OSStatus error -1073741275

I have now connected an external hard disk to my Synology NAS. Trying to use my external HDD for time machine backups did not work.

The problem was that I only set up the time machine user permission in Control Panel / External Devices.

This will cause an OSStatus error -1073741275.

The permissions also need to be set up in Control Panel / Shared Folder / [Name of Share] / Edit / Permissions for the time machine user.

WD Red – coincidence?

I have six 3TB WD Red HDDs. All made in Thailand except one that was made in Malaysia. Guess which one just broke while the others are still fine.


Yes, the sample size is quite small, but just like I used to have more problems with Seagates than with WDs (until I stopped buying Seagates) I wonder whether there is another distinction to be made – between different WDs.

German Apple Keyboard and Windows 10

My employer reinstalled ‘my’ Surface Pro as part of an update. As I also work from home I wasn’t able to use it with the keyboard on my desk anymore: a German Apple keyboard. This blog post will be in German as it will be of limited use to a English speaking audience.

Deutsche Apple Tastatur unter Windows 10, genau das umgekehrte Problem von diesem Blogeintrag. Als ich meine Apple Tastatur unter Windows 10 benutzen wollten waren alle nicht alphanumerischen Tasten ‘falsch’ belegt und ich wusste nicht mehr wie ich das Problem beim letzten Mal gelöst habe.

Hier meine Gedächtnishilfe und vielleicht auch Hilfe für den ein oder anderen Leser meines Blogs.


1 Apple Computer

1 USB Stick


USB Stick in den Apple Computer, dann den Boot Camp Assistant (in Utilities) starten. Passende Optionen auswählen.


Nun werden die neuesten Treiber auf den USB Stick geladen.

In Windows dann folgende Treiber installieren


Die meisten Sonderzeichen, aber nicht alle, sind nun richtig belegt.

Nihao Tianmao

There are lots of smart speakers on the market. In China, the ones offered by TMall are quite popular and during a recent trip to Shanghai, our family got one as a gift from a relative. I had a look and at that time this model sold for RMB 89, approximately £10 / €11 / $12.


According to the box it supports Bluetooth and is dts ‘certified’. I am not sure whether that means that the speaker has to fulfil certain minimum requirements regarding sound quality or whether it just means that it can play certain sound formats.

The speaker itself is very small and, considering it’s small size and low price, it sounds great.


There are however a few drawbacks if you want to use this speaker, even if it’s only as a Bluetooth speaker.

  • It (currently) only understand Mandarin – no other Chinese dialects and no other languages.
  • You need to install the TMall app on your phone to install it, you then need a TMall account, too. They do want you to be bound to their eco-system.
  • You need to ask the speaker to pair with a Bluetooth device in Mandarin. There’s currently no button combination that lets you go into pairing mode.

I set up a guest network in my Wifi router. I wasn’t too keen on Tianmao (‘Sky Cat’) seeing my other network devices.


After updating my GR II’s firmware I noticed that the Auto-Hi ISO setting didn’t work anymore as expected. I try to keep the shutter speed at least at 1/60 sec – but after the update it went as low as 1/40 sec for some shots. The manual didn’t provide any explanation in the Auto-Hi section, but it turns out that after the update Dynamic Range Compensation was on Auto, which means that the Auto-Hi setting gets ignored and the Auto ISO setting gets used instead.

Dynamic Range Compensation
Dynamic Range Compensation (p.51)

This is in the manual, but not being mentioned under Auto-Hi. Normally you wouldn’t think of looking in the Dynamic Range Compensation if you have an issue with the Auto-Hi ISO setting, so I thought I spell out what is going on, somebody else might benefit from this information. I certainly have turned Dynamic Range Compensation off.

Rico GR II vs. Leica X1 – a subjective comparison

The Leica X1 came out in 2008. I bought a used one in 2012, when the second hand price became affordable and have loved this camera ever since. My main issue with the X1 is that the autofocus is very slow.

The size of the camera is great, which is the reason I often use it instead of my SLR.

Leica X1

Now in 2018 I still use the X1, but the main issues are worst under the circumstances I need the camera most: when taking photos indoors with small kids, e.g. at family gatherings.

A few days ago I bought a new Ricoh GR II in the hope it will fix some of the issues I have with the X1 (if it is better for my purposes I will sell the X1).

Leica X1


Both have APS-C sized sensors. Nice. Megapixel count is not much of an issue for me (12 vs 16 MP).

Low Light Performance

I expected much better low light performance with the GR II. When shooting raw and using Lightroom to me there’s not much of a difference between the GR II and the X1. Why Lightroom? I get Lightroom for free through my employer’s education licence and to me raw photos in Adobe’s Lightroom look much better than in Apple’s Photos. The GR II can go higher in terms of ISO, but I haven’t really done enough above ISO 3200 to have a valid opinion. If I didn’t have access to Lightroom I might have a different opinion. I guess the reason I don’t see much of a difference is because of all the clever stuff Lightroom does with the raw files.

Ricoh GR II


The GR II is easy to handle with one hand – taking it out of the ‘belt case’, turning it on, taking a photo. Turning it on is much faster and most importantly the autofocus is much faster. The screen of the GR II is also much better, nice, but I don’t care about it that much.

Some things are much easier to set on the X1, e.g. shutter speed, aperture, but for me the short time it takes from ‘camera in the case’ to ‘taking a photo’ is so much better with the GR II that it outweighs all other disadvantages the GR II has. I especially like the setting where I can determine at which shutter speed the ISO value should change. I currently have it set to 1/60s, but might go higher. I think trading high ISO noise for less motion blur might be worth it.

The level display (a kind of electronic spirit level) is a really nice feature. I don’t really use the one in my SLR, so didn’t expect to like or even think about the GR II’s level display but have come to really like it in the few days I used the GR II.

Lens and Choice of Camera

The GR II has a 28mm equivalent lens, whereas the X1 has a 35mm equivalent lens. I very much prefer 35mm, but there isn’t much available in that size. Cameras like the Fujifilm X100 are much bigger than the X1 / GR II, so are out of the race. The Sigma DP2 is similar in size to the X1, but as far as I can tell not better than the X1, at least not for my purposes. A used Leica’s X2 is unfortunately (still) too expensive for my budget. I could have gone for the X70, but explaining why I ended up with the GR II would distract from the point of this blog post.
