The data was written to the tape incorrectly, since reading always gives the same result. The drive didn't notice any write error. My test consisted of tarring up some kernel sources and splitting them in files of 16 MB. Then I archived the files on the tape using tar. Some of the files are corrupted. Each corruption consists of 32 consecutive bytes being changed. The corrupted bytes are not random, but seem to contain parts of the kernel sources. This indicates that some data got copied from somewhere in the buffer cache. The disk with the test files is connected to a MESH SCSI interface. The tape drive is a HP C1536 DDS and is connected to a Sym53c875 SCSI card. The machine is a CHRP LongTrail running the 2.4.3-pre4 kernel for PPC. Anyone who saw something similar?
