Fighting flash fraud on Ebay

The authors of this blog want to elimnate flash fraud on Ebay

flash drive, memory card or MP3 player not working

Many thousands of people will have receive a memory card, USB flash drive or MP player as a Christmas present. A lot of them (especially if your well-meaning friend or relative purchased on ebay!) will turn out to be fakes. A fake flash memory item cannot save the amount of data advertised – few can really save as much as 4GB – most can’t save more than 2GB.

If you have a problem with accessing files on the USB flash drive, memory card or MP player you got in your Christmas stocking it is likely that you got a fake. There is a very handy little program called h2testw you can use to check flash memory – we suggest you use it!!

We advise everyone who buys flash memory items to test them with the free program h2testw irrespective of where they were purchased – otherwise you run the risk of data loss and corruption.

Report your fake if testing confirms you have purchased fake capacity flash memory on ebay

  1. fightflashfraud makes some useful suggestions about testing any flash memory with h2testw, this will be easy with the USB type of flash stick, a little less easy with the flash card unless you have a specific reader to adapt the card to a USB port.

    Many MP3 players that use flash memory as storage come supplied with proprietary programs to make up and down loading music files easy, in many cases that can insulate the user from direct access to the memory chip, and thus isolate it from any tests using h2testw. Some players have a menu option to allow the players memory to be directly accessed by a USB port, you need to select this option before so h2testw will be able to recognise the memory as an external drive.

    Then if all goes well, you will be able to treat the MP3 player’s memory just like it was a native USB stick.

    Where proprietary software prevents this, you may find just connecting the Mp3 player via it’s USB lead to your PC and NOT using the special program installed to communicate with the player, but letting Windows find this player and treat it as a standard USB external memory, this should work and allow the full access for read/write that h2testw needs.

    If you have already loaded songs on to the player, h2testw should avoid overwriting them, and will report the effective capacity minus the capacity used by the recorded songs, however if the flash memory in the player is false capacity, it may already be too late as the real memory content could have already been overwritten. If you find songs no longer play correctly, even before you try h2testw, then suspect false memory, in that case you will need to completely erase (format) the players memory before running a full test to establish the REAL capacity.

    This can be done using your PC format command, but be VERY careful to format the correct drive, best if you are unsure, to use the inbuilt program to empty the drive first.

    Please remember that however you connect your player to your PC, if it contains false capacity memory the PC will report what the control chip is programmed to say, and not true ACTUAL capacity of the internal memory chip. The PC will happily write over and over to the same part of the real memory that is accessible, as long as it reads back what it writes to each memory cell, it will be happy. H2testw does this test in such a way that what it writes to the cells is dependant on the actual address of the cell therefore a unique pattern is written which can be recognised, and any sections of memory that are written over subsequently will show incorrect data on the final check readout, this will indicate that the memory writes have exceeded the true capacity, and this will be reported in the final analysis.

  2. We read all “Old wives tales” about flash memory, it’s use, it’s fragility specially in transport through airports, many are untrue, there are millions of devices with flash memory passing daily through our airports, what collected statistics there are do not seem to indicate a major problem, however it is advisable to take care of these items, most are physically fragile, easily bent, or fractured if dropped.

    One of the major manufacturers of flash devices has this to say about protection of it’s products, well worth a read…
