+Disks in the shelf are listed alphabetically starting from `b`, such that `/dev/sdb` is row 1 column 1 and `/dev/sdh` is row 2 column 3.

+We can get each drive's serial number, power on hours, and manufacture date with the following one-liner:
+
+```
+for dev in {b..y}; \
+  do echo "### /dev/sd$dev" && \
+  smartctl -a /dev/sd$dev | awk '/Serial number:/{serial=$NF} /hours:minutes/{powerontime=$NF} {FS="\n"}/Manufactured in /{manufacture=$NF}END{print serial; print  powerontime; print manufacture; printf "\n"}'; \
+done
+```
+
+Make sure to update this list *only* when a disk is newly installed. Also note the date of installation for the disk.
