I recently got this credit/business-card shaped USB flash drive. In windows 7 it's recognized fine, after some drivers are automatically installed (without user interaction) once it's plugged-in.
In Ubuntu 13.04 all I can see in gparted is that the file system on the device is "unknown" and it also won't appear in Nautilus' device list (on the left panel).
When I ran this command:
sudo file -Ls /dev/sdb
that's what I got:
/dev/sdb: x86 boot sector; partition 1: ID=0xc, starthead 0, startsector 32, 7826656 sectors, extended partition table (last)\011, code offset 0x0
Edit - also, when running this:
sudo fdisk -l /dev/sdb
That's what I got:
Disk /dev/sdb: 4007 MB, 4007264256 bytes
230 heads, 63 sectors/track, 540 cylinders, total 7826688 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: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdb1 32 7826687 3913328 c W95 FAT32 (LBA)
Any ideas? (I'd rather not format it with Ubuntu because I'm afraid it might make the situation worse)
sudo blkid /dev/sdb1
, though; that will return a report on the basic contents of the single partition on the drive (its filesystem type, for instance).
