2TB wraparound Intel storage matrix driver fault.
Posted: 27 Dec 2014, 22:16
Hello,
I'm writing here for hope that someone can help me restore my partition to working order.
After finding a thread http://hardforum.com/showpost.php?p=103 ... ostcount=4 regarding the corruption of disks after writing more than 2 TB I realized this must be my problem. Initially, I posted about recovery regarding a drive that went raw 3 months or so ago on here, and chalked it up to a bad drive / earthquake. After replacing that drive, and copying data to it, the drive corrupted again in the same fashion. Looking at the disk with WinHex, I can see after a set amount of sectors there is nothing but zeros. Meaning that there is no data, which cemented the fact that the issue i'm facing is the 2TB limit wraparound bug.
Basically, after writing 2 TB, driver doesn't know how to address further, so it starts writing over the start of the drive at which point it writes over the partition information or MFT. By doing this, the drive shows up in windows as RAW but partitioned correctly.
When i try to recover the MFT via test disk it does not work and claims that both the mirror and the main MFT are corrupt. I was able to see the MFT files in WinHex, and extracted them to another disk (i do not know if these are the original or even good ones, as they just showed up under a directory in winhex when exploring the disk)
What I would like to know is if there is any way I can recover or manually insert the MFT files again so that the disk recognizes where the files start and stop so I can recover the disk with out brute force searching for indicators of files with various apps like NTFS getdataback ect.
The primary boot sector was showing inconsistent data, but that is fine because this is not a bootable disk it was a backup 4TB disk in my home sever.
I have 3 of these 4TB disks currently and they were all formatted in the same way.
