Raid Drive causing freeze at dell splash scre

Dell / XPS 600
January 30, 2010 at 15:59:16
Specs: XP
i've unplugged my two RAID 0 drives from my XP machine... accidentally (i was unaware i had a raid 0 direct from dell)... upon plugging them back in only one seems visible, it's too much of a coincidence that the drive failed when i unplugged it but i guess anything is possible

what's happening is if i plug drive a (half the Raid 0) in i go past the dell splash screen, into setup and i can see the drive.

if i turn off the machine, switch drives (same power and sata data cables) and turn the machine back on, it hangs at the Dell splash screen, the progress bar goes to 100 and it freezes, fan is running fine.
i restarted and pushed f2 right away and the top right changes to "entering setup" but it still freezes when the progress bar reaches full... freezes even with the text "entering setup" at the top.
so it seems only the one drive is causing this freeze, i'm hoping it can be fixed because while i do have backups there's a few days work on there i could really use.

any ideas?

thank you

mg

With Raid0 your data is shared across the two physical disks so unless both disks are connected and fully working, and the raid controller is properly configured then there is no way the operating system can boot.

Were you having problems before you "accidentally" disconnected the drives?

Ill tell you why it was accidentally (your quotes seem like you're questioning it) i have never seen a RAID 0, for years i thought i had one 320 gig drive, i was looking to add an internal backup and saw a dusty 160, assuming it was not in use unplugged it and replaced it with the 1TB i bought, then all hell broke loose.

Why does one Raid drive go past the DELL splash screen, allowing to go to f2 to see it, but the other freezes at the DELL splash screen?

there were no problems before i disconnected them.

Update... the Questionable RAID drive that was stopping the machine at the DELL splash screen, shows up under XP (i installed a fresh OS on the new 1TB drive) but says "the file system is corrupted and unreadable" i assume this is because it is half a RAID setup and not because the drive is dead? is this assumption correct?

SO it seems both drives are ok, one stalls at DELL screen and one does not, but both show up in my computer with a diff fresh install drive.

how do i realign the two RAID drives to get back to where i was i guess is my problem.

Did you damage the sata cables?

No i've moved the three cables around and the ports... all work fine with the other two drives (1tb with fresh windows install and the other RAID drive that hasn't been causing problems)

is it possible to take two RAID 0 drives and install them in a totally new machine? i'm asking to understand RAID, is it just a matter of setting them up properly in a new machine using RAID util or are they in some way tied to the setup they have been using? sorry i know i sound kinda stupid... i've just never dealt with RAID before

Sorry for my question about the Accidentality of your situation. An accidental disconnection of a drive in my opinion would occur if for example, you tripped while working on the system and yanked the cables while falling. What happened to you was the consequence of an uninformed, possibly misguided , but deliberate action on your part. Not an accident.

My suggestion is to remove the new 1tb drive.
Put the two original 160s back in and cabled exactly as they were originally. Then boot up into bios to see what RAID setup options there are in bios. The drives and operating system were configured for that hardware environment and in answer to your earlier question, No, I don't believe you could connect them in a different computer and recover the data, Unless it was an identical Dell model with the same Raid controller. If you cannot get it working again the entire system content is hosed.

I agree with Richard. Although I'm no fan of RAID arrays, you'd be better off connecting the two 160GB HDD's exactly the way they were & using the 1TB HDD for backups & storage.

It's impossible to run 1/2 a RAID 0 array. The data is striped (split) across both drives. For example, say you have a 100K file...50K might go to HDD1 & the other 50K to HDD2. But if you were to try to read just 50K from either drive, it would be impossible. You'd need both halves to make a complete & readable file.

BTW, windows sees the array as a single 320GB HDD, not two 160's...but you already know that. lol
