Re: Imager says "error writing to storage (while flushing)"

v1.2 no longer reports flush errors (on Windows), so should work better for those affected.

Re: Berryboot crazy slow download

NOOBS and PINN give you a supported multi-boot. Berryboot fails the KISS principle. Would still argue it's the only option, if you want to be able to add & remove OSes later... To answer the TS's question. Berryboot downloads the OS images from sourceforge. If the sourceforge mirror it is using doe...

Re: "Introducing Raspberry Pi Imager, our new imaging utility"

That's interesting. Would it be feasible to check the files in a multifile zip to see if any of them is an image file, and image that instead? How do you make out an image file? .zip files that do should be extracted to card tend to contain files that end in .img as well. Think of the noobs .zip th...

Also, RaspberryPi Imager was very happy to let me burn the .zip archive of the .img file rather than burning the .img file itself.

Re: Why is NOOBs suggested to be used by Raspberry beginners?

I'm curious what happens if you lose network connectivity mid-write. It supports download resumption and retries automatically if connection to webserver is lost. (As long as it did manage to download at least a little bit in the first place, you keep the app open, and do not shutdown the computer).

Re: Unzipping in a pipeline

The central, core problem with the ZIP file format is that the directory information is at the end of the file. Therefore, you have to read the whole file before you can tell what is in the file (sort of like the ACA [inside joke...]...) This makes the whole thing impossible. Pipelining .zip files ...

Re: What is a good replacement for Etcher (ads and ignores privacy)

Does that mean the optimal write block size is 4M ? If you are using unbuffered IO (e.g. oflag=direct with dd) probably, yes. If not, keep in mind that the kernel will buffer your writes, so will likely already write much larger chunks to storage than the block size you specified in your program. S...

This is all very interesting.
I used blockdev to get the info for the Pi's SD card (64GB Sandisk A1 class)
For writes it may be more interesting to see if your card reports the erase block size, e.g.:

Code: Select all

I have had bs=4M fail in the past whereas bs=1M worked fine.
The image file size probably wasn't dividable by 4 MB then.
dd doesn't like partial blocks.

I think people are upset about the fact that it (apparently) requires a network connection to run - and can be seen to be doing network communication while running (if you use something like Wireshark or tcpdump on it).
