    SCSI Minolta scanner and Adaptec 2920c card problem

    I have a Minolta Scan Dual SCSI film scanner attached to an Adaptec 2920c PCI card, but I cannot get it working under FreeBSD after days of trying (13.1-RELEASE-p7, generic kernel). I have kept a dual boot option on the computer for obscure programs that will only run under Windows and so, after...

    Hi, I have an issue with Seagate ST10000NM0016 drives sporadically refusing to work. 8 of them are attached to a 9207-8i controller and assembled in a RAIDZ2. At unpredictable intervals, drives throw errors like (da6:mps2:0:45:0): SYNCHRONIZE CACHE(10). CDB: 35 00 00 00 00 00 00 00 00 00...

    Why were "block devices" dropped?

    I am a relative noob to the storage world in general and FreeBSD in particular. OF what I have been learning of late, I have become somewhat familiar with such concepts like disk queuing, IOPs, latencies and the likes I am also reading the classic 'The design and implementation of the FreeBSD...
