...Raspberry Pi, I used it to install to OS on, now ive went to put my music back on for my phone and it say 1.56GB in total... the Micro SD card that came with the PI off a friend (whom im trying to set it up for) had a 16GB card in and loaded kodi only (KODI OS), i couldnt its SD get it to work in the reader in my PC or via a card reader... mine neither... but last night it MINE was 16GB in my ph0ne full of music, i deleted it, put the raspbian noob install files there, installed in, now I found out i need to reinstall the OS just to bloody change the resolution of the screen... so when i went use my now empty SD card again in my phgone on PC it says 1.5GB??? its empty and you can not see it in disk manager... it IS a 16GB card... but something has happened to it in this raqspberry Pi I think

sick of my life...trying to help people for free n completely going backwards after backwards..

any ideas?

thanks

Could be an incompatibility or damage to the card but also these micro SD cards aren't designed for sustained write usage - 24x7 sustained write use for instance will see the number of available write locations start to drop and hence capacity decrease after 3-4 months - that would need some pretty heavy use though to see it reduced to 1/10th its original size.

I havent sustained write usage on it though..the music on it was there for years... so its only beed erased one then files put on - im aware of write usage on eMMC n SSD

but now BOTH cards a broken...one (his) doesnt show at all (but did on my phone), now mine does but at 1.56GB>?

icompatibility? it doesnt say you can use certain types of card? its only 16GB

its a 2B+ 1.1 (not that I know much about them)

Have you downloaded/used the SD formatter tool? Your OS install could have set up partitions on your SD card which you can recover with that tool.

The exFAT file system can occasionally result in some strange behaviour and on a related note the fact it uses 128kb block sizes can catch you out if you are trying to copy lots of small files from a 4k NTFS partition :s - had 10GB of files using 40GB that way the other day lol - but back to the point try formatting it to NTFS and then back to exFAT (if desired or whatever other FS you want to use) I've had that clear odd behaviour on SD cards before - including as above make sure you wipe out any extra partitions, etc.

Also, on the note that the SD card that came with the Pi didn't work on your PC.

It's probably ext4 formatted if it's been used in a Pi (or has been formatted for use in one) and that's not readable by Windows without a 3rd party driver. There are some available for free with a quick google, so that might help you.

The size issue could be as simple as a FAT partition showing up and the rest of the space hidden in a ext* FS you can't see.

yeah realised after i installed EaseUS Partition Manager, so Im all sorted with RASPBIAN and have the correct resolution, but is it possible to install KODI as a separate program on RASPBIAN as we would like to take advantage of RASPBIANs other features and maybe install a couple other things?

just KODI page leads you to LibreElec which is basically a KODI OS for Raspberry - so you can only have KODI when booted

thanks
