Re-formatting Micro SD from Bootable

Awhile back I make a bootable android version on my micro sd.  I decided to get rid of it, and I want to use it as a normal micro sd in my nook.  Yet, I can't seem to get the nook to recognize the card.  I see that there appears to be two partitions, one for about 7MB and the second for 7.4 or about, GB.  I've tried formatting the card but to no avail.  I even tried merging the two, using EASUS, but that doesnt give me the option to merge.  I think my issue is I need to merge, to get rid of this first partition, but can't seem to figure out how to do that.  Or there is something else I am not understanding.  Any suggestions?  Or give up and buy a new sd card?  .....  thanks for any assistance.

Download SD formatter from here: https://www.sdcard.org/downloads/formatter_3/ and format card on your computer, then put back into NC.

Mike --

 

You're on the right track with EASUS.  What I found was that to get the full capacity back, I needed to delete all the partitions on the card and create a new partition, then commit the changes. 

 

This is enough of a PITA that unless I have a spare 8G card around, I'm not bothering with CM7 or 9 - I booted cm9 once, thought "it's an alpha;  it works, but either I don't have drivers yet and the OS is still using MTP, or the OS doesn't have the 'talking directly to the host computer' part baked in yet."  When I had a spare card, I tested cm7 and miui, then went back to rooted stock, but to recover the card, I always needed to blow out all the partitions and start fresh. 

 

EASUS was the only Windows utility I could use to delete the linux partitions on the Verygreen disk, and my memory is that my linux box couldn't take care of them, either.

I imagine a bootable CD to GParted would work as reads ext linux partitions as well as windows partitions.

Re: Re-formatting Micro SD from Bootable

Orb and roust are taking the long way around. Savoir_Faire's suggestion of SD Formatter is the simplest way to go.

 

You can delete all but the "sdcard" partition in your partition manager of choice (EASEUS, Gparted, etc), extend that one to take up the unallocated space, and then format by whatever method, but SD Formatter will do it in one step.

Re: Re-formatting Micro SD from Bootable

sometimes, the easiest way is to put the card in a dumb device, like a camera, or camcorder that cant read the format, and will want to reformat the card, then let it.  The type format the card needs is "low level formatting", so trying to format from windows explorer wont do it.    One can always visit the web page of the card manufacturer for  a utility, or a recommendation of a tool to re-initialize the  card.  There is a tool in the windows system32 folder that can do this, but, you are better off not using anything directly from that folder unless you are a very experienced tech.

Re: Re-formatting Micro SD from Bootable

SD Formatter is the industry standard for formatting SD media. It is the recommended tool in Windows or OSX, regardless of card manufacturer. If you use SD cards, you should probably keep it around.
