Is there a problem with firewire external hard drives?
A new external firewire/USB combo HD with ext3 partition on Ubuntu 6.10
The short version:
copying a large file (>2G) via firewire made the drive dummy
spit. Copying the same size file via USB works.
rsync'ing 60G to an HFS+ partition via firewire on Macintosh
worked fine, so it wouldn't seem to be hardware related.
The long version:
[EMAIL PROTECTED]:~ $ cp verybigfile /media/ieee1394disk/
cp: writing `ieee1394disk/verybigfile': Read-only file system
[EMAIL PROTECTED]:~ $ ls /media/ieee1394disk/
ls: reading directory /media/ieee1394disk/: Input/output error
[EMAIL PROTECTED]:~ $
I couldn't umount/remount - had to switch the external drive off and on.
dmesg says:

followed by lots of:

The failure happned after 1.2Gb and in another attempt at 500Mb.
The USB copy went to completion at 2.8Gb.
