[Solved] External USB 3.0 drive not seen under /dev/sd*

Ok, thought this would be easy but for some reason I cant get arch to see the physical drive. Its a new Seagate 2TB external USB 3.0 drive. I connected it to a windows laptop and it was quickly recognized (ntfs). I then installed ntfs-3g but still cant see it. I then formatted it under windows as ext4, but its still not seen. I tried this with 2 arch PC's, both the same issue. I seen a few other posts and tried a few things like making sure the mod xhci_hcd was running. I have the latest updates on each system. fdisk -l does not show the device at all! I can see and boot to other USB devices fine just not this one, maybe since its USB3.0??
I noticed here, they talk about maybe USB3 is broke in the new kernels, after 3.10.2 maybe?
Similar issue: https://bbs.archlinux.org/viewtopic.php?id=126299
Possible bug: https://bugs.archlinux.org/task/36296
However, I would think that by now, this would have been fixed as USB3.0 is more common? Other than trying to find a OLD 3.10.2 kernel any other advice?

Awesome, THANKS!! Yes I got it to work following this and specifically Da_Coynul's post:
I was able to get my external drive working again by telling the usb-storage module to ignore uas for the device. Here is how to do it:
First, create a file named ignore_uas.conf in the /etc/modprobe.d directory containing the following*:
options usb-storage quirks=Vendor_ID:Product_ID:u
*(substitute your actual Vendor_ID and Product_ID obtained from the lsusb -v command).
Next, regenerate your inital ramdisk:
# mkinitcpio -p linux
Finally, reboot your computer.
Although this is not a solution to broken uas, at least it will let you use your drive as before hmm

Thanks everyone...Now I can see the drive, and will work on formatting it with XFS...

Seagate Backup Plus Slim External USB 3 Hard Drive Not Working with Mac Pro

Hi, I have just purchased a brand new Mac Pro. I have three 2 TB Seagate Backup Plus Slim External USB 3 hard drives that just don't jive with the new Mac Pro's. When the drive is connected, I cannot access the drive, read/write or even format. Finder completely locks up and the drive cannot even be force ejected. When I try to format, Disk Utility either spits out an error that the drive cannot be read, or simply locks up. This happens regardless of the OS on the Mac Pro. I am currently running 10.10.2
I have ruled out an issues with the drives, as I have tested all of them on a variety of systems and OS's, including Power Mac, Mac Book Pro, PC, OS 10.7, 10.8, 10.9 as well as on Windows. I have tried formatting in every file system including Mac OS Extended, Mac OS Extended (Journaled), NTFS and exFAT. ALL other systems have no issues with the drives. Apple has replaced my Mac Pro with a brand new one and the drives still behave the same way. Furthermore, I have tested the drives on three other Mac Pro's at work and they all reject the drives. So, on their own, there is nothing wrong with the Mac Pro, or the drives. However, the configuration of them together is wreaking havoc.
I have contacted Seagate, and this was their response:
The most recent version of the Backup Plus drives use the USB Attached SCSI (UAS) standard to increase transfer rates. It's possible that the drivers being used currently on your Mac Pro are having issues using this feature with the standard USB 3.0 drivers installed. I would recommend contacting Apple to check for any driver updates or see if they any suggestions for issues involving drives using UAS.
I have also started a case with Apple Support (Case # 755934373) and am waiting to hear back regarding Seagate's response. I've spent DAYS trying to troubleshoot this and am now at a complete loss. If anyone has any ideas, I'm all ears (or eyes in this case).
Thanks!

Hi danielsh6,
I recently bought the new Lacie Thunderbolt 2 D2 3TB and I had the same problem as you, i have a macbook pro early 2011, those support thunderbolt but many times there is a bug that doesn't let you connect any thunderbolt drives to your computer. The solution I found was installing this update:
Thunderbolt Firmware Update v1.0
Before doing this I would recommend you updating to mountain lion (not yosemite yet as there is still some glitches and more on preview's macbook pro's).
Hope this helped!

