<!-- PLEASE READ THIS CAREFULLY:

1. You MUST read and complete the steps from the checklist below, by placing an x into each [ ] (so that it shows '[x]', NOT '[ x]' or '[x ]'), BEFORE clicking on 'Submit new issue'.

2. Failure to perform these steps, WHICH ARE ONLY THERE TO HELP YOU, will usually result in your issue being dismissed without notice.

3. If you are reporting an issue when trying to run Rufus, or when trying to boot a media created by Rufus, you MUST provide a log, period. Please do not assume that the developer(s) will be able to "guess" the specifics of your environment, what image you used, what type of media you used it with or the many many other critical parameters that the log provides data for. To investigate an issue, a log from Rufus is ALWAYS required.

4. If you still choose not to provide a log when reporting a problem, you agree that your issue will be closed without any further investigation.

YOU HAVE BEEN WARNED. -->

Checklist

• [x] I looked at https://github.com/pbatard/rufus/wiki/FAQ to see if my question has already been answered.
• [x] I performed a search in the issue tracker for similar issues using keywords relevant to my problem, such as the error message I got from the log.
• [x] I clicked the 'Log' button (🗒️) or pressed Ctrl-L in Rufus, or used DebugView, and copy/pasted the log into the section that says <FULL LOG> below.
• [x] The log I am copying is the FULL log, starting with the line Rufus version: x.y.z - I have NOT removed any part of it.

Additionally (if applicable):

• [ ] I ran a bad blocks check, by clicking Show advanced format options then Check device for bad blocks, and confirmed that my USB is not defective.
• [x] I also tried one or more of the following:
  • [x] Using a different USB drive.
  • [x] Plugging the USB into a different port.
  • [x] Running Rufus on a different computer.
• [ ] If using an image, I clicked on the (✓) button to compute the MD5, SHA1 and SHA256 checksums, which are therefore present in the log I copied. I confirmed, by performing an internet search, that these values match the ones from the official image.

Issue description

EastFun 8GB flash drives are not compatible with Rufus 3.22 (Windows 7 Professional, Windows 7 Home tested). Issue is not related to anti-virus or other software(s). Safe Mode generates identical error. Other report found at this link: forum [dot] puppylinux [dot] com/viewtopic.php?p=65926 (see confirmation post dated Fri Sep 09, 2022 3:08 pm). Substituting an 8GB Kingston flash drive results in immediate success.

Suggest you add a note in the FAQ section for error "Error [0x00000005] Access is denied" mentioning deficient flash drives as a potential cause.

Considering that, per the FAQ, I have stopped supporting Windows 7 in any way shape or form, and the only reports I am seeing are from Windows 7 users, I am not planning to do anything about this.
