Backup of C: disk to My Book World (ie large file) transfer is very slow eg. Backup of C: to FreeAgent GoFlex drive on USB 2 connection takes 36 minutes Backup of C to My Book World on Ethernet has never completed, estimated completion time circa 18 hours This problem would not seem to be a function of the network or the disk as a Windows XP machine backs up in a reasonable time (44GB in 2hr 43 mins as an example) on the same network. Scanning the internet suggests that the problem is widespread, but suggested solutions seem to have a very limited (in terms of results for users) effect. One feels that there is a solution waiting to be found!! Any ideas welcome, please ask for any additional information.
