The Reviews don't sound good, 1 x 1 star, 1 x 3 star and 1 x 5 star:

1 star:
I bought a Toshiba 1TB Canvio 3.0 Simple from OfficeWorks about 3 weeks ago. I will be returning it for a refund - the product does not work as promised or as it should.
The product looks great on paper but has serious technical flaw - namely the portable HDD does not stay connected to the PC for 2 possible reasons I know:
1. The default power-saving mode turns off the portable HDD without user permission. Worse, you cannot disable the power-saving mode. So when the portable HDD "switches off", it is disconnected from your PC. As far as your PC is concerned, the portable HDD does not exist anymore. In my case, my Windows 7 crashes on boot-up because of Error: 0xc000000e9
Status: An unexpected I/O error has occurred
Basically, Windows 7 is complaining that a USB-connected device has been removed while in operation, and thus the boot record is damaged. I tried to repair and restore. It worked the first time. Then on subsequent PC boot-ups, I get the message of death (Error: 0xc000000e9) and restore no longer works.

I spent the last week reinstalling/updating Windows 7 and every software that I use. It is an excruciating and frustrating experience!
To give the portable HDD a benefit of doubt, I plugged it in after a fresh OS and software installation. The message of death (Error: 0xc000000e9) came back on boot-up. I took the portable HDD out and rebooted again. Everything is back to normal. No more message of death.
Sorry, Toshiba 1TB Canvio, you are not allowed to go anywhere near my PC anymore.
2. If you google "Toshiba Canvio Problems", you will realise there are truckloads of people having disconnection problem because the USB cable does not stay securely connected to the device or PC. So again, you cannot read or transfer file when you want to. Data corruption becomes a serious risk.
If the purpose of having a portable HDD is to safely store your valuable data (photos, videos, files etc.), then the Toshiba Canvio portable HDD has failed spectacularly.
Sorry, no more Toshiba portable HDDs for me.

3 star:
Connected immediately first time and quite fast uploading. Small, compact, simple to use. However, when trying to use it again a couple of hours later it would not connect. Tried about 10 times but would not connect again. Researched some review sites and technical blogs and found that this item has dozens of instances of this problem occurring apparently due to a 'wobbly' connector. Finally got it to connect again. Seems to perform well, but if you're impatient with tech issues, I'd avoid this one.
5 Star review:
This is the product for anyone who does not know how to preserve their pictures and documents (etc) & for those who don't want to know how or who will just forget to back up until the hard drive fails! Very minor user involvement required and files are very easily managed when needed. I have been looking for this type of thing for my clients who are not so good at manually backing up. There are several brands of drive offering auto backup, Clickfree is the original and still a good option.
