The disc was sent on the 9th of June to MIS Emergency Services Ltd in Manchester which is responsible for dealing with the IT system used by the Scottish Ambulance Service but it was reported to the Scottish government only 10 days later.
The portable disk was lost by a TNT courier in transit and included the names of patients, addresses of incidents and phone numbers; the files however are understood to be encrypted and password protected, which will make it very difficult for criminals to access them.
Moreover, because they do not contain any bank details, they have very little commercial value especially since some of the data can be mined from public domain data (directories or census).
Still, this is the second time in a month that a disc containing sensitive information is lost by the Scottish Ambulance Service.
