How to distinguish USB hard drives and SSDs from USB keys / pen drives on macOS

由 北城以北 提交于 2021-01-04 05:42:43
问题 How is it possible for code to distinguish between external USB hard drives and solid-state drives on the one hand versus USB sticks on the other hand? I'm not familiar with macOS APIs (or system calls, interrupts, messaging, and other things) but I'm guessing it would be in I/O Kit or Disk Arbitration? On the Terminal command line you can use system_profiler SPUSBDataType and see this information listed under "Removable Media". 回答1: You can get the removable/ejectable information directly

Programmatically retrieve an OS X disk partition UUID

问题 I have a path to a partition. How can I retrieve UUID of that partition programatically without using terminal commands? An example will be more helpful. 回答1: You can use the Disk Arbitration framework (Apple reference). There is also a good summary at this blog by Chris Suter. You can get the UUID by using the kDADiskDescriptionMediaUUIDKey. Aaron Burghardt described it well in this mailing list thread. Here is a quote from that link: Once you have the DADisk, use DADiskCopyDescription to

Programmatically mount a disk/volume using only a given file path in Mac OS X

由 ≡放荡痞女 提交于 2019-12-07 04:58:26
问题 I have a list of file paths. These paths may lead to files on unmounted Volumes. How can I programmatically tell the OS to mount the volume before I try to access the file? I know this is possible somehow, as iTunes appears to do it. For example, if I initiate playback of a song located on an unmounted network attached volume in iTunes, the volume is mounted automatically for me. Is the OS supposed to mount the volume automatically for me if I attempt to open the file programmatically at the

How to iterate all mounted file systems on OSX

问题 I am interested in iterating all mounted file systems on OSX (currently running 10.9 Mavericks). I am looking for something similar to getmntent() or the output of the mount shell command (although I want to do it from objective C, so parsing the output of a shell command is obviously not optimal). I have been looking a bit at the disk arbitration framework, and it appears that I could be notified about mount and unmount events using this framework. I may be missing something there, but it

问题 I am want to unmount a disk WITHOUT EJECTING. To do that I tried following code { NSString *path; CFStringRef *volumeName=(__bridge CFStringRef)path; DASessionRef session = DASessionCreate(kCFAllocatorDefault); CFURLRef pathRef = CFURLCreateWithString(NULL, CFSTR("/volumes/Untitled"), NULL); DADiskRef disk = DADiskCreateFromVolumePath(kCFAllocatorDefault, session, pathRef); DADiskUnmount(disk, kDADiskUnmountOptionForce, NULL, NULL); } This code is from this question, Thanks to @zeFree Its
