Reformatting a WD purple drive
Hi, I have acquired a ¡°purple¡± (Surveillance hard drive) western digital 2 T hard drive . I want to format it using my raspi but I do not have the permission to get beyond the cache. I would like to drop to sudo su command line but I am unsure what utilities I can call to wipe and format. This drive was from a broken Lorex surveillance system owned by my friend who owns a hardware store. I want to repurpose it to the rasp. I am using my universal adapter kit to fire it up and read the directories but the 2020 video library is basically the whole disk. Gotta get rid of it. Any insight is appreciated. Rich, ve3DCC

If nothing else is needed, use one of your older Pi units to run PiHole. I have a RPi Zero W sitting by itself in the shack, connected to only an old cell charger, that strips around 25% of the pop-ups and crap from all the devices on my home network. Pretty easy to set up and works great.

I have two of those exact units. Mine has HDMI, composite video, 3.5 mm mono audio, Ethernet, 2 USB, and the SD card slot. One of them is configured to block ads on my home network. It does a great job. The other one is just used for experimentation. I have a 4 that mines crypto currency. I have already made $2 since January. Another 4 runs HamPi. The originals are still useful for things that do not require intensive processing, 32 bit only, and without the desktop environment. Still not bad for 11 year old computer technology. ?

Good points.? The kit appears to include a stylus, so I'm assuming
the display is of the resistive type.?? I have a 5" resistive touch
display (HDMI-based), and on a display that small, the use of a
stylus is actually an advantage.? They're a lot sharper than my
fingers.
I expect your other points will determine how useful the product
will be.

That's amazingly cheap for a metal case + display
+ fan though a few things:
?? - What do you intend to use your
Raspberry Pi for?? For example, what programs do you intend to
use?? Also.. how good is your eyesight?
?? - That LCD display is connected via the SPI bus on the 40pin
header.? It doesn't use either of the HDMI ports or the DSI
connector so it will require drivers to work and the display
performance might suffer.? The bottom of the details page says
"1 x 5FPS touch screen".? If "FPS" means frames per second
here... that's very very poor,
?? - That LCD display board uses a LOT of pins on the 40pin
header.? If you're using other pins on the header for projects,
you might have issues
?? - There is no mention of the 320x480 display's touch type.?
Is it capacitive (good) or resistive (bad)
?? - I like the idea of the heat spreader and fan but the gap
between the metal spreader and the fan is going to make the fan
most ineffective.? The metal spreader looks to be aluminum or
pot metal so it's thermal conductivity is going to be pretty
poor

Please share the links for both the display and the compatible case as I have a couple of projects for this style case and display.

I was just wondering if anyone has tried to use one of these cases with the 3.5" display for portable operations  It would be a small screen but it could be handy for portable use. One less thing to pack on the trike.? Let me know if you have or not or if you think it would be more headache than what it is worth.?

Hi Aaron,
I still have my original Pi and it still works. Keep in mind the limited resources. Mine will try to do multitasking but it runs out of gas for bloatware. Mine didn't do very well with sound card applications - heavy DSP processing. I used it with a an IRC client on the web to have live chat with other technical folk while running a second (lightweight) app or two. Logging is a good application. Command line interface (CLI) works very well - even for multitasking. Open more than one terminal. The 'latest, greatest razzle-dazzle' web browser will crawl along (or fail) but the lighter browsers work okay on that old pi. I sometimes use it for a journal or other writing projects.
Since you already have them you have nothing to lose putting them to work.
73,
Bill KU8H

Re: Preliminary Speaker Scheduled Announced - ARRL/TAPR DCC (Digital Communications Conference), Charlotte, NC, September 16 - 18
Maybe because these groups are here to disseminate information of interest to hams? Because this digital conference has all kinds of neat things to share about various digital modes used in ham radio and many of those are incorporated on RaspberryPi platforms? Maybe because the OP thought people on this list would appreciate knowing about these kinds of events?
Maybe because they figured if you were not interested, you'd just have the decency to hit the delete key and move on instead of anonymously whine about it.
