The Keck Center has purchased and made available four rewritable optical drives for use by any member of the Keck Center. Each platter has a formatted capacity of about 500 megabytes per side . These disks are intended to be used for backing up data from experiments, data analysis, presentations, etc.
Users are responsible for the long term backup of their files.
We have run out of the platters which we originally bought and were redistributing on a recharge basis. You will need to purchase platters from a vendor. Be sure to get 1.2 gigabyte platters which have a 512 byte sector size. System backups are performed regularly. However, these are for disaster recovery.
