Theoretically everything is fine with your Fusion Drive. Fusion Drives look like this. Disk0 is your SSD with 121 GB and disk1 is your HDD with ~1 TB (~1.121 TB summed up). The larger parts of your SSD (disk0s2) and your HDD (disk1s2) are pooled to a CoreStorage LVG (Fusion Drive: disk3) with a size of 967.8 GB. The rest is reserved for EFIs, a Recovery HD ...

First: do you have a good backup? If not, make one before doing anything else. If you have one, make sure it's up to date (but don't delete the old backup history -- it's possible you'll run into other disk errors, and you don't want to overwrite your last good backup with a corrupted one). Multiple independent backups are also a good idea. Testing your ...

Yes - copying any of the folders will use the hard link to make a full copy of that moment in time. The hard links only work on the same filesystem, so you can test things if you are copying to the same volume but most instances where I do this, I'm copying to another volume (compressed disk image or physical/logical volume).

Hate to say it, buddy, but if disk0 and base system are all you got, and if base system is part of disk0, your MacBook Pro isn't seeing your hard drive.

Siting on a chair with wheels is not good, but then you can have a static discharge mat under it. Dry air amplifies the problem of static charge The key is your shoes, or no shoes. ...

You don't even need to move it to another slot. Install your SSD, set it up the way you want, then go to System Preferences -> Startup Disk and choose the SSD. This isn't Windows, and it isn't 1993. You can have as many bootable volumes online as you have disk space for, Macs boot the one you want booted.

Set your Disk utility in to Debug mode. Now you should be able to "see" the hidden partitions like EFI and the Recovery HD. To enable the Debug mode use your Terminal: Enter the following command at the Terminal prompt: defaults write com.apple.DiskUtility DUDebugMenuEnabled 1 Needless to say, there is a reason for those partitions to be hidden, so do ...
