It is a Lacie d2 quadra drive but FreeBSD reports this; server kernel: ad4: 953869MB <Hitachi HDS721010KLA330 GKAOA70M> at = ata2-master SATA150 When I perform the RSYNC I receive these errors Oct 24 12:47:13 server kernel: ad4: FAILURE - device detached Oct 24 12:47:13 server kernel: subdisk4: detached Oct 24 12:47:13 server kernel: ad4: detached Oct 24 12:47:13 server kernel: = g_vfs_done():ad4s1a[WRITE(offset=3D144332767232, length=3D131072)]error = =3D 6 Oct 24 12:47:13 server kernel: = g_vfs_done():ad4s1a[WRITE(offset=3D144332898304, length=3D131072)]error = =3D 6 The write failure messages keep on being issued until the server = reboots. It isn't in the log, but I receive a dirty buffer panic. I don't have easy access to a 7.1 system with an ESATA port. I'm current redoing the entire process, wipe, build filesystem, mount, = rsync using the USB port. If that works I'm going to junk the idea of = using the ESATA card for the drive. Can you recommend an ESATA card that fits in an PCI slot since my server = doesn't have a PCI-E slot?

You've not provided enough information to help track this down. What model/brand of disk is attached to that controller? What does smartctl -a have to say about the disk? What gets printed on the console before it reboots? Do you have the same problem if you run 7.1-PRERELEASE/BETA2? > Does anyone have an idea where to go from here? The only generic advice I can give you at this point) is to avoid Silicon Image controllers, particularly their SATA controllers. They have a history of causing data corruption on Linux, FreeBSD, and Windows, and some have reported other miscellaneous problems with them as well. There's not enough evidence in this thread so far to blame the SiI controller, but when I see them, I become immediately suspicious. --=20 | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
