Keeping external drive designations

[RLDumfries]

Environment: iMac 21.5 with Yosemite, Parallels desktop 9

I have three external drives: One for data, one for Time Machine backups and one for mirror backup. Every time I reboot my iMac and load windows (paralells transparency mode), my drives get re-named. I always have to go into each of my windows programs and re-direct to the 'new' data drive. Sometimes it is W, sometimes U, and other times T.

How can I stop this from occurring?

Thanks

Hi RLDumfries,
To resolve this issue you need to map external drives as network drives, Please follow the steps suggested at http://kb.parallels.com/116127 to map the external drives as network drives and assign them with desired drive letters.

Thanks for the reply. I checked and I was already mapped to the drive (T). However, when I re-booted, the drive changed (U) and I am having to re-direct all of my windows software.
