Не ме питайте как се е стигнало до тук, не знам.
Флашката е 2GB Kingston, опитвам се да я форматирам, но твърдо отказва. Могат да се правят всякакви експерименти на нея, всяка идея е добре дошла

You will not be able to write the partition table.
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x1deb7f05.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
