Was in a similar situation about a month ago.. I knew the drive was on
its way out but once it went, i could not retrieve the data nor use it
under freebsd even under a new system. My drive had physical issues.
I got the drive, stuck it in a 3.5inch usb enclosure and plugged it into
a ms windows box. Then I used a free proggy called ffsdrv which i found
It enables you to read BSD(FreeBSD, NetBSD, OpenBSD) FFS partitions on
Managed to get all data off this way.
