BUT what if, if the new drive i'm adding is failing while doing the remove/delete operation? this is what i'm running into right now. a brand new disk which has an upcounting raw error rate. but there is no option to cancel an delete/remove operation. atm it isnt a problem for me. i hope to complete the operation successfully and replace the failingdrive afterwards. please consider to add an option to exit/cancel an delete/remove operation like in replace/scrub/... thx! sash --- Mail & Cloud Made in Germany mit 3 GB Speicher! https://email.freenet.de/mail/Uebersicht?epid=e9900000450
