Can't format it either. If you mount it with the sync option, later kernels will destroy it fairly quickly (there was a thread on this a few months back). It is possible that the FAT was about to die when you lent the stick out and the failure when Windows was let loose at it is purely a coincidence. I had a stick fail like this and even 'cfdisk -z', which ignores any existing partition table, couldn't handle it. -- Neil Bothwick Some people are born mediocre, some people achieve mediocrity, and some people have mediocrity thrust upon them. - Joseph Heller, Catch-22 signature.asc Description: PGP signature

Hi, does the stick have a write-protect switch? Mine has - and AFAIR most sticks too. Maybe he switched it? -- gentoo-user@gentoo.org mailing list

Might even want to try it with *gasp - I can't believe I'm saying this* windows. I did manage to fry a USB port on my motherboard one night. It was dark, I was plugging a memory stick in the front connector, kind of a awkward reach. Tried to insert it upside down. Apparently the stick's case shorted the port's pins. Soft crack sound. Whiff of burnt electronics. Sigh. Point is that the USB ports are not fool proof. - Roy -- gentoo-user@gentoo.org mailing list

I lent my USB stick to a guy for a job the other day. Apparently his Win98 box wanted to install drivers for it to work, so he pulled it before Wintendo (anything 2000) could get to doing its stuff.Now I get SuicidalPuppy martoni # mount /mnt/usb/mount: block device /dev/sda is write-protected, mounting read-onlymount: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or soAnd SuicidalPuppy martoni # dmesg |tail...FAT: bogus logical sector size 255VFS: Can't find a valid FAT filesystem on dev sda. FAT: bogus logical sector size 255VFS: Can't find a valid FAT filesystem on dev sda.Googling a bit I found a few ideas how to get the USB-thingie up again.Like:SuicidalPuppy martoni # hdparm -r0 /dev/sda /dev/sda:setting readonly to 0 (off)readonly = 0 (off)SuicidalPuppy martoni # parted /dev/sdaWarning: Unable to open /dev/sda read-write (Read-only file system). /dev/sda has beenopened read-only.
