RE: USB Installation - CurlyMo - 9th Mar, 2013 06:54 PM @Namith, what usb stick did you use? RE: USB Installation - namtih - 9th Mar, 2013 11:02 PM It's this one: http://www.amazon.de/Supertalent-Pico-C-Flash-Memory-USB-Stick/dp/B001BAW7P4 I will post a dd benchmark later as a unrar process is currently running. I will also test the startup time. (9th Mar, 2013 06:26 PM)rendez2k Wrote: Well, for me, its slower. Using a Class 4 SD Card and a Intergral USB 3 stick, it seems noticeably slower booting up. Trying a class 10 card now without USB. An USB 3 stick slower than a Class 4 card!? No way.

ICIDU - never heard it before and I find no products in the german Amazon store. But they seem to produce good sd cards. RE: USB Installation - CurlyMo - 10th Mar, 2013 02:00 AM http://www.icidu.com/en/secure-digital-hi-speed-4gb.html Please notice you get the exact one as in the picture. The newer models are less fast. RE: USB Installation - SolGarlic - 10th Mar, 2013 05:18 AM I just installed xbian root in the 2nd partition of a 2TB WD green HDD inside a USB2.0 box, and following the same procedure as CurlyMo I got: HDD Write: 31.6Mb/s HDD Read: 25.2Mb/s While with my SD (samsung class 4, 8gb) I had: SD Write: 22.5 Mb/s SD Read: 18.11 Mb/s The current boot time with the HDD is over 1 minute until I see the "Videos" in XBMC (with sickbeard, transmission and nzbget also starting). Meanwhile, the output of "df" is this: Terminal Filesystem 1K-blocks Used Available Use% Mounted on rootfs 7720408 1230528 6489880 16% / /dev/sda2 7720408 1230528 6489880 16% / tmpfs 12356 284 12072 3% /run tmpfs 5120 0 5120 0% /run/lock tmpfs 10240 0 10240 0% /dev /dev/sda2 1406530524 811816828 594713696 58% /media/usb0 /dev/sda1 1406530524 811816828 594713696 58% /media/usb0 tmpfs 24700 0 24700 0% /run/shm /dev/mmcblk0p1 34662 11127 23535 33% /boot Isn't there something wrong with both sda2 (my current root according to cmdline.txt) and sda1 being aparently mounted to the same spot (altough only sda1 files appear)?? RE: USB Installation - Richdotward - 22nd Mar, 2013 06:44 AM Hi Can anyone please help me. After months of getting corrupted SD cards I've decided to try and boot / run the pi from an old laptop HD inside a small USB caddy. I've followed the instructions on this topic and have a system booting from the HD. xbian@Raspberry ~ $ df Filesystem 1K-blocks Used Available Use% Mounted on rootfs 1864536 794676 1069860 43% / /dev/sda 1864536 794676 1069860 43% / tmpfs 38284 244 38040 1% /run tmpfs 5120 0 5120 0% /run/lock tmpfs 10240 0 10240 0% /dev /dev/sda 1864536 794676 1069860 43% /media/usb0 tmpfs 76560 0 76560 0% /run/shm /dev/mmcblk0p1 34662 10973 23689 32% /boot The problem is that my 60 Gb HD is showing as the same size as the orginal 2 GB SD card.

But I don't see a newer model on the ICIDU website? I'll go for the 8GB alternative, it's only €9 at an online shop or €10 at the local Mycom shop (NL). Thanks for the tip! EDIT: so I bought the 8GB ICIDU Class 10 and it is much slower ![]() Code: xbian@xbian ~ $ sudo hdparm -Tt /dev/mmcblk0p1 godammnn. RE: USB Installation - Fred - 7th Apr, 2013 02:00 AM I have also set up my Raspberry to boot from USB, it's a lot faster for me. I have some problems with booting, sometimes it seems it can't mount the root partition. Can someone help me with troubleshooting this, I don't know which log files I should look into. I have disabled the splash screen but it does not print any errors, it just stops printing lines. Furthermore I had noticed that the partition was mounted twice (because of usb automount). I worked around this by removing ext4 from the filesystems to automount in usbmount.conf (https://github.com/xbianonpi/xbian/blob/b13291dc6703ad9fce329a2c1e0462f230694a4f/etc/usbmount/usbmount.conf), because my root partition is ext4. This is probably not the right way to do this so I would like to get some advice about this too. RE: USB Installation - Fred - 28th Apr, 2013 09:39 PM This is the output of the bootscreen when the boot hangs. Can anyone make any sense of this?

Can anyone make any sense of this? are you using console=tty2? then fsck requires your attention (Y/N) and it's on the second screen. RE: USB Installation - Fred - 29th Apr, 2013 08:20 AM I have no idea what this tty is so I don't really know what you mean with that. I only use one screen, the tv (is it even possible to use multiple?), and the tv shows tty1 on the tv screen after a successful boot. |
