Some more details are required: -Are you using hardware or software RAID? -What is the process you are using to try to repair the bad drive? -What is your error message, if any? Once you post some details we?ll start trying to help you figure this out.

Raid configuration

That's probably because RAID 5 only tolerates 1 HD failure, (unless you have hot spares, in which case you can have many failures -provided only one fails at the same time...).

RAID 5 arrays can tolerate no more than one member drive failure.

You can recover RAID data from hard drive with RAID recovery software easily.
Tenorshare Data Recovery Enterprise is a comprehensive data recovery software that supports RAID recovery for RAID 0 and RAID 5. Lost data in RAID 0 and RAID 5 can be deeply scanned and restored immediately. Meanwhile, files and folders in RAID 0 and RAID 5 can be copied to other partitions directly.

I have a usr8700 NAS running raid 5. I had a drive fail and now I cannot access any of the data. I am researching the options of recovering the data. I found a few products and service options but don't...

Hello, I don't know your particular NAS, but a raid 5 is able to survive a single drive failure and continue to supply data ok because it recreates it from the remaining drives plus the parity drive. But, if you then get a subsequent drive failing before you've replaced the original failed drive, (and restored the data to it, which is/should be automatic) then it's really bad news. So, if you definitely have only had a single failed drive then you should just get an alert to warn you to take remedial action- ie, replace the drive. If the NAS has stopped supplying data then you may have got a multiple-drive failure situation. Just a general note of caution when working on a raid array: Some raid systems are clever and you can switch your drives around, some aren't and you can 'break' these raid sets just by swapping the positions of 2 drives, which is too easy to do if they're not labelled and you're trying to faultfind unless you're absolutely certain, just label your drives (and take a photo) before starting to swap drives about. Anyway,good luck with your troubleshooting.

Hi. We have a ML110 server with RAID 5 (4x250gb HD SATA) in a Adaptec 2610SA. The RAID has 2 Arrays (#00 Operating System and #01 Data). We have tried to replace a failed HD and since then the Windows...

Did you make sure that your hard drive has been made into a "dynamic volume" instead to the usual "simple volume"? It has to be "dynamic" before your can put it into a RAID configuration. You will have to use your RAID Controller to create a dynamic volume or to make the hard drive part of a dynamic volume.

1 logical harddisk degraded, RAID Poweredge

Revert back to original configuration of hdd in your RAID setup. Boot to SCIS BIOS and double check functionality of hard drives. The error is probably telling you that Disk1 is degraded because disk 0 is failing and you removed the wrong hard drive.

RAID 0 Array disappeared after reboot

I would try the hard drive on another sata controller/port to verify that the bad drive is in fact bad. If it is really bad, then no there is nothing you can do but replace the drive and recreate the array (losing all data!).

You can not 'recover' a failed RAID-0 array because there is no parity or mirror data on an extra disk like there is with the other RAID modes. This is why people recommend against using RAID-0 for important data (unless you take frequent backups): RAID-0 actually increases your likelihood of losing your data. Statistically speaking, you are multiply the failure rates of each individual drive together.
