A customer reports that recently several files cannot be accessed. The service technician decides to check the hard disk status and the file system structure. The technician asks the customer if a backup has been performed on the disk and the customer replies that the backup was done a week ago to a different logical partition on the disk. What should the technician do before performing diagnostic procedures on the disk? Run the CHKDSK utility. Perform file restore from the existing backup copy at the logical partition. Back up the user data to a removable drive. "Install a new hard disk as the primary disk, then make the current disk a slave."

USB Flash drives contain thumbnails that link you via a USB port to your device. The size is normally between 128 MB and 1 GB for a Flash drive. The larger drives will be able to hold enough data to back up a lot (more than just a CD whether the Flash drive is 1 GB).

If you want to save info, however, exceeds the drive's cap, you have to use an alternative external media medium like a CD.

Flash drives are usable without any advanced tools and used for data-only backups. Attach the disk to your machine and copy the archive file to the disk. The drive is plug-and-play with all modern operating systems on Windows, Mac, and Linux.
