looking for help on how to proceed.

I have a hackintosh system and i was trying to install Windows 8 with an EFI install. THere are several drives in my computer, so i (thought) i was careful to select the right drive each time i attemped an intsall. The install would fail each time at the step where it copies over the install files (right after you do the formatting). It would fail by being stuck at zero 0% for a long time, and then give some error (i did not write it down but it was just a code), that when i looked it up related to the drive being bad. I attempted the install several times with the same results each time. Finally, i disconnected all the drives but the target, and everything went fine. So i have no idea what that was all about, but it was fixed.

Here is the problem though. After that was all done and I booted back into OSX, one of my drives would not show up. When i opened up disk utility, the drive had 8 volumes all greyed out labeled [disk2s1, NO NAME, disk2s2, NO NAME, disk2s3, NO NAME. disk2s4, NO NAME] when you delete and then format a drive useing windows installer for EFI you get the following 4 volumes visible by OSX [disk2s1, NO NAME, disk2s2, UNTITLED] where 'untitled' is the system data partition.

anyway the point of all this is that the installer clearly did something to my drive. i am hoping to install the results of my scan to get some advice on the next steps.

Given that this was an OSX disk, it was formatted as one large 2TB volume as HFS plus, I think it was partitioned as EFI, but it could have been master boot record. I am not 100% sure.

here is the result right after the can completed. i dont know what this means:


here are the partitions that were found with the quick scan:

I am a bit paranoid at this point as to what i should do next. any advice would be greatly appreciated.

Best,

Have you lost the partition table or is the filesystem corrupted ? Without more information, I will be hard to help you...
Please also post the whole testdisk.log file content.

Well, that is partially the reason for the long introduction, to see if I am missing something in terms of what happened.

My best guess is that i just lost the partition table. I say this because the drive was working just fine before i attempted the Windows install. I think that the windows installer wiped out the table somehow.

With that said though, i am surprised by all of the partitions that showed up. Is that normal? As mentioned before this drive was formatted as one single large partition. Is there a way to confirm this with testDisk? I would be happy to do so if possible.

here is the log file:

testdisk.log.zip

log for 09/16/2015 - 2tb drive

(4.1 KiB) Downloaded 293 times

Please let me know if you have any more questions, or need any information. If there is anything I am not providing, it is only because i did not realize that it was relevant.

Thanks!

There is no trace of a single HFS+ partition using the whole disk.
As the disk has been repartionned and the partitions formated, if you really have some data to recover, you can always try PhotoRec 7.1-WIP on the whole disk. Note that you will need 2 TB to store the recovered files.

Is that why it is showing so many HFS partitions? The formatting of the MS partitions corrupted the HFS? What would happen if I "write" what it found? Or do a deeper search and then write?

Restoring files with PhotoRec will not recover the files with filenames, correct? my experience with recovery software is that this is typically the case. Problem right now is that I am not 100% sure what was on that drive. it was a backup drive that i rarely access. There were some important things on there, but i can not remember what... dang.
