Did I just set the slowest writing time record with dd?


I lost my better USB stick, so I had to use an older one to write in the latest-desktop.img

usbus2: 480Mbps High Speed USB v2.0
ugen2.5: <SMI Corporation USB DISK> at usbus2
umass0: <SMI Corporation USB DISK, class 0/0, rev 2.00/30.00, addr 5> on usbus2
da0: <SMI USB DISK 3000> Removable Direct Access SCSI device

dd if=latest-desktop.img of=/dev/da0 bs=1024 conv=noerror,sync
3317203968 bytes transferred in 9486.723351 secs (349668 bytes/sec)

9486 seconds=almost 3hours :slight_smile:


bs=1024 That’s doing 1K blocks, no? I typically do at least 1M blocks.


This [CORRUPT] made me drop to 1024, initially. Tho, I found out after 2+ hours that either way, 1024 or 1m, makes no diff. same [CORRUPT] output after dd was done. I waisted some time, so be it - lol

 gpart show /dev/da0
    =>      3  6478909  da0  GPT  (7.5G) [CORRUPT]
            3     1600    1  efi  (800K)
         1603      125    2  freebsd-boot  (63K)
         1728  6475136    3  freebsd-ufs  (3.1G)
      6476864     2048    4  freebsd-swap  (1.0M)

The corrupted USB stick booted TrueOS. Now, I’m fighting with UNSTABLE’s nvidia driver, wonder what’s next …?
