I went to the Seagate site and found an updated driver (at least I assume it is updated - it is unclear). The NTFS now mounts.

I think Disk Utility misses a proper EFI partition at the beginning of the disk. If you don't want to completely erase the drive you should be successful following the steps below: Open Terminal and enter the following to get an overview: diskutil list The 3 TB disk is your external disk. In the next steps I assume the disk identifier of your external ...

Turns out this is symptomatic of a SATA cable issue. Seems like writing to the drive was fine (hence installing wasn't an issue), but reading from the drive was causing the issue. Verify and Repair disk in the installer weren't picking up the issue. Replacing the SATA cable fixed the problem.

You must have enabled FileVault, therefore your disk this encrypted, you go to: System preferences / security and privacy / FileVault. if enabled it so you disable, it should take some time why he will decrypt your disk, then restart and everything returns to normal. for more information: https://support.apple.com/en-us/HT204156

You can upgrade the storage in your MacBook Air–but it's more difficult than your average notebook. Your MacBook uses a solid-state drive over a proprietary NVMe bus. Because there's virtually no extra space in the MacBook Air, you'll need to buy special compatible storage from a company like OWC. Following this guide from iFixit you can then replace it. ...

Folder with the question mark usually means "no valid device to boot from". Try to boot to recovery (if any exists) by keeping pressing command + r when turning on the Mac. You should be able to reinstall it there. If still fails you may try Mac OS X internet recovery (cmd+option+r keeps pressed while pressing power button) If still fails, get someone ...

Your MacBook Air (13" I presume) does not use a standard SSD drive in the 2.5" form factor that many others do. Instead it uses an SSD with a bare SATA connector on the end. It looks a bit like a standard memory DIMM. I generally buy upgrade parts for my Macs via Other World Computing. there are others that are just as good, if you prefer, but this SSD ...

Before you trash your drive, it is also worth restarting the mac. Sounds simple, but first boot after an OS upgrade or with a failed disk mount due to timing problems, and the system can get confused. A reboot sorts this out. Happened to me: disk utility couldn't erase or reformat, tried all of the above, including macissues' bash script for overwriting ...

Often I find it is mds that is preventing me from unmounting a volume. sudo killall mds And then (quickly) try ejecting the volume again. In my case, I am mounting another Mac's main volume on my current Mac. I don't want to disable Spotlight as I want indexing to resume when the external volume is returned to the other Mac (as its boot up volume).

Part of the issue is that low priority I/O now seems to get throttled heavily (or so fs_usage tells me - if you run fs_usage and look for backupd, you can see it getting throttled). So if you have a ton of files, just the time it takes to do the i/o takes forever, even if the files are small (because it performs a bunch more i/o operations around xattrs/etc ...

There is an application that comes with your Mac (in /Applications/Utilities) called Boot Camp Assistant. Launch that and follow the instructions provided on screen. I am guessing that you have a disk image file of the Windows installer on your computer. If you double-click on it it will open up into a virtual hard drive. If that is the case Boot Camp ...

Part of it might be a setting in your energy saver settings that allows hard drives to sleep if not in use, you could check on that setting and see if adjusting it makes the job easier and searches quicker. A USB 3 drive (assuming it is on a USB 3 port) should be plenty fast enough to handle the necessary bandwidth. What might be slowing you down is the ...

Boot Camp Assistant partitions the HDD so that Windows can be installed. Windows does not support Core Storage, hence the partition is solely on the HDD.

Windows' Disk Management has overwritten the GUID partition table with something unknown. This usually only effects the partition table but not the content of your disk (though it seems to be gone)! A proper GUID partition table has to be restored. The particular obstacle here is: the OP neither has a thumb drive nor a second Mac. Preparation: Backup the ...

If you can't back it up on OS X, then back it up on Windows. Then format it something else other than NTFS, as OS X doesn't officially support it. If you re-format it using Windows, you can choose the default FAT/exFAT option.

