I have a HTC Desire rooted with CyanogenMod 7 and a 16GB microSD card.
When I copy great amount of data from Ubuntu 10.04 64 bits to this phone via USB, the speed is low (~1'2 MiB/seg) and sometimes the system doesn't respond during copy process.
It's very difficult determine where is the problem. Any clue?

  • At launchpad there are various bug reports related to this for example: https://bugs.launchpad.net/ubuntu/+bug/119325 Once I was able to fix this by installing new (Debian) kernel (that wasn't patched by Ubuntu). – desgua May 02 '11 at 14:11

    You are not alone. When writing to or reading from my 16GB micro SD card on my Android the read/write speed is slow. However, I have never experienced it stopping in between copies. It's always successful albeit slow as a turtle. One time, I was copying 5.7GB worth of data and it took several minutes (like 36min or more) just to finish writing to the micro SD card. – Marky May 02 '11 at 15:23
  • This question should instead be filed as a bug report, and [as such](http://meta.askubuntu.com/questions/1317/what-to-do-with-questions-that-describe-known-bugs/) is off-topic, thanks!

That seems to be an inherent problem of writing to a memory card connected to the computer via a mobile phone. I face the same issue with my Nokia. I recommend you to get a card reader, to get marginally faster transfers, because that is what I do.
