1) I thought to check the hard drive speed following instructions at
http://www.upubuntu.com/2011/07/how-to-test-read-speed-of-your-hard.html

/dev/sdb1: Timing buffered disk reads:  34 MB in  3.05 seconds =  11.16
MB/sec
/dev/sdb2:  Timing buffered disk reads: read(2097152) returned 1024 bytes
/dev/sdb3: Timing buffered disk reads:  38 MB in  3.06 seconds =  12.44
MB/sec
/dev/sdb5:  Timing buffered disk reads:  30 MB in  3.19 seconds =   9.39
MB/sec

The reading for usb flash drive 2.0:   Timing buffered disk reads:  50 MB
in  3.03 seconds =  16.49 MB/sec

I plugged the hard drive into another usb port and it made no difference.

2) I ran a hard drive test for 2 hours and I got no errors.  Used GS
smartcontrol.

3) Sysem profiler and benchmark says the Toshiba is connected to a USB 3.0
port.

4) Using pv hdparm I got these read/write test results

gary14 at gary14:~$ dd if=/dev/zero of=/tmp/test.data bs=1k count=128k
131072+0 records in
131072+0 records out
134217728 bytes (134 MB) copied, 0,748769 s, 179 M

5)  I disabled ureadahead.   Per the boot chart is saves about 40 seconds.
 But still a total of 2 min 45 secs from selecting Ubuntu to being able to
run a program.

I think it might be wise to just reinstall but I will leave this for a few
days from now in case anyone has a brain storm.

Thanks everyone for your thoughts and suggestions to date.
