Hi guys! Ok I tried 3 days now and i'm getting more and more frustrated and angry: I bought a late 2013 imac some days ago. Since the Windows 7 Install on this machine won't use the fusion drive and is stuck on the regular hdd, i thought: Well, you've got that nice Samsung Evo 1TB in your late 2009, so why don't just grab that one, plug it into your new imac via usb (with an icybox external usb 3.0 enclosure) and install windows7 on that. Here's where the problems started: The SDD had it's "normal" speed in my late 2009 imac. Well, not Sata3 because the older mac can only do Sata3 but anyways. Since i've been playing around with installing, formatting, partitioning the drive over and over, i'm now at about 150mb/s sequential read/write. That's the same for OSX as well as for Windows Benchmarks. wtf??? Second problem is, i never got to run windows7 on that external ssd. Winclone won't work (disk doesn'T show up in bootmenu. has bootcamp be to be present on that disc so that winclone can work?) and when i try to move my windows7 bootcamp from the internal fusion drive via the samsung migration tool, the external drive shows up at boot, but the prompt keeps blinking a little bit too long (about 3 secs, should only be half a sec as i know it) the windows logo is missing from the next screen where it says that windows is loading and after that i'm wondering why the next screen shows this little green bar that can be normally seen if you are actually installing windows. After that -> BSOD and reboot. Another way i tried: a fresh install from an external dvd drive with an original windows7 dvd. i don't get very far with that: when choosing language country etc. on the first screen it won't even show the mouse cursor and just locks up. Btw, Running Samsung Magician to find out more about the SSD and/or to make a secure erase won't work because, you can guess it already: Magician won't find the SSD but that seems to be a common problem. Another thing: Sometimes i get the automic play thingy in windows 7 which is triggered when the ssd is plugged in. but the ssd IS already plugged in. Same thing for OSX where it tells me that i removed the drive and plugged it in again ?? HEEEEEELP Please !!!!!
