Close, but:
Code:
rhino# dd if=/devices/pci@1e,600000/ide@d/dad@1,0 bs=1 skip=0 count=1024
read: Is a directory
0+0 records in
0+0 records out

rhino# ls -la /devices/pci@1e,600000/ide@d/dad@1,0
total 4
drwxr-xr-x   2 root     sys          512 Dec 18  2006 .
drwxr-xr-x   5 root     sys          512 Dec 18  2006 ..

You onlt chose the path containing the device, you need to use the full path to the actual device.

Go on give me a hint Smilie what would be the full path of the device? I thought that (/devices/pci@1e,600000/ide@d/dad@1,0) was it...

Code:
rhino# ls -l /dev/dsk/c0t1d0s0
lrwxrwxrwx 1 root root 43 Dec 6 2006 /dev/dsk/c0t1d0s0 -> ../../devices/pci@1e,600000/ide@d/dad@1,0:a

rhino# dd if=/devices/pci@1e,600000/ide@d/dad@1,0:a bs=1 skip=0 count=1024 | od -x
dd: /devices/pci@1e,600000/ide@d/dad@1,0:a: open: I/O error
0000000
rhino#

I still get an error accessing this HDD if there is no label on it. Unfortunately the HDD I am trying to analyse has data where Solaris wants to write this label...

Any more ideas anyone?

Please try to switch the "bs" and "count" values like:

dd if=<your device> of=<outputfile> bs=1024 count=1

perhaps this was the issue.

I have an IDE HDD in my Sun Blade and would like to read it (using C). It appears on the system and with the format command shows up as c0t1d0.

I use the dd command to read the disk as such:

rhino# dd if=/dev/dsk/c0t1d0s0 bs=1 skip=0 count=1024
dd: /dev/dsk/c0t1d0s0: open: I/O error
rhino# dd if=/dev/dsk/c0t1d0s2 bs=1 skip=0 count=1024
dd: /dev/dsk/c0t1d0s2: open: I/O error

but as you can see I get an error.

How do I read a raw, unformatted, non-Solaris disk in my Solaris box?

Any ideas appreciated...

Nice try Smilie

Although it looks like a dd error... it is not. The error is accessing the device via the handle... The Solaris box can not read HDD that has no LABEL it can identify (i.e. a Sun 'format' label)..
