I like to read all the way to the OS, and my way works on USB, but your suggested test can be faster and it's nice to get the stats recorded. > mp@: What's surprising is, apart from that `Current pending sector' > count--which hasn't dropped below the threshold (none of the current > values have), how pristine the drive looks.

The drive reports at about 3-4 years of power on hours. fair to check cables, but that usually shows up as ata timeouts or checksum, not uncorrectable read. > 9 74 0 no online positive Power-on hours count 83567178701327 wow, that's a lot! I find drives from 15 years ago (say at 400G capacity) to me more reliable than newer drives.
