If we type a block size bigger than the default value in Options / Block size, we can further boost the speed.ġ) What's the quickest and most accurate way of knowing the true size of this fake 2 TB pendrive (and what software) Ģ) How can I adjust this thing to only use the max size it can hold? This way we will see in a few seconds if there are issues with our device. To speed up the process, select Random Write + Verify, which will try to write data to random memory cells. The method Linear test + Verify is the most thorough, but it also takes a long time. Suffice to say this test isn't saying anything. Now let's look what happen if we use a 8 MB block size:ĭATA INTEGRITY ERROR AT 205 GB. Again the same config, but look at the new result (after a few seconds):ĭATA INTEGRITY ERROR AT 1352 GB. In the first attempt it said for RANDOM WRITE + VERIFY with a blocking size of 2 MB (insted of 64 KB):ĭATA INTEGRITY ERROR AT 140 GB. If I put the biggest block size it will end the checking after a while. I have no idea if it will take 1, 2 hours (so much less) once it reaches, say, 32 GB.Īnother program that I was told to use was AIDA64: If we try this one it will (if I am not mistaken) take more than 2 days to complete this task. Problem is that 'VERIFY' option is greyed out (not available), only write + verify.
