USB Hard Drive stuck in read only

[cstegmann]

Hi there.

I cannot modify the contents of the usb hd (150GB). It is read only. Same problem in root. Maybe this is because it was NTFS partitoned under windows. I didn't want to fat32 partition it because i heard that i'd have to split the hd up into smaller partitions since fat cannot support large harddrives.

When i check the permission properties i see that the owner and group only have viewing rights, but no write access. Others are forbidden. The owner is root, and the group is users. I can't change the permissions on the drive, not even as root.

Tried to repartition the drive using fdisk, but that didn't help either.

The drive however works perfectly under windows. No write protection on it at all.

output from df -h
df -h

none 506M 0 506M 0% /dev/shm
/dev/sdc1 150G 75M 149G 1% /media/usbhdd

Any ideas on how i could fix this, thanks.

You can't write to NTFS partitions... Or actually you can, but it's kinda' ugly and I wouldn't even recommend trying it. Use FAT32 if you must share files with Windows...

Sure you can not change permission rights of NTFS since it is mounted as read-only writing NTFS support is experimental and is considered as dangerous.

you can see how the partition is mounted by
