SSD Series 320 problem forced Intel company to exchange defective copies and start preparing a revised firmware which would prevent a sudden loss of data and volume. As a temporary way to recover the drive the owners use the procedure proposed to guarantee the removal of data by Intel Toolbox utility. Data lost recover in this case was not possible.
According to the statements of Intel representatives, the updated firmware for 320 series solid state drives will be released in two weeks. Note after update the lost data will not return.
