Can Not Save

Mattee · 04-21-2020, 06:53 PM

It use to work, now when I try to add a book I get a "Can not save book "........" to device memory. I have a 256 meg micro SD card?
Any Advice?
Thanks, Mattee

How much books are on the SD? How is the SD formatted?

256 MEG? That is an Antique.

I don't think I have ever had one smaller than 512M.
Whatever size, it needs to be formatted FAT32.
If it was supposed to be 256 Gig. You may have a fake (there are a few You Tubes on this fraud)

Then there are problems with about 12,000 books and you have to think up a naming rule that does not result in about 12,000 entries in a folder

Calibre's save template should stop this (in most cases)from being an issue.

Calibre typically uses {authors}/{title} , so each layer gets a limited number of entries. This presupposes that you do (I happen to prefer {author_sort} for file system based bookshelves, YMMV) have a reasonable distribution of Author names

Sorry All Totally Spaced out... Not 256 Meg....256 GB! It is suppose to be Samsung's "Best" High Speed Micro SD Card. Bought it Directly from Samsung. Right now I have about 350 Books.

Mattee · 04-23-2020, 01:30 AM

SD Card usage is 9.8 GB, This Samsung tablet is a bit tricky for me, I'm not sure if it is Fat 32 formatted or something else, searching now?'

Mattee · 04-23-2020, 01:36 AM

Also... The Caliber is working flawlessly, always has. It's the Caliber Companion that has only recently started this... Are the files too large? Trying to shrink them the best I can With Acrobat. Reasonable successful so far. I just noticed when I went through a update of books not downloaded...One of the 15 additional did load yesterday. So I'll try again tonight, since I just made another 15 books of smaller size? Thanks for all your guidance!

this Can not save book "........" to device memory. suggests that CC trying to save to device ( internal) memory, not to card. check your CC settings. if its a 16Gb Ram tablet its probably out of internal space. you can recover a little by removing apps, deletign caches but you need to ensure that books are being downloaded directly to the SD card

theducks · 04-23-2020, 11:49 AM

CC settings allows you to configure per format storage paths.
I believe I saw an option to also move existing books.

Poke around the settings a bit

I have no idea if FAT32 is appropriate for 256Gig (All my large drives are on a PC and use NTFS or EXT4)

See if the CC FAQ [Android] CC suddenly says it cannot write books to my SD card. What do I do? helps.

stumped · 04-23-2020, 12:46 PM

If 1 out of 15 downloaded ok , and all were designed for same folder, then it's probably not a permissions error.
But until you provide more detail, all we can do is guess
E.g.
What version of Android
Is the sd card being used as removable storage
How much actual internal device space is free
What is the save path you have set in cc
( By format, if you have multiple options set ).
What if any troubleshooting have you already tried

chaley · 04-23-2020, 01:01 PM

There is a limit to the number of files that can exist in a FAT32 directory. It is a rather strange limit, depending on both the number of files and the number of characters in the file names.

A synopsis of the details:

There are 65536 entry slots available. A file takes at minimum 2 slots.
The number of slots required equals floor((length of file name + 12)/13) + 1

This limit can lead to strange and seemingly unpredictable results. Deleting a single file with a long file name can allow storing of several file with shorter names. The site https://blog.paddlefish.net/?page_id=1017 is a calculator of the number of files that can fit in a FAT32 directory, assuming an average length. The CC FAQ I referred to above has more detail.

FWIW: CC reports to calibre that all space is internal. Calibre cannot know if an SD card is being used. Reason: CC can control where book files are stored on a format-by-format basis.

he does not say how/where he is getting that 9.8Gb used number from.
AFAIk Calibre [ back on the library PC ] cannot report on space used/space available on the tablet, it has no access to that

i assumed ( maybe wrongly ) that he was getting the 9.8 GB used from an android file explorer app , or from device settings, and that was the total usage of SD card, not usage by CC of card space

but it would still help for OP to post the file path settings in use in the app
and approx how many books on device

speculation about issues with >12,000 books per folder limits may be off the mark if he only has a few hundred books on device. But maybe he is trying download all, to get the entire library. he needs to say

re-skimming the thread, we dont even know if hs is connecting as wireless device or connecting to content server ?

Hi All, as I am at the lower knowledge level of these things, I'll do my best to give a basic setup info:
1 - Samsung Tab A, 16MB (8 MB Actual) with a 256MB Samsung EVO MicroSD Card
2 - I have everything allowed to be, stored to the External Micro SD card
3 - A Caliber books saved to D:Onedrive folder, this is synced to my "One Drive" account
4 - Caliber Companion is linked to the one drive cloud "Caliber Folder" (save to SD Card)
5 - When looking on the Tablets Memory Verification it says (9.8 meg of the 256 used)... Not just caliber, "everything"
6 - So there should be plenty of space?
7 - Download > See Book Image click on it > Download as PDF > Crashes at 40-55%
* Things have been working fine for the past 5-6 months, Problems only recent*
Quess-timation from a confused beginner?
* Internal Memory is the almost Maxed out is it too small to a thru-put data?
* Books too large, tried smaller, but still no download
* Is my incredibly slow internet connection to blame?
Hope this gives some clarity, I'm so confused I don't know what info is actually useful?
Thanks again to you all, Mattee
