HI,
I had similar problems when making partitions bigger on a new cloned disk... (tried several different software's...)
It started to reboot after without i could find out why ...
I also tried several times to use a SSD disk without working result. The system board has problems with these SSD's to boot from.
What I finally did is cloning the 500G disk to a hybrid hard drive (SSHD) from seagate ST2000DX001
I did not change anything to the partitions, just cloned it.
I used a 2T disk which had 8 gig of flash disk build in (1T would do the job also of course ..., you will use only 500 gig anyway)
This type of disk will boot in the beginning as fast (or slow) as a normal spinning disk, but the more you use it, it will place the most used files on the 8gig flash. The result is the system is really fast now (i have more than 55.000 music files) I supose the database is on the flash disk now..
To have more space available i connected an external USB disk (1TB SSD, because i had it already..)
and mounted this one under a directory in the music directory. (formatted the SSD on the BM5)
I copied all my music files over my internal network to the mounted BM-SHARE$ from my mac to the subdirectory where the USB disk is mounted.
I never have any drop outs when copying.. (more then 700 gig in 1 time copy)
Works for several months now without any problem and is pretty fast !
The only problem is the BS/BM5 will not see the new music files on the external USB disk directly. (like it would if you copy it to the standard disk in the music directory). But a quick reboot sees them directly and will put them under "recently added"
best regards
nico
