Posted April 29 Hello guys, after one of the two hard drives failed we tired to boot the PC of the other drive but without any luck. Trying to fix the bootloader with an USB drive or a Win 7 CD didnt help and even Clonezilla didn't do any good. We need the installed programms to work so setting up a new Win 7 machine wont do us any good. Loading drivers while in the install screen of windows didnt help either, cause the PC just says that those drivers arent fit for the PC (they are extracted from the PC's HDD) and so Windows cant recognise the filesystem and therefore not fix anything. Has anyone an idea of what to do? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted April 29 Do you have backups to restore? How was this raid setup? What raid card? How important is this? If this is a critical system get a data recovery company involved here. Did you make images of these drives before touching things? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted April 29 sure you took out the broken disk?. raid 1 is mirroring, so you should have a replica on the other disk, did you try swapping the two sas or sata ports? it might need that to get the bootloader correctly. If raid1 was initialized from windows after installation, it could be your bootloader was on the first disk, and mirroring are only from the windows partition on the second disk. So always set up RAID in bios or controller card initialization before windows loading. Link to comment Share on other sites More sharing options...

Posted April 29 Author We have Backups for the drives As far as I can tell (setup was way before my time at the company) it was the internal RAID Controller for an HP Z400. One of the drives is working but the other one isnt. It was setup before installig Windows and after like 4-5 Hours of troubleshooting i get into the windows repairtool, but it cant restore anything cause i doesnt understand the data strukture of the drive Link to comment Share on other sites More sharing options...

Posted April 29 Have ya tried switching the storage settings in the BIOS between RAID/AHCI/SATA/IDE mode? Win7 has particularly odd reactions to different modes of on-board controllers. Also boot into a partitioning tool like MiniTool PartitionWizard and see what the disks' configurations are. If it's on software-RAID, you're screwed. But if it is the sort-of "hardware" RAID using the onboard Intel chipset, it's usually easy enough to reconfigure the remaining disk to boot solo.

Posted April 29 to rebuild it's usually just replacing broken disk with a working disk and it should rebuild itself. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
