I have problems accessing my local shared directory if the disk size is 1 TB. To solve, I increase IRPStackSize to 18 as described in http://winhlp.com/node/40 and is successful. This problem does not exist on my other 80 GB disk.

My concerns are

* Is there a relation between IRPStackSize and hard disk size?

* What is the impact of increasing IRPStackSize? What is the recommended value?

See http://support.microsoft.com/kb/285089/en-us for a description of IRPStackSize. Its more a correlation between the file system driver and IRPStackSize.
Impact is low (36 bytes if you increase by 1), but the article mentions problems if the value is between 33 and 38.
