Just picked up a brand new 128GB Crucial M4 and finally came to transfer my OS onto the SSD. Now, first the copy process works but after it restarts and continues the copy process in pre-windows environment, it works some and then reports "copy succeeded" and 2 sec later throws an error: "Some error occurred: 0xC0000185." and then just hangs. All I can do is shut down or reset my PC. After this, I opened Disk Director and it displayed the SSD as unallocated space. Tried partitioning it to a Basic, Logical NTFS partition and it threw some errors. I tried again 2 minutes after and suddenly it worked perfectly. Didn't try to migrate again yet but I dunno... I need an opinion, maybe this drive is bad and I need a replacement. Edit: Tried to migrate again, epic fail, I'm getting the same error. Though, I partitioned it again after this failure and this time it worked right away.
