So, this description may be a long one...
First, the HDD info:
Controller Board: 100664987 Rev A
A family member (who is an author) recently had their HDD fail with many chapters of their book stored within the drive. Since I'm a EE, they figured that I should be able to fix it. I made no promises, but took a look at the drive. Here is what I have seen so far.
In Disk Manager, the disk shows up without any space that can be allocated or any volumes. Thus I am unable to assign drive letters and the like. As the subject mentions, when I look at it in the DiskPart utility it only shows up as 6656 Bytes without any partitions. I've used a hex reader to open the disk and it shows the MBR only with a total sector space of 13. Based on the research that I've done and having little to no knowledge about Hard Drives my only guess is that something is wrong with the controller board and the ROM needs to be transferred to a donor board. The HDD does not make any "clicking" sounds and seems to spin up fine. One last detail, I've used Seagates tools and found that it passes some of its SMART tests, but fails some others. I'm not quite sure which ones specifically.
Any help or insight would be greatly appreciated.
