There is a saying that nothing digital really exists unless it exists twice: if there isn't a copy of it somewhere, then the one original is in such danger of being lost that it might as well be gone already. However, this is a reason to make backups: it's not a reason to duplicate our files all over the place yet that is somehow what we do. You included. Very much you included: stop trying to look innocent. You have multiple copies of the same Word document and you've definitely got duplicated photos, admit it. Stage 1 of reclaiming space on your hard drive is admitting that you've got a problem. Stage 2 could be buying Gemini 2.0 for OS X.
Western Digital is making changes to some of its storage hardware lines, boosting the capacity to 8TB. Three internal hard drive ranges as well as some external hard drive items will offer 8TB of storage to users, 16TB for certain products that use two 8TB drives in RAID 0, with WD using HelioSeal technology to replace air in the drives with helium, allowing the drive producer to use up to seven platters in a single drive, boosting capacity.
Western Digital today announced that it is now shipping the world's first 10TB perpendicular magnetic recording (PMR) helium-filled hard disk drive. As the first 10TB drop-in ready HDD, the HGST Ultrastar He10 HDD provides the highest capacity and the lowest power consumption per TB of any commercial hard drive yet made.
There is a slim chance that you've never run nor heard of Apple's Disk Utility application. That chance decreases the longer you've had a Mac as this little app is the answer to so many issues. It's where you format new hard drives, create disk images, and where you used to be able to repair permissions if you needed to. If your Mac is doing something odd, you could run Disk Utility and have it poke about your hard drive, looking for possible problems, and often fixing them too. If you have many hard drives, such as in a RAID backup system, you lived in Disk Utility -- or you used to. Apple has radically remodelled Disk Utility in OS X El Capitan and that's got people steaming.
Last week we told you what happens when Apple recalls your iMac; in our case, pulls it out of your hands in order to do its recently-announced 3TB hard drive replacement. We also told you that if your iMac is from between December 2012 and September 2013, you should check Apple's site about this and get it sorted. Get it looked at and seen to. However, we then said we expected that this week we'd be telling you: "it came back, we signed more paperwork, we got on with our work." There was more to it than we'd expected, though, and that's only half because we went through more withdrawal symptoms than we imagined possible.
If you've got a 27-inch iMac that you bought between December of 2012 and September of 2013, go check out whether Apple wants it back. As MacNN reported, Apple has a new replacement program running to fix hard drive problems in some unspecified number of those machines. Do it now: it doesn't matter if your warranty or AppleCare is finished but you must do it now because the program will not last. You'll need your Mac's serial number and you'll need to head to this Apple support page. We did –– and right now, our precious iMac is off on a courier's van.
Roll up your sleeves, get a coffee, and watch ChronoSync backup your hard drives. Or alternatively, roll your sleeves back down and nip out to lunch, because you're not needed here: ChronoSync has it covered -- and you can look in on it remotely, with the companion apps ChronoAgent and InterConneX. This is surely the most comprehensive disk backup and management application we've seen, and possibly that nature ever intended. That does mean it's complex, but you're not going to turn to this if all you've used so far is Apple's Time Machine.
Apple did a great thing in bringing Time Machine to the rest of us: it made backups a more familiar idea, and it made them far easier to understand as well. Something that is easy and familiar is something that you're going to do, and Apple was right that we really, really needed to back up our work. Now Apple is more focused on cloud storage than it is hard drives -- and there are several cloud backup services -- but the humble hard disk has a lot of advantages. It also has SuperDuper 2.7.5, which is a capable, albeit slightly technical, application for copying your data, and for creating a hard drive that you can run your Mac from in emergencies.
Nothing digital really exists unless it exists twice. For all that we have these great interconnected cloud services, there is still a hard drive holding on to our data somewhere and all hard drives fail eventually. They're like politicians in that respect: they go on until they fail. Carbon Copy Cloner is a way to make failures annoying rather than fatal to your work. It backs up any or all of your files and it also optionally creates a separate and bootable hard drive.
In late 2013, cloud service provider Backblaze released information about hard drive failure rates used in their facilities collected over a three-year period. The study was one of the first real-world, comprehensive examinations on server-level claims of hard drive reliability, and drew a great deal of attention. An update with new information from between the end of the last study and December 31, 2014 was posted today.
