Hello! Solution here:
Hello to everyone, i found a real solution to this problem, but if you follow this steps you are going to lose all files on your e-reader, so if you donīt have a backup of your books, donīt do this. Donīt need open your kobo all is for software.
First of nothing, i donīt very good with english (i speak spanish), so please donīt kill me for my redaction. I discover this steps for myself, triying and triying. 1.Download this program and install http://www.minitool.com/partition-ma...zard-home.html Itīs a free version. 2.Conect your Kobo to your computer and open the program. 3.You are going to see all disks and devices on your computer, select your kobo (You can see the size to be sure). 4.Right click and select "Format". In the options put a name (or not) and change File system to FAT32 (Donīt select any other!). After that, click on Apply (on top-left). 5.Wait a little. When the process finish your computer now can recognize the device, but donīt move any file yet! 6. Disconect your kobo and turned off. 7. Turned on, you are going to see the first configuration, configure your device (Wifi, time, account...) 8. Thats all! now you have your device like new, you can add your books from computer without problems. NOTE: If you do a Factory Reset in the future, you need to do this steps again, beacause Kobo devices reformatted the internal storage and for that reason the computer donīt recognize. Well, thats all, if you see other people with same problem, please share this solution. |

It begs the question of why it has started failing in the first place. The factory reset formats the user partition with: Code:
mkfs.vfat -n KOBOeReader /dev/mmcblk0p3 && sync && sync |

Oh well, if formatting really solves it, that's fine too. |

Difference between two calls:
Code:
# cmp -l /tmp/[ab] 490 241 67 491 216 276 492 14 13 493 74 113 494 2 3 |

Given the above steps to get your Kobo to work with Win 10AU, after step 5, would it not work to restore the backup you made before installing the AU? Then you have al your books, annotations, bookmarks, etc.

That's a reasonable assumption. I wonder what the rest is. A timestamp would be the obvious thing to write, but I can't think of how to decipher it.

But to do that, you have to do the backup before the upgrade. And as most users won't have had a reason to do that, it isn't going to help many people.

Thank you enigmedark
Hello everyone
Thank you so much enigmedark. Reformatting Kobo eReader with minitools partition wizard worked for me. I could reinitialize my reader properly and access the directory as before. |

And does the Kobo Desktop application, and Calibre, now recognize your Kobo, so that you can sideload? Or is it simply that Windows sees it properly now.

If Windows sees the Kobo properly and Calibre does not, you just follow the directions to report what Windows does see so Kovid can fix it in Calibre. Problem solved.

I was also looking at the discussion about bytes in the first sector of the drive changing. As near as I remember the layout of the MBR, the bytes being modified are the last 4 bytes of the 3rd partition entry and the first byte of the 4th partition entry. The last 4 bytes are, AFAIR, the number of sectors in the partition while the first byte is the status of the partition so we are mucking with the size of the third partition and the type of the 4th. Makes me wonder if Microsoft is now doing more error checking and seeing that modified MBR as being invalid. Last edited by DNSB; 08-05-2016 at 03:19 PM. |

Since most USB devices are partitioned after all, I wanted to change it so it would export with a partition table (with one partition pointing at the FAT32 partition) and see if that helped somehow. But so far noone volunteered for the experiment. Ah, maybe I should install Windows 10 in a VM somehow and see if I can test it myself after all. Then again I don't care quite THAT much about windows problems * If you're using Windows to format the Kobo, you must be careful not to create a partition along with it as the device is not supposed to have partitions. Filesystem must be directly on the device itself, no indirections. If you do it wrong the Kobo will factory-reset the hell out of it. Last edited by frostschutz; 08-05-2016 at 03:45 PM. |

If I had access to a Win 10AU, I could give my H2O a format and use for a while and then see if Win 10AU still properly sees it.
