Didn't work for me (I hadn't read edavid) - but it doesn't seem to matter, subjectively my mbwe is marginally faster despite no 4k alignment.
What I did:
My mbwe blue-ring single 1Tb stopped working (I now suspect the power supply). I assumed it was the disk, the nearest available replacement was Green Caviar WD10EZRX (4k Advanced format).
I got the old disk working on the DVD cables of my dual-boot PC, with a spare power supply.
I put the new EZRX on a usb3 caddy.
I ignored all the advice on copying and (double checking sdb/c!) just did:
dd if=/dev/sdb of=/dev/sdc ibs=512 obs=4096 conv=noerror,sync
after 4+ hours I got successful completion but fdisk -l reported alignment problems.
I ran gparted check on all partitions - this did nothing
I loaded the drive in the mbwe and it ran fine.
Took it out and tried to align the partitions with gparted - and bricked the drive for mbwe.
Am now repeating the dd copy.
For those wanting to just upgrade then it should work to do my straight disk to disk copy then follow above instructions to re-size partition 4 and rebuild the raid (if you want it)
