Hi there, not sure if this is the right place to answer this question.
Gutted to know that the amount of storage lost on a 400GB Sandisk Card was close to about 32GB. Of the 400GB capacity, 366GB formatted was available to store files. I found this out by multiple people and by putting in the adapter to my computer. I also realised the read/write speeds were slow but acceptable and comfortable for normal use. Later, I put the SD card into my phone (Xiaomi Redmi 5 Plus at the time) thinking it would work without an issue. Well, it did. In fact, it worked even better. Read speeds were close to the advertised amount at almost 100mbps and the write speed was just under 50mbps so I was happy. I also came to realise that the formatted capacity on my phone was showing as 394GB instead of the 366GB most people get on their computers.
I now move phone to the Razer Phone, as soon as I pop the SD card into the phone, it asks me that it needs formatting to a compatible format I believe as the 400GB capacity may have been too large or in the wrong file format. I haven't done so yet since there's about 25GB of files I want to keep (transferred from my previous 32GB card).
So I couldn't find the answers online for these two questions.
1) Why was the formatted size different on a computer, and on the Xiaomi?
2) If I were to format the SD card to a compatible format, I'd lose out on a lot of storage due to an unused partition. Correct?
Any responses are appreciated.
Thanks a lot
