can't write or delete from sd card
Code:
mount |
Look at the ownership and permissions of the mount point.
ls -ld /media/E0FD-1813 I'm wondering if the filesystem might be corrupt, or if you aren't the user with the UID of 1000. The dmask only allows the owner to enter the directory. The fmask isn't listed. |
I was root.
I will try 'fsck.vfat -a /dev/sdd1' |
I had this problem also. What I had to do is as root mount it to a user.
This may help: thanks to spazticclown Quote:
Hope it helps |
The pendrive was mounted as the user with the UID of 1000, which would be the first regular user.
Post the ls command results. The missing fmask mount option seems abnormal. Your regular user will be able to access the directories however according to the dmask used. Try reading and writing to the disk as a regular user, as you should be doing. |
Code:
$ mount while E0FD-1813 is SD card with same mount options yet immutable. |
Some SD-cards have a little switch to make the card read-only, you should have a look at that.
|
The SD card is simply fitted in mobile slot.

That image explains your point.
Nothing on card. It is same as bottom one on http://upload.wikimedia.org/wikipedi...7/SD_Cards.svg |
'fsck.vfat -a /dev/sdd1' corrupted the file indexing by samsung OS of mobile by renaming files with non graphical characters.
The mobile manual had initially warned to format the micro SD card only with samsung OS But I edited file system without heeding to that. Yet 'read only file system error'. |
Having graphical characters listed for the filenames indicates the either the filesystem is corrupt, or the SD card is going bad.
If fsck didn't fix the problem, you might need to use photorec to recover files on the filesystem before reformatting. If reformatting doesn't help, I'd say the device is going bad. I had a similar problem yesterday with my kindle. I couldn't save items in Calibre with the same error message. Fsck fixed the problem for me. You may have had more extensive damage to the filesystem. |
Turns out the samsung OS in mobile creates file with non-ASCII names , maybe not adhering to FAT specification .
'fsck.vfat' was exhausted (1/2 hour up still working) in renaming those garbled folders. Also 'find' indicated filesystem loop detected. Those mobile OS software engineers cover up flaws with patch & label unintended bugs as security features.-Said by Dilbert That is why they warned against formatting on computer instead mobile OS can do that. Also it seems files on micro SD card get corrupted soon unlike USB stick. |
