Mirrored RAID crashed, CAN'T retrieve data, SERVER '03 SBS, Business hangs on the line!!!
Posted on 2004-10-13
Running: Dell Prescision 620 Dual PIII Xeon 900Mhz, 1GB RAM. 3 SCSI Ultra 160 Drives. 2 of them were for data storage and file server (WD 9.1GB Ultra 160).
Most recent thing done before problem:
1) Tape Drive attached to the server (HP SureStore DLT15/30 External)
2) Some of the last couple of Windows Updates installed (all up until 10/12/04)
I have Raid 1 (mirroring) set up on the 2 storage drives. they are identical hard drives. Something happened.
Drives and drivers work perfectly fine. SCSI card BIOS picks up perfectly and so does device manager. Windows is not reporting any hardware problems and is stating that "devices are working properly".
When i open the Disk management MMC console it shows that both drives are unknown and unreadable. And also will not let me format. I know the data is still on the drive, I tried different software and utilities to get the data off nothing works. The Tape drive is SCSI and it works fine, so i know it cant be the contrller.
Unfortunatly the tape drive wasnt available for a couple of weeks, the last backup was created on the 30th, and thats 2 weeks of data lost!!
