Hmm.. thats odd, since the sfdisk command output you showed bfore said it had no partitions on the device... Yet now it's saying it has a partition mounted. Well, this should do it for you:

Code:

umount /dev/mmcblk1p1

sfdisk /dev/mmcblk1 <<EOF

,,c

EOF

sync

mkfs.vfat /dev/mmcblk1p1

sync

sfdisk -d /dev/mmcblk1

The output the the last command should show you have a partition, formatted properly. Then a quick reboot (or open your back cover and replace it) and you should be all set.

Ok did everything you typed and does it look ok? Will reboot after you confirm.

Code:

/home/user # umount /dev/mmcblk1p1

/home/user # sfdisk /dev/mmcblk1 <<EOF

> ,,c

> EOF

Checking that no-one is using this disk right now ...

OK

This does not matter for LILO, but the DOS MBR will not boot this disk.

Re-reading the partition table ...



If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)

to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512 count=1

"umount /media/mmc1" should do it.

Will do after woody14619 confirms my previous post.

Thanks!

Re: 16GB miniSD issue!!! HELP!

You look good... I'd say reboot and trying writing to it. That should put everything into a working state.

I think I see part of the issue. The old one was formatted as type b, not c. The difference is one uses LBA, the other does not. Shouldn't make a huge difference, but if the devices read the card slighly differently, the LBA version should help.

One thing to note: This is formatting to Fat32. That means you can't store a file on it larger than 2Gb, regardless of the size of the partition. (That's a FAT limitation, no way around that.) Otherwise, anything under 2Gb should store and work fine.

Re: 16GB miniSD issue!!! HELP!

Alright, it looks like I could write to it, I could before but they would disappear and get the corruption error. Anyway, I copied my videos folder to the memory card but for some reason they don't want to play correctly. It doesn't feel like it's a 100%. :(

EDIT: I just attempted to delete the videos folder I copied. It deleted, closed the box, reopened the media manager ...the folder with the videos are still there. :confused:

Re: 16GB miniSD issue!!! HELP!

Back to the beginning! I really thought this would of fixed the problem. :(

Re: 16GB miniSD issue!!! HELP!

Had a similar problem before - and I never found a fix for it, either.

Just seems like the N900 is a bit picky which cards it will accept. The card in question now happily lives inside my XPeria, while the former XPeria card now works like a charm within the N900. Had no problems with either onr since then - but I'm sure if I switched again I would be back to my read-only problem.

Re: 16GB miniSD issue!!! HELP!

Nathraiben,

I think I'll do a switch with my 16 with my brothers 16 and see what happens.

Will report back.

I would like to thank everyone who replied and tried to help me. If anyone got a solution please post.

EDIT: You could be right about the N900 being picky when it comes to these memory cards. I inserted my sisters 2GB and it worked flawlessly. The videos played smooth depending on which media player I used, but still quite smooth.

My 16GB has a 2 in the corner and it says HC on it. I have no idea what those stand for. My sisters 2GB is just plain sandisk SD card.

Don't know if this applies to your circumstances or not. I didn't see this mentioned previously, I may have missed it.

The HC is high capacity, in excess of 2 gigabytes. The 2, 4 or 6 has to do with transfers speed possible with the microSDHC card. I saw this mentioned above so I am addressing it.

Re: 16GB miniSD issue!!! HELP!

tzsm98,

Oh ok, I had a feeling that's what it meant. Thanks for the reply.

Re: 16GB miniSD issue!!! HELP!

Interesting, so in both cases we're talking about a 16GB microSDHC 2 not working.

(The one that works with my N900 is a 8GB microSDHC 4)

If you happen to get access to your brother's card, maybe note down the data transfer rate for that one, too.
