WARNING - USB Drives may not work when Drive Monitor is installed
Today I wanted to sync some data with a USB disk, this had never been an issue before, just plug it in sync the items eject it, job done.
However today when I plugged the drive in it appeared in explorer and when I tried to sync it disconnected (stopped working). Given I had installed several items over the last few days with timely backups taken I have restored several to try an isolate the issue.
After a time I began to realise that the drive stopped always in the first minute - it worked for a period then went AWOL. From conversations elsewhere I then thought Drive Monitor, - it tries to grab S.M.A.R.T. data every minute from the drive.
After this I uninstalled drive monitor an lo and behold normal service was resumed.
I then restore my latest backup taken this morning with all the other items that had happened over the last few days, uninstalled Drive Monitor and tried the sync and it worked just fine.
I therefore believe that Drive Monitor is the guilty party in this case.
FYI I also tried several different USB disks some USB powered and some with an external supply all had the same issues within 1 minute they stopped working. When this happens the system becomes unusable until you unplug the drive then everything springs back into life.
I am using Windows 7 64 bit as the OS.
