Cannot Flash ROMs from 32GB Sandisk

Hi,
I searched around but can't seem to find any help with why I can't flash ROMs from 32GB cards. I've tried it with a class 4 Topram card then after I returned it I tried again with a class 2 Sandisk . Everytime I load the bootscreen for it to search the root of the card for leoimg the screen just flashes and continues to bootscreen without finding the ROm file.

May I suggest you try a maximum size of 4GB microSD card and format it with FAT32.
I honestly couldn't reproduce the threads right now, but I seem to remember reading about this issue before, concerning both 8 and 16 GB cards - So it seems logical it would apply to 32 GB cards as well. I don't know whether this is related to memory addressing issues or some other limitation - FAT 32, perhaps? (please, someone enlighten us both if you know) but using a 2 or 4 GB Card prevents the problem from occuring altogether.
as above said, most 16gb cards don't work(only know one person who has said the successful y used a 16gb card) and many 8gb cards don't work, so its a safe bet that a 32 is not gonna work. 2gb seems to be the optimum size, but 4 should work too.
for me, i have a 512meg card i use on the very rare occasions i use sd.
well since I got my HD2 I've used its 16GB sandisk to flash ROMs to the phone and have never had an issue before but both 32Gb cards I've tried just don't seem to respond.
Thats rather strange.
Theoreticaly you should only be able to flash from SD cards. During booting a driver is loaded so that SD HC cards can be read by the phone.
i.e. everything non SD HC up to 4GB should work fine, everything SD HC above 4GB should not allow flashing.

My Sandisk 16GB SDHC card also works perfectly for flashing on the odd occasion that I use it for flashing that is
hmm, that is interesting, I can't flash from my sandisk 16gb, class 2. Not sure why others can.
I can flash from 8gb class2 and below though. I use a 2gb sandisk just for this purpose.

[Q] About micro sd capacity and cmw

Hey guys i was wondering if there is a limit on cmw about the micro sd capacity because i am having trouble mounting my 8gb memory on it i been using a 2gb one to flash and everything because it's the spare one i have and it's working without trouble but of course i don't like changing the sd card all the time i want to flash as the back cover is starting to get kinda lose because of all the times i pull it off yesterday and that sucks.
any help appreciated.
With CMW I've used 4gb, 8gb and 32gb in my Ray and 8gb and 32gb in my x10. I don't think it's a CMW limitation unless it's a specific version of CMW that limits, but I'm thinking that's not it.
Have you formatted the 8gb card in the phone to see if that helped?

Xperia Ray card slowdown

I have an Xperia Ray with a broken SIM reader that I wanted to reuse as a media player.
The bootloader is unlocked and it is currently running AOKP Kitkat.
Everything was working well with a PNY 64GB Class 10 microSD but when I transferred exactly the same files (about 50GB of music) onto a Sandisk 128GB Class 10 microSD the device is so slow it is unusable. If the Sandisk card is blank then the problem doesn't occur. Both cards were formatted in the device and are working without problems (full and blank) in other Android phones.
Is this an issue with Kitkat or the device being too old to properly use the card? I have already tried the unofficial Marshmallow ROM but once the microSD is inside, you cant take it out to put files on it and I had a really unstable USB connection so I couldn't use that method either.
How can I get the larger card working smoothly in the Ray?
Thanks
