    Hi

    I have successfully connected my mac mini to my old Windows 7 PC via ethernet, and can access all the files on the Windows 7 PC. I have an admin folder with about 300gb of data, which I want to copy over to my mac mini.

    I started a 'copy' process and after counting all the files 500,000 or so, the copying started, but telling me it was going to take 21 DAYS. Er.... what?

    I have, I think, set things up ok, but can anyone sugget why the copy process is going to take so long using ethernet (its a cat6e high quality cable)?

    any suggestions would be very welcome. Or alternative ideas for transferring the data over. I want to shut my windows PC down asap.

    A USB external drive would be better if you have one. Even a large USB stick for chunks.

    You can probably fiddle with the network device settings to speed ethernet up but it's easier in other ways.

    Another way is to use a cloud service such as Dropbox.

    What do you have connecting the two units ?
    What sort of switch ? Gigabit ?
    Have you tried rebooting everything and trying again. I find sometimes that there are old DHCP and networking settings still hanging around when attempting to connect Win to Mac.
    Is there a 3rd device you can use as an intermediary ? I always find that going Win>NAS>Mac is faster than direct. Is there a USB drive you can use ?

    I also had some problems with file ownership when re-accessing. Make sure you test this IMO.

    I second the use of an external drive for that much data. Sounds like one of your computers is not using gigabit ethernet.

    Have you tried to copy a large single file? That may show if it's really a network issue. Common problem is speed / duplex mismatch. Aside from that it generally does twke much longer to copy many files due to the overhead on each machine of opening / creating / saving / closing each file. I'd archive them first then copy.

    If an external disk is available then the other stuff really isn't worth the trouble. As others said, go that route.

    Hi all

    I went the external HDD route in the end and got everything copied over in two stages in around 8 hours. It was a lot of stuff. But I will research the ethernet possibilities a bit more.

    thanks for everyone's thoughts and help.

    21 days is way too long, like when I mistakenly copied huge files (about the same size as yours although mine was between two Macs) over WiFi and thought I was doing it over Ethernet.

    Make sure you've turned off WiFi on both computers, sorry if you have done that...
