Until they are written over. If you delete 5 files, for example, they will stay on your computer until the space that the files added to your drive is taken up again. Then the files will be permanently gone.
as long as theres enough room on the smaller hard drive...then yes..
Yes, as long the hard disk drive is not NTFS formatted.
a long time its hard to drive alot
depends on the type of drive, but as long as the drive is kept away from magnets and at the proper temperature and humidity it should last a decade or two.
Yes. Operating systems can read any hard drive (as long as the drive is not corrupt)
To recover data from a RAW hard drive the hard drive must be intact in some way. Connect the damaged hard drive as the slave drive and another hard drive that is in working order as the master drive. This should allow for file transfer as long as the RAW drive is not too far damaged.
An analogy for the hard drive in a human body is the brain's ability to remember things over the long term and the ability to remember them at any moment in time, a bit like uploading them from storage to RAM, so that you are thinking of them.
Yes as long as the hard drive has its own power supply and not powered by the USB port.
hard disk drive
Well it can vary between high speed SATA or high speed IDE hard drives. They all link into a port on the side or middle of a motherboard. an IDE hard drive is a hard drive with a long rectangular outlet or hookup to the motherboard. A SATA hard drive is a small but reliable plug to the motherboard about half an inch long.
No it does not. As long as the motherboard has the proper connectors for the hard drive you are installing, IDE or SATA, you will not have to replace it. If the connectors are different, then return the hard drive and get one with the proper connection type.
Restoring files on a hard drive can always be done as long as the hard drive itself isn't irrepairably damaged physically. If you are able to replace that hard drive with the hard drive in another computer and boot it up, you should be able to roll back the hard drive to a different restore point where everything was accessable.
