#3 guymager instability

[vincenzo]

SCENARIO:
I tried to use Guymager to make a clone of a usb stick with 8 gigabytes on a hard disk drive of 120 gigabytes, previously filled with data for approximately 40% (I know that the combination 8 - 120 is disproportionate, but I did it the same).
Obviously all the data in the hard disk disappeared and remained only the cloned partition.

I used Guymager to detect the image (in order to recover data from the hard disk with the usual forensic tools) .
As a target for the image I used a second hard drive of 500 gigabytes, formatted NTFS.

WHAT APPENED:
Guymager started and after an hour's work found 700 bad sectors hard disk clone, reduced its speed to 0.5 Mb / s and told me that it took about 144 hours to finish the copy and that he had just copied 2.6 GB up to that point.

My question is: why Guymager slows and incredibly increases the time for copying?

Tips are welcome.

Thanks in advance

Best Regards.

Vincenzo.

Yes, that's Just normal if you clone a drive. Maybe you wanted to acquire an image instead, where all the data from the source drive is copied into an image file,

My question is: why Guymager slows and incredibly increases the time for copying?

The drive you wanted to image had bad sectors. Hard drives generally get really slow when they encounter bad sectors. This has nothing to with Guymager. Guymager asks the drive for reading a sector and the drive takes an eternity before telling back that the sector is bad. Most drives try hard to read the bad sector (sometimes you even can hear the drive readjust its heads several times) and finally fail if they didn't succeed after several retries.

Just a small remark: Your title "Guymager instability" definitively is not the right one for the phenomenas you observed. In fact, from all the feedback I get I can tell that Guymager is rock stable.

Thanks very much for your time.

Your reply has been clear and solved any doubt.
