Seagate série 7200.11a

Recently we have seen increased numbers of Seagate 7200.11 hard drives failures. This problem usually appear on drives with capacity between 500GB and 1TB with part number ST3500320A, ST3500320AS, ST31000340AS. Drives Seagate 7200.11 use new firmware which completely change way how it works with defective parts of partition table. Main reason for this problem is buffer underun which leads to wrong inscription to error tables. Theses drive than show in operating system non-sense size usually 0MB or these drives are not detected at all (usually that’s sign of electronic parts failure). For this reason recovery of data from these model was extremely hard and usually not even possible. Our company Microshop S.A R.L developed procedure with which we are able to recover data in 90 percent cases.
