Dont Have Authority/permissions Ondisk After Installing Backup Options

[Chris C.L]

HI

I rescently had to rearange my partitions due to a misscalculation in how much size my system drive needed to be.
All data was stored on an external drive and then brought back in after partitioning. On my non system drives the data is messed with. Some files are locked as in its only accesable to someone elses login. Other files if i try to sae into them it sais I dont have the permissions and have to type in my password to authenticate. Lastly tobay i tried to run a library program to transfer ome midi data into a hardware synth and i get
ERROR
There is a problem accessing the SysEx files folder "/Volumes/Library/librarian files".
The folder's privileges do not allow writing.

I would be very greatfull if someone knows what the problem here is, its doing my head in.
