I've posted this question at many Web-Sites in the last week, but nobody can help me. For a view days I've created a Software Raid 5 (mdadm) under Ubuntu 7.10 32Bit Alternate with 4 x 233 GiB SATA II Hdds @ USB 2.0. After that I want to create a Truecrypt-Volume on this md-Device what not should be a problem. But the Process hangs after a view Minutes running and then whole System hangs. So I've pushed the Power-Button and the System writes something to the System-Hdd - but then nothing happens further. Then I have resetted the System. After next boot I've assembled the Raid 5 again what function without any problem. The System even wont to resync anything. After that I've build the Truecrypt-Volume on the whole md-Device without any Problem. Now my question: Is there any Methode to Test the integrity of die md-Device at low-level? Can I trust the Device? Best regards, Michael -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS. Alle Infos und kostenlose Anmeldung: http://www.gmx.net/de/go/freemail
