I've gone through three attempts now to get Time Machine to back up my data to an external USB 2.0 IDE drive. On each attempt I reformatted the partition on the target drive to MacOS Journaled. TM either stalls during the backup (after backing up around 23 GB on my machine) or quits with a message like "Backup failed". When it stalls, there are no more writes to the external drive (checked with activity monitor) and the progress bar doesn't move for hours. It is not possible to continue a failed backup, TM just stalls and doesn't copy anything. What can I do in oder to finally start using TM?
