"dead" USBs

As a serial OS tester and otherwise someone who messes around with hardware and software I don't understand, I often end up with "dead" USBs, or USBs that don't respond to attempts at mounting (oh, I say!) image burning, and so on. Is there anything that can be done to bring these (sometimes pricey) bits of metal back to life? In most instances I have no idea what has been done to fiddle the life out of my little friends... I would appreciate a forum member transfering them the gift of life, if it is within their discretionary powers.

Re: "dead" USBs

Just use gparted and try rebuilding the partition table and/or formatting to ntfs first.

Re: "dead" USBs

The Sandisks with the proprietary crap - it is one of the few things I have seen that you cannot remove via linux - only been sucessful via Windoze. 

Gparted works well. 

I did take a flaky usb stick once and convert to ext2 (no journaling). I have a couple like that.  One 32 gb usb stick for an eeebox as another "hard drive" Nice for keeping owners, time stamps, etc when I could not use unison between machines (testing vs. stable) and sneaker netted my sync with it.  Also if lost it has a security via minor obscurity to the "win" crowd.

Re: "dead" USBs

When mine 'go dead' I zero them out using dd, & then create a new partition table with fdisk, & finally reformat them.

Re: "dead" USBs

I mean the kind of USBs that don't even appear to mount anymore - ones that don't show up in gparted, even, or close it down with an error. I suppose what might be useful would be a list of command line diagnostic tools for usbs/hard drives. I'll have a hunt around.

Having had an NTFS reformatted USB flash drive drive go permanently into READ-ONLY mode (with dozens of online solutions that did not work), I highly recommend NOT formatting to NTFS.

Re: "dead" USBs

Hey Crow, did you find anything usefull ?

   I have a kingston data traveller se9.  It is about six months old and has been used as a ubuntu installer.  So I thought I would clean it by writing zeros like this:
# dd if=/dev/zero of=/dev/sdb bs=4M


   I should be in the face-palm thread.
   Now it does not show up in gparted or fdisk.  After I insert it dmesg says this:

[ 5749.860067] usb 1-3: new high speed USB device using ehci_hcd and address 4
[ 5750.184049] usb 3-1: new full speed USB device using uhci_hcd and address 2
[ 5750.304018] usb 3-1: device descriptor read/64, error -71
[ 5750.932024] usb 3-1: device not accepting address 2, error -71
[ 5751.044032] usb 3-1: new full speed USB device using uhci_hcd and address 3

[ 5751.388039] usb 3-1: device descriptor read/64, error -71
[ 5751.604039] usb 3-1: new full speed USB device using uhci_hcd and address 4
[ 5752.012018] usb 3-1: device not accepting address 4, error -71
[ 5752.124026] usb 3-1: new full speed USB device using uhci_hcd and address 5
[ 5752.532021] usb 3-1: device not accepting address 5, error -71
[ 5752.532057] hub 3-0:1.0: unable to enumerate USB device on port 1

   All I can find on google is some people who might have solved this problem with a windoze only HP rescue tool.
   Does anyone have any explanation for this ?
