Of all the things that can happen during Chinese New Year this week, I accidentally made the data on my network attached storage (NAS) device unreadable – and could easily have wiped out all the years of reports, financial statements and holiday pictures I’ve stored on those two 1TB drives.

After days of pulling hair out, I eventually salvaged everything. But the entire episode prompted me to ask if I was really as prepared as I thought if I had accidentally deleted my data or, in this case, plugged my drives into a new NAS without backing things up.

The answer lies in a series of software tools you can use at home, before really going to the pros in data recovery for help. Here are a few that I tried out while panicking through my attempt at rescuing my data.

Before we start, let’s remember to always back up important data, like your wedding day photos or your personal financial records.

A note to all small business owners like me – RAID – or mirroring your data on multiple hard drives on your NAS is not backup. You have to have more than one copy of your data on another DEVICE, not just another drive. That means even if your NAS dies, you have a portable drive somewhere with an up-to-date copy of the data.

Looking back, I don’t know what possessed me to plug two 1TB drives from an old QNap TS-209 II NAS into a new QNap TS-419P+ NAS. Perhaps it had to do with the retailer at the store confidently telling me that sure, I can just plug in the drives and they’d be recognised by another QNap NAS. Or perhaps I was overly confident about QNap.

Either way, I ended up with two 1TB drives that could not be recognised by the new NAS or the old one, when I tried plugging them back in. Not even with QNap’s Live CD, which boots up your PC with the company’s version of Linux, or when I plugged a drive into a Windows PC supporting the Linux EXT2/EXT3 file system, could I try to extract the data on the disks, which had not been formatted.

The reason: the disks had been re-partitioned by the new NAS during setup and the partition information for the portion of the disk containing the data could not be read by almost any other device.

1. iCare Recovery
The first tool I used, fearing the worst that the data on my drive cannot be read again, was iCare Recovery and the plan was to go “nuclear”. Heck, just read me the sectors on the drive and see what you can recover. That’s what this tool, iCare Recovery, does quite well in.

Like with other such demo versions, I could see some of my files with a test and I was super elated to be able to save a couple of them at least. I bought the software digitally for US$62.95 in my haste. Hey, having some data back is better than none. At this time, I had given up hope of folks from QNap replying (it was during Chinese New Year earlier this week, but they still haven’t replied today at the time of writing) or from help from its online forum.

So I went ahead and scanned one of the drives with iCare Recovery. It found loads of stuff, really too much in the end. These included long-ago deleted files when one of the drives was used in another computer. Now, that should tell you how scary things are – “delete” and “format” don’t really wipe data, not all of it anyway.

The main problem, though, was that iCare worked more or less in the assumption that this was a last gasp solution. It sorted things out according to the type of files it thinks the bits and bytes are. So, you get thousands of files, all renamed to something unrecognisable and ordered as, say, JPEG files or PDF documents.

At least with pictures, I could still run them in thumbnails, but I had to recognise ALL the hundreds of thousands of files individually. Worse, I had to open some of the files, like PDFs, to see what they were first. I gave up after an evening doing this. Getting a whole load of data in a mess was just slightly better than no data at all.

2. R-Studio
I looked to R-Studio, another application which took an even more detailed look at the hard disk and could return everything in the right directories with the right filenames.

I was suffering from tonsillitis during this time, and you can imagine, even with that, my mood lifted knowing I could get at least most of my data back. I clicked on the “buy” button immediately when I found that I could recover several files – like my yearly statements to the tax man – with R-Studio.

The bad news about R-Studio was that it took a lot of system memory to do the job. It would take my quad-core i7 CPU three hours to scan one disk, but worse, it would crash for lack of memory when trying to enumerate and list the many thousands of files in the drive. I stuck a spare 4GB RAM module into my existing 6GB machine to make 10GB but I still had problems showing all the files I wanted to recover.

It was frustrating being so close yet so far. The software would stop and do nothing for half an hour if I tried to list more than, say, 40 per cent of the files. It had detected an astonishing “17TB” of data – most of it including repetitive entries – from a 1TB drive and was trying to load that data in the PC’s memory because it doesn’t want to write to any of the disks to prevent more damage.

The downside: my machine was too slow to run R-Studio. Stopping the file listing halfway, I could get back perhaps 70- 80 per cent of the data but I was not sure they were the latest versions (several versions could have been detected when I stopped the process).

TestDisk
Finally, more in hope than expectation, I downloaded TestDisk, an excellent open-source recovery tool (free!) after reading the experiences of fellow QNap users in the forum. I hadn’t expected much from a small 3.3MB application after supposedly more sophisticated tools had not been the answer.

