Re: Q: recommendation for external USB disk
Hi, just buy the hard disk of your choice and put it into the case of your choice. I use only disks which come with five years warrenty.

Your /dev/da1s1d let me think that you have created more than one partition... After a bad experience, I use as many slices as the machine uses I take the data from. I also backup the programs. Then, I use for the external disk the same interface which I can use in the machine. So, if the internal hard disk fails, will be able to exchange the disks and boot. Ok, fstab might needs to be edited.

Q: recommendation for external USB disk
Hello, Can someone recommend a good external USB disk for backups which works with FreeBSD 8.0 and has more than 512 GByte?

Thx in advance Pretty much anything that you consider to be a reliable supplier will do. There are no specific FreeBSD requirements as far as I know. I recommend that you get a disk that is externally powered instead of with power supplied over USB. Earlier versions of FreeBSD had problems with USB connected devices. In particular if they were removed or powered down without dismounting, this could lead to a kernel panic. This problem has been fixed, but I still am extra careful with my USB backup disks: (1) Power for the back-up disks should be on a UPS (2) umount the file systems on the back-up disk when not in use.
