Card Reader |
|
|
I just bought a Dynex CF card reader (Model: VPN: DY-CF131). It came with
no instructions whatsoever. Seems to work fine, although the cards are a
little difficult to engage on the tracks; once positioned however, they
seem to slide home satisfactorily.
My question concerns when to load the media. Does one first connect the
reader to the USB port and THEN load the card? Or can the card be loaded
before the reader is plugged into the computer? And what is the correct
order for taking the card out?
Thanks.

My own experience with different cards, readers, and PCs, I've never had
a situation that made me think it matters.

Do whatever works. At least on Mac OS X, if I plug in a card reader with
a CF card already in the reader, my Mac won't see it. I have no clue if
Windows behaves the same way or if this behavior varies from one card
reader to the next. If both methods work, then pick whichever one works
best for your work habits. |

It makes absolutely no diference. All methods usually work.

Interesting!

safe to remove/unplug a USB storage-class device that doesn't have
dirty buffers. Thanks for getting me to examine my old hard-
learned habits. :-)
|
I should note that I never write to the CF card other than
to delete files. The actual command is a /mv/ command. I
usually do umount it before pulling the card, but have many
times forgotten to do so without any dire results.
| Quote: | As for mounting it originally, that does get wierd. With a USB
card reader you don't want the card in place when the system is
booted, for example on a laptop. I'm not sure about the reader
(it may not matter, I haven't tried). Plugging in the
reader/card causes the necessary modules to be loaded, and that
won't happen if the card is already in when it goes through the
initialization process at boot time.
Ummm... Are you sure? My setup is perfectly happy to load the
usb-storage module and connect it to /dev/sda1 if it sees my camera
connected on bootup. It just works.
|
Mine definitely doesn't. If I boot with the CF card in place,
I see nothing until I pull it all out and plug it back in.

I have some other things that may be there, but they will either
not be available, or will already be mounted.

Windows 9.x does not use much beyond 128MB efficiently. There's really

It's not so much a case of small market share. In the case of OS X, you
have to enter the admin password to install software. Windows lets
anybody that logs onto the machine install whatever they want without
asking any questions. |

That's an odd thing to say. I had new hardware with 1GB of RAM and I
needed some flavor of Windows in order to run Tax Cut. I had a copy
of 98SE and didn't want to pay the steep price for XP. 98SE didn't
just run inefficiently on my hardware. It reliably locked up. It
didn't matter if I fiddled with the registry to get it to ignore RAM
above 512MB. It always locked up soon after booting. Pretty
embarrassingly stupid software.

It's possible to differ over the relative importance of being a small
target versus having a secure design. Windows partisans sure like
to claim that market share is the entire reason Unix-based platforms
are almost never attacked. But, you and I both know Windows' ease of
use translates directly into ease of hacking. Fortunately for us,
Unix-based platforms like OS X and Linux are easy to use without leaving
the door wide open.

Put the media in the reader and then plug into the pooter. After |
unmounting, do the reverse.
With Mac OSX an icon will pop-up on the desktop - double click to open
or simply let iPhoto do it's work. On no account should you delete the
pictures on the media with iPhoto.
With Windows, the icon is usually within My Computer - called 'removable
disc' or something.
You should unmount the reader before unplugging. On the Mac click the
icon and Command + E. In Windows, click the icon next to the clock and
unmount. |

It may be bad for performance in the long run too.
I have a dual-CPU computer. When I run a single graphics-intensive
program under Windows, the one CPU becomes saturated while the other one
sits completely idle, I presume because the graphics code is running in
the kernel in the context of the user code that is calling it. There's
no second thread or process to run, so the second CPU is wasted unless
there's also a background process to make use of it.
Running Linux on the same hardware, a graphics-intensive program uses
*both* cpus. This is almost certainly because the X server is a
separate process, and will happily run on one CPU while the other is
running my program. The machine feels faster too.
The CPU vendors have pretty much exhausted the easy speed increases
available from higher clock rate and deeper pipelines, and both AMD and
Intel are now going to multiple real CPU cores for higher performance
(In addition to Intel's hyperthreading, which is a weaker version of the
same idea). So having graphics as a separate process is a better idea
now and for the forseeable future.
Not to mention the security issues, or the flexibility of running a
compute-bound program on one machine while the X server is on a
different machine.
