While looking at an eSATA connected external disk with a medium error, this sense data appeared: READ cdb: 28 00 96 4a 7a d1 00 00 01 00 duration=2816 ms READ: Descriptor format, current; Sense key: Medium Error Additional sense: Unrecovered read error - auto reallocate failed Descriptor type: Information 0x00000000964a7ad1 Raw sense data (in hex): 72 03 11 04 00 00 00 0c 00 0a 80 00 00 00 00 00 96 4a 7a d1 That is pretty close to what I was expecting to see. If anything there is too much information. That "Unrecovered read error - auto reallocate failed" [asc/asq: 11h/04h] should just be "Unrecovered read error" [asc/asq: 11h/0h]. See sat2r09.pdf table 105 or sat3r00.pdf table 105.
If any auto-reallocate occurred on the drive's part, it definitely failed at that point. And auto-reallocate is a possibility.
11h/04h seems to more accurately describe the situation. Jeff -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
