Very Interesting and most informative Dan, and thank you. Carefully reading between the lines of several hits also explains why I stopped having major failures of amanda, the backup software, when I replaced a 1Tbyte seagate with a 240 gig series 860 samsung SSD, used as a holding disk while amanda is collecting its data to be written to tape w/o shoeshining the tape while at the same time cutting the time to do a 20 gig backup from 3 or 4 hours, to 20 minutes. This post is also being sent to the amanda-users list to alert the users who are currently being affected by this and not finding a definitive answer. Bottom line for amanda users is, do not use todays spinniing rust drives as holding disks. They are simply not trustworthy for short term buffer storage. Symptoms are reported to the user as crc errors in the holding disk. That particular DiskList Entry is then repeated until a good crc is obtained. But that also leaves the bad crc data left on the holding disk eventually using up its capacity without manual intervention to clean up the mess. A genuine PITA for us, and leaves the drive makers in an unfavorable, bad dog, no biscuit light.
