This sometimes causes problems which cause Linux to refuse to mount the device read/write. Windows can usually fix it, though I suppose there may be data loss. It's entirely possible that doing the same thing on Linux would sometimes cause similar problems. -- Joe

Hello Cindy. Hello group. Thank you for you email. Sorry, I did it in a bad way describe. I put the USB stick in, and I can see all files on the USB stick. But I cannot destroy them.

Following tips regarding hiberfil.sys fixed it both times for me, but the method comes with a harsh "this is your last ditch option" warning about things like that data loss. That's on a non-Linux system, by the way. Linux triggered the second episode while while the affected partition was mounted only as a resource for backing up images. It wasn't mounted as an operating system. There's a recovery partition that keeps getting mounted even though I'm not touching it this week. I can't help wondering if that plays some part in how that partition ended up locked down when it wasn't used as the primary operating system..

Hello Joe. Hello group. Thank you so much for your Emails. How can I make an USB stick only readable but not writable? How can I make an USB stick which is only readable again writable? Thank you.

Hello Joe. Hello group. Thank you for your Email. We have about 10 or 20 USB sticks, and nearly every day everything is working fine. But now we have 1 stick which is not accepted. We could find out, you can read files, but you cannot write on the stick and you cannot destroy on the stick. How can we make this stick writable again? Thank you.

You didn't tell us what you actually did, and especially which bits you think might be a mistake, so it's very difficult for us to answer this question. For example, you might have hit them with a hammer, or connected them to the wrong voltages, or washed them in a bath, or who knows what? Or you might have plugged them in correctly but used some sequence of commands that has caused a problem. But until you tell us what you did, we can't know which bit was wrong! > Thank you. > > Regards, > Sophie

Hello group. Hello Joe. Thank you for your Email. Sorry, I did bad asking. So I split the question. 1 How can I repair USB stick which is readable but not writable? question 2 What did I do wrong to create this problem? Thank you.

The messages will vary a bit, but you are basically looking for a) many lines of output b) that a USB device is recognised c: that it is allocated a drive designation e.g. sdd d) that any partitions are listed as e.g. sdd1, sdd2 etc. The first three items are essential for the stick to work. If they don't happen, something is broken. If the first two do not happen, the stick is probably permanently broken. There may not be any partitions on the stick, many sticks are formatted as one memory range, and do not even have a partition table. This should allow you to see which of your sticks are completely destroyed, and which may be recoverable. There have been USB sticks with a tiny read-only switch fitted, but I haven't seen one like that for many years. If not, your read-only device may have a filesystem too corrupt for the software to risk writing to. Also, Windows seems to be able to leave sticks in this state if they were not properly unmounted. If that is likely to have happened, it's possible that Windows can fix it without reformatting. Assuming a stick has been given a drive name, then fdisk should work on it, and should show the size, any partitions and other data. fsck should also work and show any filesystem corruption. fsck can probably fix some of these sticks, though there will have been data loss due to the corruption. If fsck shows errors but cannot fix them, it's time to reformat the device, and no data will be recoverable. Any stick which has been given a drive designation, and been formatted, and still doesn't work properly is probably broken beyond repair. -- Joe
