Translations:Omgaan met digitale dragers in je archief/6/en

• Estimate what storage capacity you need by grouping the carriers together per type and multiplying the number of copies you have by the capacity required for each type.
• Use a computer that you regularly scan for viruses and only use for this work.
• Create a disk image of each digital carrier.
• Document the folder structure and file information for all digital carriers (filename, size and date of modification). You can use DROID for this. Keep this documentation together with your archive and collections.
• Create and keep a checksum for each file. A checksum is a control figure calculated on the basis of the file contents. (See also Checksums as a way to monitor the integrity of files.) You can also use DROID for this. One checksum is enough for a disk image.
• Create a readme.txt file which documents all the above steps. Save this file in your digital archive.
• Copy your entire digital archive to a secure storage system.
• Clearly indicate on the original carriers that their contents have been transferred.
