Writing to the memory card was not complete correctly.

“Writing-to-the-memory-card-was-not-completed-correctly” Endless Error Message Loop and How I Was Able To Resolve


Original Article by:  Keith Hamilton


Recently, I encountered a problem with my Sony A7RM2.  The camera was stuck in a error loop, “Writing to the memory card was not completed correctly,” and to my astonishment, the camera was quite unusable.

Any selection made would lead to this error loop, and it would keep repeating.  I tried everything I could think of.   I powered it off and on several times, tried inserting other SD Cards (SanDisk), and swapping out other genuine Sony batteries, but to no avail, the camera would not come out of this loop.

Also, I tried to force it in to Mass Storage mode by connecting my camera to my computer with a Micro SD cable, but, again, all to no avail.

Stuck in this error loop, there was no getting to the main Menu to reset.  And, apparently there is no hard reset on this camera, like a little recessed button that you can press with a paper clip or the tip of a ballpoint pen.

Nothing I tried would get the came out of this error loop and back to the menu.

One might imagine that I was thinking to myself,” Are you kidding me?”  What kind of Sony software error is this?    Frustrated, I pulled out my computer and searched the Internet, only to find a scarcity of articles on this specific error.  There was not much on this subject or this error, nor was there a viable solution.  Why has Sony not already corrected this software error?  


So like any other owner of photographic equipment that fails, I called the Sony Technical Support.  The technician kindly advised me to remove the battery and SD card with the camera turned off, turn on the camera with no battery or card, and then hold the shutter button for sixty seconds.  

He then advised to turn off the camera and reinsert the battery.  Once the battery was reinserted, he said to turn on the camera.  

When the camera was turn back on, unfortunately, the camera went right back to the error loop.   He calmly said you will need to send it in to have it serviced and he e-mailed me instructions on how send it in for service.  Gosh-darn it!

Determined to find a DIY solution, asked for help on a Facebook’s Sony User Group page, which I am a member.  I asked, “Has anyone had this issue? Does any one know what caused this issue? How can it be fixed? Thanks.”    Several users responded with suggestions and follow up questions, like “did you try this,” or “did you try that,?”  Even a member who is a Sony Tech Support made a few suggestion.  But alas, nothing works and the final decision was “send it in to Sony for service.”  Drats!

Like a college student on a mission to finish a term paper at the eleventh hour, I was determined to see this through to its conclusion.

I thought that perhaps the Micro USB cable is the issue.  Sony is funny about the cable used to update firmware, the manual recommends that one only use the Micro SD cable supplied with the camera.

I checked the Micro USB cable that I was using and it was not a Sony Cable.  I have three Sony mirrorless cameras, and I could not find one Sony cable.  I ordered a replacement cable from Amazon “Sony EC803 Detachable MicrosUSB Cable, Black for Sony,” and anxiously wait for the cable to arrive.

The cable arrived a few days later and it was time to fix this camera.  I connected the cable to the my MacBook and then to camera with the camera off, then powered the camera on, holding my breath as it cycled on.   The error loop again showed in the camera screen.   I felt like I was kicked in the chest.

Not quite ready to give up, I tried again, with a different twist.

This time, while depressing the shutter button, with one end of the Sony cable in the camera and the other connected to my computer, I again powered on the camera, and Viola! it finally went into Mass Storage mode.   Woohoo!

I proceed to reset the camera per the manual, now that I had access to the menu.

Finally, I still do not know what caused this problem, and I do not even if this is a definitive fix, but after reseting the camera, it seems to be still functioning properly.



What I Did to Reset Sony A7RM2 (What worked for me):

  1. Camera off.
  2. SD card removed.
  3. Battery in camera.
  4. Connect genuine Sony MicroUSB cable to camera and computer. (Searched Amazon)
  5. Depress shutter.
  6. Turn on camera.

This sequence forces the camera to go into Mass Storage Mode and interrupted the “Writing-to-the-memory-card-was-not-completed-correctly” loop.   The camera was disconnected and returned to photography mode.   Then, through the reset menu, I reset the camera to default settings.



What Sony Service Representative Advised:

  1. Turn off camera.
  2. Remove battery and SD card.
  3. Depress shutter button.
  4. Turn on camera with shutter button depressed for 60-seconds.
  5. Move button to off position, and release shutter.
  6. Replace battery.
  7. Turn on camera.

