Ok, you only have one shot at getting anything back, and this is, IF the interface circuitry is faulty and the HDD is NOT. What you need to do to prove this is to remove the HDD from the housing. Then obtain a suitable USB adapter, then using the adapter connect the HDD to the PC, IF it is recoverable you should be able to "See" it in My Computer. If it does indeed show up, then simply use it as you would any normal HDD. If it does NOT show up. The most likely the HDD has died and there is damage to the Internal electronics or the main Board. IF it is suspected that the main board is the problem. IF you obtain an EXACT Make and Model, you can swap the main boards and get the drive going again to recover any data. Otherwise, you cannot do much else.

First test your CPU then tast all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
good luck

You need to format the drive so that it is compatible with your Mac OS. If you have any data on the drive it willl be erased when formatting.

Please rate my solution. Thanks!

Steps to make your drive Write Protected Or Remove write protected:
1. Open Registry Editor by typing regedit in Run dialog.
2. Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
3. Find a sub key inside it named “StorageDevicePolicies”. If it does not exist there then we need to make it. Right click on “Control” key -> New -> Key. Name it “StorageDevicePolicies” without quotes.
4. Now right click on this newly created key and then click New -> DWORD value and name it as “WriteProtect”.
5. Modify this key and give it a value 1.
6. Click OK, and remember to restart the PC.
Now no more data can be transferred to the drive but to start using the drive again just give the “WriteProtect” key a value of 0 instead of 1 and restart the PC.

If you or a friend have another computer, please try plugging the drive into another computer. If it shows and works correctly then there are 2 other things I would try. You may have done this already but try a different usb port. If you are using a front port, try using one of the rear ports. I find that the front ports are not as reliable as the rear since it adds another short portion of cable and an additional connection at the mainboard. You may have received an update that made the USB act differently. The second thing I would try is plugging in the drive and then before trying to access the drive, run a hard drive diagnostic like Western Digitals diagnostic for Windows or Maxblast. You may find that the drive has failed. Its also possible that the enclosure has failed. If all else fails, try taking the drive out of the enclosure and puting it directly into a computer. You may be able to transfer data to another drive if you can see the information on the drive you have removed from the failed enclosure. Hope this helps... Dale

Unless you use a specific software package to resize the existing partition (partition magic et al), the original partion and contents are effectivly erased... they can be recovered using disk recovery software in most cases though

If you still have the source files and both systems can see and write to their respective partition of the Ext HDD, then the easiest way to move forward is to just copy your files back onto the assigned partition.

I would seek out the latest drivers for the card in addition to checking to see the firewire card is properly installed. I would test the cable with another or ports. The D2 has a various array and combination of Firewire ports on each model. Also, try bringing the drive to another computer, to eliminate all other variables. Always of course, properly eject external hardrives and wait for confirmation whenever disconnecting it from the computer, and allow the drive to spin down before turning it off.

Just an idea. When you set pass words or any important information write all information in a note book and keep it in a drawer someplace where you will not lose it. When things change write the new ones down and cross out the old ones. I save a lot of head aches that way.

Pushing in the paperclip should unlock it, but if still jammed, may have to wreck drive by pulling off front of drive drawer thing. Maybe try putty knife to push cd down some of that's holding it from opening.

Replace perhaps, but repair is most difficult. The electronics are miniature and it takes special tools to do repairs.

Two ways this can go. If you are talking about the entire hard drive pulling it out and plugging the whole drive into another pc. Then you're fine If you are talking about disassembling the hard drive and moving the disks inside. This is not something you can do. This is what you will need. 1) a certified clean room surgical grade 2) tape 3) A matching drive/ hd board down to revision number 4) presision screw tools. 5) patience. Or you will need to contact a professional data recover company.
