Advanced Control for SATA Drives

I have this new large drive that is sata controlled.  I put all my data on the drive (transferred from origional drive 1/2 its size) and got everything working, then used the old drive in another machine (after formatting it).  Now I used my computer for a while with everything ok.  I tried to speed things up and found a setting for the sata drive to used the Advanced Control (protocol?) on it.  When I booted, it apparently did something to my drive.  now, instead of 1TB of data, it shows the drive at 32mb size, and I am not able to access it.  What is a good recovery for my data, or at least some of it?

Change the settings back to the original ones. Also look for a 32GB Cap setting somewhere on the drive. Many IDE drives have a jumper for that so the disk will work on old boards with old BIOS. On SATA Drives this may have to be set via software.

If that doesn't help, Scan the disk using getdataback, and it'll show you all the recoverable data. To be able to recover the data register the software and you'll be able to copy the data off.

The partition changed from something like 943Gig to 32Meg.  Windows XP Disk Manager does not even see the additional space as unallocated.  I ran the only partition viewer that I have (Copy Commander) and it knows that the drive is much larger than the partition, but says that there are errors in the partition and disables all its tools.

I tried the tool you suggested.  I put it in the "fdisk for formatted" (to cause problem) mode, and set it loose.  When it began to scan for drives, it gets an error: Windows - Drive Not Ready  "Exception Processing Message C00000A3 Parameters 75b6bf9c 4 75b6bf9c 75b6bf9c"  and asks to cancel, try again, or continue.  I did nothing... I await your recommendation.

Actually, I tried to cancel, and the program went on anyway.. It got another error, but did return this information:
1st hard drive 373 GB (HD128:) - ST340063AS
2nd hard drive 466 GB (HD129:) - SAMSUNG HD501J
3rd hard drive 31.5 MB (HD130 - ST31000340AS    

The last should be the 1000 GB drive!

Try testing the drive in another PC, does it get properly recognized with the full capacity?

You could also look for a BIOS update for your mainboard. 1TB drives are pretty new and there may be many boards and BIOS's around that have problems recognizing such disks. Also make sure you are using high quality SATA cables.

The Drive HAD been working fine.. that is why I took the origional drive and used it in another system.  It was fine until I went into the BIOS and enabled the AHCI on the device..  I believe it did "something" that took my nice working drive, and put in a different partition or something.  Now I can't access my data and can only see the 32mb size.  I can't access it however.

The GetDataBack for NTFS says:
found drive 128, X, Geo (48641*244*63-781420655),LBA 7814(off the screen)
found drive 129, X, Geo (40801*255*63=976771055),  LBA 9767(off the screen)
found drive 130, X, Geo (64*16*63=64512), lba 64512, 31.5(off the screen)   <--- this one is WRONG!

Thanks Rindi, but I did not get any resolution that solved my problem.  I wound up trashing the drive because I could not get an answer that enabled me to recover.  If that means closing the question, than I suppose that is fine.

Thanks for checking.

I think I now start to understand what might have happenned. You have probably set the 32 cap setting on the drive via a software command. Whether that was done via the BIOS or in another manner I don't know. Look on the seagate site and download the tools they have there. With one or the other of those utilities you should probably be able to change the disk's settings back to normal. If that doesn't help get yourself a copy the UBCD, on which there are a lot of tools too, and with those you should be able to unset the 32GB cap.

The drive was only 32MB, not 32GB.  
I wound up accepting that all the data was lost and sent the drive back to Seagate for repair.  While it was out, I ordered an additional one so I could get back going again.  I installed the new one and ran for 2 weeks when the same thing happened again!  This time I held Seagate on the phone while we diagnosed the problem.  I had also replaced my mother board thinking that my SATA controller was bad, so I knew that was not the issue.  On the call, we discovered that the RAID drivers are better at accessing the drives than the IDE drivers (which only emulate an IDE drive).  When we changed to the raid drivers, even though the drive is not a raid, it was able to access all my data with no problem.  I was even able to switch the bios back to ide and it could access the drive.  (can't explain why)  But the seagate fellow said that I should leave it on the RAID drivers as it is a native control for the SATA drives.  I have been running in this configuration without problem for 2 weeks.
