version 51ab816b505d1b745130562908d866915c836056 (clean) (release)

have 2 intel ssd's wanted set external storage on using apricorn usb/sata adapter.
used same process of formatting , mounting both drives.

1. attached drive (rpi sees sda in fdisk -l)
2. fdisk /dev/sda1, o, n, p, 1, d,d,d,c,w. (exits no error).
3. mkfs.vfat /dev/sda1
4. vim /etc/fstab "/dev/sda1 /var/multimedia vfat users,umask=1000,rw,auto 0 0"
5. reboot

upon rebooting see error sda1 not block device in logs.

, no sd* in fdisk -l.

dmesg shows drive connecting disconnecting in loop:

plug drive 1 mac , mounted automatically.
in osx re-partition drive , reformat exfat.

plug drive 1 in rpi2 , sda connect/disconnect loop.

ok maybe wrong drive 1.
try drive 2. re-flash sd card , repeat steps 1-5.
, connect/disconnect loop new drive.


lost. thing have not tried using 2nd sd card distro, working on now.

experience similar?

it may usb power issue, need quality psu 5v2a, if psu seperate usb cable ensure quality cable.

add config.txt following

code: select all

max_usb_current=1

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi

Smoothing Capacitor value?

hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what ...
