HELP! Can't write to external hard drive

[danmc00]

I have a Toshiba 250GB external hard drive to back up pictures. I can write to it just fine.
I also have a Fantom Drive 1TB external. I could write to it last week, but I turned it on this week and I can't write to it. I can still pull stuff off of it, but I can't write to it. What can be causing this? I have already installed MacFuse and NTFS-3G.
It doesn't make sense to me that I can't write to it all of the sudden.

Open a Terminal window and run this command, then copy the results back here.

ls -l /Volumes

 

[danmc00]

Sorry, but I'm very new to the Mac world. How do I open a terminal window?

 

[BlueRevolution]

It's an application, which you'll find at /Applications/Utilities/Terminal.app.

 

[danmc00]

I tried it two different ways and this is what it came up with.


1s -1 /Volumes
-bash: 1s: command not found
1s-1/volumes
-bash: 1s-1/volumes: No such file or directory

Make sure you type 'ls'. It looks like you typed 1s.

EDIT: You can also copy and paste what BlueRevolution said above

I copied and pasted it this time and this is what it came up with.
The Untitled one is the 1TB external hard drive I am having problems with.

Looks like it's a permissions problem. My time machine drive is drwxrwxr-x. Does root own the disk? You need to post all of the terminal output.

Does root own the disk? You need to post all of the terminal output.

That looks like all of the output to me.

In Terminal again, run:

sudo chmod 777 /Volumes/Untitled

You'll be asked for a password, which should be the one that you use to log on to your user account. Be aware that you can't see the characters as they're typed (not even ******) but it's still working.

 

[mac2x]

That looks like all of the output to me.

Look closely; there is no owner listed on any of the three but Macintosh HD.

 

[danmc00]

I deleted all the owner type. I didn't want to post it on a public board.

 

[danmc00]

Blue Revolution, Here is what I got.

Ah-ha! Connect the drive to a Windows computer or Boot Camp partition and eject it properly, then try again with your Mac.

 

[danmc00]

Why would it just do that all of the sudden? I have been writing to it with my iMac for a month now.

 

[BlueRevolution]

If the hard drive is improperly ejected, NTFS can get corrupted. Windows will automatically fix the problems.

 

[danmc00]

I brought the external to work so I could hook it up to a PC with Windows. I have safely ejected it. I will put it back on my Mac later today and give update.
