![]() ![]() Is it possible to do this from an EFI shell? I'm happy to install rEFInd or similar on the bootable USBs.Īre there nvram settings that can be changed to achieve this?Īre there kernel boot parameters that instruct OSX not to initialize or use a PCI device, tree, or disk?Īre there kernel modules that I could install that would achieve this? If so, they'd probably need to be open source so the users could audit them and make sure they're loaded early enough to not let any writes through. Those solutions all disable disks right after boot, which is not sufficient: disabling automount of the disk or hiding it from OSX's disk management does not satisfy the users' (admittedly silly) audit requirements. I've seen the solutions to this question. Next, go ahead and stop it, again using launchctl but this time. Notice it has an alphanumeric string in front of it, appearing similar to 0x10abe0.diskarbitrationd. In just a few clicks, you can use the SQL Server installer to install or download Evaluation, Developer, and Express editions of SQL Server 2016. (exceptio arbitri saying there is a valid arbitration agreement). To disable disk arbitration, first run the following command to obtain a list of currently running launchd-initiated processes: You’ll now see a PID and the name of the process. The physical port to which the disks in question are connected will not change. under this least demanding law the arbitration agreement is valid. It's OK to disable the entire disk controller as part of a solution these systems are externally booted from USB devices, and internal hard disks will not be used until they are re-enabled. When we were doing data recovery with a Linux homemade tower, we would go into the BIOS and disable the SATA port with the sensitive disks on it. Is it possible to disable all access to a disk, SATA port, or disk controller entirely outside of the OS, before the system boots?ĭisabling only read access is acceptable, but tends to be harder to verify compared to "make the computer act like the disk itself isn't plugged in". I use a mac for data recovery forensic operations, and for compliance with my users' requirements, I need to guarantee that no disk writes will be performed on a physical hard disk attached to a mac until a user enables the disk. ![]()
