The Disk is too small

#1 Post by Sierrab » 30 Oct 2014, 22:54

Hope that you can help

Background, I had a my C drive crash on Monday, leaving me with only 39gb of files visible in one partition rather than the approx 350 there should be in that partition which should be 500gb or so in size. The disk is 500gb with one partition

Test Disk is reporting that the hard disk was too small plus the message "The following partition can't be recovered"

The files it is reporting are the ones that I can see in Explorer. It is only seeing the 39 gb not the whole disk which is why it is I think it is reporting the disk is too small.

On the other hand windows is reporting that there whole drive is healthy and active and is the correct size

I would be grateful for idiot proof instructions (if there are any available) on how to proceed.

Many, many thanks for entry into the forum

This is ugly. Pleases see the lo and see if there is anything that you could advise.

The drive should contain 350gb of data, but only 30 or so are showing
