The "invalid media type" error message indicates corruption of the BPB (BIOS
boot block, found in the extended BOOT SECTOR (usually sectors 63 to 68) and
usually not the partition table. Yet there is a possibility that an erratic
write to the MBR wrote to the partition table and the pointer to the boot sector
is pointing elsewhere, which results in the same "invalid media type" message.
I have seen both errors to occur on drive I fixed. A boot virus is also a
possibility, although remote (boot viruses do not exist anymore in the wild, and
the only possibility to catch one now is by attempting to boot of an infected
very old floppy).

Try RESQDISK (see my signature) to assess the problem.

Before fixing the wrong thing you need first to resolve which of the above is
the cause to the problem.
