If you are sure that you had the reiserfs on this partition, then the start of the partition might be changed or all data were wiped out. The start of the partition may get changed by a partitioner if you have used one. Then you probably rebuilt the superblock as there was no one. Zero the block at 64K offset from the start of the partition (a new super block you have just built) and try to move the start of the partition a few cylinders aside and check if debugreiserfs /dev/xxx detects a reiserfs super block. If it does this is likely to be the right super block version.