My External USB CD/DVD drive not working while BOOT-UP

I am using HP Pavillion dv6000 series notebook (dv6205us) with Windows Xp 32bit...Actually I have hardware problem...
Actually my internal CD/DVD drive is not working...and I am using External USB CD/DVD drive...its work with windows platform but it cannot detected while booting process...
When I check in BIOS, it doesn't shows "USB CD/DVD Drive" in list...its shows the following options
ATAPI CD/DVD ROM Drive
USB Floppy
USB Diskette on Key
USB Hard Drive
Notebook Hard Drive
Network Adapter
I tried all USB options but it dosen't work. So, please help me in troubleshooting this problem.
And also 1 question:
My system also not supporting 64bit program like Red Hat Enterprises Linux 6. So can you help me find out does my system support 64bit programs. My notebook specification as follows:
CPU: Intel Pentium T2060 @ 1.6GHz (Dual Core)
CPU Instructios: MMX, SSE (1,2,3)
RAM: 2GB
Looking for your quick response.
Thank You.

Where can I get the driver for my HP DE8A4L external USB CD/DVD drive?

Where can I get the driver for my HP DE8A4L external USB CD/DVD drive?
On the label it says, Model HSTNN-PD06-91
and
HP PN: 518819-001 Rev.B
I've had my Mini 110-1000 running our music system for a couple of years, no complaints. When I wanted a CD/DVD drive, I purchased a DE8A4L external USB drive directly from HP. It didn't come with a driver disc. When I plug it in, the USB subsystem does not enable it. Device Manager shows a yellow exclamation point, saying, "Windows cannot load the device driver for this hardware..." It is running Windows XP Home Edition SP3.
What gives with this device?

Following up on tactic 2) above, I upgraded the BIOS from version F07 to the latest version available on the HP download site, version F19. This went well, but unfortunately the system still does not recognize the device.
When I try to Device Manager, and select the DE8A4L DVD device, and try "search for a device driver", it says it cannot find a better match for the driver already installed.
This Mini 110-1000 only came with 1 Gb RAM, and Windows XP Home. Is one of these a critical limitation for running an external USB DVD drive?

Arch: Install to & run from External USB Hard Disk Drive (HDD)

I wanted to play with ArchLinux 2009.02, but replacing the existing Debian-Lenny on the laptop's HDD wasn't an option. So I experimented with installing Arch on an external USB Hard Disk Drive.
I have tried to make this "newbie-friendly", so I hope the more experienced will forgive the detail.
Materials:
Three year old Dell Inspiron 6000
CPU = 2.0 GHz Pentium
RAM = 2.0 GB
Internal HDD = 80 GB
Internal CD/DVD R/RW
External USB HDD = Freecom FHD-2 Pro 80 GB
Archlinux 2009.02 install CD
Steps to install:
1. I put the Archlinux install CD in the drive and connected the external 80 GB HDD in the USB port.
2. When the Dell laptop was booted, I pressed F2 to enter the BIOS setup. I edited the boot sequence to the following:
Internal CD/DVD
External USB device
Internal HDD
On the Dell, you can also press F12 to select the preferred boot device for that boot.
3. I started the laptop and the Archlinux installation menu came up and I proceeded with installation following the "Official Arch Linux Install Guide" and the "Beginners Guide".
4. Used km to change to UK keyboard layout and then began the installer script (/arch/setup). I was installing from the core CD so I skipped the network steps.
5. HDD preparation.
This was fairly straightforward with two cautions:
(a) Make very sure that the external HDD (sdb) is selected for the operations.
(b) Remember to set the Bootable Flag for the first (/) partition on the HDD.
I chose 20 GB for /, 2 GB for swap and the remainder for /home.
6. The package selection and installation was fairly straightforward.
7. Configuration of System
This was section was straightforward with one warning:
USB had to be added to the HOOKS in the /etc/mkinitcpio.conf file!
I found this to be essential for my external USB HDD to function as a bootable device. Otherwise I got the same sorts of errors relating to unrecognisable file system types that other people have reported in the forum.
The relevant line from the end of the edited /etc/mkinitcpio.conf file is below:
HOOKS="base udev autodetect pata scsi sata usb filesystems"
8. Installation of GRUB was the other point where caution and/or correction was necessary.
When it asked where GRUB should be installed, I had to select sdb (my external USB HDD) and not any of the particular partitions on sdb. If the root partition sdb1 was selected then the laptop won't boot from the external USB HDD.
The GRUB /boot/grub/menu.lst as written by the installation routine specifies hd(1,0) which doesn't work when you try to reboot from the external USB HDD. When you boot Arch from the external USB HDD, as far as Arch is concerned - at that point in time - the external USB HDD is the first drive in the system. To fix this:
(a) When the Arch boot menu comes up, press e to edit the grub entries.
(b) Change the first line to hd(0,0)
(c) To the end of the kernel line add rootdelay=8
(d) Press b to boot the system with these temporary corrections.
(e) Once your Arch system has booted, edit the /boot/grub/menu.lst to make the above changes permanent.
The relevant portion of my /boot/grub/menu.lst looks like the following:
# (0) Arch Linux
title Arch Linux
root (hd0,0)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/... ro rootdelay=8
initrd /boot/kernel26.img
# (1) Arch Linux
title Arch Linux Fallback
root (hd0,0)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/... ro rootdelay=8
initrd /boot/kernel26-fallback.img
9. The laptop happily and consistently boots Arch Linux from the external USB HDD when it's plugged in before startup/booting.
Running Arch from the external USB HDD seems as quick as running Debian from the internal HDD.
So if there is a performance penalty associated with using an external USB HDD, my wife and I haven't noticed.
In summary, the three essential points to address during installation to an external USB HDD are:
Remember to set the bootable flag for the first partition.
Add USB to the HOOKS for /etc/mkinitcpio.conf file.
Correct the /etc/grub/menu.lst file.
I hope this is helpful.
Ted

