Hello all,

I'm trying to figure out if this is a hard drive problem, a RAID controller problem, or otherwise.

First of all:
Dell Dimension 8400
Windows XP SP2
1GB RAM
Pentium 4 3.2 GHz Dual processor

Hard Drives:
- 160GB SATA Seagate - Contains OS and software files - NOT in RAID configuration, by itself
- x2 300GB SATA Maxtor Hard disks - RAID 0 Configuration, for storing large video files and other client files

Problem:
The other night, my completely operational RAID configuration started giving me some "write-failing" (or something along those lines) problems, then the drive suddenly became unreadable. After much rebooting, checking things, running diagnostics, I managed to get the files off without a problem. Then eventually, same thing - no access. My poorly-descriptive RAID controller told me "Error Occured (0)" on one of the RAID drives.

So I completely cleared the hard drives, reformatted them, removed them from the RAID config, and redid everything all over again. Sometimes it worked, sometimes it wouldn't. Sometime windows would boot, sometimes the windows startup screen would simply freeze and I'd have to disconnect/reconnect or deactivate/reactivate hard drives to get Windows to fully start up.

It is frustrating me to no end because there is NO CONSISTENCY to any of the actions.

Then I tried formatting them individually... worked fine in Windows. But I want them in a RAID config. As soon as I do that, Windows (or any other bootable formatting software) just gives me errors or freezes up.

I've done a plethora of other "scientific experiments" on this junk heap to try to get it to work, but I'll save you all the repetitive details - it simply didn't work.


So, my question is: Does anybody think this is a hard drive problem - the one drive is bad? Or could this be a RAID controller problem?

I want to know before I go blow money on a new hard drive. I just don't get it - nothing seems to be making sense here... and I have some pretty good knowledge on computer hardware, just not RAID configs.

I sincerely appreciate any help or suggestions. Thank you very much!

I just went to check on it... and after these four days of yelling and screaming at it... it magically shows a 600GB RAID NTFS storage space. That was done using a "quick format" with Seagate's Disk Wizard... which opens using a DOS boot.

So, as of right now, it seems to be working. But I fear as soon as I start putting files on the drive, it will give me errors once again. So, if you don't mind, I could still use some thoughts on this matter. Thanks!

I get the same problems... locks up tight. I power it off, then reseat the SATA cables and it works fine. On mine, it seems to be the cables, even the new ones I put in.

Thanks for the info... right now... in February, the same re-format is still working, so I guess that's all it was!

Hello,
I have the same 8400 and I betcha one of those drives is flakey. Either run the Dell diagnostics (if you still have that partition) or download AIDA32 here: AIDA32 download and review - system information tool from SnapFiles and query the hard drives for a SMART data readout. For example, here's what a good drive should look like and take notice that the program evaluates each line so you don't have to be an expert to understand it:

One final comment: I originally had a RAID 0 configuration and changed it to a single drive because RAID 0 is not that much faster than a single drive (at least on a Dimension 8400 at SATA 150 speed) and the configuration is more prone to failures because the OS is split across 2 drives. Yes, there are probably some instances where RAID 0 is noticeably faster but I haven't found them yet.
