I installed 0.686 stable (full version) on an USB stick. I have a 500Gb disk ufs formatted and exported by Samba. I have been unable to copy a 10Mb file either from XP or Vista on this exported disk. I managed to copy several Gb to the same disk on the same PC booted with Knoppix 5.1.1. The motherboard is an MSI K9N-NeoF-V2 with an nForce 520 chipset. The log files show read data failures with connection reset by peer. On the Windows side, the share has disappeared. The smbd daemon kills itself and restarts.
