Internal HDD (WD30EZRX) is not accessible Access denied Windows 7 Pro
Hello everybody,
I have rebuilt my computer, and when I installed my "old" HDDs on the new motherboard and CPU, the freshly installed Windows 7 Pro would not recognise one of my internal HDDs (Western Digital 3TB Green WD30EZRX). I say "old" because the HDD is less than 6 months old, and I have used it sparingly (as a library - not OS, or other work).
CPU i7-4770K
Motherboard Gigabyte GA-Z87X-UD5
problem HDD: WD30EZRX Green
working HDD: WD40EZRX Blue
working SSD: Samsung Evo 840
I reinstalled Windows, all the mobo drivers, everything works, but I cannot access this one HDD. I tried different SATA ports, I even tried installing it in another computer (also a fresh Windows 7 Pro install) and I got the same error - with this HDD only.
I SHOULD NOTE that on the old system Windows 7 Ultimate (where it was working fine), I applied a security policy on this drive to prevent certain users from writing to it, and only allow them to read the drive. HOWEVER, I applied the same policy on my other HDD (WD40EZRX) which is being recognised just fine in the new Win7 Pro install. So I'm not sure if this has anything to do with it.
Whether it's a logical or hardware problem, I don't know. This is what I noted so far:
- The error message in Windows Explorer > My computer is: "F:\ is not accessible. Access is denied."
- The HDD shows in Device Manager and Windows insists "The device is working properly"
- in Disk Manager it looks fine and healthy
- ScanDisk (Error-Checking) utility in Windows and WD Data LifeGuard reported no errors (both could run on the HDD)
- Right Click and Proporties shows the used/free space ratio
- !!! In Disk Manager, if I right click on the drive, I cannot select "Make Partition Active" and although it shows the Primary partition of the drive to be healthy, it doesn't say it is active!!!
I tried to attach a few screen shots to this post.
(Edit: Apparently the "Make Partition Active" is only for partitions with a loader for an operating system, which is not the case for my drive - so the problem may lie elsewhere.)
Partition - Mark as Active

I'm a bit stuck, because I don't want to experiment too much with the partitions and risk messing up the MBR. And I am not sure which way to go.
I found a similar problem on the forum (albeit with some differences), and before I atempt to recover the data with Linux Puppy (as indicated in the thread below), I thought I'd ask if there is anything else I could do. Internal hard drives not accessible
Any suggestions would be greatly appreciated. Thank you very much in advance.
