Disk alignment seems to the least of my issues right now. I did use the Windows disk utility to partition the disk, choosing GPT (perhaps a mistake) with the expectation that it would align properly. (IIRC it offered options to align at 1MB ore no alignment and I chose 1MB.)
I installed Acronis using the license keys provided with the SSD. No Joy. It left the destination disk grayed out w no hint as to why.
Next step was to download and install Clonezilla on a USB stick and give that a shot. It copied all partitions except the second one (/dev/sda.) I could not get this disk to boot. Back to booting the original drive. Disk management shows it grayed out due to a signature collision.
I found a fix for that and got the drive on line ( using diskpart.)
Back to Acronis. I start up the clone operation and now it shows the SSD as a destination (not grayed out.) Disk Management also shows all partitions on the drive as healthy including the second one (a 500MB EFI System Partition.) I start the clone operation and Acronis shortly exits.
A few moments later it pops up a message telling me to restart to complete the clone. I hit the power switch and after shutdown, hit it again. System comes back up to the login screen. I repeat the operation except this time I restart. Same result.
I tried it a couple more times paying attention to every Acronis Clone message and nothing seems amiss.
<sigh>
Maybe I'll try partitioning it using the MBR scheme. GPT is probably not beneficial on a 512GB drive. No, check that Diskpart reports both drives as GPT. I noticed that after I tried the 'convert mbr' command and it reported that the drive could not be modified, telling me thet CDROMs and DVDs could not be converted. I guess I need to check the BIOS and see if the drive is marked as read only.
Edit: Maybe a rescue disk is the way to go. Fsck me! This is a Dell PC and they have their own rescue disk creator. It wants a USB drive with 7+ GB space. It recognizes a 4GB USB drive and refuses to proceed. It doesn't see a 16 and 64 GB USB key though Windows sees them with no difficulty.
<double sigh>
Maybe I should just install the SSD as a second drive and move important stiff over (VM images.)
