Your syntax is a little off. "cp egclient.jar /dev/hdc1" is copying egclient.jar over the hdc1 device, not into it. I didn't think unix/linux would actually let you do that. My guess is that it wrote egclient.jar starting at the beginning of the cf card and overwrote the partition table which is why the file system is gone. The correct syntax would be "cp egclient.jar /dev/hdc1/", notice the trailing front slash after hdc1. Though I still would not recommend doing it this way. I would reformat the the CF card, mount it and then copy it with this command. "cp egclient.jar /mnt/" Again, make sure you get the trailing front slash.

New to the group, new to the unit. At the hamcation flea market i picked up 4 units, all "broken", seems they all work to some extent. one has a broken lcd, all took the firmware upgrade. all have slightly different opotions. dissasembled and reassembled cracked unit, it still works and is useable with remote software. saw some talk of the download issues, check any/all firewall settings on the host pc as the file is pulled from the pc within the java parent. i had trouble until i used the early 1.4 java package. that worked well on xp and still works on w7. starting to look into modifying the options, i'll post results here. i will also mention that since this is an older unit, don't use cf larger than 2g due to changes in sector sizes. find a 64 or 128 MEG cf card for transfers and you'll have much fewer problems. hope that helps.

@CustomEngineerer thank you, that was useful tip, copy now in order :-+
Concerning overall progress, something still missing..... Correct path maybe?
RemoteGui.jar is not able to start egclient.jar, even not when all are within Home folder
When run alone egclient.jar makes this screen, and it is not possible to quit OpenJDK Java 6 Runtime.

Glad you were able to get the copy done. For what's going wrong now all I can think of is to make sure that you are starting RemoteGui.jar like Urs42 suggested in Reply #35. Pasting it below. Also note that the command is a little different than when he first suggested it back in Reply #29. Good luck.
--- Quote ---It loos like you are running the command in your home directory, that won't work. Run it in the directory where all the java files are.
I pasted the wrong command line, please replace egclient-patch.jar with egclient.jar
--- Code: ---java -Dserver=192.168.1.209 -DlocalAddress=192.168.1.205 -classpath "egclient.jar:xerces.jar:JimiProClasses.zip:RemoteGui.jar" elgato.gui.MainWindow
