I'm very dubious. I tried using those 1.8" Microdrives perhaps a

to spin up again.

Is that within the drive, or is it the iPod firmware that requests the spin-down?

Did anyone here use an 1.8" drive with the Pi? Via USB?
Experiences would be interesting to know of.

The drive's firmware so you don't have control over it. This was
in a Neoware thin client.

Ok, I'll then try to

echo $(date) > /tmp/date.dat

every other second or so, to keep it spinning

but they only got as far as 16GB, which is a bit disappointing today.
Would be enough to boot a Pi (or thin client) for laughs, though.

In one of my photo bags is a small drive with rechargeable battery
(after all these years, probably won't hold a charge -- good thing the
drive can be used from charger plug). The unit had slots for all 5 major memory card formats of the period.

One would insert a card, press the copy button, and the card contents
would be copied to a (newly created) directory on the drive.

Problem these days? It is a 40GB (unformatted) drive -- and the camera
in that bag now has 32GB CF cards! (Maybe a few 16GB, but I think I moved those to the other camera [8Mpixel vs 15Mpixel], and moved that one's
8&4GB
cards to the even older 4Mpixel P&S camera [I'd been using a 256MB card in that camera, had a 64MB card for secondary, and the factory provided card
was a whopping 32MegaBytes -- could only hold about 12 photos!]). Could
only back-up one filled CF card (and you don't want to do multiple backups while filling the card, as each backup copies everything).

Presumably you would use the copy-from-CF-to-HDD device just for making a safety copy while you are away from home (or freeing up space on the
camera's CF card), and you will empty its drive once you get back home and
save all/most of the photos to permanent storage. Given that, how often will you fill up 40 GB while you are away from your permanent-storage computer?

They were/are a good idea: more portable than taking a laptop and maybe an external USB hard drive, though a laptop does give you the ability to
preview pictures and determine whether there are any problems that may need
you to re-shoot photos. A camera's back-screen is OK at a pinch, but not as good for showing exposure/focussing errors.

Can it take SDHC (the high-capacity version of SD) cards? Since your camera uses CF rather than SD, it may not matter, but it's always worth having something that cam copy SD in case you need to back up contents of a
cellphone etc which uses SD. I also carry around in my cellphone case a micro-SD to normal-SD adaptor so I can read a micro-SD card (from a phone
etc) in a computer that only has a normal-SD slot.

Hard to state -- For the dSLRs I'm configured to save both RAW and JPEG in parallel. Without digging up the camera, I think that comes to about 900 images (from the 15Mpixel) per 32GB CF card.

It was useful back when my CF cards were in the 1-4GB range (I actually have a mixer/recorder -- BOSS BR-600 -- that won't work with a CF card
larger than 1GB!). I could fill a card with images from a day out, then
back it up to the portable drive.

Can it take SDHC (the high-capacity version of SD) cards? Since your camera

I suspect not -- it is ancient <G>

uses CF rather than SD, it may not matter, but it's always worth having >something that cam copy SD in case you need to back up contents of a >cellphone etc which uses SD.

The SD card in my phone is barely touched...
