Micro SD Card read-only?

Specs: Windows 7, Intel i7 / 4 GB
Ok, I know this seems like a way over simple question, but I have a micro SD card, that I am using an adapter to an SD card, where I am trying to modify the partitions. All partition managers show read-only. I have noticed the switch and looked up which way it should be set to be read/write. I've tried both positions. I've tried using a partition manager with both cards in my phone (which is rooted) which bypasses the adapter. I've also tried using the built in disk manager and MiniTool Partition wizard for PC. I can't write to either card on the PC using the adapter in either position or in my phone using Rheosoft Partition Manager app with a rooted phone. Any ideas what I'm doing wrong?

I tried writing to a micro sd card on my computer that was formatted in my phone and it wouldn't do it. It seemed like an easy way to move media files that I could then text to others. Even changing file attributes didn't help. I didn't delve into why it wouldn't work but since phones don't have sophisticated partitioning and formatting routines I suppose they don't allow fiddling with their setup. There's a good chance that if you were successful in using third party software to alter the partitions your phone wouldn't accept the card anymore.

Another possibility; most phone manufacturer's have PC software that can be used to move files. Maybe software for your phone will allow you to make some changes.

But if space is becoming a problem you may need a second or larger SD card.

Yeah, file and folder attributes or permissions shouldn't make a difference. Now on Windows, from what I understand, it will check the permissions and see you have admin privileges and allow you to do each task. With my phone and root (same as a Unix os), it will see its granted root and then won't even check permissions. As root, it will let me do whatever I want no questions asked as long as I am not breaking some elementary rule of the os.

I've found that some of the adapters you buy on the internet either don't work or are unreliable.

Always pop back and let us know the outcome - thanks

Two things.
Derek may be on to something. Older card readers only read card up to 2 gigs. If you purchased your reader from some unknown source, they may have sold you an older reader that's not compatible with you card size.

If you ever connected with your companies email, they may have encrypted your memory card. Encrypted cards cannot be repartitioned without completely wiping the card and starting fresh.
