Hello,
I tried to reproduce this bug by mounting/unmounting the drive several
times.
It seems like this problem is caused, if the drive is at speed 0 after
some time without access. In this situation, sometimes the drive seems
to take a bit longer to speed up. Whenever it takes a bit longer, I get
the error in dmesg and parts of the mounted disc are unreadable...
Any chance to get this debugged?
It's not entirely clear to me whether the kernel is doing any retries or
not. It likely should be, but somebody more familiar with the block
layer would likely have to answer whether it will be or not..
Certainly if we are already retrying and the drive keeps saying "no seek
complete" there's not much the kernel can do about it..
