I have a Micro-SD card which I keep permanently inserted in my MacBook Pro using a nifty Mini-drive. I doubt it should matter, but this is a 13" early 2011 MacBookPro, running High Sierra (hardware doesn't support upgrading to Mojave, and app store actively prevents it).

Since I use this as my long-term "tepid" storage (not disconnected "cold" storage, but not using space on my more actively used SSDs), I would prefer that it be mounted in a manner where it cannot be ejected from the OS, either through Finder, or Alfred or any other means.

Is there a way of flagging the device, through Disk Utility, fstab or some other manner, to do so? Essentially, for it to behave like a permanent/fixed disk, as opposed to it being removable?

  • It will patch the OS to run on your hardware, just check that your hardware is compatible with the patch

  • Good question! +1 I'd like to know if there is a flag or such that could be set, as I too find the need at times to keep a drive from being ejected. What I typically do is open a Terminal window that has been cded_ to the root of the external disk, which then typically will not be ejected until that Terminal window is closed. Not an ideal solution but at least a workaround. Dec 25, 2018 at 18:12
