Hi, I got suddenly a question mark and every time i rebooted it cames back. so I have fully formatted my disk in the cmd R session. Even with the cmd R my disk is not always there. And when it’s there, I get an error if I try to reinstall MacOS Sierra on it. The error is Bad file descriptor. MacBook Pro 15’ 2017 1TB SSD
The phrase bad file descriptor is often associated with file system issues, but is not amongst the strings in fsck_hfs or fsck_apfs.
You'll find the phrase in /source/xnu/xnu-3789.51.2/bsd/sys/errno.h in open source for Mac OS X 10.12.4.
Consider the possibility of an underlying issue with the drive.

It appears to be when the download or writing the file is failing, its every time at the same "Chunk" :

Thanks.
At a glance, I don't know whether to treat those I/O errors as symptomatic of a local problem.
> … Failed to allocate edge cache locator.
– that's thought-provoking. Can anyone else comment?
