All Hard Drives are Read Only

[Netzilla]

I am completely new to Linux and am running KNOPPIX off the live CD to give it a trial run. So far everything has been running smooth, however there is a significant problem that I'm not sure if it's something I'm doing, KNOPPIX is doing or a hardware incompatability. All of my hard disks are Read Only even though only the Windows partition is actually NTFS. All are IDE.

When I attempt to save anything, here is the error message I recieve:
"The document could not be saved, as it was not possible to write to file:///media/sda5/Linux%20Printer%20Driver.txt.
Check that you have write access to this file or that enough disk space is available."

I have run the following diagnostic commands (unfortunately I can't make much of them myself as I'm not familiar enough with Linux):

Thanks in advance for your help.

Yup. And with NTFS they should stay that way. See answer #6 (http://www.knoppix.net/wiki/User:Harry_Kuhman).

Only the Windows partition is NTFS. The other 5 are FAT32.

Everything in Linux mounts Readonly by default. This is a saftey measure and is completely normal.

To change a drives Read/Write status.... right click on the drives icon on the KDE Desktop and choose "Change Read/Write Mode"

Be warned as Mr Kuhman stated above and in his Wiki that writing to NTFS is probably not a good idea. Although as I understand it with Knoppix5.1+ it has gotten better.

I have been having a similar issue. What i am trying to do is copy files from my HDD to a USB flash drive. even if i change the permissions on the flash drive to 777 when i attempt to copy/paste or drag/drop from my HDD to the flash drive i recieve an error similar to " You cannot copy files to a directory that you do not have write permissions to" ( or something to that effect).

What is the linux command to mount a drive with write permissions?

Thanks in advance,
D

Hi,

I am using knoppix v4.02, and was having this same problem.

I found that the right click gave a drop-down list... select "properties". A window appears... under the 'permissiions' tab, select "read & write" for the appropriate user(s), then select the 'device' tab and remove the tick from the "read only" checkbox.

Not as simple as onemyndseye first suggested. What version are you running onemyndseye?

It took me hours to find the thing under the 'device' tab, and very frustrating hours they were!
