Seagate ST3750630AS Data Recovery
Zero Alpha Data Recovery provides professional data recovery services for the Seagate ST3750630AS, a 750GB enterprise-grade SATA hard drive from the Barracuda ES and 7200.11 family. These drives commonly suffer from clicking or beeping sounds (head failure), failure to spin up, not being detected in BIOS, and the well-known BSY or LBA0 firmware bug seen on certain SD15 firmware revisions. PCB issues such as burnt TVS diodes from power surges are also frequent on this model. We recover data from these drives every week and accept mail-in jobs Australia-wide and internationally.
