Re: A hard lesson...
Happened to me with a home built PC with mirrored HDDs. For me it was the motherboard that joined the choir eternal.
No problem? Hah!
The company no longer made that motherboard and, indeed, no longer made any SCSI motherboards. Plus the disks weren't translatable by a new MB, probably due to an odd file system the original MB used (which is, admittedly, a software issue).
Hardware breaks and hardware problems cascade.
