Netserver LC3 Delayed write error

[Dr Owen Parry]

I know this has come up before but no previous message matches my case.

I have just added an 18.2 Gb hot swap drive to my Netserver, added it under NT, formatted it to NTFS, assigned drive letter all quite happily.

However, when I try and copy a group of files to it using windows Explorer from another drive on the same machine, I get the System Error : Lost Delayed-write etc message.

So this doesn't match the Microsoft Q on this (cluster servers or transfers across networks) and it isn't a rogue application that is acting up but a standard Windows function....

Any ideas ? (We have a machine on a remote site to which we added an identical disk without any problems at all)
