Thank you Vishal, I guess I was expecting a more-specific output.
Much appreciated.<br>

/dev/sdb' returned no output, so presumably it contains
no filesystem. <i>However</i>, the output of 'file -s
/dev/sdb' shows the following:<br>
<br>
/dev/sdb: data<br>
<br>
...which is just ambiguous enough to make me wonder.
Does anyone have any feedback on that??<br>

Thanks again all,<br>

<div bgcolor="#FFFFFF"
text="#000000"> 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>
