Fusion Drive Failed

Sometimes Apple technology impresses me with it’s reliability and stability and then sometimes it doesn’t…

I have a 2006 Intel iMac, one of their early Intel models and the 250GB HDD is working well today as it did when I first got it. My experiences with other iMacs that I have used at work have been equally impressive. I once did though experience hard drive failure on one of my PowerBooks, but that was because I dropped it….

However when it comes to my home 27” iMacs I have been less lucky.

My original 2009 27” iMac hard drive failed and was replaced by Applecare, only to fail again a few years later. With this failure I ignored the drive and replaced it with an external drive. Eventually the whole system failed.

My new 27” iMac which I got in late 2014 came with a 3TB Fusion Drive. Fusion Drive is Apple’s name for a hybrid drive, which combines a hard disk drive with a NAND flash storage (solid-state drive of 24 GB or more) and presents it as a single Core Storage managed logical volume with the space of both drives combined.

Last month I came to my iMac I found the prohibitory symbol.

Mac prohibitory symbol

When you see a circle with a slash symbol instead of the Apple logo, it means your Mac couldn’t find a valid System Folder to start up from.

I did try reinstalling OS X by using OS X Recovery, but that failed…

Checking my backups I realised that there were some files missing from the back up disks, so using target disk mode (and another Mac) I attempted to recover the files from the failing hard drive. I managed to get some, but unfortunately I couldn’t get them all.

I was thinking of using DiskWarrior (which had helped with my previous iMac hard drive problems, however version 4 which I have is not compatible with OS Sierra. After a while though it became impossible to mount the drive using target disk mode. Disk Utility also failed to do anything except spin the beachball.

The other symptom I saw was the separation of the SSD from the Fusion Drive, this was not good news.

Taking the iMac to the Genius Bar, they were unable to enter diagnostic mode and using a network startup drive, were able to check that the iMac was working fine, and that the problem was with the Fusion Drive.

I had considered using a data recovery firm, but in the end with the majority of the data in my backups I let the Genius Bar attempt to re-build the Fusion Drive, which didn’t work, so they had to replace the drive with a new one.

The next step is to re-build the iMac from scratch, which is nice to do now and again, but is a bit if pain if you have really slow broadband. Really looking forward to getting fibre back in the next two months!

I know I have some missing data, but I think I have the important stuff. One thing I am now considering is getting some cloud based backup which has got a lot cheaper since I last checked it out.

I am slightly disappointed that the Fusion Drive failed after just over two years. For a variety of reasons I didn’t have AppleCare with this iMac, and it is something I will certainly consider for future iMac purchases.

Design Changes in OS X Yosemite

Apple have released a video demonstrating the new design features of OS X Yosemite.

The new OS X, currently in beta, has a very similar look to iOS 7, it is flatter, cleaner and looks very different to previous versions of OS X.

Climbing the mountain to see the lion

OS X Mountain Lion

Today sees the release of the next incarnation of the Mac operating system, OS X, Mountain Lion 10.8. It was announced back in February and back then I wrote my initial thoughts based on the announcement. As when Snow Leopard replaces Leopard, Mountain Lion in many ways is an incremental update to Lion.

OS X Mountain Lion is the latest release of the world’s most advanced desktop operating system. Mountain Lion includes over 200 new features to update your Mac into the best computing experience yet. With the new Messages app, you can send text, photos, videos, contacts, web links and documents to anyone using another Mac, iPhone, iPad or iPod touch — you can even start a conversation on one device and continue it on another. The new Share button makes it easy to share files, web pages, photos and videos, as well as tweet straight from the app you’re using. With the Reminders app, you can create to-do lists and alerts that appear in the new Notification Center. With Notes, you can write down all your ideas and even speak your words with Voice Dictation. Play head-to-head games on your Mac with friends on their Macs or iOS devices with Game Center. And with iCloud built in, it’s simple to keep all your mail, contacts, calendars, reminders, notes, to-do lists, music, photos, iWork files, PDFs and more up to date across all your devices.

There are some interesting new features, there is the continued iOSiffication and deeper intergration with iOS devices. Speech to text is now built into the OS, though as with most speech to text you will need a quiet room and I can’t see myself talking to my computer in the office, unless I can shut the door and have the office to myself.

