OK, here goes. I've read through almost every post and have tried the following to get my 750gb desktop drive to copy to my DNS-321, but it always loses its connection or gives me an error halfway through. I know 700gb is a lot of data to transfer, but I don't know how else to populate this drive and keep it raid1 without it formatting one or both of my 750gb drives. I'm using it with my Dlink dir-655 gigabit router
I have:
Turned off upnp, itunes, NFS, FTP and all other servers
Turned off 'enable hibernation' on hard drives
Reformatted hard drive
Restarted after resetting all settings to factory default
Restarted router and tried again.
updated firmware twice on dns-321 and dir-655 ( now on beta 1.03 firmware and beta firmware for the router also)
used the following backup and/or clone drive programs:
Ghost 12
Second Copy
Backup Exec
Syncback Pro
MS SyncToy 2.0
All give 'cannot complete copy' type errors. I make sure I am not using any of the files and that the computer is not being used. I have run scandisk on the source drive, which copies just fine to an eSATA drive directly attached to the source desktop computer.
Any help would be greatly appreciated before I give up.
