I've had this flash drive for a few months but I haven't used it very often. A few days ago when I plugged it in my PC it said it was RAW format and didn't want to show the contents unless I formatted it. So I tried but every time it kept showing 'Windows was unable to complete the format'. I looked it up on Google and found out that it could be write-protected, so I opened diskpart and removed the read-only attribute. After that it worked flawlessly, it could read and write files without any problems. However, after I disconnected it and connected it again the same exact thing happened. I think this only occurs when you disconnect it directly from the USB port without clicking on 'Safely remove' first but I can't be sure because this behaviour isn't consistent. It's really frustrating, though, and I was wondering if anyone knows a solution. Is there a way to forbid it from going in this state? Thank you in advance!

Two suggestions: repeat your procedure of removing the read-only attribute, and then immediately format it.  Many times, when getting a RAW message, the partition is damaged.

And....why not just purchase a new flash drive? They are cheap now, especially if purchasing online from Newegg or Amazon. Not worth the trouble dealing with an undependable drive.

Hey, ranchhand_!

Thank you for your reply. That's exactly what I've been doing. I immediately formatted it to FAT32 after removing the read-only attribute. However, I think I had Quick Format checked, do you recommend I do a full format?

I have many other flash drives but was just wondering if there was a way to fix this one.

When you formatted, did you first remove the existing partition and then reset a new partition encompassing the entire drive, then format it using full format? If yes, then you might try using NTFS instead of FAT32, unless there is a reason you want FAT32. Other than that, I can only guess that the drive itself is faulty.
