Hi people, I decided to install RedHat on a spare disk I had. My system is a P4 2.4Ghz with an ITMAX2v2 motherboard (onboard HPT374 controller). I have a 4GB HDD on a normal IDE channel which has Windows XP on it (and WAS the boot drive), A DVD drive, DVD-R and Zip250 on the other standard IDE channels, then two 40GB HDD in RAID0 configuration on the HPT374 with an 80GB partition, then finally a single 10GB HDD on which I installed RedHat.

All seemed well untill I booted into XP, my 80GB RAID drive vanished! I took a look in disk manager and the drive is there, but it sees no partition on it. I assume what has happened is that RedHat has put the bootloader on the RAID set, and somehow corrupted or removed the partition information.

Does anyone have ideas on recovering this partition? I have about 50-60GB of media data I really need to get back, I know this is not strictly a linux problem but I know that you guys will have a much better chance of helping me out than any people in windows help sites

I hope someone can help,

Many Thanks,

Justin.

I don't think it's a problem with your RAID drive, though I've never used a RAID drive so I don't really know. However, after having read many threads about dual booting and problems, it seems to me that there is a problem with your grub file (grub.conf I presume--I use LILO so I'm not too sure--and I think RH uses grub by default). Anyway, it would seem as though it's not configured to recognize your XP partition.

Could you provide a bit more information no how your drives are set up? For instance:

/dev/hda = XP
/dev/hdb = CDROM
/dev/hdc = RedHat
/dev/hdd = DVDROM

I'm quite sure this isn't the right set up, but an example anyway. Check your grub.conf file to see if the WinXP drive is listed as one of the options to boot. It doesn't sound like it is. Since I have no idea what your hardware set up is like, I did a search for grub.conf here at LQ to see what I could come up with. I've never used grub, so looking at the grub.conf files don't really explain much to me, but maybe for you, some of these links will prove helpful. Keep me posted and I hope this helps.

Ok, here is the info I managed to get, not sure if it helps though!
