Ur-Disk 128MB Mini USB HDD



Floppy drives are now a thing of the past or at least should be, but we still need to transfer data don’t we? CDR media is a popular alternative to floppy drives because it can hold a lot of data, and with CD burners being so fast now a days only takes minutes to burn a CD. The problem with CDRs is that you only get to use them once and cannot modify data, even if you are using CDRWs it will take a good ammount of time to do add or delete what you want, not to mention that the computer will have to have a burner and software installed. So what is there to do? You could use a Zip drive, JAZ drive, or carry around an entire hard drive but all of those options have their downfalls. There is a really cool way to solve all your problems, use a mini USB hard drive, the great thing about this device is because it’s USB no drivers are needed. You can use it on any computer, its small, and it’s fast. You can read, write, copy, delete and move data from your hard disk drive to the Ur-Disk or from the Ur-Disk to your hard disk drive. This little drive has a lot to offer, more than you would expect from something this small, but then again does size really matter? This little hard drive can transfer up to 12Mbit per second at “Full Speed” and is supports power saving mode to reduce the power consumption while using Ur-Disk in any mobile devices. Ur-Disk is supported on Windows 95 OSR2 with USB support, Windows 98, Windows 98SE with a device driver and with Windows ME, 2000, XP, Linux, Mac 9.0 or above without any device driver. The Ur-Disk also has a green power LED when the drive is plugged in and an amber one flashes when it is transferring data. Because the Ur-Disk is powered by USB bus (4.5V ~ 5.5V) you don’t need any external power which means you can install it anywhere.

I opened up the box to find the black Ur-Disk and it was a lot smaller than I thought it would be but that is a good thing. The Ur-Disk is on the top of the box and all of the accessories that you get are below it. Along with the Ur-Disk you also get a CD, USB extension cable, neck strap and 2 little labels.

The Ur-Disk is very small, I put it next to a 3g tube of Arctic Silver 3 so that you could get a good idea of how small this thing really is. As you can see its basically about the same length while being much thinner and lighter. The Ur-Disk comes with a USB extension cable so that if you don’t have front USB ports you don’t have to crawl around to the back of your computer. If you don’t have front USB ports I would suggest you do the front USB mod guide that I wrote because it will make using USB much easier. The CD that comes with the Ur-Disk contains drivers incase your operating system doesn’t support it and a format utility so that you can format the drive if you don’t want to use Windows Explorer. You also get a neck strap which can be attached to the Ur-Disk and you can wear it around, I don’t know if you really want to do this but you can.
