HDD CASE OS NOT FOUND, GOOD CHALLENGE

By Casemaker ·
Situation:Client.Training school. They have 12 computers running W98 connected by network to the instructor?s computer. They use removable HDD cases in all systems with floppy and DVD drives.
PROBLEM: Customer uses Disk Image by Powerquest to ghost these drives on a regular basis, her procedure is to clean out all the files and junk that the students may have created on one HDD and then ghost the remaining. She has done this with no problem since buying Disk image. On Thursday when she booted up one of the systems she received an error message ?operating system not found?. She then cleaned out one of the other systems and was going to ghost it to the system that had the error message. When she did this she received and error message ? the fat files are not identical and if she wanted to continue press cancel? she pressed cancel put the drives back in. The two machines produced error messages invalid system disk replace and press any key and operating system not found she tried it on another system with the same results.
DIAGNOSTICS: Tried booting with boot disk and tried fdisk and received error message no fixes disks found. From the dos prompt I found the c: drive and did dir but found no files. On one disk it had a fat 12-file system. The only way I could repartition and format the drive was to remove it from from the removable HDD tray and then it would find the disk and let me format and reload windows. When I finished and tried to put it back in the tray it said nooperating system found. I have swapped the HDD tray with several known good ones to no avail. I had to follow this procedure with all four and run them without the HDD trays. During windows install I received a message about the drive being compressed as well as not having enough disk space. I would hit escape and the install would be successful. I cannot get them to boot inside the HDD case only outside.

HDD CASE OS NOT FOUND, GOOD CHALLENGE

It almost sounds like a virus affecting the system BIOS and/or HDD controller. Have you done a scan? You indicated that this spread when you started ghosting hard drives.

In Windows, any problems in Device Mgr? Exclamation marks on Hard Disk Controllers or CD-ROM? Is the CD-ROM even listed there?

Boot to Windows, then go to DOS window. Run CHKDSK. Look for 'total bytes memory'. It should be 655,360, regardless of how much physical memory is in the machine. Any other number, or problems in Device Mgr as mentioned above are common indicators of a virus. That's where my money is here.

Good luck with this one.

Almost sounds like a jumper has fallen off the HD . Check that it is being recognised in the Bios & jumpered correctly .

I had a double listing in DM. I have not done a scan for viruses. If it is a virus, why would it let me fdisk and format the HDD after removing it from the removable HDD tray and not when it was in it. It would fdisk and format once I connected directly with the IDE cable on PRI 1.

The CD ROM would not be found using the boot disk it would be recognized after taking it out of the HDD removable case.

Have you tried contacting Powerquest about this issue? With the number of computers you're relying on, I'd be sure to try that route also....

Good luck.

Sounds like a virus to me as well. Run fdisk again, this time using the command fdisk /mbr . I have seen this problem in the past and this is the only way to fix it. I have had times when I had to renew the Master Boot Record a few times before ittook, hope this helps.
