PCB failures (Such as Toshiba PCB G3448A) affect thousands of hard drives every year and often result in permanent data loss. A hard drive may suddenly fail to power on, and a computer may not detect that it is plugged in. Some failed hard drives will also show up in computer BIOS with incorrect brand/model information. PCB failures can also cause physical issues such as read/write head failures, and many PCB failure symptoms overlap with the symptoms of other physical hard drive issues.

Some emails from customers of Toshiba PCB G3448A failures are listed below, along with tips for replacing & repairing.
