Hello,
I cannot access any resources on my external eSATA hard drive when creating a VM in Hyper-V in Windows 8. This includes booting ISOs, making or using VHDs, etc. I receive the error "Hyper-V Virtual Machine Management service account does not have permission required to open attachment 'D:\<file location>'. Error: General access denied error. (0x80070005)". There are a few other questions on the forums about this but they've been solved somehow or forgotten about.
I'm curious if anyone else has encountered this and solved the issue. I've attempted troubleshooting this issue half a dozen times over the past month. A number of employees at my company are dealing with it, all which have very similar laptop models. The similar characteristics seem to be:
- Windows 8 / 2012
- Solid State Drive for the system drive (which is why it's always dealing with the larger external drive)
- Dell e6420 laptop or similar model
- Drivers up-to-date according to Dell but still warnings in devmgmt for (at least) "Mass Storage Controller" and "Unknown Device"
This issue did not occur with the same configuration on Windows 7. It does not occur on previous generations of Dell laptops or on dissimilar models. VMs run just fine on the system drive.
Here are some of the tactics I've tried already:
- Setting permissions to Full Control for "Everyone" and the specific Hyper-V accounts in the UI and through icacls
- Complete reinstallation of operating system
- Firmware and driver updates even if they seemed unnecessary
- Removal of BitLocker from both drives and then again after re-encryption
Thanks in advance for any help... even if you're just pointing me in a general direction.
