Too long preparing drive

[nonsequito]

I have a 200GB USB drive that I want to backup to a similar external drive.
But SD has taken almost an hour "preparing" the drive to be copied.

I use SD for 3 other pairs of drives, but this is the first time I've used it on this drive. I had backed it up previously with a different program.

The drive can be read and written to, no problem.

Any ideas as to why this could take so long...if it isn't hung up.

Thanks

Sounds like it's not responding right; I'd stop it, power everything, including all peripherals, off. Then, start up again and give it another shot.

Thanks. I closed the system, restarted, and it worked fine. Who knows?
