It is possible, although not from Apple themselves. A company called OWC seem to specialise in SSD upgrades for macbook's and have upgrades for your model available here These particular upgrades offer greater speed and capacity to some of the stock apple SSD's from 2011.

The HDD is formatted using FAT32 which has a known limitation of 4GB file size. You need to format it using exFAT which is supported by OS X and Windows.

I would try using rsync from the command line. rsync -av --ignore-errors /Volumes/failingDrive/ /Volumes/brandNewDrive should do the trick. Mind the trailing / at the end of the source. Rsync will not copy files it finds on the destination, so if you call it a second time it will continue where it left off.

You can press the option key to change the behaviour move instead of copy between different volumes copy instead of move on the same volume

Macs Fan Control can set the fan of an iMac (or MacBook, or other hardware) to any speed. The coolest thing that it can also set a fan to sensor-based control depending on your new HDD by reading its S.M.A.R.T. temperature. This free app is much better and powerful than HDD Fan Control, which is currently deprecated but still costs $35. Macs Fan Control ...

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.

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 ...

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 baking which can be found in Disk Utility.app by getting info on the drive. (There must be a way to find this ...

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: ...

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. ...

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 ...

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] ...

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 ...

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.

Indeed, there are some differences between cloning the disk and Migration Assistant. As you mentioned, MA will not migrate all the files, which can be both good and bad… Corrupt system files won't be copied if you use MA since you are installing a completely new OS, then copying certain files over. However, be warned that since they won't be copied over, ...

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 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 ...

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 ...

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 ...

None of the HFS flavors will offer any performance benefit that's measurable. I have seen encryption slow down some storage medium such as slow USB flash and I would expect journaling there to also be more of a slowdown than on storage with fast cache or more responsive write service times. I suppose journaling could in some rare circumstances (bizarre edge ...

Yes. However you may want to look inside the folder and selectively delete old caches rather then just dumping the whole folder.


3

It's generally safe, though a little dangerous depending, to do it but often not worth the effort. The caches in /System/Library/Caches are generally small and useful, the ones in /Library/Caches are less system caches and much more readily cleared. If you have a look in ~/Library/Caches you will find a bunch of applications have a cache in there, none of ...

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.

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 ...

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.

It is definitely possible to partition a single drive into two partitions and have separate encrypted Time Machine backups on each partition for your two individual Macs. The only downside is a single point of failure since there's a single physical drive used for two machines. If anything goes wrong with that disk, both the Macs would be left without ...

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, ...
