mshariy_8589 : 15/01/08 07:31 AM : Incident created -   I bought an external hard drive (WD My Book Home Edition 500 GB) and I plug it into USB port on my machine (ASUS M2-NE motherboard). The drive is automatically detected and mounted and everything works fine, except transfer speed is 2 MB/sec, as displayed by Midnight Commander on copying a file. If I plug in a flash memory stick, transfer speed starts at 30 MB/sec and gradually goes down while copying a large file. If I reboot into windows and copy a large file to the same external hard drive, the copying goes way faster, a 1 GB file is copied in 15-20 sec, so the speed is around 50-60 MB/sec. Since it works fast on windows, it should not be a hardware problem. Is there something I can do to improve the transfer speed? Here is output from mount, first line is harddrive, second - flash memory stick. /dev/sdb1 on /media/hd type vfat (rw,nosuid,nodev,sync,users,umask=0,iocharset=utf8) /dev/sdc1 on /media/disk type vfat (rw,nosuid,nodev,noatime,uhelper=hal,flush,uid=500,utf8,shortname=lower) Thanks, Max
