Hey all, first off, I am _very_ aware that this is a painfully-basic
question, but this has been a rough week, so please bear with me...<br>
<br>
I've been searching for this info for a while now, but my
very-tired brain doesn't appear to be able to format the search
terms appropriately. What I'm wanting to do is to confirm that a
defined disk (/dev/sdb in this case) is essentially "a raw
partition" & doesn't have any data on it. If I can confirm
that, then I can create the needed partitions/filesystems & turn
it over to the customer. The 'fdisk' utility shows me this:<br>
<br>
<font size="2" face="Calibri"><span style="font-size:11pt">
<div><font color="#002060">Disk /dev/sdb: 214.7 GB, 214748364800
bytes</font></div>
<div><font color="#002060">255 heads, 63 sectors/track, 26108
cylinders</font></div>
<div><font color="#002060">Units = cylinders of 16065 * 512 =
8225280 bytes</font></div>
<div><font color="#002060">Sector size (logical/physical): 512
bytes / 512 bytes</font></div>
<div><font color="#002060">I/O size (minimum/optimal): 512 bytes
/ 512 bytes</font></div>
<div><font color="#002060">Disk identifier: 0x00000000</font></div>
</span></font><br>
Now I can tell that it doesn't contain any partitions on it (i.e.
sdb1, sdb2, etc.), but I just can't seem to remember how to confirm
that it isn't formatted as a single big partition. I'd be grateful
if someone could refresh my memory on this...<br>
<br>
Thanks,<br>
<br>
T.<br>