First of all i would use a gparted livecd/usbstick to find and destroy the missing partition, after deleting the misscreated partition i would left the space unformatted.

In my case it was iCloud synced photos from Photostream. Even though I had since turned Photostream off in iCloud preferences and my iPhoto library was being stored on an external hard drive there was over 80GB of space being taken up in my internal hard drive by old synced photos. This was on my mid-2007 Mac Mini running OS X 10.7 Lion, by the way. More ...

From help.cleverfiles.com How to Uninstall Disk Drill What’s the correct way to uninstall all the components of Disk Drill?

So for this type of system-level software, dragging the app ...

You can tell Spotlight that it should never index that drive and then you won't have to worry about it. In the 10.11 System Preferences there's an entry for 'Spotlight', which has a tab named 'Privacy'. Click '+', select your drive, and you're done. Just close System Preferences, wait a few seconds for the system to notice the update, and you should be ...

If you're only using files not bigger than 4GB and a drive smaller than 2TB, you can go with FAT32 (which also works on Windows). Otherwise I'd go with exFAT as well, but sometimes Windows gets problems writing to that as I experienced.

You can use exFAT but you may have to install the packages on Linux. Probably along the lines of: sudo apt-get install exfat-fuse exfat-utils This has the benefit of read/write in Windows as well.

There's no such thing as "Built for Snow Leopard". That labeling just an old habit PC manufacturers have for Windows, but it doesn't apply to Macs at all. If Apple lets you run the OS, that means they tested it, and should work just fine. The reason you can't resize those disks is because they are formatted as "ExFAT", and OS X doesn't support resizing ExFAT ...

Convert to the internal drive, and as movies are converted, delete from external, and move there. If your drives are getting this full, it's time to consider an update. 3TB externals are sub $100.

If Disk Utility (booted to Internet Recovery Mode) can't repair the error, there is nothing else than booting to your main volume, backing up everything to an external disk and after rebooting to Recovery Mode deleting the Logical Volume and re-adding a new one.

This was (or obviously still is in VirtualBox 5?) a known bug of VirtualBox 3 which should have been fixed in 4.0.0! The workaround is disabling the use of the new async I/O code... done by ticking "Use host I/O cache" for the SATA (and SCSI) controllers.

You can use an external hard disk formatted with HFS+ as a Time Machine target for several Macs without problems. Time Machine itself will make sure that the data is not getting mixed up by using the name of each Mac as part of the path.

For what it's worth, I have this setup running in a few locations with a single NAS, and multiple machines backing up to it.

If you make two different partitions in the external HD, you can easily have the two different Time Machine backup in the each partition.

Then the Mac would know which partition to use for its backup the next time you connect the external HD. The same goes ...

Long story short: the white drive represents a "removable disk", and the orange drive represents an "external disk". Think of a removable disk like a thumbdrive, something small that people would usually throw in their pockets or carry around on a regular basis, or in your case, an external SSD. An external disk is usually the exact opposite of the ...

I just started having this exact same problem with my FreeAgent Go drive which has always been working perfectly.

On El Capitan it is not possible to get an UUID for an NTFS drive and even mounting the USB drive with RW options will still make the drive in Read Only mode. I have used a solution from this link which helped in my case: Write to NTFS-formated drives on Yosemite

Yes, you will be able to partition later. When you partition, both partitions will be encrypted with FileVault. Alternatively, you could just set it to encrypt your El Capitan partition, it won't make a difference.

In my opinion the Apple_Boot partition (name: Boot OS X, size 134.2 MB disk identifier disk14s3) on the 3 TB hard drive prevents OS X from creating a Recovery HD and subsequently the installation of OS X fails. To allow the installation of OS X the partition has to be removed. This probably works: Booted to Internet Recovery Mode and after opening Terminal ...

Well first I would ask you: why in the world would you not want to back up your internal drive? Second, you could easily set up Time Machine, but simply add the internal drive to the exclusions.
