Can you afford to spend $30?

If you can, I suggest you get one of these (two items shown, either will do):
http://www.amazon.com/dp/B00APP6694...=2025&creative=165953&creativeASIN=B00APP6694
or
http://www.amazon.com/Plugable-Dock...=2025&creative=165953&creativeASIN=B003UI62AG

Then, buy or scrounge up a "bare" hard drive (can be either a 2.5" or a 3.5" SATA drive).

Put the drive into the dock, initialize with Disk Utility, download CarbonCopyCloner.

Use CCC to "clone" the contents of your internal drive to the backup.
A CCC backup is BOOTABLE (you CAN'T do this with Time Machine) and is in POFF (plain ol' finder format) -- just connect it and go.

Spend a few bucks (not much), do what I outlined above, and you will be PROTECTED from losing your data again.

Closing thoughts….
I suspect we're going to be seeing MANY MORE postings here from users who have had "unfortunate experiences" like the OP to this thread. As slick as the fusion drive concept looks on the surface, for most end-users, underneath it's a disaster waiting to happen.

With a single hard drive -- or with "separate" (UN-fused) SSD and HDD -- if the drive has problems, it can still be possible to get the data off of it. With a fusion drive, if it fails, everything is gone and I'm not sure if most current data-recovery software will even work with it.

Even the "recovery partition" may not help. I'm going to _guess_ that the recovery partition on a "fused" volume is located on the SSD portion of the logical volume. If the SSD fails, the logical volume won't mount and the recovery partition may be "un-reachable". Not only will the SSD be "lost", but the contents of the HDD may be lost as well.

Of course, others are going to reply that you can recover from your backup. But the reality is that many (most) folks with fusion drives probably aren't going to keep backups. Simply the way it is.

The "better way" is to just maintain two volumes, SSD for the OS, apps, and user accounts -- and keep other stuff on the HDD (including movies and large amounts of music files). This will result in a computer that actually runs FASTER than a fusion drive will. All it takes is a little awareness as to "where things are".

Again, it won't be too much longer before we start seeing postings to the effect, "help, my fusion drive failed, I've lost everything, what do I do now?"….

So yesterday I woke up to have my brand new iMac froze(I could move the cursor but couldn't click anything). I shut it down and turned it back on only to get stuck on the grey screen. Restarted ran disc utility, checked and verified, restarted, still got the grey screen. Ran hardware test, came up ok. Reset PRAM nothing. Tried reinstalling Mount Lion, got stuck on negative time remaining( I let it go over night and it got to -6 hours plus). Contacted Apple Support and they just ran me through things I've already done.
Called Apple Support back and ask for a senior tech who has me running an internet recovery which I don't think I tried before. Hopefully this works, never had a problem with my other iMacs other than having to replace a HDD on an older machine.
This is so frustrating.:mad::mad:

ETA: Have Genius appointment for later today. If they can't get it to work I don't want a repair, I want a replacement.

All of these symptoms sound very familiar to what happened to me and my 3TB fusion. I have to assume that there is something wrong / going on with some of the fusion drives.

It wasn't an issue of affording a drive, I just never suspected a brand new machine would go down. Doesn't really matter now but I just ordered a 4TB Lacie that should be here friday, so future problems shouldn't be an issue. Down the road I will buy another backup drive just to be safe. Thanks for showing me the dock I will most likely do that for my secondary back up.
