If it helps the drive is a Seagate st3500830A

 

Have tried drive on other computer and it works
What could be issue with first computer

 

How is the drive powered?

 

standard (e.g. not USB)
Seems to be problem with computer itself as this just happened with another smaller Ext HDD

 

Looking more and more like a windows XP OS problem.
Any thoughts on how to repair???
l am feeling lonely .. heeellpppp

 

Does it have external power, or is it pwered through the USB port?

 

primary HDD: external power - not USB
FYI: have three external HDD: one works (external power) and 2 do not(one external power and one USB powered)

Could it be XP or maybe even USB issue,

 

If the drive you are having a problem with is a USB-powered one, that may be the problem. Machines vary a great deal in how much power they deliver to USB devices, and many do not deliver enough so they use a second USB connector to increase the power supply. You should use 2 connectors if you have them available since it sounds like your drive is not getting enough power.

 

No the main drive I am really having trouble with is the non-usb, HDD with external power

 

Move all the data you need to save from the drive. Then remove all the partitions, make new ones, and do a full format.

 

Do you really think it is a HDD format problem.Especially as this particular drive works fine on other computers

 

It could be. But I don't understand how these drives are set up. If the externAl is not usb and has external power, how is it connected to the computer?

 

sorry for confusion
HDD powered externally (e.g.not USB) but connected to computer by USB

 

OK.

Are the other machines that it works on also XP?

If it's not too much trouble, I'd still try removing those partitions, making new ones, and reformatting on the machine that it is having trouble with. It will be interesting to see if that process can complete without errors.

Does that XP machine have any other problems?
