Of course changing the BIOS setting to RAID will NOT wipe your disk. I have gone back and forth several times.
If you were to go the full hog and use the BIOS setup screen to establish RAID partitions on the disks, then yes, your disk will be affected. But we are not suggesting you do that.
Simply switching the BIOS setting to RAID modifies how the BIOS presents the drives to the kernel, fixes the problem, and leaves the drive contents unaffected. Along the way, it seems to go a little faster too.
Changing the SATA mode in the BIOS from IDE to RAID solved the upgrade problem for me too. The major problem was ubuntu would not start unless I edited the grub menu and put the parameter acpi=off after the parameter splash. Turning off the advanced configuration and power interface then created shutdown problems with error messages. Thanks for posting the BIOS change. It solved the start-up problem and the shutdown problem. Now, the upgrade from ubuntu 7.10 to ubuntu 10.4 was completely sucessful. I'm impressed with my Dell 530 and Hardy Heron.

I have tried both RAID and IDE/all_generic_ide and know that both work well but I'd like to understand which is the better of the two.
I've read that Dell pre-configures the machines as IDE because Vista isn't compatible with RAID. But I'm not dual-booting and have no intention of ever installing Windows on my computer. Does that mean RAID is the better choice for me?
Is RAID faster than IDE? More reliable? What is the difference?
Setting the BIOS to RAID mode seems to make drive access a little faster subjectively, but it's not much. I haven't measured the difference. I may be imagining it. It ought to be faster, since it isn't pretending that a SATA drive is an IDE drive any more.
It isn't more reliable, since the drives themselves are still being used as single drives, not as an array of drives (RAID=Redundant Array of Inexpensive Drives).
The difference is simply that the way the BIOS presents the drives to the kernel changes. It switches from an older way (IDE) to a newer way (natively SATA). Sort of. Something like that, any way
I Had updated the bios to the newest version on my Inspiron 530 (it was version 1.0.10 and now its 1.0.12 on my dell).
Ubuntu 8.04 is working fine, no aditional changes, just the default instalation!!!
Go to Dell suport site and input your dell' s service tag (a group of sevem characters on machine's back) and follow the instructions.
i have a dell 4700 with two sata identical maxtor hard drives, when the second hard drive is pluged in, the bios sees the first sata-0 as maxitor and the second sata-2 as unknowen, and some times sees it as maxitor, when i first put the two hard drives in everything was good and after i started filling up the second hard drive it started coming up with errors, 87 errors
maxitor is replacing the drive, but i have never been convinced it was the drive. might this be part of the problem your having ? i have no RAID setting in my bios.
