Hello, I've got some problem trying to install 64Studio 1.0 AMD64 and 1.4.0 AMD64 on my new config. Here is my config - Core 2 Duo - WD Raptor 74Go => RAID 0 - ASUS P5W DH - DDR2 2Go I tried several istallation of 64Studio but unfortunatly, it failed at different level of installation. I built a RAID 0 with my 2 raptor: I manually made the part on my HDs: 1st HD: 1Go => /boot 6Go => SWAP 63.7Go => 64Studio 2nd HD: 63.7Go => 64Studio Then I created the RAID 0 with the 2 volumes etx 3 / After accepting the modifications, I got systematic freeze with 64Studio v1.4.0 after the formating operation. ??! Tried then with v1.0, I passed the format operation but it failed during the installation of the "base package" (=> warning message from bootstrap saying that some package are corrupted) and another time during the installation of the system's packages. I checked the integrity of my downloads => everything is ok. I tried to burn my CD/DVD at very low speed => Nothing changed I tried to install some other linux (UbuntuStudio, Ubuntu x64) distribs => I got the same problem! I tried installing windob => Ok. I'm not an expert with linux, so if you guys could give me some ideas? Is my raid 0 configuration ok?? FYI => I disabled the RAID in my BIOS, that's what I did on my server with ubuntu and everything was ok... Thanks for your help.

Tried it long ago

My attempt (2years ago) was not successful, and ever since I have split up my two drives. The first drive has the system stuff: 10Go for /, swap, 8Go for /var, and rest = /home Second drive: /audio This way I separate the audio drive physically from the rest, making it less prone to hardware xruns So, If you cannot get your raid going you could opt for something like this. Everything is working so well, I see no point in changing it now. Besides, If one of your HDs conck now you will have lost EVERYTHING. I keep backups of important files on both drives - you never know. Of course it is all a matter of choice. I would suggest having a separate partition for / and /home though. It makes re installations or upgrades to new versions real nice in that it seems that nothing has changed on your system (given you keep your home partition intact and use the same user and password)

Beware of fake RAID chipsets!

Whenever there are problems with RAID on Linux, it's usually because the motherboard in question does not have a true RAID interface. These so-called 'fakeraid' chipsets depend on a Windows or proprietary Linux driver for their RAID functionality. This leaves you with a few options... 1. Switch off the 'fakeraid' in the BIOS and use the discs separately, as Quentin suggests. 2. Switch off the 'fakeraid' in the BIOS and set up the two drives as a Linux software RAID (md driver). 3. Switch off the 'fakeraid' in the BIOS and buy a genuine hardware RAID controller card with Linux support (e.g. a 3ware RAID card). Do you get the impression we don't like fakeraid? :-) See: http://linuxmafia.com/faq/Hardware/sata.html#fakeraid for more details.

RAId pb

Thanks a lot guys for your replies! i appreciate your support. Concerning the RAID, You are right about the fakeraid, anyhow I always disable the fakeraid in the BIOS when installing linux and it worked. I finally found out that one of my 1Go memory did'nt work properly and generated errors when loading the system installation. I finally removed it and it worked fine. i think I will convert to a single drive instead of RAID, don't wanna spend more time with installation pb. Thanks again for your support. Stef
