Hi all

How and from where i can know the Phycally attached hard disks which are crashed.(in which folder and file this information is stored).

Thanks and regards

There is no specific folder or file, in order to find out such info go to Applications > Utilities and start up either Disk Utility or Terminal and do what previous posters have mentioned. There you will find info about all mounted volumes. When you say volumes that have crashed how exactly do you mean? Can you no longer access the drive in question?

Well if it does not show up in Disk Utility or OS X does not ask you whether or not to initialise it at startup then the disk is probably broken. Disk Utility will show any drives it can recognise whether the data is corrupted or not. If it doesn't show up then you need to look at specialist software and possibly data recovery specialists.
Is this a SATA drive? Mounter internally or externally (if so what adpater are you using)?

What you probably want to do is open System Profiler. It will show you complete specs for the system, including all attached devices on all busses, whether they're mountable or not--if the controller in the device is working at all, it'll at least show up. Disk Utility will only show mounted/mountable storage volumes.

To open System Profiler, you can either just look in the Utilities folder, or go to "About This Mac" under the Apple menu, then click on the "More Info" button in the window that appears.

Never thought about it that way. As I understand (understood) it, if a disk is connected which is recognised but not readable OS X will ask you whether or not you want to initialise it. If it won't initialise then it is corrupted and in need of more serious TLC. I have OS X setup to mount all volumes on to the desktop and when I jimmy rigged my G5 and attached an old ATA drive to the DVD bus to test it it gave me the initialise message and the warning stop shaped sign.

From where the system profiler and disk utility get info about the hardDisks attached

hi all

you are right sir i can got these information through system profiler and can through disk utility. But from which internal mac structure these information can be found. From which file or structure or system function the system profiler and disk utility got the information about the hard disks attached to the system and what is the serial no and model no of hard disk attached to the system.

Thanks and regards
