Running out of Rpi install options

[cbweb]

Hello,

Installing an OS on my Raspberry Pi is becoming an ordeal.

Tried with an SD card 7.5gb in size and ran into SD formatting issues. I resolved these using Disc Manager in windows 10 administrative tools to create a single healthy formatted partition also using sd card formatter but install of Raspian went awol with frequent screen freezes and intermittent blanking of monitor screen ultimately a failed install.

I moved to a 16gb SD Card and formatted per instructions creating a single healthy partition on that card.

Using new version of Noobs the install appeared to go fine until the last few % then screen went blank and install failed.

Next I used ETCHER and once again prepared the SD Card formatting it and Etcher flashed the image of Raspian I used and it seemed to go fine. Then it verified its install and gave the following message ""The write has been completed successfully but Etcher detected potential corruption issues when treading the image back from the drive."

I guess I'm out of options at the moment.

Cheers,

Colm

If you only want to install Raspbian, which you do, do not use NOOBS. As far as I can tell it creates more issues than it solves. Judging by the questions that come up here frequently.

Follow the installation instructions here:
https://www.raspberrypi.org/downloads/raspbian/

Or as you have found, Etcher is an easy way to go. And it verifies your new SD card image.

There is no need to do any formatting of an SD card prior to burning a Raspbian image onto it. The image writing will overwrite any formatting you have done anyway.

As Etcher says that verification has failed for you it is almost certain that your SD card is dead.

Get a new SD card and try again.

Be sure it is big enough.

I would also check your card reader supports SD HC cards some building ones on PC's don't.

I had similar problems with my old card reader. Then I used a friends laptop and Etcher created a perfect image on the same SD card.

I ordered hundreds of electronic parts, motors, cameras, ... from aliexpress and all are good. Besides the 4 16GB SD cards I ordered, all 4 are bad. Even writing Raspberry image with different computers did not help, and once when the checksum after writing was what it should be, after initial boot and resizing of Raspberry filesystem bad things happened again.
Summary: I will not order SD cards from aliexpress, just go to local drugstore and buy there, a little bit more expensive, but none of the 8/16GB class10 cards bought there ever failed!

I have occasionally gotten a bad verify from Etcher, usually a retry is successful. Pretty sure it has something to do with recent versions of Windows 10 or Etcher, because I didn't used to have that problem, and my equipment hasn't changed (other than Win10 & Etcher updates).

Verify the SHA256 hash sums of your download to ensure you aren't starting with a corrupt image.

Note you don't need to pre-format the SD card or even extract the image from the zip archive when using Etcher. Etcher can write the image directly from the archive, and the filesystem in the image will overwrite anything previously on the SD card.

Thanks for replies and heads up on not needing to continually format the card for Etcher to work.

I've made some progress and I'll test later today. I belong to a ham radio club ( I'm trying to get a TNC-PI module working) and one of the guys suggested the power supply can be an issue. I was using an Android phone charger that runs on mains but suggestion was it doesn't give enough power. Powering the usb connector from laptop directly seems to have improved things but we didn't get a full install going as yet though testing alternative monitor. Also was using a French style keyboard we discovered some keys not responding so later I'll switch that out as well. Also I saw the following in another thread which might eliminate the monitor issue if there is one. I should also say the sd card is a good 16gb Kingston card so that should be ok. At least there are no memory corruption issues being alerted.

The best way to get display devices working is usually to remove all the HDMI and framebuffer stuff from /boot/config.txt and let the RPi and HDMI negotiate the display mode that they can use. "

I'll try the above later.

If, however that "auto-negotiation" doesn't work too well, but you are able to login to the Pi remotely (or other method of command-line access/partial, but readable display etc.), FWIW, you may find these notes on the use of the tvservice command of interest:

Overwriting it detected potential corruption issues in verifying the write

Using GUIFORMAT FAT32 Format only loaded the 43M boot sector of the sd card.

in administrative tools/computer management/disk management I deleted the partitions on the disk, then created a new simple volume with a quickformat fat32 option in windows 10.


In win 10 disk management the sd card now cant be seen. I remove and reinsert it and it appears as F: drive.
with a boot sector created of 42MB, Primary partition of 1.68GB and 13.11 GB Unallocated.

SD card returned to Raspberry PI.

in Etcher chose the 2017-08-16-raspbian-stretch-lite img file

This time Flash completed without any validation errors



Connecting new keyboard, mouse, hdmi cable, and note above power supply cable with its android type power supply jack to usb connection on laptop I see red led on Raspberry Pi and green led showing somethings loading. Switching on monitor I see everything has loaded to username and pwd. I enter pi and raspberry and get to a Debian GNU/Linux waiting next command.


So all is good. All I gotta do is figure out next steps from there. Thanks all who helped. Note I've not yet had to use the code above to help raspberry pi negotiate monitor on hdmi.
