What should I do?

I started thinking about what I should do with my iMac now that it wouldn’t start and I couldn’t reinstall OS X onto it.

I knew I could copy files off it, so thought about whether I should start that. However that would mean using multiple drives and using another Mac. I knew that this would take time, as moving files from one mobile drive (well the iMac in disk mode) to another takes much longer than moving them from the internal HDD to an external HDD. The Mac mini I was using to connect to the iMac only had a small SDD so wasn’t an option.

In the end I decided that I would buy a new external hard drive.

I went with the LaCie STHG4000400 External Hard Disk Drive. I went with the 4TB version in silver.

Though I went with the USB-C interface, I knew that included was a UBS-C to USB 3.0 cable I could use with the iMac.

Having ordered that with next day delivery I turned the iMac off and left it alone.

Failure to install

Yesterday I tried to reinstall Mac OS X on my iMac which had failed to start. As I was ill I actually didn’t get back to the computer until this morning.

Alas the install process was still on the progress bar, which I knew wasn’t quite right.

Well I tried again to reinstall Mac OS X on the iMac which failed again.

I then put the iMac into disk mode and using another Mac viewed the drive, and I could see the files and documents.

I actually wasn’t too concerned about loss of data, as most of my working files are in the cloud in Dropbox and OneDrive, whilst all my images are currently backed up to Amazon Drive, as well as physical storage.

I suspected there might be a few files that I only had a single copy of, so decided not to reformat the drive and install a fresh copy of OS X.

Still feeling ill, I turned it off and went back to bed to watch Netflix.

Mac Fusion Drive failed again…

Well it had to happen didn’t it with my luck with the hard drive on my iMac.

The computer had slept the night before and I had woken up not very well so didn’t go to the computer in the morning. Though I was off work sick, I did need to start a Zoom meeting for an external consultant, but when I went to the computer pressing the space bar didn’t wake the computer.

I pressed the power button, counted to ten and pressed the power button again.

In the meantime I started Zoom on the iPad so I could do that before focusing on the iMac.

I was slightly annoyed that the iMac was now stuck on the Apple logo and progress bar.

Hmmm

Quick Google search, said to start in safe mode and identify the issue.

So turned the iMac off and attempted to restart it in Safe Mode.

Well that didn’t work.

So then tried Recovery Mode to repair the disk using Disk Utility. This did launch successfully, which was slightly reassuring that maybe it wasn’t a physical problem with the disk, but a software issue with the disk.

I ran Disk Utility, that indicated a few errors, so decided to reinstall Mac OS on the drive. I started this and left it to it.

Okay, let’s test the speed…

I’ve had my FTTP connection for over a month now, and I am chuffed with the reliability as well as the speed.

However though some of my devices directly connected to the router by cable can benefit from the 1Gb speed, most of the devices in my house are constrained by the speed of the wifi.

I did buy a TP-Link Archer T3U AC1300 mini wireless adapter for my iMac which is too far away to be cabled to the router.

This though was no faster than the built in Airport card, however I could use it on my MacBook which had a slower card and I have managed to achieve speeds in excess of 400Mbps, but not quite the 800Mbps I was hoping for.

My MacBook does not have an ethernet port so I have been unable to test a wired speed for the fibre connection. I bought an USB Network Adapter Syncwire USB 3.0 to RJ45 Gigabit Ethernet.

I did look for a Thunderbolt 2 to Ethernet adapter which I had used before with my MacBook but they were a lot more expensive.

It was plug and play (which I like and wasn’t the case with the TP-Link adapter) and connected my MacBook to the router via cable and tested the speed.

I was very impressed to get in excess of 800Mb/s via the wired connection.

I never thought I would see the day when my home internet access was constrained by the speed of my wireless network, how things change.

Tech Stuff: Top Ten Blog Posts of 2017

Over the last twelve months I have published 26 posts, many of these were about my return to fibre. So it is nice to see that the tenth most popular post on the blog this year was from nearly a year ago. We will have fibre in “12 months”! I said back then that according to BT Openreach we would have fibre within twelve months, I was slightly sceptical, but nine months after publishing that post I did get fibre.

The ninth post was about when my iMac Fusion Drive Failed and had to have it replaced.

The post at number eight was another post about my fibre journey, Still checking… was when the cabinet was activated, but alas wasn’t accepting orders.

The post at six was about Dusting off the Pogo my old Polaroid Bluetooth pocket printer. Still going strong.

The fifth post was how I don’t like BT FON which was originally published in 2011.