To my surprise, TestDisk even has a “GUI” that lets you avoid typing in commands by moving through the options available on a menu with your keyboard. It’s easy to use and guess what, it managed to find the lost partition on the disk “troubled” by the QNAp installation procedure.

This meant I could mount the drive and read the partition containing my data files and select them to be copied elsewhere. All I had to do was simply select the folders which I wanted to back up to an external drive and that’s all, 100 per cent of my data could be returned to what it was.

The only advice I’d have here is to hide the deleted files – otherwise you’d also copy over deleted files that include the annoying temporarily files that Microsoft Office generates when you have an open Word document, for example.

I’m just so glad that I managed to get the data out of the corrupted disks. Indeed, I learnt that there are many ways to get your data back. Unfortunately, instead of trying the least desperate measure, I panicked and went straight for the nuclear option and ended up spending unnecessary dollars.

Still, this somewhat illuminating episode also shows that you can sometimes save the data on your own drives, before deciding to send them to third-party companies. Okay, not everyone has Edison Chen-type photos but hey, it’s always better if you can solve things yourself, say, when you need the data over a long holiday, for example.

One of the questions I often get from friends coming up to Hong Kong is if stuff is cheaper here or in Singapore. In many cases, the answer is “not really” or “just a little” – but in the case of the Synology DS210j that I bought for my bro recently, it was a helluva lot cheaper!

At HK$1530 (which is about S$278 at 1S$:5.5HK$), you’d be paying almost 50% more if you bought one from Synology’s dealer in Singapore (Memory World) which has priced it at S$408. Plus according to the Synology forum (post dates back to 2007 though), Synology does provide international warranty.

So why the DS210j? Only the Qnap TS210J II comes close to the DS210j’s transfer rates, but is more expensive. The rest of the 2-bay NAS competition, like the D-Link DNS-323 are generally slower. Oh, and its DLNA compliant too, so fits in with the plan of adding those ‘media extender’ devices to stream video and audio later.

And so far, the DS210j – paired with 2 x 1TB Seagate ST31000528AS HDD – has proven to be a great buy. No nasty surprises – it runs quietly, was easy to hook up to the network and does what it’s supposed to do.

The installation process could have been a tad better documented though. During the initial install, the installation wizard asked for the latest firmware file to flash the NAS, which left me for a sec wondering where to find it. After digging through the install disc, it turns out that the firmware files were in a directory labelled “patches”. In any case, geeks need to stay on top of firmware revisions so I went on down to their website and found a version that was newer than that on the disc.

Mac users will also be happy to know that the NAS popped right up in the Finder (I’m on OSX10.5.8) – leaving nothing to muck around with.

So unless you want to venture the DIY NAS on FreeNAS route that Alfred had shown previously, the Synology DS210j is the best bang for buck in the RAID 1, 2-bay NAS scene – especially if you get it here in HK!

Even for the most hardcore users, you’d think that the ultimate router is one that has a gigabit WAN port and an OLED screen like D-Link’s Xtreme N Duo DIR-855.

Well, the company has just topped that by coming up with a router that also acts as a digital photo frame, as well as a network attached storage (NAS) device. Bar the kitchen sink, the new Xtreme N DIR-685 probably has almost all the features in a consumer router.

D-Link Singapore has just said that the S$399 “desktop-design” router will debut at the Comex computer show here next month.

So, what do you get for that sky-high price?

The Wireless N router will come with a 3.2-inch LCD screen that streams pictures as well as information such as weather and financial news from the free FrameChannel service. Of course, you can also show off gauges like download speeds on screen, if you are the type who needs to know how fast your torrents are downloading without firing up your PC.

Is the screen really a big plus? Well, no, unless you place your router in the living room or somewhere in the apartment where the photo frame would be a nice touch. I just can’t be bothered looking at the small router screen if I am sitting in front of a 24-inch PC screen (trust me, I have a DIR-855).

More attractive is the DIR-685′s  full-featured network attached storage (NAS), which lets you snap on a 2.5-inch SATA hard drive by the side for quick sharing among computers in the network.

Surprisingly, the NAS functions include ones you’d find in full-featured NAS boxes. You get FTP to share your files with friends over the Net, a BitTorrent client to download directly to disk (so you don’t have to keep your PC powered on), as well as a UPnP server for streaming your videos to networked PCs or game consoles.

Not a bad number of features, I must say. So, this combo will surely attract those who want a NAS, but are worried about setting stuff up. In this case, D-Link user-friendly menus should help get you up to speed in no time.

If you have use for all these features, okay, then S$399 might seem fair.

But don’t forget that you can get the components separately – a Wireless N router (S$100), photo frame (S$60) and a NAS (S$200) – for slightly less (S$360). And unlike with the DIR-685, you don’t have to worry about them all breaking down at the same time.
