hi

is there a good choice?

i have several hard disk ntfs (windows filesystem )  with music & photos connected

 

may  i ask you 2 questions?

 

1) does trimforce enable trim for my external hard disk ?

 

2) may i know how can i avoid to mount all my external hard disk during the  boot ? and how can mount these hard disks when i want when i use my imac  (not at boot)  ? i keep on i don't want to unplug and re-plug just if there is a command or script to mount them when i'm using my mac

 

my external hard  disks , come from windows , i have ripped several cds ,i have photos

 

thank you so much, appreciate your help

Yes, you should enable trim. This command:

 

 sudo trimforce enable

 

 

Edit fstab to stop partitions/disk from automounting:

Hello, I am visiting for another month or so, so I do not have my mac with me.  Sorry.  Going by memory I BELIEVE you can go into disk utility and mount it when you need it.  I believe you can see the disk and you just right click and mount or something like that.  

 

I have a partition on a passport usb drive I have set up not to mount and I just go into diskutility and mount it when needed.

 

You CAN also do a command line mount.  It you set it up to not mount on reboot it should still not mount when rebooting.
