Hi please explain more information about your problem. before any further assistance try to check it on other computers and see if its working or not if yes then take a full backup quickly, if not then: try replace the USB/SATA/PATA cable and check if it is working or not. if yes then take a full backup quickly, if not then: 1-this is an external drive: 1-1: it use as a normal external HDD for backing up data/movie/music/pics/etc.: option number 1:try to fix its partition clusters/sectors with some software like easeus partition recovery or ... option number 2:try to format it and then recover its data via recovery applications like easeus or "get data ntfs back" or... note: in all scenarios you may lost some files or content 1-2 it is used for speed up your computer or has the MBR or EFI boot partition and has an OS installed on it: try to fix its partition clusters/sectors with some softwares like easeus partition recovery or ... note: in all scenarios you may lost some files or content 2-this is an internal drive: 1-change the SATA/PATA cable 2-check its sectors or clusters via software (windows check disk or windows defragment option) for bad sectors or cluster issues 3-try to fix its partition clusters/sectors with some software like easeus partition recovery or ... if none of my solution works or software found some bad sectors that could not resolve it then or even you couldn't format the drive then: maybe it has a hardware fault and there is not much you can do about it by yourself and you should go for warranty service or replacement or asking some expert companies for recovering your data via some special hardware that it may cost you too much. best regards

How old is the drive and has your set-up always behaved exactly the same way or what's different now, please? Does this happen only with Word files or what? Is that LaCie's own Disk Utilities, or what Mac OS are you using which pluralizes that?

you can try a new lead or power supply. If it is internal just buy another monitor as not a DIY repair

try using "USB SHOW" install the software.
Note. Must be original software.

I'd suggest to try the device on a different PC. If the issue persists the problem is obviously with the drive itself.
