Windows 7: Need to erase a drive/unite drives on my SD card

Need to erase a drive/unite drives on my SD card

Hey,
Got this 8GB SD, which serves my son's Android phone.
Now, for some reason, this SD is divided to two DRIVES (not partitions, drives), a 3GB drive and a 5GB drive. The phone treats the 3GB drive as its first and default drive.
Now, I want to reformat the SD in a way it'll include a single 8GB drive. Then I can repartition it the way I like.
Problem is that I couldn't find a single tool which does that. Whenever I try partitioning the SD with any of these tools, it detects 2 separate drives, on which it can perform any partitioning function, but all within the drive itself. No tool offered the option to erase a drive or merge drives. I could also do with a tool that turns the SD blank or return it to its factory settings. I have tried Windows tools with card readers or with the SD inserted in my phone (MSC mode) without any luck. Also tried some Android tools, no help either.
Would appreciate any help here.
Cheers,
D.

Wecome to SevenForums Digdis,

I had never before put my thoughts into partitioning SD Cards ( he!) and wasn't even aware of it so to say. Can of course be excused since I never had an Android phone - moved to my first Windows 8 Nokia Lumia 520 Smartphone only recently.

Anyway I think you can try MiniTools Partition Wizard Home Edition 8.1.1 to delete the partitions ( whether you call those partitions or drives it is all the same) and recreate partitions (drives) of your choice. Free download Magic Partition Manager Software, partition magic alternative, free partition magic, partition magic Windows 7 and server partition software - Partition Wizard Online

SD partitions can be managed with the partition manager Partition Wizard.

Thanks for the quick reply, Jumanji.
In fact, the minitools partition wizard was the first tool I tried. Alas, it was all the same as other tools I have tried afterwards - the tool displayed 2 separate drives (not partitions). Therefore, I could not erase any of the drives (unlike the partition case).

May be I am way off the mark - atleast in this case - when I said partitions and drives are the same (tuned as I am to conventional partitioning.)

Does your SD card show as two different physical drives?

Can you post the screenshot of how the SD looks in Windows Disk Management? ( Please remove all other external drives.)

Attached the disk management screenshot. Please notice disks 1 & 2 (drives E and F) - these belong to my SD Card. Notice that Disk 1 (E) is internally partitioned. This is deliberate and OK (was required for some android application I was dealing with), but has no relevance here. Point is that the SD card has two separate drives, not partitions.
Just a small disclaimer: I can see this with the phone connected to my PC in MSC mode. I should get a hold of the card reader today, in order to see whether it's viewed differently. I suspect that the results will be the same.

OK, Thank you for the nice screenshot.

Now everything is clear.

I also understand that is with your phone connected directly to the PC and the Disk Manager in it (the phone) or whatever that is doing it.

And yes, let us see how it looks through a card reader.

My own perception is that it is going to be different obeying the normal laws and you should be able to delete the volumes and make it one drive - not the Microsoft one drive

OK, so I connected it via the SD card reader. The one I've got has 6 slots per card type (SD, micro SD, CF etc.), so when connected to the PC it creates a drive per slot. Therefore, I can only see the first drive (the 3GB one) with this reader. So - maybe I need to try another reader. Should take a bit of time.

Yep, on a multipartitioned SD card Windows will see only the first partition.( That escaped my mind.)

Run diskpart clean all and it will zero all sectors and then your full capacity will be available. After zeroing format the SD card. Make sure you choose the correct disk to zero.

Thanks Jumanji.
Just to clarify: When in the SD card reader, I see the first drive but with all partitions inside (as in disk E in the screenshot). Only thing I don't see is drive F.
Anyway, I will try this utility later on today.

My brain cells are overloaded with so many things they refuse to understand anything .

May be seeing a screenshot will help. Also let it be recorded here.

In any case run the clean all command on the correct drive.
