I recently upgraded the hard drives in my home server. Its an Intel D945GCLF board, which is part of a Tranquil PC I bought ages ago. Its running Windows 2008 Server R2 as a DC. I have two hard drives mirrored using dynamic disks (yes not ideal, but considering what it does its fine).
Anyway, to copy my data across locally took AGES. I mean ages. On file copying it seems to slow right down to about 10MB/sec.
Once I got the mirror up and running, the resync runs fine at a reasonable speed. I do seem to remember a while back Agent stuck something up about file copying in Vista but I can't find it. Any one have any pointers?
If it were I/O errors with the hard drives I would expect the mirror resync to take over a day. But it didn't.
