Unhappy External Hard Drives for Linux


Hello all,

I have a Redhat 8.0 Server on my machine and would like to have an 300GB external Hard Drive installed on this machine for my extra storage.
Every dealer of External Hard Drive I see does not have Linux in their Support. Is there any Company where i can get a 300GB external Hard Drive for Linux.

Thank you
Vikram Gollakota

are you trying to hook it up by firewire, usb2, or other? Just because they don't "support" linux doesn't mean it won't work. It just has to be mounted and formatted to work in linux. Most if not all external drives should work just fine in linux.

Hello Heath,

Thanks for the reply
Actually i am looking for a USB hook up method. So I can go ahead and buy any External Drive and try to hook it up. Do I need to do some special mounting to get it hooked up with Linux.

Thanks
Vikram

Many times no. Since you are using redhat I am not sure of the specifics. Using debian it is hotplug that makes usb/firewire devices show up. then just mount the dev under a folder and you are ready to go. You could always burn a knoppix cd and boot off that. Then you would know whether your hardware is working correctly or not.

I'm sorry to talk about my problem here but i was wondering if anyone knows how to make usb2.0 work under debian?

I have an external HDD and it's a usb2.0 drive (tested fine under windows), with debian, it's recognized (i added a part in the fstab file) and i'ts working fine but the transfer speed is less than 1Mb/s which is why i assume it's only working as a usb1 drive.

what kernel are you using? I believe the support is included in kernel 2.4.23 and above (including 2.6) If your kernel version is lower than that you may need to update the kernel to get the module support.

try booting with a knoppix >ver 3.4 cd. http://www.knoppix.net See what your transfer speed is on it. You can boot off of either the 2.4.x kernel or 2.6.x kernel from the same cd. Since knoppix is based on debian, this would tell you if the kernel version is what is slowing your drive down or if it is a driver issue with your particular card.

issue the command lspci and post what the usb controller line says. We may be able to figure out more about the problem with that info. also use dmesg to see if there are any other errors on hardware loading.

Hey,

Before you get happy with the USB 2.0 drive, is there a reason you want USB over Firewire? IIRC Firewire has a lot more throughput than USB, and might be better if you don't have a reason for needing USB. BTW, what kind of USB drive did you buy? I have to go out and buy one at some point too. My laptop doesn't have a firewire port

USB2 is faster than firewire and the linux driver is more stable.

usb 2.0 has the same theorical speed than firewire
I would have bought the firewire version but my bro comp doesn't have firewire, and usb 2.0 is more common than firewire
