I work at a repair shop and I've run into this issue twice already on both Windows 7 (MBR) and Windows 8.1 (UEFI). The problem starts with a customer bringing in the machine after someone remotely hijacked it via a phone call. Usually we reinstall the machine since there is no way to figure out everything that was done to the machine. We do test all hardware (Surface scans, memtest, psu test) to make sure everything is working prior to a reinstall. However, the last two times we have gone ahead with a format and reinstall everything works correctly then after a few reboots the hard drive loses all it's partitions and is unallocated. One of the two times it has happened in the store so there's no way the customer could have installed or done something wrong, the second time the customer did pick it up and had it for two days, which brings uncertainty into the equation. Ultimately we have replaced the hard drives and everything works normally after that.
After for my question, has anyone else experienced an issue like this? If so, what would be the remedy without replacing the drive?
Thanks in advance guys!
