I've had my Android phone running Android 4.4.2 KitKat (rooted) for around 5 months. It has been working fine. That was until a few a days ago, when the external MicroSD card (I presume), which I use and have used many times as the default install location for apps and other data, started acting funny. By acting funny, I mean I can delete files and move them on PC or the device itself (which I randomly can't sometimes because of unknown error in FXEplorer for Android, with root access), but upon remounting, they'll be there again, in their original location, undeleted. It's like I'm deleting a file to which the filesystem has no true handle or something. Also, I noticed that one timem when I mounted the card, there were sh*t tonnes of files with garbled names like "&%$$ !00_3&&@3" in one folder, so much so that it took forever to load up the file list. When I remounted, they weren't there.
In addition, apps which used to work are saying "App not installed" upon trying to open them (most are installed on the SD Card), or crashing upon certain tasks (presumabley because it assumes a writeable sd card, when it is really sometimes read-only for no reason).
I only have one guess as to the cause but I have a strong feeling it is. I recently (a few days ago) transferred some folders, each with very long folder and filenames inside, onto the sd card from my PC in USB Transfer mode, which I have successfully done many times prior. I'm assuming the files/folder/path names were too long and this may have caused corruption of some kind, perhaps to tables or indexes or the filesystem in some way but then again, I know nothing about any of those.
I thank you in advance for reading this long-winded question.
