Using Hitachi Travelstar 5K1000 in Synology DS409slim

The other day, my Syno DS409slim started beeping. It turned out that two of the Toshiba MK1059GSM disks had SMART errors. I wanted to get some new but they are not available any more. After looking at my preferred e-shop, I finally went for Hitachi Travelstar 5K1000 (HTS541010A9E680). It is not listed in “What hard drive models are supported by Synology products?” page. But it seems to be working fine ; for a bit more than three weeks now.

Here’s a small summary about replacing the disks on Synology DS409slim using DSM 4.2 and SHR volume.

But once there, you’re stuck with a basic shell and a few commands. No `less`, no `grep`, no `bzip2`, no `perl`… Synology provides an official packages repository that provides a few extra features ; like VPN, LDAP and such ; but not so much to get a “complete” UNIX environment. The savior here is called “ipkg”. Quoting Wikipedia: “(…) the Itsy Package Management System (ipkg), is a lightweight package management system designed for embedded devices that resembled Debian’s dpkg. (…)”. It provides a bunch a GNU-like tools and it runs on the Synology!
