LaCie Hard Drive External Enclosure

Yeap - I have... in fact...

I should warn you... their controllers have issues when a handfull of blocks go bad on their drives. Bad sectors on a drive is nothing to worry about. (unless that number increases all the time)... When connected to a computer, the filesystem just mark them as bad and you are done. When used in a RAID (again, connected to a computer) it marks them bad on both drives (to avoid problems)..

When you use a USB/FireWire etc bridge... you have no block access to the drive and if a drive gets a bad block then your whole drive just basically reports the error (from the bridge to the machine).

So check your drives in your computer first... make sure it has no bad blocks... then you can use it on your enclosure. If the enclosure stops working (and LaCies are well known to do that) then it could very well be the block issue. Try the drives on your computer and you can use it for something else... (just not for RAID 0 on a enclosure any more).

and no... if the enclosure dies.. moving the drives to your computer will not help you recover the information... so always keep a backup 😀
