i have a RAID 1 configured on a HP windows 2003 server. there is an HP application that manages the RAID. this manager shows a failing drive, i used the blinking light test to identify the drive. there is a picture of it.

can you help identify the drive and let me know where i can purchase one from?

Thanks.

where are you located?
are you sure it is raid 1?  it appears you have 3 drives.  0,1,2
are you sure its not raid 5?

your disk is seagate cheeta scsi drive ST3146807LC

you can buy the same disk from amazon
http://www.amazon.com/Seagate-ST3146807LC-146GB-SCSI-Electronics/dp/B003493T0W
or ebay
http://www.ebay.com.au/ctg/Seagate-Cheetah-10K-6-146-8-GB-Internal-10000-RPM-3-5-ST3146807LC-Hard-Drive-/69752735

raid 1 or 5, if the drives are hot swappable you can remove the failing disk and install the replacement drive.  the raid will rebuild itself.  the management software will show the disk rebuilding

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

i'm from Aus so a little hard to point you in the direction of the local computer shop.  Amazon or Ebay should be fine.

If you drill down through the management software it should tell you what the raid setup is.

it will say it there somewhere.

as there are 3 drives and 2 partitions (O/S + DATA) it appears to be raid 5.

actually the logical drives shows data - 139GB (maybe this is raid1)
OS - 139GB (this is possibly standalone disk, no raid) - dangerous

look through the properties and the drop downs, it should confirm the raid setup.

You appear to have three physical drives, and two logical drives, as only one of the logical drives is showing as degraded it's possible that you have one physical disk as you OS (C:) drive and a RAID-1 setup of the other two physical disks for your data.

You haven't told us what HP server you have so are the disk hot swappable? If so as you have already identified which physical disk has the problem, you should just be able to remove that drive and replace it with another one.

BUT make sure you do a full backup of your system ASAP, and if it takes time to acquire a replacement disk do another full backup BEFORE attempting the RAID rebuild.
