28 If no disks are attached, I wonder if something is probing it?

30 I checked my dmesg and every time I plug in my eSATA enclosure, I see
31 this very similar message:
32
33 [156541.724580] ata7: exception Emask 0x10 SAct 0x0 SErr 0x4040000
34 action 0xe frozen
35 [156541.724587] ata7: irq_stat 0x00000040, connection status changed
36 [156541.724593] ata7: SError: { CommWake DevExch }
37 [156541.724604] ata7: hard resetting link
38 [156551.725559] ata7: softreset failed (device not ready)
39 [156551.725567] ata7: hard resetting link
40
41 (and then a bunch of lines initializing all of the disks in the enclosure).
