1 I can't recall if I asked this before, but I am looking at a partition on a
2 USB stick which seems to have a FAT16 fs on it and in parted says:
3
4 ==================================================
5 Model: Crucial Gizmo! overdrive (scsi)
6 Disk /dev/sdb: 1023MB
7 Sector size (logical/physical): 512B/512B
8 Partition Table: loop
9
10 Number Start End Size File system Flags
11 1 0.00B 1023MB 1023MB fat16
12 ==================================================
13
14 What does "Partition Table: loop" mean?
15
16
17 fdisk -l is more confusing:
18 ==================================================
19 Disk /dev/sdb: 1022 MB, 1022623744 bytes
20 32 heads, 61 sectors/track, 1023 cylinders, total 1997312 sectors
21 Units = sectors of 1 * 512 = 512 bytes
22 Sector size (logical/physical): 512 bytes / 512 bytes
23 I/O size (minimum/optimal): 512 bytes / 512 bytes
24 Disk identifier: 0x69737369
25
26 This doesn't look like a partition table
27 Probably you selected the wrong device.
28
29 Device Boot Start End Blocks Id System
30 /dev/sdb1 ? 1869771365 2038460886 84344761 69 Unknown
31 /dev/sdb2 ? 1701519481 3571400945 934940732+ 73 Unknown
32 /dev/sdb3 ? 2573 2573 0 74 Unknown
33 /dev/sdb4 0 3435113471 1717556736 0 Empty
34
35 Partition table entries are not in disk order
36 ==================================================
37
38 What are the partitions shown as sdb1-4?
39
40 Also Id 73 and 74 are I think reserved Ids? Id 69 is I think Novell Netware
41 5+ (according to:
42 http://www.win.tue.nl/~aeb/partitions/partition_types-1.html) not FAT16.
43
44 I am not sure I understand what it is showing me.
45
46 BTW, cfdisk spews it out right from the start:
47 ==================================================
48 FATAL ERROR: Bad primary partition 1: Partition begins after end-of-disk
49 Press any key to exit cfdisk
50 ==================================================
51
52 So, does it have a partition table? How can you explain the fdisk output?
