      I am a huge fan of this hard drive and currently it is serving as Time Machine backup for my Mac OS X. Once it had corruption which needs to be repaired asap so I tried Stellar Volume Repair. My drive was suffering from Invalid B Tree Node error which Disk Utility refused to fix. Fortunalty, this software is efficient enough and repaired it within few minutes. Try for free -
