[edit] Prepare the WD My Passport Disk

These are the disks that are used: WD My Passport 1TB Portable External Hard Drive Storage USB 3.0

This disk was formatted with 2 partitions:

• 900GB NTFS partition for Histology Application/Data
• 100GB Ext3 partition for MySQL data

The tool used to format the partition was EaseUS , a Windows application. (I used this on a Windows 7 "VirtualBox" running on my Macbook because it was the simplest way).

[edit] Populate NTFS partition with Histology Content

Given the need to read/write to NTFS formatted partitions, one could either do this "copy" using a Windows machine and/or using a Mac with some additional software. I acquired Tuxera for $31 to permit me to do the copy directly from my Macbook, which speeds up the USB 2.0 activity by not having to run the 360+ GB transfer in a "Virtual WIndows" machine.

Of course, this meant I had to also copy the EXT3 partition manually, which I did using a "Virtual Ubuntu" machine on my MacBook. This entire copy process took a couple of hours, due to the slow speed of USB 2.0 (Remember, I was copying nearly 400 GB of data!).

I decided to simplify the process by using Clonezilla, which copied one entire drive to another. This also took several hours and appeared to take longer than copying files. I wasn't surprised, since the "clone a drive" copies physical blocks. It does require less "work" by a human being.

In any case, some of the disks were populated using Clonezilla, some by using EaseUS & then copying files.

[edit] Preparing SDCards

The SDCards contain the OS and the UMMSPI configuration. I used the following image on the SDCards:

[edit] Test/Validation Suite

Here's the testing I did to confirm that the RPi's were working correctly:

• mounting the "public" directory (Roger's 300 GB of Histology)
• mounting the "other" directory (in case someone plugs in a different disk)
• accessing the following web pages:

1. http://www.ummspi.net/histology/
2. http://www.ummspi.net/phpmyadmin/ (also a MySQL test!)
3. http://www.ummspi.net/rasppi/
4. http://www.ummspi.net/eyes/

• ssh pi@www.ummspi.net (to verify remote access)
• using a Windows machine:

1. mapped www.ummspi.net\public drive
2. installed ImageScope_v12.0.1.5027.exe found on the public drive
3. tested the ImageScope program using "slides" found on public drive in \Portable Histology Project\Slides

All of these worked, which indicates success.
