Hi, I've just got my NSLU2 from Amazon and already encountered a severe problem. I upgraded to firmware version V2.3R29 an have attached an 3.5" external disk case from techsolo (techsolo TMR-3550) which uses a Cypress chipset. In the case I use a Samsung SV1604N 160GB harddisk. I link the NLSU2-share as a network drive to my Windows XP system and start copying about 20GB of files from a local drive to the network drive. After copying between 2GB-4GB of data, the network-drive is lost (error from Windows Filemanager: "The network name could not be found"). The NSLU2 can still be reached via ping, the network-interface is usually, though not always, unreachable. The light-inidactors on the unit indicate no problems, the disk seems to be still present. The logs don't report any problems. I used the USB-drive before locally and didn't encounter any problems at all. I now have tried almost all recommendations I found in this board: removed the Master-jumper from the harddisk, plugged the USB-drive into USB-port #2. Nothing seems to solve the problem. Has anybody any idea what might solve the problem? Any help is welcome. Is the NSLU2 simply broken, is it a software-bug or might the USB-case incompatible?
