxGB’ figure on them so I can have whatever size of memory without trying to find a matching back. The biggest issue on these rear covers is the area around the hold switch which is always raised around the switch hole rather than being flat and the hold switch can only be operated with a finger nail which can be a fiddle when the iPod is in a protective case.

    @Lauren Glenn

    I disagree regarding the 3000mah batteries – the guide to batteries on this site fits with my experience – the largest ones, normally labelled 3000mah, won’t fit with a slim back. What does seem to happen is that sometimes those Ebay sellers from China will send a differently proportioned battery to the ones that usually have that particular capacity claim. In particular sometimes they describe it as ‘3000’ but what they send is the size of one of the ones usually labelled 1900 (which themselves seem to come in more than one size).

    Whether those custom batteries fit with a thin back or not all depends on the exact dimensions of the battery. The capacity they are labelled with or advertised as doesn’t mean much anyway (I think in reality they are all roughly the same capacity, with the largest ones maybe being 10% higher than the smaller ones at best).

    Hi,long shot but I’m hoping somebody might have had a similar issue. I have 2 different ipods, both with sd card adapters. SD cards read and work fine separately, they’re recognised when plugged into the ipod and I can start a sync. But every single time I start a sync I get a ‘The IO operation at logical block address 0x3aa1 for Disk 5 (PDO name: \Device\000000a9) was retried.’ error in windows event viewer, itunes locks up and the sync stops. Eventually I have to force quit itunes, this corrupts the disk and then I have to reformat the drive until it’s recognised again. I cannot for the life of my figure out why. The disk shows no bad sectors, dskchk returns nothing and h2testw came back with nothing. I’m running out of ideas so any help would be appreciated.

    Anyone know if it’s possible to convert a 2nd gen iPod (Firewire-only models) to SDXC or CF card? My Googling so far is telling me “No”.

    For the last few weeks we have been testing the Integral 512GB MicroSD and the Sandisk new A2 class 400GB card – which have all been working great. The Integral was(is?) the cheapest 512GB MicroSD I could find in the UK.

    As an FYI for anyone interested….

    if you buy a 3000mAh battery from eBay sellers in China, these are legit and work GREAT.

    BUT, if you use an iFlash Quad (or probably any other board here that uses micro SD cards), you can fit the 3000mAh battery and the iFlash Quad in the thin backing of the iPod. No need for a thick backing which all sellers say you need.

    That only seems to be true if you’re using the hard drive. The iFlash Quad is so thin, you can have the iFlash Quad and the 3000mAh battery in the thin profile and then all the cases you buy on eBay and such will fit just fine.

    I figured this may be obvious but in case anyone is interested…..

    I have recently tried some MyMemory ‘own make’ 512gb sdxc cards in a 7th Generation classic and although not the fastest card on the market they have worked well in the iPod. The card has recently been selling at £69.99 until they offered 10% off but put the cards back up to £74.99 though the 10% off dropped the price back to £67.49 so if you want large amounts of memory at a reasonable price this could be the way to go. (they have a lifetime guarantee which I have had to test with an non-formatting 128GB card and it was replaced without any bother) I used an iFlash quad with 3 x 512gb + 1 x 256gb and got just over 1.6tb which gives me all my iTunes library in lossless form on one iPod. When funds allow I will try 4 x My Memory 512gb cards which should give me 1860gb to play with. This is using the figures 0f 930gb from a Samsung 1tb SSD, don’t start me on how you can use 70gb to control the card.

    I concur with Craig. I put in the 512GB Samsung EVO from Amazon (official Amazon seller….) I put it in the unit and it recognized it as expected. I’m not sure if we can go much higher than 2TB due to FAT32 limitations with MBR, but when I get more money, I can go up to 2TB. If you wanted a MicroSD card for your iFlash Quad and can afford the 512GB card for $99 at Amazon, go for it. It will work in the Quad.

    I took the risk to try the Samsung 512gb micro SD cards with the iflash quad adapter. They work running stock firmware and 3000mAh battery. So far after a few hours of use all is well, and showing 1907gb available on the about page. But I think the actual storage was in the mid 1850gb range.

    I am also wondering about the Kingston Canvas select cards. Spec-wise they seem on par with Samsungs offerings, but quite a bit cheaper.
