Controller Error

A Controller Error, most commonly seen as "driver detected a controller error on \Device\Harddisk1\" (or another Hard Disk number, if appropriate), can be a number of things. This is typically a go to error, very common in Windows XP and above. There are a few simple potential fixes:

1. Replace your IDE/SATA Cable - particularly common on older cables is kinking of the cables, which can prevent full throughput, and cause errors.

2. Unplug and then re-plug-in your IDE/SATA Cable - sounds simple, but sometimes the simplest fixes are the most effective. Cables that are not fully or incorrectly plugged in can cause errors, including the "Controller Error"

3. Ensure Your Jumper Is Placed Correctly On Old Drives - This is mainly an issue for older, IDE drives, but it is possible in some cases that your drive's jumper is incorrectly placed. With typical hard drives, there are three positions for a jumper: Master, Slave and the most commonly used, Cable Select. Is your jumper in the correct position?

These are simple potential fixes, and are not always effective. In cases where your hard disk drive has failed mechanically, these fixes will not be effective.

When a hard drive or RAID array has controller issues that are mechanical, it is always best to contact a professional BEFORE you attempt any serious "do it yourself" Controller Error fixes. Get in touch with a professional data recovery technician here.
