Urgent! Android devices in the SD card in the windows of more than 100M write data appears parameter error?


As stated in the Android device SD card (2G) connected via usb cable to your PC, write small data (10M) there is no problem in windowsXP, windows7, but it will prompt written 100M data parameter error, or IO device error, which is why ?
As a comparison, also connected to Linux, but this problem does not occur, 100M's, 1G of data can be written into it.
Will Andrews who did the SD card driver, and have not encountered such problems, how to solve?

The landlord, do you say:
Android running on the computer program to the SD card Android devices write data.
In the Windows system, 100M data will make a mistake?

No, refers to copy data to the SD card (such as direct drag files, folders on the SD card), small data (50M or less) can, but try to use more than 100 M, there will be problems. Card is not a problem, because with a card reader for reading and writing is normal.

may also be concerned with the equipment, but may wonder why on Linux, Windows and Linux do not know the USB Mass Storage Device driver writes what is the difference.
