From: Yousuf Khan on 29 Mar 2010 23:00 Bought a dual-disk USB enclosure and a couple of 1.5TB drives to put into it. First of all, the enclosure has a built in concatenation feature. When using that, Windows and Linux both see it as an 800 GB drive, rather than a 3000 GB drive! So I put it back to regular mode, and we see two separate 1.5 TB drives again. Next I tried concatenating through Windows Disk Management. BTW, this is Windows 7 Ultimate Edition x64. When I use the Spanned Volume wizard, it gives the error message, "Operation is not supported by object". I then tried converting each disk from MBR partitions to the new GPT partitions, it accepted that. I then retried the Spanned Volume wizard, and the same message appeared. Then I tried converting them to Dynamic disks, but it showed the "Operation is not supported by object" message again. I think whatever the problem is, it's from this stage where it tries to convert to dynamic disks. So why isn't it accepting the conversion to dynamic disks? Yousuf Khan

Just guessing here, but do USB devices support spanning natively? See http://social.answers.microsoft.com/Forums/en-US/vistahardware/thread/534f4fa0-7a61-4a23-952f-e034e1137e03/

It has this habit of thinking it knows what you do and do not want but at the same time is far too stupid to pull it off. Incidentially the 800GB seems to be a problem with the enclosure, there is no limit (that I know of) at 39.5 bit adress length. Maybe give this pice of trash back? USB storage supports both SCSI 32 and SCSI 64 bit sector numbers. Arno -- Arno Wagner, Dr. sc. techn., Dipl.

This is going to be used as a backup device, for my other drives. It's going to be unplugged and/or unpowered most of the rest of the time. Yousuf Khan |
