[Solved] iso corrupt from download

silvervein

@rbaker and @mitu – Thank you for your replies!

@mitu to answer your question about the corrupt ISO, I download the file extract it and when I double click on it I get an error that it’s corrupt. I’ve been able to double click on other ISOs and they open in Power2Go a Cyberlink ISO Viewer I have. (Reference screenshot) note the Retropie icon/description are different from the Ubuntu icon/description.

I’ve re-downloaded the image from the link @rbaker provided but when I go to flash it over with Etcher, the program just sits at “Starting” after I’ve selected the image and the SD card and it does nothing.

I’m trying to use a SanDisk Ultra 64GB (10) that has been partitioned in half so I could format it in fat32. It wasn’t until after I got the 64GB micro sd card that I found you should really use a 32GB or smaller due to fat32 vs exfat format limitation. I do have a 16GB card ordered and am waiting on delivery. But for now it seems (unless I’m misunderstanding something) that my image is corrupted.

Please clarify if I’m making a mistake.

Thank you again for your responses, much appreciated!

@silvervein The image from the RetroPie site is not an ISO file, so Power2Go would not be able to 'open' it. It's not corrupt, you're just using the wrong tool for the job.
As for the 2nd part: you can use a 64Gb SD card without any problems with RetroPie, but it will overwrite the card's contents anyway, so there's no need to partition it. RetroPie (or rather Raspbian Linux) does not use exFAT for it's main content, so there's no limitation here either.

Why are you doing this? Just follow the guide in order. You format a card with SD formatter followed by writing the image using either option.

@silvervein Your over-thinking this. Just download the file from the retropie site, start etcher, select the file WITHOUT extracting it (leave it as a .gz file), insert the SD card into your computer so etcher can find it, click on flash and it will install retropie on the SD card. Insert it into your Pi and power it up. It will then boot and if a controller is plugged in it should detect it and ask you to configure it.

Installed Etcher (v1.2.0), deleted my original download and started over following instructions from @glennlake.

Round 1:
Opened Etcher, selected zip (.gz) image, selected my SD card. Once I clicked on "flash" I'm asked for my admin password (entered it) then it locks up and the flash button now says "starting".

Round 2:
Logged in as admin, followed the previously mentioned steps. It flashes over but then crashes when "validating". see screenshot

SD card is brand new and I've copied files to it for testing purposes (no issues).

@silvervein OK, I just did a search in the forums and I think your problem is with the SDXC card and 'etcher'. There are several posts saying people are having problems with that type of card (I am using a 128GB SDXC card without problems). I don't think etcher is compatible with this type of card. I remember you have access to a linux machine. I use dd to flash an image to an SD card with no problems. If your not familiar with dd command there is a GUI program called 'dd Utility' that will make it much easier to use. You can do a google search for the webpage explaining how to use it.

@silvervein I did a little experimenting and I was able to format and install RertoPie on a 128 SDXC card using Etcher. I wasn't able to format the card on my Win7 machine (no win10 here) in ether NTFS or exFat so I formatted the card as Ext4 on my linux machine. I was then able to format the card as exFat on my Win7 machine. I started Etcher and was able to flash the latest RetroPie to it and it booted OK. I hope this helps!

Sorry I have not responded sooner, life and all that.

TLDR: I have the image working on my Raspberry Pi now! Thanks @glennlake

I did just recently get a laptop running with Linux (Ubuntu 16.04) on it. I downloaded the dd-Utility (v1.5 beta) and tried to flash the image that way. I select “restore” based off the criteria and after about a minute, I get “Volume Restore Complete”. When I go to boot the image off my pi nothing happens. Checking the sd card shows no files on it.

I tried it with the flash card being formatted as NTFS, then again with ext4. The above mentioned issue was with NTFS. On ext4, I get an error that no memory card is found.
(note: I’ve tried this on two separate sd cards, both using the extracted .img file and the .gz file)

So then I downloaded Etcher for Linux and tried that, it worked. Still frustrated I couldn’t
get it to work from Windows 10 but now I can get games for my kid.

Thanks again to everyone who has provided inputs!

glennlake

@silvervein Thanks for keeping me updated. So glad you were able to get you Pi setup for your kid. I've found that the larger SD cards (SDCX) can be stubborn with how they are setup. I use linux on my main machine so working with RetroPie is a bit easier for me.

hey guys, I have the same problem. Can someone confirm that the cuurent image for pi 4 is downloading correctly? cheers
