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).
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.
Preparing SDCards
The SDCards contain the OS and the UMMSPI configuration. I used the following image on the SDCards:
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:
- http://www.ummspi.net/histology/
- http://www.ummspi.net/phpmyadmin/ (also a MySQL test!)
- http://www.ummspi.net/rasppi/
- http://www.ummspi.net/eyes/
- ssh pi@www.ummspi.net (to verify remote access)
- using a Windows machine:
- mapped www.ummspi.net\public drive
- installed ImageScope_v12.0.1.5027.exe found on the public drive
- tested the ImageScope program using "slides" found on public drive in \Portable Histology Project\Slides
All of these worked, which indicates success.
