I had a power cut and my computer went off. After the power came back on my external hard drive does not show up in my computer. It says it needs to be initialised. It also shows up as unknown and not initialised in computer management. It does not allow data recovery software to read the drive at all. I am worried that if I initialise the drive I will lose all the data that is on it. I have enclosed 3 pictures that show what I am explaining. I wondered if this could be a PCB or hardware issue causing this also ?. If I try to initialise the drive or put it as offline if fails and says IO error. Any help would be greatly appreciated ?. I could not upload the pictures as they are too big in size so have added some links below.
