Hi there, i didnt know if anyone can help. im trying to recover some data from a dying/dead NTFS usb stick for a friend.
If entered into an MS machine it just gives the option to format, ive tried repairing it via chkdsk /f but it comes up with "*Cannot open volume for direct access".*  I tried it on my linux machine and no mountable devices show, sudo fdisk -l shows only my current disks.  I have tried sudo ntfsfix /dev/sdb and i get:

Mounting volume... Error reading bootsector: Input/output error.
Failed to startup volume: Input/output error.

Volume is corrupt. You should run chkdsk.

Obviously chkdsk yields me nothing.

The drive is showing up via lsusb as:
Bus 001 Device 004: ID 1516:8628 CompUSA 128M Pen Drive

but in photorec it comes up as:
Disk /dev/sdb - 2199 GB / 2048 GiB (RO) - SKYMEDI USB Drive

Yet it is an 8gig (HP <<not that that means much)

Dmesg:

Any ideas on where to go now? The data on it is pretty important, ive just preeched the importance of backing up but as always its too late for that

Great if any of you guys can help, if not, dont worry.

Are you absolutely sure this drive is faulty? I apologise for potentially casting aspersions on your friend but, these are the same sort of messages that I get with my encrypted pen drives that have been encrypted with Truecrypt, if they are mounted and someone attempts to read them without it.
