Big size files not copied to USB (OTG)

[kmuland]

Hi all!!

I have a Sony Xperia st25i android 2.3.7 phone and I have the following problem when copying files to USB OTG

Small size files are copied ok (photos for example), but when I try to copy a big size file (300mb video as example) the copy dialog start but freeze after reading the first blocks of the file and I have to remove the USB drive manually. When I plug the USB again and I check the content, the file partially copied appears with 0bytes of size. It is like you cannot create this big file on target USB drive. Or maybe there are a bottleneck... maybe source file is transferred at bigger speed than the write speed of the USB drive?.

Im sure that is not a total commander bug.. and will be related to my android device, but I wanted to post here cause total commander is my fav commander of all that I have tested.

Thanks for the replies, and your ideas. I really want to solve this problem!

It could be a problem with the power supply to the USB device, writing usually takes more power than reading.

You are right. I tested with different USB sticks and someones work properly so I can imagine that they require less power to work/write than others where the writing process fails

Million thanks for the help!!!
