phone dont recognize sd after reboot

My Droid Inc doesn't recognize my SD card after reboot or shutdown and erasing photos. Anyone have a fix for this besides getting new phone?
Tried a different SD card?
I have and it does the same. I can unmount card and then mount it and it reads fine
I had to reformat my sd card within the phone when I had this problem. It seemed to have fixed the issue.

Anyone else having flaky SD card read/writes (requiring reboot to fix)?

Lately I'm noticing that my Nitro keeps losing read/write access to the SD card (says SD card is unmounted and ready to be removed. If you click to mount it says the card is damaged) and I have to reboot for it to work again.
I'm wondering if I didn't hose my SD card during attempts to root. I went through dozens of attempts to root with the SD Card mounted (supposed to be unmounted) and would force close the SuperOneClick app when it locked up on mounting the SD.
I'll give it a good formatting I think, hopefully that clears things up.

[Q] SD Cards

I tried to format my sd cards tonight via computer format option. However my computer shut down in the middle of the process and now I can't see my sd cards anymore. I can't mount it at all. When I go into the recovery to wipe it, twrp says failed.
Does this mean it's completely dead?
solved it.
googled and found this thread http://forum.xda-developers.com/showthread.php?t=1806059 for my internal sd card
and for my external, i used a card reader, plugged to pc, and reformat it.
also checked both cards for errors.
whew. i am never gonna reformat my cards again. ever.

Encrypted SD Card Corrupted from phone

Hi,
I have a 128GB Sandisk SD Card. and had it setup as internal storage.
This morning. I noticed that some of my apps installed in my SD card are missing. so I checked my SD card from my file explorer. turns out it doesn't see the SD card. So I restarted my phone and my SD card still did not get recognized.
Then I removed the SD card and inserted it after restarting. then a message of
Code:
'This device doesn't recognize this Sandisk SD card.'.
When formatting it. I got the
Code:
'command '20 volume partition disk:179,64 public failed with 400 XX Command failed'
Tried putting the SD via OTG and formatting it via that way and I am still getting an error for it.
I did a few research about the error, and said that I can try and format it via PC. then I did go to my PC to format it. On my computer it shows 2 partitions
Tried doing the normal formatting for both of it. One shows 16mb and the other as 119GB. but both doesn't continue and I am having this message
Tried looking at it via Disk Management and can only perform this
And getting this error when trying to do so
Also tried doing it via diskpart and still getting this.
I need help on this. I feel that there is something I(We) can do to salvage this SD card. Any help would be appreciated.
Also, I haven't tinkered on my phone so it's not rooted/flashed yet (hoping that i wont be needing to do this). And the SD Card is authentic as I bought it from a reliable store
