Seems that you have a situation here where you might be missing a few snapshots or the snapshot chain might be corrupted. you can power on the VM if you Change the PID (parent ID) value of SPSDEV01-000001.vmdk to CID ( child ID ) value of SPSDEV01.vmdk,
ie : The Child ID of the first vmdk becomes the Parent ID of the SPSDEV01-000001.vmdk. The following KB should be helpful in doing the same
Then point the SPSDEV01-000001.vmdk to VM and power it ON.It should power on. and if you see that the data is missing then you might be missing
a few more snapshots, find them and correct the chain, ie match it with its correct parent.
cheers.!!
