Hello, I’ve been trying to flash something and it gets to 7-8% in verification and then I get a flash failed. I’m using windows 10 and etcher 1.5.116. I’ve tried turning off anti virus software, and reinstalling software. I’m using a brand new microsd card as well as a new microsd card reader. I only have one port on my computer so at the moment I cannot try another. I have a copy of the error I was given from the developer tools. ```auto gui.js:31760 Verifying 1 device, 2% at 74.60 MB/s (total 74.60 MB/s) eta in 48s with 0 failed devices gui.js:31760 Verifying 1 device, 5% at 84.20 MB/s (total 84.20 MB/s) eta in 42s with 0 failed devices gui.js:31760 Verifying 1 device, 7% at 86.80 MB/s (total 86.80 MB/s) eta in 39s with 0 failed devices gui.js:42737 {"message":"read ECONNRESET","stack":"Error: read ECONNRESET\n at TLSWrap.onStreamRead (internal/stream_base_commons.js:200:27)","config":{"url":"https://balena.io/etcher/static/config.json","method":"get","headers":{"Accept":"application/json, text/plain, */*","User-Agent":"axios/1.5.116"},"transformRequest":[null],"transformResponse":[null],"timeout":0,"responseType":"json","xsrfCookieName":"XSRF-TOKEN","xsrfHeaderName":"X-XSRF-TOKEN","maxContentLength":-1,"maxBodyLength":-1},"code":"ECONNRESET"} gui.js:42737 Tue Feb 16 2021 21:45:02 GMT-0800 () Validation error ({"image":{"size":4215275520,"compressedSize":1059754885,"hasMBR":true,"path":"C:\\Users\\von\\Downloads\\","partitions":[{"offset":4194304,"size":268435456,"type":12,"index":1},{"offset":272629760,"size":3942645760,"type":131,"index":2}],"isCompressed":true,"name":"umbrel-os-v0.3.2.img","extension":"zip"},"drives":[{"size":32010928128,"isVirtual":false,"enumerator":"USBSTOR","logicalBlockSize":512,"raw":"\\\\.\\PhysicalDrive1","error":null,"isReadOnly":false,"displayName":"D:\\","blockSize":512,"isSCSI":false,"isRemovable":true,"device":"\\\\.\\PhysicalDrive1","busVersion":"2.0","isSystem":false,"busType":"USB","isCard":false,"isUSB":true,"devicePath":null,"mountpoints":[{"path":"D:\\"}],"description":"SanDisk SDDR-B531 USB Device","isUAS":false,"partitionTableType":"mbr"}],"driveCount":1,"uuid":"3f387d35-2cb3-4745-bbb8-030030914b22","flashInstanceUuid":"3f387d35-2cb3-4745-bbb8-030030914b22","sample":0.1,"applicationSessionUuid":"d529ea7c-348e-4e40-97b6-ee74ebb9dff5","flashingWorkflowUuid":"cbf3e67f-6e88-4e08-a2a7-b7d57988f593"}) gui.js:31760 Verifying 1 device, 8% at 86.90 MB/s (total 86.90 MB/s) eta in 39s with 0 failed devices gui.js:42737 Finish: 316669952 gui.js:42737 Terminating IPC server gui.js:42737 Flash results 1. {results: {…}, cancelled: false, skip: false} gui.js:42737 Tue Feb 16 2021 21:45:07 GMT-0800 () Done ({"image":{"size":4215275520,"compressedSize":1059754885,"hasMBR":true,"path":"C:\\Users\\von\\Downloads\\","partitions":[{"offset":4194304,"size":268435456,"type":12,"index":1},{"offset":272629760,"size":3942645760,"type":131,"index":2}],"isCompressed":true,"name":"umbrel-os-v0.3.2.img","extension":"zip"},"drives":[{"size":32010928128,"isVirtual":false,"enumerator":"USBSTOR","logicalBlockSize":512,"raw":"\\\\.\\PhysicalDrive1","error":null,"isReadOnly":false,"displayName":"D:\\","blockSize":512,"isSCSI":false,"isRemovable":true,"device":"\\\\.\\PhysicalDrive1","busVersion":"2.0","isSystem":false,"busType":"USB","isCard":false,"isUSB":true,"devicePath":null,"mountpoints":[{"path":"D:\\"}],"description":"SanDisk SDDR-B531 USB Device","isUAS":false,"partitionTableType":"mbr"}],"driveCount":1,"uuid":"3f387d35-2cb3-4745-bbb8-030030914b22","status":"finished","flashInstanceUuid":"3f387d35-2cb3-4745-bbb8-030030914b22","errors":[{"name":"Error","description":"SanDisk SDDR-B531 USB Device","code":"EVALIDATION","device":"\\\\.\\PhysicalDrive1"}],"devices":{"failed":1,"successful":0},"bytesWritten":316669952,"sourceMetadata":{"size":4215275520,"name":"decompressed-image-22ba04edfb57.tmp","blocks":[{"blocks":[{"offset":0,"length":334495744}]},{"blocks":[{"offset":406847488,"length":512753664}]},{"blocks":[{"offset":922746880,"length":489684992}]},{"blocks":[{"offset":1413480448,"length":347078656}]},{"blocks":[{"offset":1764753408,"length":1048576}]},{"blocks":[{"offset":1854930944,"length":3145728}]},{"blocks":[{"offset":1859125248,"length":775946240}]},{"blocks":[{"offset":2636120064,"length":19922944}]},{"blocks":[{"offset":2657091584,"length":9437184}]},{"blocks":[{"offset":2667577344,"length":22020096}]},{"blocks":[{"offset":2690646016,"length":1101004800}]},{"blocks":[{"offset":3795845120,"length":63963136}]},{"blocks":[{"offset":3896508416,"length":1048576}]}],"blockmappedSize":3681550336},"sample":0.1,"applicationSessionUuid":"d529ea7c-348e-4e40-97b6-ee74ebb9dff5","flashingWorkflowUuid":"cbf3e67f-6e88-4e08-a2a7-b7d57988f593"})  ``` ​ ---

Hi That’s strange, and thanks for sharing the logs. - Can you try something - disable write verification from the settings, and see if your device actually works as expected. Let us know how that goes. - Can you share what image you are using? Some images, for example Tails OS have known issues. - Also take a look at the answer from my colleague [here](https://forums.balena.io/t/checksums-do-not-match/36537/82) ---

You are right. Seems like that feature has been removed from the recent versions of Etcher. I was looking at an older release. Let me get back to you after talking to the engineers working on Etcher ---

I tried it on a different computer and had the same issue at 8%. Going to purchase new microsd and reader and hope the problem is something do with that even despite the previous ones being brand new. ---

Hi Did the different computer have the same OS as this one? If yes can you try this from Linux or Mac? ---

Hello, This is either the same issue as [Checksums do not match - #82 by zvin](https://forums.balena.io/t/checksums-do-not-match/36537/82) or a faulty SD card. Try flashing the same image to the same SD card from a Linux or macOS computer to be sure. The `Validate write on success` setting was removed recently. Etcher will always verify after writing, you can hit the `skip` button to skip the verification. ---

I had to use a micro SD to SD adapter for it to work. Not sure why that was a problem but it was successful after that. Thank you all for the suggestions ---

Hi, glad to hear this worked. Did you tested other mSD cards without the adapter to see if you get the same issue? ---

Yes I tried it on two different computers with the microsd and I also used two different readers. It wasn’t until I used the micro to sd adapter that it worked.
