Jake Heffernon Posted April 27, 2018 Share Posted April 27, 2018 I've noticed I'm missing music. My SD card gets unmounted from time to time for no apparent reason and I'm wondering if that would cause this issue or not? Like does it delete the file on the SD card or is it just Poweramp not being able to recognize it? This comes up when I press full rescan. Link to comment Share on other sites More sharing options...
flyingdutchman Posted April 27, 2018 Share Posted April 27, 2018 When your sdcard is no longer mounted, Poweramp and android will rescan and as it no longer can find the tracks on the card, these will be removed from the media databases and so your playlists are no longer valid. Once the card is remounted, the reverse process takes place but the tracks will be treated as newly found tracks . Exporting your playlsts as .m3u8 will preserve them, even after a sdcard removal. However, the above does not remove tracks themselves. It could be though that when your device disconnects the sdcard, some corruption takes place and some tracks are lost. Have a look in the LOST.DIR folder on the sdcard as this is where android will write corruptions. Link to comment Share on other sites More sharing options...
Jake Heffernon Posted April 27, 2018 Author Share Posted April 27, 2018 OK where do I find that folder because I can't find it Link to comment Share on other sites More sharing options...
flyingdutchman Posted April 27, 2018 Share Posted April 27, 2018 It may vary from manufacturers but it is usually found on the external sdcard http://www.piyushdangre.com/2014/06/all-you-need-to-know-about-lostdir.html Link to comment Share on other sites More sharing options...
andrewilley Posted April 27, 2018 Share Posted April 27, 2018 Can you still see the actual song files that Poweramp seems to be missing on a rescan if you use a File Explorer app (even the system one would do, although I use a third-party one).

Jake Heffernon Posted April 27, 2018 Author Share Posted April 27, 2018 Well I just put the SD card into my computer and used a music app to locate all the songs on it and it matched what Poweramp said. So I'm guessing it happened from corruption from my SD card being randomly ejected. So annoying how it does that. Link to comment Share on other sites More sharing options...
andrewilley Posted April 27, 2018 Share Posted April 27, 2018 Could be that, yes. If you can't recover anything from LOST.DIR then I would suggest reformatting the card and copying everything back again from your computer, to clean it up tidily.
