A rather strange case with the fraudsters’ favourite flash drive

leave a comment »


The case of sales-producer is rather unusual. This model of USB flash drive is a favourite with fraudsters in the far east for reprogramming to fake capacities. Mostly the true capacity is below 2GB, but sometimes (when they are sold as 32GB or 64GB) they have a true capacity of 4GB.

This seller advertises them as 4GB and we think this may have been their original capacity. However, a member of the frankenflash project has received two of these from sales-producer and both failed testing with h2testw.

One failed at just over 3GB and the other at just under 3GB. We wonder if this could be a result of them previously been re-programmed to fake capacities. Reprogramming of low quality flash memory can cause progressively worse failure each time the memory is programmmed to a new capacity.

We suspect this may be the case with these 4GB flash drives sold by sales-producer. In some ways this could be almost more dangerous than an outright fake as users are not likely to run into problems for months!

We strongly advise ebayers not to purchase this model of flash drive from any seller whatsoever. We have never found one of these that passed testing with h2testw. Eventually anyone using a flash memory item that fails this test will run into problems such as lost and/or corrupted files.

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 in to SOSFakeFlash if your testing confirms you have purchased a false capacity device on ebay.