There is also notifications, which if you have been using Growl will realise has a similar functionality, you can configure it to let you know about Twitter responses, and other messages from various applications.

Notifications Center

Finally Safari does what Chrome does and you can use the address field to either enter an URL or a search term. Countless times as I move between Chrome and Safari I have got annoyed with Safari as I type in a search term, only to have a ‘doh’ moment as I realise I have typed it into the address field and not the search. Combining the two has a few issues (for example if you want to search on an URL and not actually go there), but the advantages outweigh the disadvantages in my opinion.

One aspect of Chrome I like (especially since I got the Nexus 7) is the syncing of tabs and history, when iOS 6 is released this will come to Safari. iCloud Tabs makes the last websites you looked at accessible on your iPhone, iPad and Mac.

I do like the Share button, this is a feature I do use on the iPad so it will be nice to have it on the desktop. However having said that, with all the Facebook issues I have read about, I won’t be integrating OS X with Facebook anytime soon (nor will I do that when iOS 6 is released. Hopefully third party apps may take advantage of sharing, and embed it into their applications. I am really thinking about Firefox and Chrome at this point.

Reminders also comes to the Mac and I am thinking I might take advantage of that as it does integrate nicely with iOS. The same has happened with Notes, though I don’t think I will be replacing that with Evernote anytime soon. I like in Evernote how I can add image and audio notes as well as text notes.

There is better iCloud integration, but it still doesn’t work as I would like it to, so I can see myself staying with Dropbox for the foreseeable future.

I am not a great user of messaging services, but I think, again with the better integration with iOS that I may take advantage of it.

One downside for me is the size of the install file, at 4.05GB this is one big download and having recently switched from FTTC back to ADSL this was a very slow download…

As I said at the beginning this is very much an incremental upgrade, so I would be really disappointed to pay £100 for this, the price though is just £13.99 which is incredibly cheap for an OS upgrade compared to what we have paid in the past. Also, as it is on the App Store means that for £13.99 you can download and install it on all the Macs you own or control.

It was one of those days…

I have been meaning to upgrade my home iMac to Lion for a while now, with the end of MobileMe imminent (end of June) and wanting to use some features of iCloud on my iMac I knew that I would need to make the move.

What was key for me was to ensure that the process was as smooth as possible. The first thing I did was back up all my data files. Though I back up on a regular basis, this process was to ensure that all my photographs, video files and documents were transferred to a backup hard drive. Once this was done, the next stage was to run Disk Utility to repair permissions, that went fine.

So the next stage was to start the Lion install process, and at that point disaster struck!

The install routine failed!

Install failed. Mac OS X could not be installed on your computer. Mac OS X Lion couldn’t be installed, because the disk Macintosh HD is damaged and can’t be repaired. Click restart to restart your computer and try installing again.

Yes, tried again same message.

Ah well, I thought, so I then decided to restart back in OS X Snow Leopard… but the OS X Lion installer wouldn’t let me.

Tried Disk Utility to repair the hard drive with no success.

At this point I was glad I had taken a backup of my data.

After looking at Apple Discussions, I tried to use my Snow Leopard install DVD to fix the drive, however this didn’t work. After a couple of hours of trying to repair the drive using various solutions, I decided that I wasn’t going to be successful trying to do that. So made the plunge and decided to format the drive and reinstall.

However… that didn’t work! I kept getting errors with the OS X install routine failing to install on the drive. In the end I just gave up and using the iPad booked a slot at the Genuis Bar at my local Apple Store.

Taking the iMac to the store went very smoothly, they connected it up to their diagnostic software, confirmed that everything was working as it should, except the hard drive.

As I had taken out Applecare on the iMac, the cost of the replacement hard drive and fixing it would be covered, however it would take between 5-7 days!

Hopefully it will all be sorted by then.

My thoughts – Apple announce OS X Mountain Lion 10.8

It was only in July last year that OS X Lion was released, today Apple announced a sneak peek at OS X Mountain Lion, 10.8 the next release of OS X.

The first thing that strikes you is the iOSification of OS X. In Mountain Lion you will find Messages, Reminders, Notes, Notifications, Share Sheets, Twitter integration, Game Centre and AirPlay Mirroring. Looking at the new features you may have mistaken that you were looking at iOS rather than OS X. The Sneak Peek page does say “Inspired by iPad. Re-imagined for Mac.

