ASYN-start unit request failed

I have a Seagate ST373307 LW SCSI drive on which Windows XP is installed dual booting with Windows Vista on another SCSI SeaGate Drive. While I was working Windows XP froze. On reboot I got the message from my SCSI bios Adaptec 39160 was "ASYN-start Unit Request failed" and I could not boot into Windows XP nor into Windows Vista. I put the hard drive into another PC which has SCSI but it also gave the same message. That particular computer runs only Windows Vista so the SeaGate Enterprise Diagnostic Tools do not work. The Ctrl & A SCSI utilities do not work on the disk either.The hard disk spins gets lighted up and gets hot but still does not work. Windows Vista detects it in Device Manager and says that it is working properly but obviously it is not working properly. In Disk Management the Logical Disk Manager says device is not ready.
Can the disk be salvaged? I really want to save time inconvenience and money.
Why did such an expensive hard drive failed was it because of heat because I have installed three SCSI hard drives side by side or was it due to any other reason. My IDE HDD are still intact or perhaps I do not use them so often.
I do have an image but it is a pretty that it was before changing the motherboard to Asus P6T Deluxe V2 (I wanted P6T Deluxe with SAS support but the vendor gave me the wrong mbo) with Acronis Echo Work Station I did manage to restore a truncated image but it was a herculean effort to restore Windows XP & Vista second time I may not be so lucky.

You can get the Acronis True Image Echo Workstation Universal Restore what will allow you to restore to a different hardware platform.

the only other option is to send the drive to data recovery center.
such as http://www.sfbayarealowcostdatarecovery.com/ they charge $129

It looks as if the Experts Exchange fraternity  are collectively of the view that nothing much can be done about the disk because none of them are commenting on it after ComputerTechie.
I myself was of opinion that I would have to get a replacement disk and even without the suggestion of ComputerTechie would have done the same. But he is more qualified to speak then me and his confirmation wiped off any lingering thoughts of a salvation of the disk.
I bought a Seagate ST373455 LW Hard disk  15000 rpm as the previous 10000  rpm was not available. Configured the SCSI ID and then used the Acronis True Image Workstation universal restore software which I have, to resurrect the image of Windows XP. This time I did not have to restore Windows Vista. With the restoration of Windows XP it automatically came. However Acronis Universal Restore is not all that sweet sailing as even after restoration audio (Creative Audigy) Video  and Intel Chip Utilitiy and other software for more devices had to be reinstalled.
But it did not take me a week to retore windows as it would have if I had not had the image.
SCSI hard drives are not really meant for home users or pure amateurs I wish to stress through these columns to any reader  that an image/backup is sina qua non or essential for any serious computer stuff. I felt like a professional adding a replacement disk  and restoring windows on it within a day.
In the end I would like to reward the expert who advised and confirmed to me as what to do
