Hi Guys,

First post here so apologies if its not in the right place or to the correct standard.

I (foolishly) agreed to help fix a friends computer. He had done a windows update and was stuck in recovery loop after, tried booting to Win8 live usb but eventually realised the HDD had to be removed for further tests. The laptop is a samsung chronos 7.

I am now at the stage of attempting to image the drive using FTK imager.

In crystal disk info its report a health status of bad. The image is attached.

Basically what im wondering is am i doing anything wrong? The imaging has been going for 9 hours so far, with a compression ratio of 6. His user area is ~100gb. So far the image files are 1,536,000 kb (split point) and 772,928 kb.

The questions I am wondering are:
Is there any hope for recovering the files? (they are viewable in explorer, but is very slow)

What size would you extimate the total final image size is so i can estimate how close it is to finished?

And how worrying are the errors crystal disk info reports?

Sorry for the crazy rambling post, but I am really regretting taking on this job as it was probably more suitable for a professional data recovery specialist, and I am quite fearful for the outcome.

Any advice would be massively appreciated, thanks for reading.

PS I understand that if data is written to a bad sector it is likely gone or corrupt, I am mainly interested in the good sector data. Also please correct me if anything i have said is wrong.
Cheers

I don't know much about FTK Imager, but I suspect that it is bogging down on bad sectors. You might like to ask the professionals at the HDD Guru forum if there are options to speed it up.

A freeware alternative is ddrescue. It understands how to work around bad sectors. Ddrescue recovers the easy sectors on the first pass and then tries for the more difficult ones on subsequent passes. It also keeps a log so that it can resume after an interruption.

Awesome mate, thank you for your response. I am going to start that ddrescue image right now as When i came downstairs this morning, my pc was showing the desktop and had done a restart at some point during the imaging process (bloody windows update). And yes I might check the hdd guru forum also, thanks again.
