I have an SCSI Adapter Adaptec Ultra 160 Model 29160, with 3 disks Seagate Cheetah ST39204LW, when i install Windows nt 4.0 and then try to establish a mirror, it's give to me an hardware error when executive services are starting, the code is "unknown hard error c0000221" I've change the SCSI Adapter and give me another similar error, my question is: "Is there any problem reported anywhere about this products with NT?". Thanks to all.

According to Knowledge Base article Q101096, this message means that some portion of the operating system has been corrupted.

"This error can appear in many different formats, ranging from a blue system error screen to a dialog box. The type of format depends on how much of the operating system was loaded when the corrupted file was detected.

If you receive this error message, the file listed along with the error is corrupted. You need to either obtain a new copy of the file or reinstallWindows NT or Windows 2000. If reinstallation fails to solve the problem, then a hardware or network problem may exist."

You might look at how you are trying to establish your mirror. Three disks is a bad number for a mirror, where you need pairs of identical partitions.

If your three disks are identical, I would recommend using a raid-5 group instead of mirroring. Your boot partition cannot be included in a raid-5. Partition each disk into a small boot partition and a large data partition. Using Disk Manager, set up raid-5 on the data partitions. You should be able to mirror the boot partition, but read and follow the instructions carefully. You will be left with one unused small partition on one disk.

Good luck.
