Hi
i have old disk from apple computer with bad sectors
im trying to read data from him
I would like to know if my behavior is appropriate
1. im read data using fast copy like this

+/- 87% data read, but what happend with "Read Reminder" ?

2. secend round with this settings

However, the data is being read very slowly (if I understand correctly, it is understandable due to the high timeout)
3. In future readings, I plan to increase the timeout and reduce the number of skipped segments after an error is detected.

And here's my question: is this approach correct?

I will add that I do not need all the data from this medium, only the zip file (divided into several parts)

Additionally, I found something like this on the internet, MRT + UFS

However, I'm not entirely sure how it works. If I connect MRT to UFS, does UFS use the data already read by MRT? Or does MRT only operate as a data interface, and does UFS control what gets read?
