          | Hallo, 
 I was trying to install Debian on a usb stick,
 with unetbootin.
 It didn't worked,
 and I repartitioned the stick using gparted.
 Gparted gave an error,
 and now this pen drive is behaving strange!
 
 kde mounts the usb and reads some files in it,
 while gparted says there's unallocated space.
 If I run fdisk, it says 'no partition is defined yet !'
 
 Here' s what fdisk says:
 
 
       Code: 
Disk /dev/sdb: 8022 MB, 8022654976 bytes
247 heads, 62 sectors/track, 1023 cylinders, total 15669248 sectors
 Units = sectors of 1 * 512 = 512 bytes
 Sector size (logical/physical): 512 bytes / 512 bytes
 I/O size (minimum/optimal): 512 bytes / 512 bytes
 Disk identifier: 0x0005b3c6
 
 Device Boot      Start         End      Blocks   Id  System
 
 
 Does anyone can help?

          | Presuming you don't care about what is on the stick now (if you do then use anything you can to access it and get the stuff off it) then just wipe the start of the stick and start again.   A command like:       Code: 
dd if=/dev/zero of=/dev/sdX bs=1M count=1
should do it (replace /dev/sdX with the device name for your usb stick, above you have /dev/sdb but you should check using dmesg or some other method this is still correct before blindly trying it). |

          | Here it' s done: 
 
 
       Quote: 
root@aptosidbox:/home/maurizio# dd if=/dev/zero of=/dev/sdb bs=1M count=1
1+0 record dentro
 1+0 record fuori
 1048576 byte (1,0 MB) copiati, 0,00875586 s, 120 MB/s
 
 
 Now when I put the stick even kde is not recognizing it.
 is it fine to partition the stick?

          | Yes, now you should be able to partition it as usual. |

          | Yes I did it now seems everything allright. 
 Gparted created another partitioning table,
 and then partitioned again.
 
 Thank you a lot,
 if anything similar will happen in the future I will know how to do it!
