Hey guys/gals, I was having that problem with my phone where it would say please insert sd card but the sd card was in the phone. I couldnt take pictures, download anything, listen to my music, view my pics or videos. It was so frustrating. When I looked at how much space I had left, it was showing Unavailable under the Total and Available Space My phone wasnt recognizing my sd card. I turned off my phone and took the battery, sim card, & sd card out and left them out for like 30min, like 10 times, and it was still showing the same thing each time please insert sd card I called TMobile, did all the trouble shooting, factory reset and all. Didnt wrk, so they sent me a replacement phone. Still the same problem, so now I knew it was the card, not the phone. To be sure it was the card, asked a relative to see if my sd card wrked in their phone, and it didnt. Said his phone was saying sd card damaged So I was bummed cause I thought I was going to have to get a new sd card, and lost all my pic/videos on old one.
Note: Relative told me sd cards can get damaged from unproperly disconnecting them from computers, and not unmounting the sd card from phone before taking the sd card out of phone, which I was doing, and to start disconnectiong phone from the computer by using the safely remove or eject action before I take the phone off the SUB cable and unmounting card from phone before taking it out.
I took my sd card out of my phone and left it out for the whole day(didnt think I was gunna use it anymore). Still could use my phone and internet. I installed an anti virus app called Dr. Web Light did the full system scan, no detects. Noticed the quarantined files folder, tapped it, said sd card is missing. Quarantined threats cannot be viewed So I put my sd card back in my phone to see if I can run a scan on it and see if any threats came up. Still couldnt view pics and stuff. Ran the scan again, and when it starting scanning the sd card it slowed down ALOT, I thought it was going say threats were detected, but no threats. Then I went to sd & phone storage in the settings, and under the Total and Available Space, it went from Unavailable to 2.53 GB so that told me it was reading my sd card!! I went into my pics, I COULD VIEW MY PICS AGAIN, AND VIDEOS AND MUSIC!! YEYY!! I dont know if the scan forced my phone to recognize my sd card or what, all I know is that after I ran that scan, my phone was recognizing my sd card again. YIPPEE!! Thank you Dr. Web Light.
I hope this helps. Good Luck!!
Hi I have the same problem which started just suddenly after my battery was drained. After recharging the SD card kept failing. My phone is HTC desire from 2009 but this is the first time it happens. I tried the suggestion above but didn't work. Help please
I just got an HTC ONE SV, and I had been attempting, via~ the SD Card, purchased at the local, friendly Walgreen's to transfer Pix and Vids, etc. Now, both phones will not read the card, alleging it is damaged. This was also after I encrypted it into the new phone, and did not disturb it for over an hour as prescribed. Very frustrated!!! If there is anybody out there that has any quick, and helpful tips, I'd appreciate it. I also, then attempted to put the Micro-SD Card into an adapter and upload the data to our laptop, to no avail, mostly because it indicated the card must be formatted first, but I was told earlier that if I did that, all the information would, or could be lost. PLEASE HELP! Thank you.
