PogoPlug Cheap NAS

I wrote previously about http://blog.thegiblins.com/2012/07/pogoplug-cheap-deal-and-hack.html , a good deal from Pogoplug.

I was really intersted in that there was a Sata port on the inside and it had a Gigabit Ethernet port.

I explored the options available to connect and power a sata drive. I eventually found a "NEON SSD/HDD Stand-alone Duplicator and Docking Station (USB2.0 - eSATA)" on MemoryC.com. Just under €32 and free shipping. What could possibly go wrong? It turns out to be a fairly good product, with USB and eSata ports plus external power. Fits 2.5 and 3.5 inch drives.

OK, so crack open the PogoPlug, easy. 

Warning: The power board is on the right of the picture. It has exposed 220V and this can kill. Be afraid. Be very afraid, and careful.

I ordered a Sata to eSata cable from eBay. I am probably going to have to drill a hole in the side of the case to allow the cable to fit properly and exit the case.

I plugged in the Sata side of the cable into the PogoPlug Sata port.

 Connected the eSata side of the cable to the Docking Station. I had an old 80Gb drive that I used for testing. Power the Docking Station on and then the PogoPlug.

 The happy marrige, PogoPlug meets Docking Station.

When I first turned it all on, it wouldn't boot. Feck I thought. Dr Google was no help.

I thought about it for a while and I thought that perhaps the Sata drives were being initialised first, becoming /dev/sda1. The system was configured to boot from a USB stick as /dev/sda1.

Test 1: Set-up to boot from Hard Disk /dev/sda1

I plugged the USB stick and Docking Station into my trusty Linux Laptop, identified the devices, which were /dev/sdb = Docking Station and /dev/sdc which was the USB drive.

I ran:

[root@wideboy ~]# dd bs=1M if=/dev/sdc of=/dev/sdb
7498+1 records in
7498+1 records out
7862353920 bytes (7.9 GB) copied, 506.336 s, 15.5 MB/s

Cool so far. I plugged out the Docking Station and back in again.

I then ran 'fdisk -l' and got

[snip]

So, I had an 80Gb disk with a tinchy partition. 

Time to crank up fdisk again.

[root@wideboy ~]# fdisk /dev/sdb

All good again.

I then mounted the partitions to check that everything looked OK. It did.

I then connected the Docking Station to the PogoPlug and powered everything on.

Note: the PogoPlug does not have the USB drive attached.

Low and behold, everything booted. The PogoPlug was booting from the eSata attached hard disk. Woo Hoo! Better then I had originally expected.

Test 2: Crack open a cold brew and blow the froth of it

Kick back and watch you favourite movie. You earned it

Love Linux. Love Arch Linux. Love Arch Linux Arm.

Low power computing. Save the world.

What will I use it for? I am going to try OwnCloud and see if it can run in 128Mb of ram. At least I should be able to run Samba and NFS on it.

PogoPlug Cheap Deal and Hack

I recently signed up for a PogoPlug Family Backup Offer . It cost €24 in total.

The best thing is that you get a free PogoPlug Pro.

Being a big embedded Linux fan, I was eager to find out if this was one of the hackable devices. It was a cheap price to pay, to find out if it was useful.

It arrived on Friday. The first thing I dis was to crack it open. That was even before I powered it up. I am that sort of guy.

It turns out that it is Model: PogoPlug Pro FCC ID: VUIPOGOPLUG. The one with the Grey/White Symbol on the front. It turns out that it is a hackable device, see Link.

I wanted the smallest USB drive I could get. I went to Power City and got an 8GB drive by someone or other. Picture here:

So, I horsed over to http://archlinuxarm.org/platforms/armv6/pogoplug-provideov3 and followed the recipe to install Arch Linux on the device. It worked like a charm.

Another Arch Linux box joins the Empire.



It has some wireless card and a SATA port and of course a Gigibit Ethernet port. Ultra cool to build some sort of data/file server or anything really.

I think I will investigate the possibility of connecting an SATA drive to it and use for centralized MyDocuments and Photographs.

Only the Windows client can take advantage of independent storage on the PogoPlug cloud. I may incorporate that into a general offloading plan. We will see.

The best thing is 'Cheap PlugComputer' and benefits that could be used.

Win. Win. Win.
