USB Ram Stick

[Julian Stacey]

Hi freebsd-scsi at freebsd.org
My new USB, 2 Gig Sony Memory stick seems to have failed.
Could I / FreeBSD have screwed the USB device command block ?
Or might it be that eg the USB chip works, but the RAM is blown ?
Any chance / ideas how to fix it with FreeBSD ?  or should I replace it fast ?
(I recall that eg real scsi disks can be set to eg 512 or 1K blocks,
& then need a reformat, & wondering what else I might try ?)

The rest of this mail lists what I did:
  On FreeBSD-6.0-RELEASE I took a friend's 2G stick containing the
  usual MBR with one partition allocated as aprox.  2 Gig of DOS
  file system, & read the entire raw stick onto hard disc.

  (I still have that image BTW, 2138177536 Apr  3 01:40 sony-stick-da0 ,
   but I dont care about the data, I care about the expensive stick!)
  
  I wrote the image back to my identical stick (with dd), it wouldn't continue
  writing after a while, (cant remember exact message).
  Now /dev/da0* is just da0 , no other entries.
  
  I've tried creating a new MBR with fdisk, but failed.
  
  Ive tried creating a raw BSD FS on whole stick, & failed.

  I've tried copying just the first 512 bytes of the 2G image & failed.
