Yes, that will work as long as you run it as root, but if it's that old, you might have a bad sector or two.
At a minimum use this:
dd if=/dev/sdb of=[whatever] bs=512 conv=noerror,sync
bs=512 will slow things down, but make sure that if you have an error, only the truly bad sectors will be lost. A sector is 512 bytes and they are either good or bad.
noerror says not to stop just because you hit a failed sector
sync says that if you have a bad sector, fill that part of your backup with zeros.
Any reason not to use dd_rescue instead of dd in the first place? -- "The wise are known for their understanding, and pleasant words are persuasive."
