Microsoft,
Please take action on this. It is extremely hard to find external hard disk drives that are "BACKWARDS" compatible with your Windows Server Back Up application. The software will not recognize volumes larger than 2TB and the allocation unit sector size must be 512k. From Server 2008 and newer this issue MUST be addressed as backup volumes are increasing in size and I have been unable to find one hard drive manufacturer that makes drives that will meet both requirements any longer...
This is really poor considering all the attention your developers give to Server software.
Moving to 3rd party backup solutions that actually work in the TODAY!
Please do something!?!
