unable to open /dev/sdc
But i get respond for hdc
You will not be able to write the partition table.
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklab
el
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
PLEASE

sdb: sdb4
As shown above, you can see sda and sdb. If you can't see sdc, then the 3rd harddisk is not detected. It could be caused by SCSI termination problem, check the jumper on the harddisks.
If you find hda or hdc, then the harddisk is an IDE/ATA harddisk, plugged to the IDE/ATA bus tape instead of SCSI. There should also be relevant info in dmesg for IDE/ATA.

Hello,
There is no jumper in disks. It's hotplug ind scsi disk.

This depends on the other hardware, it would have to support hotplugging, if you try that option on hardware which doesn't support hotplugging, you could damage something.

It support hotplugging, But i don't no how can i check the box (X) ok for removable in adaptec configuration.
Sorry, neither do I, as at the moment I don't have a similar configuration around on which I could try that.
ASKER
Thank you very much
thanks too.
The command "dmesg" should reveal the harddisks detected during bootup, and the assigned device name.
