[ERROR:c03a001d] VirtualDiskAPI::CreateFormattedDisk failed to create vhd(x) RRS feed

  • Question

  • I’m trying to setup FSLogix for a customer using an existing share used for roaming profiles and am getting this message in the log file. The folder creates in the share and I can see the .vhd file show up, then disappear almost immediately.

    Has anyone seen this or is there any documentation documentation that gives the technical specs of the share in relation to the error below, i.e. sector size, etc?

    [ERROR:c03a001d]   VirtualDiskAPI::CreateFormattedDisk failed to create vhd(x): \\serverr\share\O365Container\username_S-1-5-21-302605577-1933724700-5522801-44638\ODFC_username.vhd (The sector size of the physical disk on which the virtual disk resides is not supported.)

    Thanks.

  • According to the FSLogix documentation (I'd link it here, but my account isn't allowed to post links), sector size "currently can only be 512 (0x200) or 4096 (0x1000)". I've never come across a hard drive/SSD with sector sizes different from that-- can you confirm that this matches the properties of the physical disks hosting the file share?

  • What is currently hosting your roaming profile share?

    Is this on Windows 7 or 2k8R2?  There are some Windows limitations around VHD sector sizes needing to match the sector sizes of the storage that they are placed on until Windows 8.1 I believe.
