hello friends
recently when I attached my sandisk USB to one of the port of my computer, the green icon of usb did appear in system tray but it didn't show in my computer. I went in device manager, my device was shown there but it has no letter it shows status as healthy (unknown partition).device shows online. I tried to rename it but when I right clicked no option was visible except delete partition and help. same device was working perfectly few days back. I dont no what is wrong now. please help friends. I use windows xp with SP 3.
more info- my USB is of 16 GB . but in device manager it is shown as 2 separate unknown partition. first 14.86 GB and second 50 MB. both are 100% free.

should I choose primary partition or extended partition while creating ne partition ?
ok since I had no patience I went ahead with primary partition.now the device is shown in my computer as new volume (J). is it ok ? because it never shown as 'new volume' before. I guess problem is solved.but I still want to hear from you. thanx friend.