I do think some of the features in OS X Mountain Lion are much needed if you have and reply on an iOS infrastructure. If your friends and colleagues have iPads and iPhones and you have a Mac, you will have wanted some iOS features on your Mac. With Mountain Lion it looks like we’ll be getting them.

Mountain Lion is all about communication and sharing, it’s about connecting with friends and colleagues and sharing images and content. It’s about making the Mac more like the iPad and the iPhone and merging the experience. The back end means you can still run regular apps you do now, but the essence of the operating system will be familar to those people currently using the iPad.

If you think about it, that does make sense for Apple. Most people using the iPhone are Windows users, the same can be said for most iPad users. In order for them to move to the Mac, they are going to want to have a similar experience and feel moving from iOS to OS X. I know many people who are very happy with the iPhone and the iPad, but either don’t feel comfortable with OS X or are wary of moving to what they view as an alien and very different operating system. You can imagine how these iPhone and iPad users would feel if the Mac they saw in the Apple Store looked and worked like the iOS device in their hand.

This is emphasised in the sneak peek video which emphasises how similar OS X Mountain Lion experiences are to the experiences on the iPhone and the iPad.

From a marketing perspective if you want to convert iPad and iPhone users to Mac then making OS X to be similar to iOS is the way to do it.

So what about these new features for Mountain Lion?

Even though there are other messaging tools out there, such as Skype, the fact that Messages will allow communication with iOS devices has to be a plus, as it is built into the mobile operating system. The problem with Skype is that it requires you to open the Skype app and as that can “drain battery” I guess most people don’t have Skype on as a default and I suspect that the same can be said for other messaging apps. Messages on iOS integrates well with SMS so if you are use to SMS you will feel right at home with Messages. I also like the idea of sending images and video straight from my Mac, I can see it replacing e-mail for a lot of communication.

One of the reasons I’ve not used Reminders on the iPad or the iPhone was the lack of integration with OS X, so I am pleased to see that there may be a simple, yet useful, to do list app that works across all my devices.
For similar reasons I don’t use Notes on the iPad or iPhone either. Somehow I don’t think I will swap, as Evernote has much more flexibility than the Notes app, I like how I can add audio and image notes. For many people though the Notes app will be just what they needed.

I do like the idea of Share Sheets, it is one feature of using iOS that I repeatedly miss in OS X and falling back on copy and paste isn’t that bad I know, but once you get use to that “share” button in iOS you do miss it in OS X. In case you don’t know what Share Sheets means, it’s a simple button that allows you to quickly share links, content, images and stuff to places like Twitter, e-mail or Messages.

What the sneak peek does show is how Apple are betting on Twitter over Facebook. You see Twitter integration mentioned all over the place, but not a mention of Facebook. That issue with Ping and Facebook must still be a real issue!

I use AirPlay a fair bit from my iPad, earlier I wrote about how useful I found it with my Apple TV.

Adding this feature to OS X Mountain Lion will certainly be useful to me, especially with web based video that isn’t available on the iPad. Of course there is an assumption that Flash will be available for OS X Mountain Lion and that isn’t a given. I can quite easily imagine Adobe deciding not to make a version of Flash for Mountain Lion.

My over riding impression of Mountain Lion, combined with my experiences of using Lion on a MacBook is that we are seeing the end of the mouse more than anything. The use of the laptop trackpad and the Magic Trackpad in the Mountain Lion video demonstrates that Apple see the future of the human interaction with a Mac through gestures and a trackpad and not a mouse.

We of course haven’t seen any sign in the sneak peek of Siri for Mountain Lion, and I guess that either may arrive later or this is something that isn’t going to happen and I can’t see that happening; much more likely it will appear in the final release in the summer.

So will you be upgrading? My iMac is still running Snow Leopard due to legacy apps, somehow I don’t see me changing my OS just yet… on the laptop, more than likely as it already has Lion.

Overall what we are going to get with Mountain Lion is an iOSification of the Mac operating system, the upgrade is much more about new apps and a few subtle changes, rather than fundamental changes to the operating system.