Hi Rookie,
As you say, it is worth remembering the rootfstype= option for the kernel line just in case someone still has problems with GRUB after making all the other changes.
I was working with the most recent Arch 2009.2 release.
I only got messages about unrecognisable file system type when I tried booting with the "stock" or "as-installed" GRUB (before I edited /boot/grub/menu.lst). After editing /boot/grub/menu.lst to identify the drive correctly and add rootdelay, GRUB was able to do the rest and everything worked OK without any error messages.
Best wishes,
Ted

HT4889 Migration Assistant to update my new Mountain Lion iMac from an external USB hard disk drive, it is constantly saying that it is "looking for other computers". It doesn't find the external drive. Why is it looking for other computers?

I'm trying to use Migration Assistant to update my new Mountain Lion iMac from an external USB hard disk drive. I told it to look for a drive, yet it is constantly saying that it is "looking for other computers". It doesn't find the external drive ... it just endlessly looks for other computers. Why is it looking for other computers at all, when I told it not to?

Wow, the wording in Migration Assistant is misleading. I've never used it before, so I thought I would try to copy my files from the external drive ... my old iMac died, but I managed to get everything I need off it, using the 'cp' command in single-user mode. So I guess I'll just have to manually copy the files from the external drive to the new machine. I was hoping that Migration Assistant might help somehow, but obviously not.
Thanks for the quick reply!

Have new12 mini have added 16Gb ram and 2 500Gb momentus xt's. Want to set them up as stipped 0. i have a 3rd 2Gb external usb 3.0 drive that i could use to mirror the striped 0. how do i install the os after i set up striped 0?

i am guessing that i clone the main drive off to an external drive setup the striped 0 then clone it back. Also, do you think it would slow things down to have the 3rd external drive mirror as a backup to the striped 0. I have a time machine that is backing up the mini so i may not even need the external usb 3/0 drive for backup just use the time machine. Don't know if it would be more efficient to do a backup from the attached backup drive as apposed to using the time machine. if i end up using the attached drive as backup i will probably remove the mini from being backed up by the time machine.

Ok i have it figured out. its simple and straight forward. clone (carbon copy cloner) the main drive to an external drive. Set the two drives as a stiped 0 raid. Then clone the external back. Let Time Machine do backups. Set back and let her fly.

Booting from an External USB 2.0 Drive

Can someone please point me to an explanation on how to set-up a bootable drive using an external USB 2.0 drive and a MacBook?
Thanks

Well, as long as you have the drive you just need the software.
There are a few different ones that will do it. I use SuperSuper, but there is also Carbon Copy Cloner, and LaCie's SilverKeeper both of which are free.
Once you have the software, it is just a matter of running the cloning tool and then testing the clone to verify that it does indeed boot your Mac.

External USB 3.0 HD not recognised on Kirabook

Just got my Kirabook, i7 touchscreen, everything is perfect but for 1 thing: my external hard drive - WD My Passport 500 GB USB 3.0 is not being recognised, no matter which USB port I am using. It is not showing in the device manager also or any other screens. Is it a problem with the power of USB ports?
Same disk is recognised perfectly on my old Sony Vaio Z...
Solved!
Go to Solution.

