Specific Master and Slave HDD problem

Hey guys, I don't really know if this is a hardware of software problem, but i'll just post it here and hopefully I get an answer.

Anyways...


So a friend of mine got a new computer today since his old computer was giving him a weird error (lsass.exe error - Unable to locate component") that wouldn't let him do anything to his PC, and gave him blank screens. So he just decided to just use the old HDD as a slave and the new one as a master.

Now, he owns a construction company and he uses the program called "Quickbooks" for payroll and etc.
Well, we made the old HDD to a slave, install QuickBooks on the new HDD, and everything's all good.

Well, we came up on the biggest problem, which would be on QuickBooks.
He needs to be able to reopen his QuickBooks that was on his old HDD that had all the employee files on it with the PayRoll and whatever else he keeps in there.
We open up the freshly installed QuickBooks, try to search for his old Company File and nothing comes up.
On his old computer, when he turned on QuickBooks, it would go directly to the Company File, but on the new one, we can't find his company file.

So my question would be is that...how can I find his old QuickBooks data in the slave drive? We searched every folder in QuickBooks and nothing came up.


Now, I was thinking of maybe finding a fix for the "lsass.exe" error while his old HDD is on slave, then when I find the solution to the problem, i'll make the slave into the master and vice versa. Would this be something I should do?

If anyone could give me any feedback on either ones, please do so.

Thanks for your time.

 

I fed the "lsass.exe error - Unable to locate component" into google, got a few pages which suggested it could be a boot sector virus, I don't know a great deal about viruses in general, but there's a chance that it could spread to your new HDD if you're not careful (assuming you do have a virus). You could do virus scans of the old HDD, and if something comes up, head on down the the malware forum (in fact the stickies in the malware forum would be good to follow for finding viruses). I don't know how good a boot sector virus is at hiding though, you should google about it, the pages you can find on the net will explain it much better than I can.

You could do the bog standard get out: set your old drive to master, and do a repair install of windows (use the recovery CDs that came with your PC). This should repair the windows files without removing any other data, but I make no guarantees.

 

Hmm, i'm trying to stay clear from the Windows Repair at the moment because I might end up doin something stupid and lose everything, so i'll try some other options.

I have found some solutions, such as doing a virus scan on the slaved HDD, but also, I want to do a "sfc /scannow" on the slaved HDD...but how do I do that?
