I have two Lexar Professional 600X 16GB compact flash cards that are
unusable. fdisk shows:
[robert@dell64] ~> fdisk /dev/da1
******* Working on device /dev/da1 *******
parameters extracted from in-core disklabel are:
cylinders=29 heads=64 sectors/track=32 (2048 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=29 heads=64 sectors/track=32 (2048 blks/cyl)
fdisk: invalid fdisk partition table found
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 32, size 59360 (28 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 28/ head 63/ sector 32
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
It shows only 28 MB instead of 16GB. I have tried to change the type
from 165 (FreeBSD) to msdosfs types 6 11 or 12 using fdisk -u and fdisk
-i and also "sade". I do not get and error but when finished it still
shows the same data.
I have tried to zero it out using " dd if=/dev/zero of=/dev/da1 bs=1m
and nothing changes. I have tried different block sizes and counts to
no avail.
Is there any way I can restore these CF cards to 16GB? Any help or
suggestions will be greatly appreciated.
TIA
Robert
