    Default Huawei Ascend G300 extSD Mounting Problems

    Hi there,

    I was hoping someone could give me a bit of advice regarding some issues I'm having with my smartphone and an external SD card. I've recently bought a new SanDisk microSDHC card from Amazon to use in my phone but I keep having problems with it staying mounted. I've made a list below of what's been tried and what I think but I'm not much more than a novice when it comes to SD cards so I really would like a more expert opinion. Also, I know this particular subject has had it's fair share of limelight but I thought it's worth a shot asking anyway...

    -Phone is rooted Huawei Ascend G300 with stock B936 ROM
    -SD card is a SanDisk Ultra microSDHC 32GB Class-10 UHS-I Memory Card
    - Keep getting the notification 'SD card unexpectedly removed'. That's then followed either by the SD card re-mounting itself or the phone re-booting itself.
    - The rate at which the SD card unmounts itself varies alot. Sometimes, it could be hours between unmounts or seconds.
    -Have tried formatting to FAT, FAT32, splitting into 2 separate FAT32 partitions etc
    -Have tried erasing all data on extSD card and even factory-reset phone (I did that because someone from the Vodafone Tech Team suggested it might solve the issue and I don't keep much more than apps so it's no big deal)
    - I've read that there could be a hardware problem with the phone (apparently it likes to revert to internal storage randomly) but then I've also read that this particular SD card is not very consistent in it's quality (check forums and Amazon reviews)
    -If it's a hardware problem, wouldn't the unmounting occur regardless or the firmware? I never had these problems with Gingerbread on the exact same phone
    - Previously bought the equivalent 64GB SD card from SanDisk. It later developed similiar mounting issues and soon died (I know this sounds contradictory to the previous point but with the 64GB, it was really a case of 'working, then not working'. The 32GB is less consistent in it's mounting issues)

    I'm considering returning the card for a different brand as the card's still in the return-date. What would be your personal favourite alternative to SanDisk? Plus, I ran what I suspect to be a fake 256MB SanDisk in my phone for more than a week to trial whether it worked or not and it worked without a hitch...

    Thanks,

    Rob

    Did the microSD card come in its original packaging, or was it just in an unmarked case? If it wasn't in original packaging, there's a good chance it could be counterfeit, and therefore of questionable quality. Do you know who the actual seller is? Was it Amazon or Sandisk, or was it some 3rd party seller on the Amazon Marketplace? If the latter, again there is more of a chance it is counterfeit.

    Does it work if you plug it into your desktop or laptop? If you notice problems there, then it is likely a problem with the SD card.

    In any case, it is probably safer to return the card. If the seller was Amazon or Sandisk, ask for a replacement. If the seller was a 3rd party, ask for a full refund and look elsewhere to buy another card.

    The SD card was in it's original packaging and I bought it from MyMemory (reputable from what I can see) off of Amazon. Also, the SD does work when plugged into my desktop.

    From what I've read, counterfeiters can be pretty sneaky and still make an SD card look like the real deal, with authentic-looking packaging. It may not be the seller's fault either, since the problem may be at the supplier level. Of course, I can't be sure that what you have is counterfeit--it's just something to be aware of. I'd still recommend asking for an exchange or refund.

    Had very same problem on my G300.
    Phone was replaced to a new one due to problems with touchscreen.
    Now the new one do not recognize the SD card at all.
    Looks like solution here would be to a buy another phone of a more known brand...
