Hi

 

I'm confused about what storage my Macbook has

 

I assumed HDD because the 'secure empty trash' is available.  When I go into Disk Utility there are 3 disks / volumes (Mac HD, 320gb internal SATA & Media).

 

There is the option to perform Erase Free Space on 1 and 3, which tells me that these are HDD, but what is the middle SATA one (and are files stored there)?  Is the middle one SSD?  Or if it is an HDD, why can't I perform an 'Erase Free Space' on it?

 

Thanks


*SSD

Open a terminal and use the diskutil -list command to give you a better idea of your disks and partitions.

Thanks for responding.

 

Okay, I have done that thanks.  I believe that the 'Media' is a partition of the 320gb internal SATA. The 'Media' takes up almost ALL of the 320gb.  I can secure erased free space on the Media partition.  So does this mean that my Macbook has a hdd rather than ssd?

 

Thanks

If you go to System Information > Hardware > Serial ATA it will list your HDD info.

Thank you for this,I have been able to view the model reference number and having searched it, I can see it is an HDD.  Thank you for your help!
