Testing And Fixing USB Flash Drives And Memory Cards

As a brand new kind of storage media, USB flash drives and flash memory cards start to be increasingly more beneficial in our modern-day world especially these drives. Nevertheless, have you previously come across the instances which you couldn’t start the files saved holding a flash drive or maybe memory card, even in case you can envision the file names in windows explorer?

Windows would let you know that the documents were corrupt and declined to stuff them. This point isn’t odd since the flash chip installed inside your USB flash stick has its life cycle. For instance, a TLC flash chip could just be written approximately 500 – 1,000 times before it goes bad.

An MLC flash chip can endure much longer, around 10,000 write times. When the flash chip starts going bad, it creates some unstable memory blocks known as terrible blocks, and also your files will corrupt in case they make use of the negative blocks on the flash chip.

Large Issues

And then, plug it to your pc once again, and also navigate to the windows command prompt mode. Today you can type DOS commands within a command window.

Do substitute the “filename1” with the real file on your flash drive (full course must be included), and change the “filename2” with the same file on your computer hard drive (full path must certainly be included). When the comparison is completed, windows are going to tell you whether they’ve some difference or not. In case they’re the same, congratulations, the file on a flash drive is OK. Now you can perform the comparison for the next file.

Nevertheless, in case you have a lot of documents on the flash drive, you’ve to perform the comparisons for every single file, that is a bit of bit annoying, sometimes even impossible. Additionally, in case you discover a bad block by hand using the above technique, it is not simple for you to repair it by hand, and you may have to trash the entire drive for security reason.
