Seagate backup plus portable 1tb external hard disk is a good memory storge device to carry on. I bought it recently and it has been working quite smoothly. Though I feel there is a serious issue with seagate. Although they provide impeccable post sale services but the hard disks are very fragile. I used to keep the device in soft padding of my laptop bag still due to some jerks here and there it got damaged somehow and stopped working. This physical aspect of being damage prone is too much of a problem rest everything is okay with the portable device.
