H2O Error& Fade

Lemons · 12-05-2014, 04:45 PM

So after a few day's with the H20 I am starting to notice problem's one is text fade, like I can see some words like this Apple where it is very faint, esp when I open it up.

The second problem I was curious what the issue is with Calibre. My pc detect's the H20 and the MicroSD card fine, although Calibre does not and gives me this error instead

However if I system restore the device, Calibre detect's both the H20 and the MicroSD card fine and I can move books to it, it is only when there is a book on it, that it gives this error so I have to system restore the device again to put another book on it.

calibre, version 2.12.0

It looks like you need to check the permissions for the file driveinfo.calibre on the Kobo and set them so Calibre has permission to write to it.

jackie_w · 12-05-2014, 05:44 PM

... as for the 'text fade' issue. Go to Settings - Reading Settings and look at the value you currently have set for 'Refresh the screen every:' Try reducing it to '1 page' if it isn't already.

how would I go about doing this? I'm not very smart on how to do that and there is no files on it when i connect to it, and I think it already has premission because I can put book's on the device when I system restore another after I disconnect / reconnect I can not

If I understand the last bit, you did a factory reset, connected to the PC and put a book on the device. You then disconnected and reconnected and the book and all other files were missing? Plus you couldn't copy anything to it?

If that is correct, someone did have this problem a little while ago, but I think it was with an Aura HD. If I remember correctly, it turned out to be a faulty device and they exchanged it. Before that, can you try a different cable, different USB port or another PC? It could be any of these, and if it is, you can avoid returning it.

What is your computer Operating System and Version?

What I have to do is do a system restore, following that the program detect's it fine and I can move books to the device (It gives a error at 100% but it still sends the book's) following that if I disconnect the cord after ejecting it then plug it back in the program will give me the error again until I do another system restore and I am using windows 7 64 bit

The books already on the E reader stay's on it expect for when I have to system restore the device to be able to connect it if that makes more sence and i tried most of that

JSWolf · 12-05-2014, 06:43 PM

Are you properly ejecting the H2O from the computer?

Check the permissions for driveinfo.calibre that is on the H2O (I think in the root of the H2O).

yes I eject it from calibre 64bit and also tried the windows eject but no matter what I can not connect to calibre once there is files on it, Found out how to do the files and all of the box's is unchecked, but I tried to check one of the files to see if can be played with and gives me an error driveinfo.ink the system can not find the file

That's not the error you are getting. You are getting a permission error with driveinfo.calibre on the Reader. Check that file's permission. Also I suggest running chkdsk on the Reader and see what that says.

Firstly lets deal with some terminology. For a Kobo device, I have no idea what a "system restore" is. I do know what a "factory reset" is. This can be initiated from the "Device information" page of the settings or from the powered off state by tapping the bottom corners of the screen. Is one of these what you did?

Yes, I am probably being pedantic, but, if you mean something else, we need to clear that up.

Forget about calibre at the moment. The error you are seeing in calibre is a symptom of something else. If Windows can't see the books on the device when you reconnect, then calibre will have problems as well. And this is where using another PC is a good idea. If it happens with both, it's probably the device. It it is only one PC, it is probably the PC.

What happens if you power the device off and on? Do the books still show? Can the PC see the books?

I'll try to make it more clear, I Did do the Scan but there was no Errors so but yes it's a factory reset back to the start, where it delete's everything off from the device.

As for seeing the file's through windows I can only see that one file told me to check the premission's on, although I can see all the books in the Kobo reader and read them just fine, it just will not connect once there is a book on the device to calibre although all the books stay on the device

when I do the factory reset, I can see through Calibre and I can add book's to the device and remove those book's it is only a one time thing however before I have to factory reset to be able to do it again, thats why it sounded like software to me. I can never see the book's through the pc in Mycomputer but no matter if i shut the device off or not they will remain on the device until I do a factory reset

Ok, you do a factory reset, connect to the PC and everything is OK. Disconnect, and the books are there. Reconnect and nothing is shown. Correct?

Unfortunately, this could be the a number of things. But, the one thing it is not is calibre. Calibre relies on the OS and the device talking to each other properly. That isn't happening. The only way you can blame calibre is that when it is getting the book list from the device, it is doing a lot of work over the USB connection. That might break it, but, if it does, it was teetering on the edge anyway.

So, we need some troubleshooting. We need to eliminate possibilities until we can fix it:

- Do you have another PC to try? Or cable or USB port? Each of these could be the problem, so we need to check.
- Have your rebooted the PC?
- Get USBDeview. When you run it, it displays all past and current USB devices. Find the references to Kobo, select them and delete them. Then rebook the PC and try again.
- What happens if you manually copy a book to the device? Does the device see it? Can you see it on the device at the next connection? Can you copy another book or delete that one?
- Have you installed the Kobo desktop application? What happens when it tries to see the device?
- After the factory reset, how do you setup the device? Over WiFi or by connecting to the PC and the Kobo application?

Hopefully something in that lot will help. If it all fails, then it probably is a faulty device and you should return it.

This is correct, kind of. I connect to the Pc everything is ok so I move books onto the H20. Then when I Disconnect everything is still there all the book's is still there on the Ereader.

When I reconnect though I get that error above in Calibre ^ although it does not effect the book's on the E reader, they still are on the book, the only way to re connect to Calibre is to factory restore.

I have tried another cord, and another USB port, I don't have another pc to try it on i'll try that method but I have always restarted the pc numbers of times and it never could detect the E reader after it has files on it. though I never tried to manually copy a book to the device as I am not sure where it would go on it and I set it up by Wifi

As for the Kobo desktop ap the H20 does come up on the last tab EReader although Libary is grey'd out and shows the last book added and all that good stuff.

Edit I just tried my bf's laptop and it gave me the same error, so it's prob the device

Yes, with all that, it is the device. Get it replaced.
