That duh moment when you cannot read an SD card: it’s SDHC/SDXC in an SD card reader; Secure Digital – Wikipedia

Posted by jpluimers on 2019/02/18

That moment you facepalm yourself because you forgot that particular machine won’t read SD cards because they are too big for the SD card reader in it: SD goes up to 4 gigabyte, anything bigger (nowadays basically everything) requires SDXC or SDHC compatible readers.

Quotes from Wikipedia:

However, older host devices do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade.[11] Older Windows operating systems released before Windows 7 require patches or service packs to support access to SDHC cards.[12][13][14]

Older host devices generally do not support newer card formats, and even when they might support the bus interface used by the card,[6]there are several factors that arise:

  • A newer card may offer greater capacity than the host device can handle (over 4 GB for SDHC, over 32 GB for SDXC).
  • A newer card may use a file system the host device cannot navigate (FAT32 for SDHC, exFAT for SDXC)
  • Use of an SDIO card requires the host device be designed for the input/output functions the card provides.
  • The hardware interface of the card was changed starting with the version 2.0 (new high-speed bus clocks, redefinition of storage capacity bits) and SDHC family (Ultra-high speed (UHS) bus)
  • UHS-II has physically more pins but is backwards compatible to UHS-I and non-UHS for both slot and card.[27]
  • Some vendors produced SDSC cards above 1GB before the SDA had standardized a method of doing so.

2018 Hard Drive Reliability Stats by Manufacturer and Model

Posted by jpluimers on 2019/02/11

We look at the hard drive failure rates for the data drive models in operation in our data centers in 2018 (now totaling over 750 petabytes and 100,000 drives). In addition, we’ll see how the new hard drive models we added during the year did, including our 12 TB HGST and 14 TB Toshiba drives.

Since my brother has this motherboard: M4N78 PRO GREEN.

It does WOL, but doesn’t always wake up when powered down.

ScanSnap ix100 info you don’t find in the Getting Started guide easily

Posted by jpluimers on 2019/01/28

Always fun when Getting Started guide makes it hard to find essential information, but the installation mentions it after installing:

ScanSnap is initially set to turn off automatically after a certain time of non-activity.
The power-off interval can be changed from the [ScanSnap Manager – Preferences] window.

To turn the ScanSnap back on, perform one of the following:

  • Press the [Scan] button
  • Close the ADF paper chute (cover) and open it again

The installer then continues to ask to connect it over USB, though the Getting Started guide mentions you can connect over WiFi.

There the “monkey gets out of the sleeve” as the WiFi installer mentions this:

ScanSnap Wireless Network Setup

To start up the Wireless Setup Tool, perform the following:

  • Turn on ScanSnap
  • Turn on the Wi-Fi switch on the ScanSnap
  • Connect ScanSnap to the computer via the USB cable

(i) If you start up the Wireless Setup Tool via Wi-Fi, some functions are not available.

Too bad it doesn’t explain which functions are not available, not even a web-search or the [WayBack] manuals:

Philips Brilliance 240B max resolution: 1920 x 1200 pixels at 24 bit

Posted by jpluimers on 2019/01/25

Since the Display on the frontside is labeled as “Philips Brilliance 240B”, finding the actual supported maximum resolution took an additional step resulting in these specs: [WayBack] Specifications of the LCD monitor with Ergo base, USB, Audio 240B1CB/75 | Philips

This is what I needed from it:

Philips Brilliance 240B max resolution: 1920 x 1200 pixels at 24 bit via either of the inputs

  • VGA (Analog )
  • DVI-D (digital, HDCP)
