What Are The Problem With These 512GB, 1TB and 2TB Capacity Flash Drives?
If you’ve not heard of these before, a fake capacity flash drive is simply a small low capacity flash drive pretending to have (much) more storage. The clever / devious part is that they may have only 16GB of real storage, but can appear to the computer as anything up to 2TB. You will be able to copy data to the device, but only the first 16GB may be readable later. Some devices constantly overwrite the same 16GB while other just dump the rest of the data into a back hole
How Do I Know If My 512GB, 1TB and 2TB USB Drive is Fake?
There are not any strict rules, but you can start to build up a picture as you gather more information.
- Price – These flash drives will be WAY cheaper than anything you can buy in a retail store. We just bought 512GB flash drives for £10 and 1TB drives for £15. Currently a 64GB SD card is £32.48 at Novatech, so you can see how expensive real flash drives should be.
- Quality – Large capacity USB drives are relatively expensive. You’d expect them to be well made and probably well packaged. The fake drives usually come unbranded, in generic clear bags.
- Wording – Since these problems have been reported, some sellers are putting some disclaimers on the listings to suggest you should only use the devices for small amounts of data etc. This is obviously nonsense. If you buy a real 1TB of storage, you can use all 1TB.
- Testing – Although most people won’t be familiar with testing hardware, there are some pretty simple tools to test USB drives. They write patterns of data to the chosen device and then read it back again to make sure it was written correctly.
What To Do If You Have A Fake 512GB, 1TB and 2TB Capacity Flash Drive
Most online marketplaces like eBay have pretty robust buyer protection to allow you to claim a refund. The advice for making claims varies with each website so you may need to hunt around, or contact the site directly. Although eBay are more than happy to organise refunds, they show little interest in stopping the sale of these devices. We’ve spoken to eBay customer services a number of times and they said that their system will flag up if enough people make returns.
You Often Don’t Know Until It’s Too Late That Your 512GB, 1TB and 2TB is Rubbish
It’s a bad idea to keep using one of these USBs. If you detect a fake capacity, you may think it’s OK to just use it for small amounts of data but it’s not a good idea. The problem is that as you use and delete files, you could gradually start edging towards the limit of the storage. The next file you write could just go into the black hole, and the data is lost. In fact, many people don’t realise their flash drive is a fake until they exceed the “genuine” part of the storage. If you were copying photographs to the USB drive, you might not notice that some of them are missing until you try to read them again much later.
Not Just Memory Sticks
These same types of fake flash drives also appear as SD cards so we’ve heard from people that were at weddings or on their honeymoon and lost all or most of the photos.
