Preparing SSD for Cloning - Microman - 01-18-2015
I have it mounted and erased for MacOS Extended Journaled.
In reading Super Duper, with old style HD, they suggest Zeroing, would this be necessary as I can't see the option in Disk Utility ……. on an SSD.
And in my limited search of this topic, I heard mention of sometime called TRIM.
What is that and is that something I should or should think about.
ALSO, I have been relying on INFO to tell me how much free space and how much used space is on my current internal HD. Now when I hover over the internal drive name on Super Duper it says it has 352 gigs used, and I bought a 240 GIG SSD. Is that the recovery partition that I don't see. When I right click and get info from the current HD it says 202 Gigs used. Why the difference?
I may not have enough room

It's a item of geek discourse. Older SSD in particular may need it, but many newer drives have built-in logic that abnegates the benefit of OS-level TRIM support and provides superior performance.
So it's really going to depend on the SSD you're sporting.

ITs the 240 from our sponsor.
Receipt says Cruicial M500 240 Gig

You don't need to zero and don't worry about trim.
Re: Preparing SSD for Cloning - Microman - 01-18-2015
Cant copy 352 on 239 gigs. As per Super Duper
Must be something hidden as INFO on Internal says 202 Gigs used.
Suggestions?
Buy the 480 that was suggested for better speed, by chat person at OWC
Must be correct however, as Disk Util says that 352 gigs are used.
And partition map on this 240 SSD says GUID Partition Table, to answer question below
OH, and an interesting article:

Clone of OS Boot? Make sure it's GUID Partitioned.

Don't zero SSDs.

Migrate Music and Photos Off?
What is the extra usage from?
