I have a Macbook Pro running current Sierra 10.13.4, and a Buffalo external disc drive BRXL-PC6U2 connected via USB. This external drive has worked well in the past with this mac.
The device is indicated in the "About this Mac" - "Systems Report" - "Hardware" - "USB", it is 'lit up' receiving power via the USB, and it is going through the motions of reading the disc inserted into it.
The external drive, however, most importantly is not indicated in Finder (pref to show devices is 'on') or as an external device in Disk Utility. I am unable to use the external drive because the laptop does not appear to see it properly. Could I be missing drivers or some other software which is not allowing my mac to see the Buffalo device?
Help!
