apple id number 11 Level 1 (20 points)

I have an external Lacie Harddrive (1TB) that responds slowly. I also have other external HDS (2) and they are no problem; there is no lag between command and function. The HD in question really lags with the spinning icon wheel almost all the time; even when I simply click on a file icon.


I have about 250 GB left on the drive;


Does it need reformatting? Is it going out?


Any help would be appreciated; and the best answer will win over $1,000,000 dollars; a free 4-wheeler and 1 year supply of sticky glue. (not)

    How old's the drive?


    There's basically three likely causes:


    1. faulty cable - test with another cable from one of the other drives

    2. faulty interface bus in the drives case - swap the drive into another enclosure and test

    3. physical wear on the drive platters - time to buy a new disk.


    Regardless, any data on this disk should be backed up immediately.

    thanks, but its realtively NEW....


    and I have started to copy its contents onto another drive; THANKS!

    So that possibly (but not definitevly) rules out 3. What about 1 and 2.?


    Have you tried either of these tests yet?

    I've tried test #1


    but I dont think I can accomplish #2, tech wise.


    I do appreciated your help. I plan to copy everything onto another drive and try and reformat it to see if that helps.

    while I still can.


    I did run disk utility and first aid, but it came up OK.

    I'm not sure if yours is the same model, but there's a world of painful stories from people having similar problems with Lacie drives in this thread.




    There are also a variety of solutions offered, some worked for some and not for others. Might give you some ideas for how to more forward (p.s., if its a double drive RAID unit it doesn't look like you can swap the enclosure anyway, so forget my no.2).

    I reformatted the first one and so far so good. After 1 week of copying files to another disk. I hope it holds out.


    All of a sudden..... egads.... Another one just went out. I have 3 Lacie 1TB drives.


    This last one will not even come on. Any suggestions? I have (had) tons of family videos on it. But I know I had at least 300 GB left on it.
