Recovery stalling - Need Help

Hi,

I am quite new to this recovery stuff so please go easy...I'm in need of some direction in order to continue rescuing my data. Sorry for the long post, I have numbered the questions throughout to help with potential response.

Not long ago, I had a mishap with an external Seagate drive that contained essentially all my family photos and videos. The drive hit the carpeted floor from about 18" while it was spinning. Apparently that was enough to do it in. With the assumption that the heads were damaged and after pricing out data recovery services involving internal hardware repair, I decided I couldn't afford to go that route. So I went the DIY route.

After removing the drive from it's enclosure and obtaining the pertinent info off the drive label, I sourced a donor on eBay and went to work. After performing a head stack swap in a hepa clean air environment, I proceeded with using GNU ddrescue via System Rescue CD. So far I have been able to get to approximately 40% rescued according to to ddrescue. Though, I seem to be hitting a bit of a road block. After starting ddrescue, it will run for an arbitrary length of time before the 'current rate' drops to zero. I can get things going again by using Ctrl-C and disconnecting and reconnecting the source drive SATA cable, then checking with probe simple to make sure the disk label didn't change, and finally restarting the process.

Sometimes I can get through a few hours of success before this happens, sometimes only minutes. From reading around on different forums, it seems there is no command to power cycle the source drive on the software side of things. Short of sitting at my desk and power cycling this thing for the next month, I don't know what to do about this.

1. Does anyone have any suggestions on how I might mitigate this issue?

Another thing is this...there is only one folder that I really have any interest in rescuing. Before attempting the rescue I mounted the drive to test it for a moment and found that I could view the folder structure and I could see the folder I need. (Photos and Videos)

2. Is there a way to only focus on this section of the disk during the operation?

After making it this far I also realized that I should have potentially been using the disk labels to do the recovery as opposed to the device label (individual partitions). Although, I think I may be okay so far? As I have been reading a partition and writing to a partition.

3. Will I need to rescue the first partition also? Or is that unnecessary?

I have seen that there is a firmware section on this site. This isn't something I have really looked into, as I attempted to source a donor drive that is as close to the original drive as possible. Paying close attention to the variables in the firmware numbers, serial numbers, site codes, heads map, etc...

4. Is it possible to flash a firmware that would allow for better compatibility between the original drive and the replacement heads?

5. Lastly, once I have recovered as much data as I think I will be able to obtain. Is it okay to view the contents of the new disk on a Windows OS? After viewing, can I continue a rescue attempt? Basically, what is the safest way to view the progress I have made with out messing up the ability to continue recovery?

Any information is much appreciated. I have made it this far and would hate to fail at this point.

Thank you.

You dropped the drive, resulting in physical damage to the heads/surface. You are lucky that it is reading at all. If the data is of value to you, send it to a data recovery professional before it degrades to the point of being unrecoverable. If the data isn't worth, even a few hundred bucks, keep banging away with ddrescue.

I not entirely sure if I posted this on the correct forum. Is this the right place or should I find another one? Not being facetious, just unsure.
