A sandisk extreme UHS-1 U3 32gb card.
I did do a factory reset but I never really noticed a speed improvement.

Benchmarked both the cards with crystal disk mark but I've lost the logs.
From what I remember 4k performace was 2 or 3 times faster.

Was yours slow from factory?? Is the card brand new?? Mine seemed pretty good but I only just flicked through the pages of a book before I put in the new card and started using koreader.

I format the sd of my kobo glo hd

Hello,
I hope you could help me. I had been having problems with my Kobo glo hd, at the beginning this got blocked principally when I highlighted some long paragraphs. In order to solve it I did several factory resets and try some old firmware but after this the Kobo got blocked much more frequently until that it was impossible to use it (at the end when I was reading, got blocked and then said that I should connect to Kobo desktop for setting up, and this happend again and again).
I was thinking that it could be a problem with the battery or the sd and I format the sd because I thought that I could install a new firmware (terrible mistake, because I have not read this post yet). I have some doubts now:
- If I get and image for my 4gb sd´s Kobo I could solved my mistake? Where I could get it?
- Is it possible discard that it is a battery problem without buying a new one?
Thank you for your time.

Sorry, I can't tell from the description what went wrong. I don't know what you mean by "blocked principally when I highlighted some long paragraphs". But, if the SD card was failing, you can get issues such as slow performance when something, such as a highlight, needs to be saved. Replacing the SD card would fix that.

I don't think a failing battery would have this affect. That would simply reduce the runtime and mean you need to charge it more frequently.

I have sent you a PM with the link to the image. It is for the 2GB 4GB card, but you can use it on a larger card and expand the book partition. Any size should work. 16GB will definitely work. There were reports that 32GB worked, but, also reports of problems with it.

You will need to do the setup using the Kobo desktop application, or by manually installing newer firmware. This is because Kobo now requires at least TLS1.2 for connections, but the factory firmware in the image does not support this. If you manually install firmware, it needs to be at least 3.19.x.

Edit:
Sent another PM with the correct image.

I use a Samsung 64GB microSD on my Glo HD. Works pretty well. Some microSD cards have poor random 4K (even Class 10 or UHS).

I didn't read that post properly and missed that it was a Glo HD instead of a Glo. I have updated the SD card in my Glo HD. I can't remember if it was a 32GB or 64GB. The selection was based on cheapest card available on the day, rather than size.

I'm trying to run this procedure using a Kingston 8GB SD card and an image for the Glo HD I got from Davidfor in the image thread.

The SD card was from a RPi. The writer process failed after a while the first time I tried it, seemed to have created the partions though.

I then tried a second time and that failed as well so i removed all the partitions using minitool and tried again, also failed but crashed out. I formatted the drive using SD formatter to FAT 32 and it now crashes out and disappears every time I try to use the USB Duplicator Writer.

I made an image of the card first using the Image Creator so I tried to restore that...also crashes out and disappears.

Am I doing something silly?

Maybe I need to partition it up first?


EDIT: I used Windows Disk Management to delete the volume and created a single 10MB FAT16 partition, for whatever reason this has resolved the problem and it has written the image successfully.

Thumbs up

I've replaced the microSD card in my Kobo Glo HD. It works fine. I use SAMSUNG EVO Plus microSDXC UHS-1(U3) Class10 64GB. But I left 512MB for linux swap space as a logical partition.

The OS hasn't been configured to use an swap space. So, that is going to be unused. There is probably a way to change that, and someone with better Linux skills might come along and tell us how to do so (in a separate thread).
