I'm hoping you guys can help me a little bit. But I don't have high hopes for this MicroSD Card.
Problem: My phone reported the MicroSD card as corrupt. Fixed it via a reformat on my Windows machine using an adapter. Put it back in the phone and a couple hours later - corrupt again. Tried having Android fix the SD Card. It "finished" as in it left the screen showing the format percentage. Still couldn't see the storage space on the phone. Took it back out, and tried to reformat the SD card via Windows (again). Windows wouldn't recognize it.
I used Diskpart (CLI) and Disk Management (GUI) to get some information from it. Disk Management (after I disconnected the drive) reported an unallocated 8GB size. This card is 16GB. File System was RAW, which it isn't supposed to be. Moved onto diskpart to try and glean more information. "list volume" done at separated by 10 seconds reported two different sizes. 8GB and 522GB; neither of which are correct. No volume on my system has a size of 522GB. Tried to reformat it with fat32 (and later tried NTFS) File Systems. Both failed. Event Viewer registered 2 warnings (that spammed Logs).
The IO Operation at logical block address xxxx1 for Disk 7 was retried. The IO Operation at logical block address xxxx2 for Disk 7 was retried.
*Disk 7 was the actual disk for the MicroSD Card. I just don't have the blocks. There were only two blocks from the couple dozen I checked.
Tried other systems and adapters (4 systems in total - each tried all 3 adapters). Linux (CentOS), Mac (High Sierra?), Windows (Home & Enterprise) all failed to identify and fix the problem. 3 different adapters were used. 2 Micro to Mini and a Mulltimedia Device - connecting via a USB - (Mini & Micro compatible).
The Enterprise Version of Windows registered this error
The device, \Device\Harddisk1\DR3, has a bad block.
I've had my dad look at it (Virtualization Engineer), and he's run out of ideas.
Looking at a dead SD card or are we missing something super obvious??
