I need to back up some files because if my computer crashes I lose all of my Family History that I have spent hours and pounds researching. I have been told to get an external hard drive but know nothing about them. What does buffer size mean? I have found one 500GB which is big enough memory but are they easy to use? Please help !
Oh yes, they are really easy. Just plug it in and look for it on "my computer", then copy and paste and files you wish to store on it just like you would do with a USB stick.
Yes, extremely easy. I've got one, 250gb, which is huge. Plug it into a USB slot and it just appears in Windows Explorer, e.g. as a G: drive. I think I paid about �60 in PC World. You get a thingy in your tray (bottom right) to eject it properly when you are done. A very good idea indeed, many people forget to back up.
p.s. don't get embroigled into debates about how fast it is, transer rates, that sort of thing. For backups you don't really care. I right-click-copy and paste whole folders onto my USB drive and watch tv while it gets on with it. Whether it takes 3 minutes or 30 is not important.
Most programmes require a "set up" file. You should back this up or ensure you have the original software. Just use the external disc to back up your family tree data.
Many games and applications install into the Program Files folder. With an external hard drive, just right-click-copy your entire Program Files folder to the new drive and make a cup of tea while it is copying it. With the inherent reliability of modern hard drives (I have never had a drive failure) you are unlikely to need it, but there are other reasons, e.g. accidental deletion, why having a backup is such a very good idea.
