My computer is not recongnizing my Lacie F.A. Porsche 250GB Hard Drive.I have tried to connect it to several computers.It also was making a wierd sound but it has stopped now.I can be emailed at [email protected] thank you for your support

hi.
maybe problem is caused by your Power supply.
so i recommend you to do these:
1- remove the main hard drive and only connect "250GB lacie porsche hard drive".
and see is it recognized or not.
2- go to the bios (with pressing "delete key" at start of turning on) and navigate to power center.
then enable power saving mode.

It has most probably just reached its "end of life". Several years for a hard drive reading and writing is a good track record.
You can probably take the casing apart and replace the hard drive. Just make sure that this is an USB 2.0 interface before spending the money.

Try connecting the Lacie to another computer, if it doesn't work then the hard disk may need to be formatted using Disk Manager. I suggest you format as a primary partition in FAT32.
If it doesn't work then it is possible that the hard drive in the Lacie has failed.
To test the hard drive, remove it and connect it to an USB hard drive adapter and connect it to a working computer's USB port. If it deosn't detect it as an external drive and you connot open folders and files then it is faulty.
You can install a new hard drive in the Lacie and then format in FAT32
There are companies that can recover data from faulty hard drives BUT it will cost you an arm and a leg for their services.

Sounds like the hard drive in the Lacie has fauled.

conect your harddisk to computer whch has windows xp.
Then go to start emnu then type in run 'cmd"

then you can see command propmt.
Then go to your external drive letter like f:
then type 'chkdsk /r"
then pres "y'
then it fix error on hardisk.
Aslo you can format it .
Just take backup of data which you need then right clik on drive licon and format it.then it works fine.

I think the migration assistant (in the utilities file in your application folder) can transfer files direct via USB.

Does your drive make any unusual sounds like any of these: http://datacent.com/hard_drive_sounds.php ?
If yes then you got a problem - it's something mechanical with the heads.
If it sounds normal or doesn't spin up at all - try to connect it to another computer and if still no go - remove the internal drive from enclosure and connect directly to PC via SATA port.

Another imporant thing - does it make any new sounds similar to any from this page: http://datacent.com/hard_drive_sounds.php ?
