iFlash-Dual – uploaded some videos…

Posted a couple of videos on the iFlash-Dual, one quick overview of the board and the second is an installation video using my new Kingston 512Gb and the PNY 256Gb cards.

    @support should I send them back? is there another SD card you have good experience with?

    I’m not at a point where the missing space is a problem, per se, as my entire library in less than 170GB, I just don’t want to button it all up if these cards are sufficiently under spec that I should care or be concerned.

    @uurf – It is strange but does happen – an ideal 256GB device should format to 238GB, but with all solid state drives, during the quality check process the manufacturer identifies bad sectors, and then adjusts the reported LBA (size) of the device mapping them areas out. Hence why you do get some variation, but you are looking at an 8Gb loss from what it should be – and (in my opinion) the manufacturer should have failed that device in QC.

    I notice Kingston do this, another user in South Africa has told me his 256Gb SDA10 Kingston is only showing 231GB formatted capacity.

    The premium manufacturers like Lexar for example, they over-provision the storage so that any failed or bad sectors during QC do not impact the reported LBA (size) hence why their 256GB cards format to 238.81GB, and two installed in the iFlash-Dual nets you 478GB in reported capacity.

    @support yes that’s the odd thing; Finder and Disk Utility say the iPod (mounted as disk) has a capacity of 494.79 GB. But iTunes (12.5.4.42, just released) says 460.81 GB, and the iPod itself (in settings) reports 168GB used and 292GB remaining (460 GB). I synced 30,197 tracks to the device successfully last night.

    The SD cards are PNY Elite Performance 256 GB High Speed SDXC Class 10 UHS-I, U3 up to 95 MB/Sec Flash Card (P-SDX256U395-GE) purchased from Amazon (not a marketplace vendor but Amazon itself) in the original packaging.

    Interestingly the flash solo I installed in my son’s 6g reads much closer to the expected 128 GB installed there.

    For the 2 pny it should be more like 474. You’re never going to get the actual 512. Manufacturers never make the cards what they say they are and they’re using two different scales to represent a gb. The company uses 1000MB = 1GB but your computer reads it as 1024MB = 1GB which is where you get 474. Not sur why you are only getting 460 though. Where did you buy the cards? Are they micro sd or regular sd? I would test the cards and make sure there are no broken sectors.

    @support – I installed a dual in my 7th gen and installed 2 PNY 256 GB SDXC cards. After restore iTunes says
    “Capacity 460.81 GB”. is this the expected capacity?

    My iPod is alive again now, I formatted the cards and then restored the iPod and it helped. It was longer than I thought but it works again. Thank you very much for your help.

    @ Odonata – You can use the builtin card reader of computer or an external card reader makes no difference. Try powering up the with the iPod with no cards installed in the iFlash.

    Yes, it is always lit up with Apple logo and I can’t restore iPod, I can’t enter menu or connect to the computer, or maybe there is another way to restore it? And if I’ll have to format the cards is it important to use the external card reader or maybe I can do it in built-in card reader of my notebook?

    @ Odonata – so you are getting the lit up Apple logo? so you must have restore the iPod? Any way reset the iPod and enter diskmode, you can then connect to the computer to restore. If that does not work, then you will have to format the cards in an external card reader.
