Change the default Azure temporary disk letter
Each Azure virtual machine comes by default with a Free and temporary drive, that is mounted in 'D:'
We all whish that Microsoft gives us the possibility to choose the letter of this temporary drive before deploying the VM.
Why ? Becasue the D: drive is the most used letter for data disks. This is a huge issue when migrating workloads from on-prem to Azure, and this is a real limitation.
I know there is a workaround to change the letter, but in case of unplanned fail over or host change, the temporary drive will be assigned the 'D:' drive, and it will cause service interruptions and issues.
Please, think about it. Great team you are!!
Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature list and also gives us insight into the potential impact of implementing the suggested feature
Having this as a setting we can control and specify on deployment, through the portal, template or powershell etc, it would be really helpful.
It's fast becoming the most time consuming task for us whilst deploying test machines for our migration.

Allow to specify a drive letter for the temporary storage in Azure Template
How about changing it to A or B. Unless someone is virtualizing their floppy disks that would never clash with anyone.
Yes, this feature should be available,, see:
Thanks in advance!

We have (standard) process of installing/running/backing up/recovering applications on temporary disk with backup/restore through data disk (developed in AWS). We like to have the option of set the letter for the temporary disk when we create a Windows VM (the manually or even programmatically change the letter is tedious), and keep the same letter for temporary disk after stopping and starting the instance. (Currently, after stopping/starting, the next, alphabet order, available is assign to the new temporary disk).

Please can MS look at changing the D drive (temp disk) letter to another letter at build, as this is the most common data and program drive on client servers being migrated to Azure?

I think the correct solution to this is to create a mount point on the C drive for the page file. this allows the users to have full control of the disk drives and any changes made at the fabric layer don't impact the users.

Please add a setting so we can control what drive is used. When testing with a v2 VM if you change the temp storage drive to the first available drive letter it appears that it does not cause any issues when the VM is resized, still doing some more testing.
