Seagate GoFlex Pro, USB 3 & Linux Mint 11

Okay – I’ve had my Seagate GoFlex Pro 500 GB external hard drive for some time now. It is USB 3 and I run Linux Mint 11. Like many others using Linux Mint (or Ubuntu) after some time, about an hour or so, the drive simply disappears. Unplugging and plugging it back in doesn’t work nor does plugging it into another USB 3 (or USB 2 either in my case – a Dell XPS 15 L501X) will allow the drive to be seen again. Apparently, the issue is with the Seagate firmware in the drive and the fact that there are different “wake up” mechanisms being used. And, Seagate apparently does not publish how wake up is being done. Here is apparently how to fix the problem:

sudo gedit /etc/default/grub

Modify (basically adding “pci=nomsi”)


to read

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

Then run

sudo update-grub

I found this at after much Googling.

[UPDATE] This does not seem to work.  I was uncompressing a very large file to the GoFlex and left the room.  When I came back an hour level the drive went “missing” and nothing could get it back except a reboot.  It seems that this does not happen under Windows 7….

About Mike Pelley

Let’s see… A little about me… I’ve been around information technology since 1983 with computers such as DEC Rainbows (weird machine – the standard DOS couldn’t format its own floppy disks – remember them? – and I had to format them on a friend’s IBM PC) to Radio Shack TRS-80 to Apple ][e and Apple //c in the beginning. I have programmed in 8-bit assembly language on 6502, FORTRAN and COBOL on IBM System/370 (and I still hate JCL), VAX BASIC and COBOL (and a weird and massive WordPerfect 4.0 macro) on DEC VMS (Alpha), C/C++ on Digital Unix (ALPHA), and C/C++, Perl (it may be powerful but I still hate it), PHP on Linux (Red Hat, Centos, Ubuntu, etc.). I have work with databases such as Digital RDB (later to become Oracle RDB), Oracle DBMS, Microsoft SQL Server, MySQL and PostgreSQL on VAX, Alpha, Sun and Intel. Check out my professional profile and connect with me on LinkedIn. See I still think that Digital created some of the best ideas in the world: VAX clustering, DSSI disks (forerunner to SCSI) and the Alpha processor (first commercial 64-bit processor – Red Hat screamed on an Alpha!). DEC just could not seem to be able to give air conditioners away to someone lost in the Sahara Desert! VMware is one of the best ways to get the most out of an x64 server. And I have tried Oracle VM, Virtual Box and Microsoft Virtual Server. Outside of that I am a huge military history buff starting in the early 20th century. I love Ford Mustangs (my ’87 Mustang GT was awesome) and if I had the money I would have a Porsche 928S4. If I had a lot of money I would have a Porsche 911 Turbo. I also play too much AmrA 3 Exile mod. Over 5,000+ hours... I have a wonderful son, Cameron. I have a long suffering (Do you really need all that computer junk?) wife, Paula. I live in Paradise, Newfoundland and Labrador.
