data from those PCs as they are now and give enough extra space for what you might accumulate in the future. Then, consider what you stand to lose when and not if that big drive fails. As for overwriting previous data, that only happens if you copy new files with the same names as existing files in folders on the drive and you will be asked first. Files aren't removed in rollover fashion as the disk fills.
I am in the market for an EHD. I think I want a 1.5 TB or 2 TB. My ? is will we be able to store several PC's files on one Drive? Or will it write over what is put on previously?
I was thinking big because I am hoping we can store info for our 5 PC's.
Thanks in advance
