Your data is the most important aspect of your computer, and unfortunately we often don’t realize this until we’re faced with the possibility of having lost exceptionally valuable (if not priceless) work. This can happen as easily as a computer suddenly shutting off on you and no longer booting, or when you attach an external hard drive containing all of your files, only to find it will not mount and cannot be repaired.

The default approach for storing files on drives other than your boot drive is to get an external storage device and then copy your files to it; however, by doing so you leave open the possibility of someone getting your drive and accessing your data. To secure the files you place on such drives, there are several approaches you can take, including encrypting files or the drive itself, and using special setups to require two or even more physical drives be attached before you can access the data on them.

When some problems such as hard drive corruption occur on your Mac, or if you need to perform account maintenance such as resetting passwords or fixing account permissions, then you will need to use the tools that Apple includes on the hidden Recovery drive that is part of OS X. However, in some cases such as for RAID arrays, you may not have a recovery partition, in which case there are several alternatives you can use, even if you are limited by your internet connection: Continue reading
Formatting an external drive to work with your Mac can be done in several ways. While for the most part drives ship in formats that are universally recognized among operating systems so data can at least be read, there are times when you may wish to wipe a drive and set it up to be most compatible with your Mac. On the other hand, you may have a drive you have primarily used with your Mac, but now wish to use it with a Windows system. In these cases, it helps to know how best to format your drive.

If you open your Mac’s boot drive, you may find a folder called “lost+found” next to the System, Applications, Users, and other system directories at the top level of the drive. If not, then this folder may still be present, but could just be hidden, so check for its presence by pressing Shift-Command-G in the Finder, and then entering “/lost+found” (minus the quotes) in the drop-down panel. If this reveals the folder, you may find a number of files in it that begin with the name “iNode” and end with a series of numbers. Continue reading
Apple has released a Flash Storage firmware update for its latest mid-2015 MacBook Pro systems, which addresses a rare bug with the hard drives on these systems that could lead to data corruption.
The update should be available through Apple’s Software Update service on relevant systems, so if you have one of these models then be sure to Continue reading
TRIM is a service that runs in your operating system and works with SSD hardware to track what blocks on the drive are unused, and then prepares them for writing. When put in use, TRIM can optimize SSD performance, especially on drives that are relatively full or used for storing and deleting large amounts of data. Until now TRIM support in OS X was reserved for Apple-supplied hard drives, but with the release of OS X 10.10.4, Apple has included a tool that allows for TRIM on third-party SSD devices.
