A:AnswerIf you are asking about replacing internal TiVo Bolt 1TB drive by removing the external’s hard drive, then yes and no...the Bolt has a 2.5”, and this external has a 3.5”, Hard Drive. So, if you don’t mind potentially having the hard drive and cables sitting outside the Bolt, yes it will work. If you are wanting to backup your Bolt, or add additional storage, it may work after reformatting the external hard drive, but again, I’d buy a Toshiba external hard drive with as much storage capacity as you can afford; Toshiba’s have had the best results with Bolts.
A:AnswerYou could use drive imaging software (which gives you a file you can use to reinstall) or drive cloning software (which make a second drive a duplicate of the first drive). Many of the drive image programs provide you with a program that allows you to browse the image to see what is there. If you are cloning the drive, remove the original drive, and boot from the clone drive and you will see that everything is there.
