Problem backing up Hyper-V vhd - Error [0x80070015] The devi

I am trying to set up backup of our virtualization host. Host have 2 SCSI Cheetah 15K drives, 136GB each, with assigned letters C (system) and D (VM HDD).
Daily backup task I created ( BA 5.4.8 ) is set up to backup both C and D, "Activate Hyper-V VSS Writer" is checked, all paths shown in details are checked in backup (none are in exclusions list). "Backup local system state" is checked as well.

Backup runs fine through C:\, yet it consistently fails on D:\, error log contains:

Error in backup of D:\WS2k8SBS1.vhd during read: Error [0x80070015] The device is not ready.

Could somebody point me to the right direction what might cause such problem ? Thanks.

To complete the question, following are the list of backup files and contents of BackupSpecs.xml. Interesting to note is that 246417cb-d258-11e1-ad20-806e6f6e6963.vhd which is probably a backup file of VHD file, consumes about 30GB. VHD is static 135GB.

Unfortunately suggested solution did not help.

I ensured Volume Shadow Copy service was running (and switched to automatic) before doing last backup. VSS is also enabled (only) for D:\ drive, although vhd takes 135GB out of 136GB of total disk space.

After backup completed (with an error), the Volume Shadow Copy service was not running ! This might mean it was switch off by a backup or it failed during the backup process.

I sent the diagnostics back.

Thanks.
