Toshiba MKGAS 30GB-80GB laptop drives, have been reported to emit clicking, grinding and whirring sounds. Our engineers have identified that this is due to poor spin tolerances.
The noise is loud and is a clear warning that the drive has a problem. Users have also caused additional electronic damage, by constantly re-powering the drive, which is a far more serious problem than the first one. If the problem occurs immediately stop the drive and contact DiskEng for advice and data recovery.
