I am receiving a sense key medium error in my log each
night when dump runs. I know there is a bad block
marked on the disk.

Does dump honour blocks marked as bad and ignore them?

(I am having trouble figuring out how to translate
sector 2670056 to a block to see if it is the same as
block 333757)

Thank you,
Lauren.

Dump doesn't read all the blocks on a filesystem: for each
inode in the filesystem, it finds out the list of blocks
used by the inode (call to e2fsprogs library function
ext2fs_block_iterate2), then it reads each block
with simple C library lseek/read.

If your filesystem has the knowledge about the bad blocks
(mke2fs + badblocks), dump shouldn't touch these blocks.
