How do I get out of Read-only?

[Skahl]

I am using the Hinsdale Upgrade instructions and cannot get out of Read-only mode.

I am trying to do the following command:mfsbackup -f9999 -6so /mnt/dos/tivo.bak /dev/hdd
It returns the following:/mnt/dos/tivo.bak: Read-only file system

How do I get it out of Read-only?

Thanks

Did you actually create the /mnt/dos directory and then mount /dev/hda1 to the directory before attempting the backup? /dev/hda1 is your FAT32 drive installed as primary master.

I did create the directory and mount to the directory before attempting the backup. I was trying to use my secondary drive of my computer as the primary master when I get this error. I don't get the error when i use my main computer drive as the primary master. I was trying to use the secondary drive of my computer for the backup file since I didn't have enough space on my main drive. Since I couldn't figure this out why it was doing this with my secondary drive. I have since moved some files to my secondary drive and deleted them on my main drive to make more room. Now when attempting a backup, it still fails after copying ~10%. It reads the following:
Backup failed: /mnt/dos/tivo.bak: Success

Is your secondary drive NTFS? NTFS is mounted R/O by default in most Linux boot CD's.

The TiVo image file will be around 100M you need at least that much space I would allow at least 250M.

Were you getting errors from the TiVo your drive may have some bad blocks. You might be able to image copy the drive using dd_rescue. You also might check the drive with the drive manufactures diagnostics.

Suggest you use the MFSLive (http://www.mfslive.org) CD the Hinsdale instructions are out of date and do not work well with large drives.

The size of the TiVo's drive and model of TiVo could be useful.

Both drives are NTFS. Do they need to be FAT32?

Yep. Linux can't write a backup to NTFS.
