Kingston 8GB SDHC card

September 16, 2012

I bought a SD card at Staples. When I check their website, Kingston 8GB, 16GB, 32GB cards are on sale.
But, when I went to store, only one 8GB on the rack. So, I have no choice to get it. It is only $8.94 with tax. Kingston is a good brand. I have some other sd card or micro-sd with this brand. Its products have good quality and you should not worry about the data in it.

See the front of card, I want to know the meaning of the standard.

SDHC
The Secure Digital High Capacity (SDHC) format, defined in Version 2.0 of the SD specification, supports cards with capacities up to 32 GB. The SDHC trademark is licensed to ensure compatibility.

SDHC cards are physically and electrically identical to standard-capacity SD cards (SDSC). The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in Version 2.0, and the fact that SDHC cards are shipped preformatted with the FAT32 file system.

Host devices that accept SDHC cards are required to accept SDSC cards. However, host devices designed for SDSC do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade. Older operating systems require patches to support SDHC. For instance, Microsoft Windows XP before SP3 requires a patch to support access to SDHC cards. Windows Vista SP1 also requires a later service pack.

How long does Memtest86+ run

January 3, 2012

It is a question, when I use a bootable CD to run it. It looks never stop.
Finally I got the answer from the forum of Memtest86+.

Memtest runs indefinately unless you stop it. It does however repeat the
same tests over and over again. Memtest86+ contains a number of different
tests which each take different approaches in trying to expose any errors
in your memory. In the top right of your screen you can see the progress of
each test in the lower of the two progress bars. The topmost progress bar
shows the progress of a pass, each pass consists of all the tests in the
memtest suite.

Thus all tests are executed in one pass, so does that mean that no errors
will show after the first pass if that pass didn’t reveal any errors? Well
no, there are several reasons why errors might only show up after a number
of passes. Firstly as of this writing, the latest version of memtest also
includes a test which uses random test patterns, each pass these patterns
will of course be different. Secondly some types of errors simply don’t show
up until the system has been running for a while or are very critical on a
certain timing condition, are thermal in nature, or other such conditions.

To conclude, one successful pass of memtest will give you a pretty good
idea that your memory is ok, only in rare cases will there be errors
showing after the first pass. To be sure though simply have the test run
overnight or even for a couple of days depending on the level of importance
of the system.
