Test your pen drive / USB sticks with H2testw

H2testw was developed to test USB sticks for various kinds of errors. It can also be used for any other storage media like memory cards, internal and external hard drives and even network volumes. The executable file H2testw.exe needs no installation and can be directly run. It was developed for Windows XP and Vista. It should also work under Windows 2000 but was only tested on XP and Vista. Windows 9x/ME is not supported. You can use the older command line program H2test under these operating systems. The function of H2testw is quite simple: It fills the chosen target directory with test data and then reads it back and verifies it. H2testw does not overwrite or erase any existing data. It doesn’t do any low-level tricks so administrator privileges are not required. If your hardware is working properly H2testw will not harm any existing data. You can download it from here

my camera says the memory card is full when it isn't


If you have a memory card (e.g. SD card) that happens to be a "fake" (or counterfeit), it may give you this error. Often, such a card has less storage space than what it claims to have, e.g. it is labelled as an 8GB card, but it is really a 2 GB card, or have much less than 8 GB.
Such a ("fake") card may have (internal) data that says it has (say) 8GB ... when you insert it into your PC. But if you test it, e.g. using H2testw (a free utility that you can download and run ... i.e. no need to install on your computer), it will show you the real size of the storage capacity.
So, if your (fake) SD card happens to be full, your camera would be trying to store more pictures on it, and it would not be successful, or (sometimes, even worst), it will say it is stored, but it really is lost.

how do you connect storage media


Storage Media is just an USB stick or any type of memory stick (xd card, sd card, cf card, even micro sd is considered 'storage media') If you are trying to update and it is asking you to insert the firware with the storage media, you will have to put the files on a usb stick or any type of storage media and then insert the card in either the memory card slots (if you have a original 60/80g launch model), or use a memory card reader.

I hope you understand. Please post a new question if you need further assistance or click chat on my page.

Testing mp3 player memory


Hi there. There is freeware / shareware available called h2testw. This free software will write test data to your device and then verify it has been stored correctly. By this method it can tell if a device has real or fake memory. The program will test any free space on the player so will work best when no music is on the player. The software can also be used to test USB memory sticks and phone / camera memory. I have a copy of the software on my public skydrive. Download it from http://cid-9252ebea9e3d9865.skydrive.live.com/browse.aspx/.Public. Hope this helps.
