So bare with me. When I copy files to my USB 2.0 Stick , my transferspeed are horrible in case I mount the device with sync option, the rates are around 50KB/s, doesn't really matter how big the files are. If I don't mount with option sync, then the speeds are as expected a couple of MB/s I don't think this is the default behaviour, right? Anybody got an idea what could be wrong? Filesystem is vfat. I tried with different kernels and a live cd(knoppix), currently I use kernel 2.6.13. Motherboard is an NFORCE 4 based one: 0000:00:02.0 USB Controller: nVidia Corporation CK804 USB Controller (rev a2) 0000:00:02.1 USB Controller: nVidia Corporation CK804 USB Controller (rev a3) USB Info shows the device using ehci_hcd module Thanks in advance, Stefan ___________________________________________________________ Gesendet von Yahoo!
