I decided to move my XAMPP installation to external drive. It's USB3 3TB Seagate drive. Unfortunately mysql doesn't want to start. All works fine if I install XAMPP to C drive but doesn't work when I try the same on external drive. I uninstalled and restarted computer many times, cleaned up all traces of mysql from computer, and I'm still getting the same error.
This is fresh installation and I have no data in database. I also deleted zero byte data file, like error log suggested, but file gets created again every time I try to restart.
This is the log file content:

I already tried some suggestions mentioned in other topics like this one
innodb_buffer_pool_size = 256M
innodb_log_file_size = 256M
innodb_thread_concurrency = 16
innodb_flush_log_at_trx_commit = 2
Still no change. Any help would be appreciated.
EDIT: SOLVED (see below)

After some more researching, experimenting and headache (this is bothering me since last night) I have found the solution. In addition to adding above mentioned changes to
my.ini
fileI also added this line to the end of
my.ini
fileNow everything works great. Looks like this is a bug related to large sector size on 2TB+ hard drives. Source for this solution can be found on this page.
