Audio problems with new iMac Fusion Drive

[barkmonster]

When you've booted from an external. Try these instructions to split the fusion drive, then clone your OS back to just the SSD from your external disk.

Might help, might not but it's worth a try to have a working system. If you're using for audio, assuming Apple don't absolutely screw their customers by marrying up a fast SSD with a bargain bucket 5400rpm HDD, you could actually partition the HDD as a recording drive once you're booting off the SSD.

Something like this:

Macintosh HD: 128Gb SSD.
Audio: 100GB (or whatever size you choose).
Storage: Remaining HDD space.

Thanks for a good answer. If I have an entire Time machine copy of say 500GB, what happens when I try to clone that back to the 128GB SSD drive? It wouldnt fit. I dont know if it is possible to clone back some stuff to a different destination, is it?

OSX and Application would fit on the SSD but the rest on the drive would not? What is the way to go here do you suggest?

2013 21.5" iMacs have 2.5" 5400 rpm drives. The 2013 27" iMacs have 3.5" 7200 rpm drives.

2013 21.5" iMacs have 2.5" 5400 rpm drives. The 2013 27" iMacs have 3.5" 7200 rpm drives.

I wonder if that's down to heat concerns or money grabbing?

I still have the stock 5400rpm in my Mac Mini but boot off an SSD and use a fast 7200rpm 3.5" HDD with a 64Mb cache in a Firewire 800/USB 3.0 enclosure for recording/mass storage.

Heat probably, space savings definitely.

Unless they use 2.5" HDDs in the 21.5" iMac, there's no difference between a 5400rpm and a 7200rpm 3.5" HDD. It must be heat.

Get Disk Inventory X and Carbon Copy Cloner

Use Disk Inventory X to work out which folders you need to leave on the HDD just for the OS. Large folders show up as large blocks. This is one of the problems of Apple's "easy" backup solution, it's completely inflexible.

My current OS is only about 35Gb, the rest is folders of media etc... that are backed up seperately.

What you clone back is just the OS files, Applications etc... you leave the larger folders with your iTunes library and other files where they are and then copy them to the larger HDD.

As I said above, it is 2.5" drives in the 2013 21.5" iMac.
