AFP File corruption when copying from Share A to B

    I have also reported it (one or two years ago), don't expect any help …



    I really hope this is not the case, having spent over £2,000 on a new server/RAID setup. I now feel we should have stuck with the slower yet more reliable G5 PowerMac setup.


    E.g. you have the shares A, B and C (folders a, b and c on the RAID), take the shares away, make a new folder d and the share D and put the folders a, b and c in d.


    I'm not sure this will work for our setup, we have a Pegasus R4 RAID which has been partitioned and we share each hard drive partition over the network, we also have a separate thunderbolt drive for achived files.


    I imagine we would need to reformat the R4 to a single drive then use a folder system on the drive as you have suggested.


    I will forward this thread to the Apple support adviser I have been speaking too, in the hope something gets resolved. I'm not giving up on Apple yet, but I can see how you have after all these years.

    Not sure if it is available in Germany, but for FC there is always the Promise SANLink sn3=49


    And for other cards there is the Sonnet Echo box


    I have used the promise SANLink, and it works well, but it is too bad it is not 8Gb though.

    Only just finished testing in the last few days but I believe I have solved our AFP file corruption problem. After extensive testing and a number of reinstalls, the problem was being caused by Objective Development's Little Snitch application. This was installed on the Mac mini server and client Mac's, once uninstalled from all computers I have been unable to replicate the file corruption. We installed Little Snitch to protect the computers, but it seems to have been interfering with AFP share copies. Not sure if this helps you?

    Yes deactivating Little Snitch does not work, it needs to be uninstalled using the Little Snitch uninstall application and then the Mac restarted. The problem needs to be reported to Objective Development when I get around to it, but I can't trust their software on our network now.


    berlindude, let me know if this fixes your issue and I will report it to Objective Development

    Glad it resolved your problems as well, can't trust Little Snitch now even if they fix the problem which is a shame. I did not quite make it to a million Thank you's

    Not had time, if they have Little Snitch running on both Mac's (the server and client) they can't miss the problem as it increases the file corruption. They can't be testing properly, as removing the application solved both our file corruption issues.

    I just wanted to comment to say that I'm having what seems to be the same problem at a particular client's site. I'm pretty sure no one there has Little Snitch though, but I'll check to be sure.


    Can you guys verify that you haven't seen this behavior since getting rid of Little Snitch?

    I have not seen the problem since removing Little Snitch off our networked Mac's. I'm now very careful with installing any application that monitors network traffic.