Unfortunately, this did not work, and he advised that I send in camera for repair.

I recommend reading through the comment, as others have resolved this camera-incapacitating error loop in different ways.   My sincerest thanks to those who responded.

  1. I fixed this by holding down the “menu” button in a brief moment before the camera got into its looping error-data-recovery screens; I eventually was able to get into the main menu, get the USB setting to “mass storage,” connect to a PC and load the latest firmware, which also did a hard reset. After that, the camera re-formatted a card, and now it works. Nothing else in the realm of contact cleaning, power on-off routines, different cards, hand-waving incantations + on-off etc. worked. Hard reset with new firmware: worked, but it was not easy to get into the camera’s main menu between error screens–it was like sneaking into a fast-moving revolving door. Sheesh!

  2. I just encountered this error, thanks for making this post for us to read. I tried all that you tried with my A7III, no joy, I was still stuck in the endless loop. But I fixed it a different way, by inserting the card the camera wanted.

    I went through my cards one by one (I have 10, all of which I used the other day), and when I got to the card the camera wanted, it did its “file recovery” thing and then the camera went back to normal (not sure what it actually did, as the card was fine and all photos successfully downloaded).

    I’m thinking that the camera expected a certain card’s serial number, and probably the exact file that it thought was a problem. I fear that formatting the card would’ve left my camera in its endless loop.

    I’m just speculating, but I think that this might have been caused by my camera inadvertently being turned on in my camera bag. The battery was dead when I took it out, and I know I put it back in the bag at around 80% battery. Maybe, because the camera was on, the shutter button happened to be pressed when the battery ran out.

    1. Thanks, Charles. It seems that this unaddressed terminal error loop, not addressed by Sony, can occur in multiple ways, and there is not much helpful content on the Internet that addresses this issue. Again, it is certainly not addressed by Sony. I am glad to hear that you were creatively able to resolve the problem and get out of the frustrating loop.

      Happy shooting. Thanks for sharing your solution!

    2. I thought this was possible, too, but I couldn’t locate the card the camera may have “wanted”–but I thought it was remotely possible the camera really was obsessed with recovering data from one card and would “loop” if it didn’t get it. But frankly, I thought I must have given it the correct card. Again, I solved this by doing a hard reset with new firmware, but it wasn’t easy to get the camera into its main menu.

  3. Thank you for the fix, I was beside myself, it took several tries and I’d just about given up and 3rd time lucky, it cleared. This isn’t the first time this has happened and I can’t understand why Sony hasn’t fixed this bug. Or designed the camera with an external reset option.

    1. Hi Jess,

      Glad to hear you were able to clear this crazy error loop. I agree that it boggles my mind that Sony has not addressed this issues. It also is odd that there just is not much out there in the Internetland on this topic.

      Best regards,

  4. Grateful googler

    You are an absolute life saver. Had this happen towards the end of a wedding on Sunday. I was not looking forward to weeks of being down one body. Thank you so much for writing this up with all of the details.

  5. I have a Sony Alpha R7 III and the same issue just happened to me. I tried swapping cards, but that didn’t work. As you said, the camera was unusable. When I got to my computer, I inserted the card I’d been shooting with (the same one since I got this camera a few weeks ago) and the computer read it, no problems. I then looked for a solution online and found yours. What I did (because I’m awful at following directions):
    1. Used the first USB-C cable I could find (it wasn’t the one that shipped with the camera).
    2. Removed both cards.
    3. Connected camera to computer.
    4. Turned camera on (yes, I forgot to press the shutter button).
    And it worked. Thank you so much!!!

  6. Awesome information Sharing! I had 2 corrupted SD memory card and won’t able to format, I try to reformat the SD card after the drivers update. But Unfortunately, all data lost then I found Stellar Photo Recovery software which help me to recover data from SD memory card. Thanks!

  7. The link to the sony cable is not working, it would be great if you could send me the link to what you got. Terrible timing i know.

    1. your solution did not work for mine. I was at a loss. While the camera was on, without card, I changed from manual mode to 1 and then 2. The dreaded sentence disappeared from the back screen. I depressed the shutter a few times in different modes….And that seems to have cured it. For the moment. Best, F
