I wonder if I am alone in experiencing problems with Sata connectors. On at least three occasions I have experienced boot failure because of poor connection to the HDD and yesterday my DVD writer did not function. The DVD is fairly new and so are the cables. The desktop has not been disturbed to cause these problems other than normal insertion of USB devices into front ports. When fully inserted it is possible to wiggle the connector from side to side and it merely takes a judiciuos lateral adjustment to solve the problem. I am minded to insert a wood shaving to assist in holding the connector firm. I must say that, for such an ubiquitous item, one would have heard comments relating to this if this were a common problem. However, considering that my cables and devices have not had undue wear, I feel that the problem can only be an indication of poor design of the connection system.
