USB Drives won't mount correctly

[LordRatner]

Very confused.

I've formatted the USB thumb drive in NTFS and FAT32. Only one file on it. Each time I mount it (and I've tried on two different PVE servers) the drive gives me this warning first:

mount: /mnt/usb-drive: WARNING: source write-protected, mounted read-only.

Then, after about 10 seconds, the mount point shows what appears to be a PVE boot drive. There are no other devices plugged in.

root@node2:/mnt/usb-drive# fdisk -l

I've tried different USB drives, rebooting, etc. What on earth is going on?

how did you format it? the message about read-only mount happens when there is a filesystem that cannot be written

I tried exfat, fat32, and ntfs.

But I also tried it on a non-proxmox Linux system, and got the same result. Strangely the drive works perfectly on windows, but it has to be a bum drive.

I tried another drive and it worked, so I either messed up the first time I tried a second drive, or I stupidly grabbed the same one.

Either way, thanks!