Just got my Kira and having a huge issue with this. USB 3.0 drives showing up in Device Manager but not mounting. Only 1 out of 3 types of USB 3.0 drives my office is using is mounting. Drives which don't work are:
Hitachi Touro Pro USB 3.0 500GB
LaCie Rugged USB 3.0 / Thunderbolt 1TB
Those drives works pefectly under Win 7 and Mac OS.
I am not sure if the Hitachi is compatible or not with Win 8 but the LaCie is said to be Win 8 compatible on LaCie's product page. Looks like a hardware compatibility, may be a BIOS update or mother board USB comptroller update will resolve.
Tech support is on it, hopefully, they'll find a solution quick. I can't use my Kira without support for those drives

Installing Solaris 10 11/06 from an external USB CD-ROM drive

Hello. I recently purchased a new SunFire V245 SPARC server and would like to re-install Solairs 10 on it. However, the internal DVD-ROM is on back order from the vendor and will not arrive for a few days. I have an exteranl USB CD-ROM drive and the server sees it and the media when I access it from the Java desktop. However, I cannot boot from this device or see it in OpenBoot using any of the probe command. I've searched several forums and have seen that Solaris 10 can be installed from an external USB device on the x86/x64 platform. But I cannot find any information or steps on how to implement this procedure on the SPARC platform. Is this functionality possible? Or do I have to update my OpenBoot version? Please advise if possible. Thanks.

Hello Alex,
no, you can't use USB devices on SPARC as boot device.
The OBP (even updated ones) contains only support for the USB keyboard, but none for USB mass storage (which requires a device driver). The integrated USB ports are for slow devices like keyboard and mouse.
Using an external SCSI DVD-ROM works. Another choice is an installation via network.

[SOLVED] external USB HDD fails to install arch w/boot device ERROR

I've been working on installing arch linux via an external USB harddrive (specifically seagate free agent go 320GB) for 1 week now, and everytime I failed - until TODAY! thankfully I found this post, where user Dieter@be references this link, which displays BUG ID#17231 at the top titled "Can't boot LiveCDs 2009.08 (/dev/archiso doesn't show up)". the bug report states ::
I can't boot the LiveCDs 2009.08, neither netinstall nor core.
When it tries to access /dev/archiso it shows these messages:
:: Waiting for boot device ...
Waiting 30 seconds for device /dev/archiso ...
ERROR: boot device didn't show up after 30 seconds ...
Falling back to interactive prompt
You can try to fix the problem manually, logout when you are finished
ramfs$
reading further thru this bug report, I found a very insightful post by Heiko Baums (cyberpatrol) where he says the following, and I quote ::
Problem found. The link /dev/archiso wasn't created.
After
ramfs$ cd /dev
ramfs$ ln -s sr0 archiso
ramfs$ exit
it continued booting correctly.
And sg was also loaded after this. ;-)
as you see, the bug report was for the CD version, not the USB version - yet, my issue with the USB bootdisk was the same, (no matter which boot disk I tried = netinstall, core, .img, .iso, etc) meaning I got the EXACT same error = "ERROR: boot device didn't show up after 30 seconds ..." ! well, I figured that I'd try one of the new fancy ISOs found @ http://build.archlinux.org/isos/ - specifically I use/used archlinux-2010.03.04-netinstall-x86_64.iso.
upon running Unetbootin from windows 7, and choose to install the ISO archlinux-2010.03.04-netinstall-x86_64.iso to my first partition on my USB harddrive (that first partition being FAT32, and had already been set as bootable previously), that completed successfully. I rebooted, and choose to boot from USB drive, the ISOlinux bootloader came up as normal, I choose DEFAULT and off it went.... sure enough, it errored out at the same place as listed in the bug report ::
:: Waiting for boot device ...
Waiting 30 seconds for device /dev/archiso ...
ERROR: boot device didn't show up after 30 seconds ...
Falling back to interactive prompt
You can try to fix the problem manually, logout when you are finished
ramfs$
this time though, I issued the following 2 commands ::
ln -s /dev/sdb1 /dev/archiso
exit
from there, EVERYTHING worked as it should!
to recap: the solution for me was create a symbolic link pointing /dev/archiso => to my partition which held the archlinux netinstall (which is where I told Unetbootin to install it to)! done and done. I felt this needed to be posted here, as I could not find this solution after MANY google searches, archlinux wiki searches, forum searches, etc. honestly, I think it would be prudent to have this tidbit of information added to the Install from USB stick archwiki page as a side note to those that may run into this issue.
this is not the FIRST time I have run into this problem with a USB install of archlinux, but this is the FIRST time I found a fix! thanks to all the great posts I reference here, without this information I dont think I would have been able to install archlinux on my new alienware m11x laptop.
-peace-
PS: no amount of rootdelay=XX nor pmedia=usb nor usbdelay=XX would work in my above attempts either.

