ExpressCard SSD Time Machine & Safe Sleep issues
>One other Q, has anyone had any issues with this and Time Machine?
>Can it back up both drives OK?
Time Machine works seamlesslessly, automatically backing up both SSD and HD at the same time. Time Machine System Preferences Options even allows making separate exclusions for each drive (note for example that "~/Music" refers to Music in the home directory on the HD, while "/Users/accountname/Music" refers to Music on the boot SSD).
>Also are there any issues with waking from sleep?
The SSD wakes up from normal sleep with no problems. The only issue is a complete power drain, which Safe Sleep would otherwise recover by saving the memory image to the HD then restoring it back to memory when the AC power is connected. However, Apple notebooks are currently incapable of using anything but the internal HD for this purpose, so the system would crash in the unlikely event of a total power drain (but big deal, just reboot).
One positive of this situation is that the sleepimage can be deleted to free up precious space on the SSD. I've got 8 Gb memory in my MBP 17", so that's no longer wasted mirror-imaged on the SSD boot drive. Here's how to delete it (adapted from the following links):

1. Open up Terminal.
2. Type "sudo pmset -a hibernatemode 0" without the quotes, and hit Enter.
3. Enter your password when prompted.
4. You are now using RAM-only / "old school" sleep mode.
5. Now type "cd /var/vm" and hit Enter.
6. Finally: "sudo rm sleepimage"
7. This will delete the existing sleep image file on your hard drive, reclaiming that space for future use. You can still sleep your computer, but there's no zero-battery safety net anymore.
