I recently had the same question and found a command line tool www.smartmontools.org which can be installed via brew: brew install smartmontools you can then run it smartctl -a disk0s3 for the full report where disk0s3 is the disks physical backing which can be found in Disk Utility.app by getting info on the drive. (There must be a way to find this ...

Aside from the speed issues that other people have mentioned, you will quickly kill your thumb drive. One thing that differentiates thumb drives from SSDs is the sophistication of their wear leveling algorithms, the amount of over provisioning of sectors, and the availability to integrate their garbage collection with the host through TRIM commands. ...

Place a foot in the door. On each of your disks, create a text file, open it in TextEdit, add some line, and leave the file open unsaved. I think this trick will prevent ejection. Test this trick, try to eject the disk and come here tell us the result. This trick can easily be automated.

It would seem that the drive is no longer "blessed". First, try booting the Mac while holding down the option key and if the drive is in the list of boot devices then selecting it once will "bless" the drive and you should be able to boot off it once again. If that doesn't work then boot off the bootable hard drive you mentioned and run Disk Utility which ...

If you are facing a healthy file system at the level of its structure and want to find files which have disk faulty blocks, here is how I would proceed: Make a full backup of your disk with Time Machine or Carbon Copy Cloner Check this backup. Run the following heavy and risky (in case you do have bad blocks outside of your filesystem structure) command: ...

It won't boot, building a hackintosch machine takes more effort than just swapping a hdd. Macs have a different bios than windows pc's and this is not stored on your hdd but in the machine itself. Osx needs this special bios to run and "talk to" the components of your mac. Also, osx might not have the drivers available for the components in your pc. you ...

If only the arrow comes up when you hold down option it most likely means there's some kind of hardware issue. You may be able to repair it using the Disk Utility in Internet Recovery (Hold down ⌘ command+⌥ option/⌥ option+R while booting) , but I'd advise in to looking to getting this thing serviced or repaired. Sounds like you've got a bad HD. If all ...

Yes you can repartition without losing data. Using Disk Utility, perform a repair on your drive to make sure the drive is free of errors (even better, use Diskwarrior if you have a copy). Then unmount your drive but don't eject it. Select the drive in the left hand pane, then go to the Partition tab. On the Partition Layout section click on the "+" to create ...

If it's every time you log in, it could be in your login items. Check System Preferences → Users & Groups → Login Items for links to those volumes.

Reboot in single user mode by holding the Command + S during boot. When you see a prompt (should look like root # or something similar), type fsck -f and press Return. This is Mac's built-in filesystem consistency check tool and allows you to find and repair errors with the startup file system. Run this command until you don't see **The volume [volume name] ...

You are likely doomed. The store gurus will go over data recovery options and explain they don't fix damaged drives, they are simply going to ask about the status of your backup and whether you want them to test the operation and see if it needs to be exchanged under warranty / AppleCare. Some things to try on dead and near dead drives include putting ...

Step 1: Stop doing anything with the computer. Anything you do will likely make the situation worse. Step 2: How much is the data worth to you? It sounds like your drive had a mechanical failure. In this case, your best bet for recovery is to send it off to a professional data-recovery company. This will cost you about a thousand dollars, and they ...

As long as the drive connects to your MacBook Air via a connection protocol that the Air supports like Thunderbolt or USB 2 or USB 3 you can format the drive and use it with your Mac just fine. To format an external hard drive on your Mac (paraphrased from here): Connect the drive to your Mac Open Applications > Utilities > Disk Utility On the left ...

I highly recommend completely backing up the machine before attempting this, either using TM with no exclusions set, or better yet, cloning the whole drive using a program like Carbon Copy Cloner. Unmount the Logical Volume: sudo diskutil unmount force /dev/disk1 Remove the Logical Volume Group and all of its contents: sudo diskutil cs deleteLVG ...

If your important external drive is mounted on the following mount point: /Volumes/important_disk Then you can protect it against an accidental removal by locking this mount point as opened. For this one very simple method consists in opening Terminal and doing this basic command: $ cd /Volumes/important_disk To get rid of this locking, you might type ...

According to this page: http://support.apple.com/kb/PH11102 If the Encrypt checkbox is available, you can select it to keep your backup disk secure. If the Encrypt checkbox is dimmed, your backup disk doesn’t support encryption. Encryption is available only for Time Capsules and for partitions or disks attached directly to your computer and ...

I have had the same issue. If you have an entry for the drive in your Keychain, delete it and try again. To do so, open Applications » Utilities » Keychain Access.app and look for the Encrypted Volume password. Delete it from the list. Eject and plug in the drive again. When it asks for the master password check the 'remember' button.

The backups are stored in a hidden volume called .MobileBackups. These are Time Machine's local snapshots. They are separate backups that save previous versions of files for cases where your Time Machine drive is not available. You shouldn't modify the contents of this volume directly, and therefore it is usually not visible in most cases. You can disable ...

Every time an application access a files on the HD, it will start itself. Sometimes it can be a background process who does this, that's why it may happen although you don't access a file directly. You can watch this with this command : lsof | grep "/Volumes/HDName" lsof lists the files accessed by the all process. The grep selects only the files located ...

You can also use opensnoop for a 'live feed' of accessed files: sudo opensnoop | grep "/Volumes/diskname" Run the command, then use your computer. When the drive starts up, look at the Terminal window to see the log.

Recommending specific brands and models can be tricky (and this list will probably be out of date in weeks), but at the moment some of the SSD models that get positive comments from Mac users include: Samsung 840 Pro series Samsung 840 Evo series Crucial M500 Sandisk Ultra Plus As long as the drive doesn't require any additional software to be installed, ...

I've struggled for some days with the same problem but now it is solved. The problem was a faulty SATA cable. I've replaced it with a new one and now everything works as expected.

Apple's bespoke command line utility to do disk cloning is asr. It is tailored to the specifics of OS X needs to perform file by file as well as block based imaging and deals with differences in partition sizes, allows network streaming (and even multicast streaming) as well as copying between disks that are locally connected. Unlike dd, it knows about ...

To access the previous backups, press the option key when clicking on the time machine menu bar icon. You'll see an item to browse other time machine disks.

Your partition table does not know about the larger hard drive yet. While Disk Utility also queries the hard disk size and lets you request it to enlarge your partition, it will fail when finally changing the partition size (after doing a file system check). This can be solved on different ways: One is to destroy the GPT (partition table) and recreate it ...

I also have this issue... MacPro, 3TB drive (Seagate). I have to use the terminal: diskutil list diskutil unmount /dev/disk22 diskutil eraseDisk HFS+ "Macintosh HD" /dev/disk22 etc etc to utilize this drive correctly. (Sorry for all the commands. Posting them just in case it helps someone. Though anyone using those commands better know what they do ...

possibilities. A: Unmount the disk from the command line. diskutil unmountDisk Lacie would be the command to unmount a disk that has a file system named Lacie on it. You can also refer to the device itself, but devices can vary from one mount to another. unmountDisk will take any file system name as the object but will unmount all other file systems ...
