Clicking SCSI disks

I have a number of old (2000-era) DEC StorageWorks disks that fail to mount under VMS. They report MEDIUM OFFLINE. They power up in a similar way to other disks that do work, but they persistently click ina? "something isn't right" manner. I've tried reorienting some of the disks to see if that makes any difference, and for the ones I've tried, it didn't help. I've read about the "freezer" trick, but mostly I've seen negative opinions. However, those opinions mostly come from data recovery specialists! So I thought I'd tap the wisdom of the list. Is there any way that people have used to successfully recover data from RZ28, RZ29 disks (which all worked in 2003 :-))? Has anyone tried freezing a double bagged drive? Was it successful? If so, how long did you freeze it for? These disks are in StorageWorks containers ... should I remove them before freezing? Antonio -- Antonio Carlini antonio at acarlini.com
