Hello, I'm trying to use dd to duplicate a hard drive. I have two identical Western Digital 2.5 gig drives, even the same model number. I used dd if=/dev/rwd0 of=/dev/rwd1 to do the duplication, as per various archived postings. However, when I try to boot off the disk, I get a warning like: /dev/rwd0s1f: /dev/rwd0s1f: BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH FIRST ALTERNATE Then the oh-so-familiar "run fsck, press enter for sh". I run fsck, and get a floating point exception. fsck exits on signal 8, with the same warning as above. Any thoughts on how to fix this? (The eventual goal is to create a single master hard drive that we can use to quickly reproduce servers for customers: any other suggestions on how to accomplish this would be greatly appreciated.)
