Hi Guys/Girls

I've recently started using DJ Pro on a 2015 Macbook Pro running High Sierra
my music library is on an external NTFS formatted Western Digital passport drive and Pragon NTFS for Mac to read/write.
I previously was Serato DJ using the same kit abeit on Yosemite.

I have encountered an intermittent issue and trying to pin point if serato dj pro is having an influence.
several tracks that previously were (uncorrupted) and playing ok are now appearing in my library flagged as corrupt and display 0mb file size and 0m00s time length, it appears to be become more frequent but can not identify a root cause or action. but only appears to be an issue since upgrading both OS/Serato Software

I have a large library 20k + tracks
I purchase all my tracks from legitimate sources, juno,7digital, band camp ect and have no cracked software on my mac.

is there any one experience similar issues
i intend to have a purge and clense of my library soon to shift any deadwood but worried some of exclusive tracks/VIPs ect may end up getting corrupted
thanks Jason
