Chain store Dixons featured in a newspaper investigation this week after a freelance computer expert was reportedly 'shocked' to find a computer he bought as an ex-demonstration model held personal details about a psychiatrist's patients. The doctor said Dixons had assured him the computer would be wiped clean after he exchanged it for a new one. The store claimed it had not been told the computer contained confidential information and said customers were responsible for information held on PCs, although it would normally wipe files before selling reconditioned models.
