WD 500GB USB3 2.5" SILVER Drive type 2.5-inch external USB hard drive Connector options USB 3.0, USB 2.0 Available capacities 500GB, 750GB, 1TB, 2TB Capacity of test unit 2TB Dimensions (LWH) 5 inches by 3.3 inches by 0.7 inch Weight 0.5 pound OSes supported Windows 2000 or later, Mac OS 10.4 or later Software included WD Utility, WD Security, WD Backup Design and features Judging by how it looks, you wouldn't think that the new My Passport offers the top capacity of the current recording technology. The drive is very compact; in fact it's 0.2 inch shorter than the 1TB version of the WD My Passport Studio. The drive has one Micro-USB 3.0 port and comes with a standard 1.5-foot USB cable, which is used for both power and data. It works with both USB 3.0 and USB 2.0 ports. I tried the drive with multiple computers, and all of the USB ports were able to power the drive. It has rubber feet on the bottom to help it stay put on any surface. There's nothing to setting up the My Passport when used with a Windows computer. The drive is preformatted in NTFS; all you need to do is plug it into a computer and it's ready to be used. If you want to use it with a Mac, you'll need to reformat it into HFS+ before you can write to it. The drive is preloaded with WD Utilities and WD Security for both OS X and Windows. The former is for monitoring the drive's condition, reformatting it, and so on, and with the latter you can turn the drive's security features on or off. Note that once the security feature is turned on, if you forget the password, there's no way you can access the data on it. For Windows, the My Passport also comes with WD Backup, making backing up data a very easy and intuitive job. You can choose to back up folders and files, or it can automatically back up important data, which is very useful for those who aren't as computer-savvy. Unfortunately, the backup software doesn't include a scheduler; however, you can set it to work automatically when the computer is idle. الحالة جديد