FAT16 here. Parted Magic sees my USB drive as sdd. I tried your way and surprise, surprise, it didn't work.
ln -sf /dev/sdd /dev/archiso
mount -t vfat /dev/archiso /bootmnt
mount : Invalid argument
I thought maybe you meant mount -f vfat /dev/archiso /bootmnt instead. I tried it too, it resulted in a kernel panic.
What else can I try besides installing from a IDE/SATA CD drive ? Because this issue is NOT solved. At least not for me. Wonder if "archlinux-2010.04.05-netinstall-i686.iso" from the here will solve it (really hope so).

Using Final Cut with external USB 2.0 drive

I use Final Cut Studio on a 2-year old MacBook Pro. The MacBok Pro has Firewire 800 and but only USB 2.0. I've been using an external Firewire drive with it for storing my movies. Now it is full and I need to get another external drive. However the new drives I've seen tend to be only USB.
My question: Will it be a problem to use Final Cut using USB 2.0? (The new drives are USB 3.0, but the computer is only 2.0). Will I be able to edit movies that are on the extenal drive? Or will I need to store the "in-progress" movies on the computer, and then move them to the external drive when I'm done with them.
And when I ask "will I be able to" I mean doing it without seeing endless beachballs...
(Also, if the response is "get another FW drive," then any suggestions as to which one?)
Thanks!
Dan

Let me make sure I understand this: If I store completed movies on the USB drive, I should have no problem viewing them, as long as I have no other external USB devices connected to the MacBook.
You can use the USB drive for archiving projects but as said before you shouldn't edit with one. While the nominal maximum speed for USB 2 and FW400 is not that far apart the two protocols work differently. USB 2 achieves the max speed in "bursts" which is not what you want for video.

Is that correct? Will it work to edit movies on the FW-400 drive, or should they be on the computer itself?
While you can have the project file itself on your system drive, all the media files should be on external drives. This way your system drive gets to run the software and the external keeps the media and renders.

FW800 is definitely faster. See a comparison here: http://www.barefeats.com/hard70.html

Need help with installing my Pioneer external USB DVD/CD drive into G4

Recently I bought the Microsoft Office 2008 for Mac Home and Student Edition DVD-ROM on my Dad's birthday for his G4 (OX Tiger), only to be reminded that the G4 only has a CD/RW drive! So I surfed amazon.com and got a Pioneer External USB 2.0 DVD/CD writer for dad, since all the customer reviews said the writer works on both PCs and Macs. But when my dad plugged the DVD writer into his G4, the Mac is not recognizing the writer. Anybody has any idea what is going on? Is there anything my dad can do? Many thanks!

Allen,
It's unlikely that anyone would have exact information about this. I have a 1.33 12" taken apart but no 1.07. However looking at the exploded views the LVDS cable is:
"LVDS Cable
922-6368
922-6432 (SS)"
For both the 1.33 and the 1.07 14"ers
That's even tho' the LCD panels are different designations.
Email me for more info.

Can I install windows 7 to an external USB 3.0 drive via bootcamp?

with the new airport extremes supporting USB 3.0, can I install windows 7 to an external USB drive via bootcamp?
i'm not willing to sacrafice any of the limited space on the SSD, but i'm very willing to get a good performing USB 3 drive, and use it as necessary with windows.
if this wouldn't work via bootcamp, can it be done on a windows PC and plugged in subsequent to the install to work on the road?

Installing Windows on an external drive is not supported.

MSI UBO-30 External Slim Bluray Drive not recognized under Windows 8.1

Hi, does anyone here have MSI UBO-30? It is an external bluray drive from MSI. For some reason the drive is not recognized under windows 8.1 64 bit (it just says USB device not recognized). But works fine if plugged into Windows 7 machine. Anyone encounter the same issue?

Try upgrading your usb 3.0 drivers on your system. That worked with My GS70 Stealth Pro...
