You can learn how to format SD card on Mac as well. I tried it again this time with CLEAR ALL command but met with the same error message.Ĭan anyone please help me be able to format my micro sd card I am not bothered about the data on it as there is nothing important on it. Step 10: Finally, type format fsntfs (or format fsfat32) to format the partition to the desired file system. After about 5 minutes of the format bar not moving it said windows was unable to format, after have a bit of knowledge about computers this means that it is most likely corrupt so I tried something else, I went on to CMD (Admin) and went onto my sd and did the chkdsk command but my hope was short lived after about 10 seconds later I get an error saying something along the lines of 'unable to run chkdsk because the file type is raw', I tried another option which is to use disk managment which said it worked to format but when I tried to allocate it a primary partition it said 'data error (cyclic redundancy check).' so I tried the last thing I could think of the command DISKPART so I selected the sd card which was drive 3 and then typed command CLEAR but after a minute or so I get the same error which is 'data error (cyclic redundancy check)'.

I was a bit confused at first but seen as though I don't have very much important data on it at all I decided to go ahead with the format. Get access to a USB Flash memory without using a computer Mount popular file systems HFS+, extFS and Microsoft exFAT/NTFS/FAT32 Open files directly from USB. I have a 64gb Samsung evo Micro-SD card and have had it for a few years, recently my Samsung Galaxy S7 stopped detecting the SD card, after many restarts, I plugged the SD card into my PC and it said I needed to format it before I was able to use it.

Before I start I should say I should probably post this on the Microsoft forums as well but I want to post it here first.
