confusing about reformat SSD for ML clean install

Post by Sash » December 7th, 2013, 9:27 am

Hi everyone

I need your help please in this one:

I have a used SSD drive on my PC (SATA III) with Win 7 on it, & I want to use it into my MBP late 2012.

to do this, I need to swap it into my mac, & perform formatting..then install ML 10.8.5 on it (I have it on bootable USB).

in order to do proper format, I googled for the proper way. & I end up with two ways..which really confused me:

within disk utility..& after choosing the drive name on upper left pane:

- some will choose "erase" tab..then journal format type..name the new drive..choose "security options" then hit "erase" button

- some will choose "Partition" tab..format as journal..name the new drive..choose "1 Partition"..click on "Option"..choose "GUID Partition Table"..ok..then "Apply"..then "Partition".


my two questions:

1) which method of the two above is more accurate for a used SSD?..& why?

2) since this is used SSD, I read in some web sites that we should do "One Pass" erase stage in "Secure Erase Options"..so I can retrieve my SSD to manufactory clean cells condition (if you understand me well)..thus making it super speed again.is it true?..or just doing fast erasing will be enough?.

please I need your experience in this.

Well, It’s been a while since I worked with an SSD but I treat them no differently than HDDs or flash drives. As rule I will first partition with a GUID Partition Map (necessary if the drive is ever to be used as an OSX boot drive), format it as HFS+ (journaled). I don’t know about doing a one pass secure erase speeding things up, but I don’t think it would do any harm, so go for it.

I'm pretty sure ML will create the recovery partition without you having to do anything special, but it has been a long time so I don't recall the particulars.

I may ignore the one pass matter..& continue as usual in installation..Hoping thing will not effect my used SSD.

just to spread this out, I just located a useful site that talking about "zero out data" (as one pass formatting)
