CurlyWhirly Posted April 6, 2007 Report Share Posted April 6, 2007 I have seen this screen before but never took much notice:Does anyone know what it means by 'Fault Tolerance' as I had no idea that hard drives had this feature!Also what does it mean by 'Overhead'?

andsome Posted April 7, 2007 Report Share Posted April 7, 2007 This screen is in Disk management. From here you can format that drive. I don't know what overhead means. You need this screen when you first plug in some USB external drives. They have to be formatted to suit your requirements, e.g. NTFS.

They have to be formatted to suit your requirements, e.g. NTFS.Yeah I've formatted a hard drive in the past but never took any notice of the 'Overhead' status.After googling I think that 'Fault Tolerance' is referring to a RAID (mirror) system and so I can assume that Overhead is something to do with RAID Quote Link to comment Share on other sites More sharing options...
cozofdeath Posted April 8, 2007 Report Share Posted April 8, 2007 This url explains it a little.http://www.microsoft.com/technet/prodtechn...e/10w2kada.mspxFault Tolerance - Whether the drive uses Windows 2000 fault tolerant features, such as mirroring or striping.Overhead - The total additional drive space required as a result of the fault tolerant feature used.

CurlyWhirly Posted April 8, 2007 Author Report Share Posted April 8, 2007 Thanks cozofdeathI see now what those 2 entries are referring to:Fault Tolerance - Whether the drive uses Windows 2000 fault tolerant features, such as mirroring or striping.Overhead - The total additional drive space required as a result of the fault tolerant feature used.I have tried out RAID 0 (stripe mode) and it caused me nothing but trouble so I went back to a 'normal' setup.

Scarecrow Man Posted April 9, 2007 Report Share Posted April 9, 2007 Fault Tolerence means RAID. RAID 5 is ideal if you have the disk cost. Quote Link to comment Share on other sites More sharing options...
CurlyWhirly Posted April 9, 2007 Author Report Share Posted April 9, 2007 Fault Tolerence means RAID.Yeah I meant that RAID 0 was giving me trouble as one of the hard drives would lose 'sync' with the other meaning that I had to rebuild the array again.As this took over an hour, I soon got fed up of it although it didn't happen every time I booted the computer thank goodness.This turned out to be a bug in the onboard RAID chip which I presume has now been patched?Even if it has, I won't bother with RAID again.I could of used mirror mode which would have been fault tolerant - never mind as I've since got rid of the other hard drive!RAID 5 is ideal if you have the disk cost.Isn't RAID 5 a little OTT for the average home user not to mention expensive?

Scarecrow Man Posted April 9, 2007 Report Share Posted April 9, 2007 RAID 5 is a little OTT, which is why I said if you have the disk cost (meaning you have enough disks), but it does provide the best performance as well as redundancy.