The post at number four was wondering Where are my Comic Life Styles? I found them.

The third most popular post was about the free wifi (or lack of) on my holiday, Haven no wifi

The post at number two was Comic Book Fonts which was about the amazing comic book fonts from Comic Book Fonts.

Not updating yet…

high sierra

So Apple have released their latest operating system, well actually they did it a few weeks ago.

I still have yet to update my iMac (and my MacBook) to the new operating system. The main reason is not that I really like Sierra and don’t want the new features of High Sierra. Nor is it because I have really slow internet and it would take days to download the update, on the contracts, now I have fibre, my download speeds are respectable and it now takes minutes rather than hours or days to download large updates, such an operating system upgrade. It’s just that I have had my fingers burnt before when applications I use on a regular basis suddenly stop working on the new operating system.

The main culprit for my is usually Adobe’s Creative Cloud, however I am hoping now that they have moved to a subscription model that my regular Apps will be updated automatically and quickly. I also heard people were having problems with Microsoft Office, but I have also heard that Microsoft have released updates for these programs as well.

Sometimes it is the smaller software houses and struggle, but part of the issue is me! If a piece of software is working for me, and there is an application upgrade, I really need to justify paying for the upgrade.

So the following packages stopped working for me in the past following operating system upgrades, Screenflow and Parallels. So if I upgrade the operating system, which is free, I then need to spend real money upgrading certain applications. I am expecting Comic Life 2 to stop working with this upgrade, so then needing to upgrade to Comic Life 3.

So having waited a few weeks I think I may do the upgrade soon.

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.

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.

Slow, but sure

iMac

I am finally getting my iMac working again after the system crash. Though I do have backups, there was some recent data that I wanted to retrieve, and as I do manual backups of the data (I know)my preference was to restore the drive as is, rather than rebuild from scratch. The simple way would have been format and then resinstall my apps and data.

Initially I was able to get the drive to “appear” using Firewire Target Disk Mode using another Mac. So my first approach was to “fix” the drive using the OS X Drive Utiity. This failed and the error message wasn’t that helpful, which was format and reinstall! I could mount the drive and read the files on the iMac, but couldn’t write to the drive or delete files.

My second approach was then to clone the drive onto an external Firewire drive, however this just didn’t work, in the main as I have a large full 1TB hard drive. So I went with manually copying over the files, but as I was copying from Firewire to Firewire through an old Mac, this was slow. When Finder said it was going to take 720 days (yes days not hours) to coop over 200GB of data, I knew that this approach wasn’t going to work.

So I created a boot drive using a spare external Firewire drive and installed OS X onto that. I then booted the iMac using the external Firewire drive as the startup drive. Success, however, though when using another Mac I could see the internal drive, when booting the iMac from an external drive the OS wouldn’t let me mount or see the internal drive.

Using the Google I searched on the Disk Utility Error Messages and the response across the web was to use DiskWarrior. I was a little hesitant as I suspected now that the drive problem wasn’t file system or OS based, but was a hardware problem (based on my previous experience).

In the end I did decide to buy DiskWarrior and once installed I got it going to let it do its work.

It took a fair few minutes to get going, but alas it couldn’t fix the directory problems and confirmed that there was a hardware issue with the drive and it would need to be replaced. However it also created a temporary file structure, which allowed me to copy files off the drive onto the replacement external hard drive and importantly do this quite quickly.

I was unable to clone the drive, but as I could copy files I was able to confirm I had the most recent copies, as well as checking system files.

So at the moment I am using an external drive, I will be taking the iMac to the Apple Store as I am disappointed that the replacement drive didn’t last very long, even though I am out of AppleCare.

It’s crashed, it’s crashed…

Well maybe I should have been expecting it to do that, but my four year old iMac last night decided to throw a wobbly and fail to restart after crashing out.

Despite some attempts to start in safe mode, reset the PRAM, in the end I started it off in Firewire Target Disk Mode and connected it to another Mac. The result it looks like the hard drive is on the edge of failure. This is annoying as this was only recently replaced under AppleCare. My iMac is now out of AppleCare, so I am not sure what to do. The SuperDrive has also stopped working properly, well maybe it stopped working ages ago, I rarely use it, so perhaps I didn’t notice.

I am not sure what to do next, I do want to still use the iMac, but should I repair the drive or look to replace it. I would like to probably upgrade it to an SDD and then replace the SuperDrive with a standard HDD, but not sure if there is someone who can do that for me, or how easy it is to do myself.
