Flash drive will not allow me to access, reformat, or label it. When I plugged it into my XP machine it tried to format it with windows media player and now on my Vista machine it won't allow me to do anything. Will I have to go back onto my XP machine and try to reformat it or is there any way to fix this problem through Vista?(which would be easier since my little brother fried the XP machine) Thank you. :)

Brief expert note tied to the thread: reported a Cruzer Micro 4GB that refuses access, labeling or formatting in Vista after an XP machine “tried to format” it. and pointed toward reformatting options, but before you wipe anything there are safer diagnostics and recovery-first steps to consider.

The behavior usually stems from either filesystem/partition-table corruption or a flash-controller/firmware failure that forces the stick read-only. Windows sometimes shows a generic “format the disk” prompt after an unsafe removal or after it cannot recognize the filesystem — that prompt is not a guaranteed fix. Non‑destructive checks that often clarify the condition are: try a different OS (boot a Linux Live USB) to see raw device info; make a bit‑for‑bit image of the stick before attempting repairs so you preserve recoverability; and run file‑recovery tools against the image (TestDisk/PhotoRec, Recuva) if files matter.

If data recovery isn’t needed, a vendor or dedicated USB low‑level formatter can sometimes restore a usable device. If the drive reports zero capacity, becomes permanently write‑protected, or refuses all format attempts, it is usually a hardware failure (controller or NAND) and is not reliably recoverable by software — in that case check SanDisk warranty/RMA or replace the drive. Avoid repeated destructive writes if you need recovery; create an image first.

Summary checklist:

  • Do not immediately format if you want files back.
  • Image the drive before repairs.
  • Try a different OS for lower‑level detection.
  • Use recovery tools on the image if needed.
  • If formats fail and capacity is wrong, assume hardware fault and pursue warranty/replacement.
