Ubuntu Problem with damaged hard drive during bootup

Hello,

I have a problem with the hard drive connected to my setup. When I connect the HDD which is damaged, and try to bring up my system, I get some error messages continuously on my console saying

Code:
ata2.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 frozen
ata2.01: failed command: READ DMA
ata2.01: cmd c8/00:08:00:00:00/00:00:00:00:00/f0 tag 0 dma 4096 in
         res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata2.01: status: { DRDY }
ata2.00: SRST failed (errno=-19)

After some time, the system boots up well. Whenever I try to execute some command related to HDD, it is struck.

How can I avoid the delay that is being taken initially during bootup?

Is there any way in the driver code where we can say kernel not to probe for the HDD if it is not able to recognize it well? Please help me...

Thanks in advance...

Regards,
Sai

You should remove the faulty drive.

You haven't told us which OS you use, but from the log i guess it is some Linux. (We shouldn't have to guess at all, so please describe always your environment.)

If so, the part probing your hardware is called "udev" and it is rule-based. Basically it scans the system permanently for (new) hardware and then executes some rule-based methods to create "devices" (=respective entries in the "/dev" hierarchy) for newly found hardware. This thing not only managed your harddisks, but also, if you are to put in (or remove) an USB stick, for instance. I suggest you read carefully the man page for "udev" to understand how it works and how certain devices (disks among them) can be "blacklisted" from probing.

If this still leaves questions feel free to ask again.

I hope this helps.

Hi Bakunin,

Thanks for your reply. I'm working in Linux environment.

I just wanted to explain more about the problem.

The system is still in the initial state when the delay is considered. I mean, it did not proceed till creating device nodes and all that stuff. Initially when the kernel is checking whether all the devices attached are fine, when it finds the damaged HDD, it is struck. It goes on checking and finally after some time, it reboots and then goes ahead bringing up the system.

I was asking how can we avoid the initial delay when kernel is probing for the damaged HDD?

Thanks and Regards,
Sai.

This is a similar process like "udev", but controlled via "GRUB". You should research the "GRUB" (or "GRUB2", depending on which Linux system you use) documentation how to exempt a certain drive from being scanned.

I hope this helps.
