I try to copy some files from the SD card but it doesn't work, the transfer speed just goes to 0 without no error
I took it out and used a card reader...When trying to copy files from the SD card to the PC, do you remove the card from the phone and put it in some card reader connected to the PC, or does the SD card remain in the phone and you connect the phone to the PC with a cable, wifi or blue-tooth?
I've tried this and got the 121 error: The semaphore timeout period has expired, during the reading disk processUse an utility like WinImage, and read the whole card as a single .IMG file. You can then extract the files from within the image.
Yes, the card reader is good.did you try another card reader?
how did you open any file on it if you keep getting error?
OK, and how can I fix it?Your SD card is not supporting, or either it might be possible that SD card is corrupted.
Can't do that for the entire SD, it takes too much.open it from the app and do a save as
