my lacie 250gb firewire HD stopped mounting on the desktop of my ibook ppc G4. Disk utility recognizes the drive, but the verification/repair process is interrupted with the following message:
Verifying volume “LACIE”
** Phase 1 - Read FAT
** Phase 2 - Check Cluster Chains
** Phase 3 - Checking Directories
Unable to read directory (Input/output error) Error: The underlying task reported failure on exit
1 non HFS volume checked Volume needs repair
I have as well updated the firmware to the latest with the lacie software, that recognized the unmounted external hd aswell.
Any idea on how to get this disk to mount without reformatting and loosing the precious data of this disk?
Don't know about the MAC part, but an I/O error implies that the either the source file cannot be read or the destination drive will not write. This is usually an indicator of a bad HDD. To check, I would attempt to connect the external drive to another computer. If it still gives the same indication, contact the drive manufacturer about data recovery recommendations

Disconnect the external firewire drive. Start the Disk Utility app in the Utilities folder inside your applications folder. With the Disk Utility window open, connect the external drive and power it on. It should appear in the left column. If not, your drive has probably failed and may have to be replaced.
If the drive appears, select it, click First Aid, then Repair Disk. Wait for this testing and repair to complete. Any problems should be resolved. If the display indicates irreparable disk problems, you may be able to use the Erase function to reformat the disk - but you will lose all the data on it. If repair seems to work, select the drive in the left column and click Mount in the toolbar. From the desktop, open the drive and see if data appears to be accessible. If so, close Disk Utility, restart your Mac and see if the external drive seems to work (repairs can cause some loss of data, but generally you won't be aware of the loss).
If you don't do so now, you should set up a backup of anything you don't want to lose (and we recognize you might be using the external drive for Time Machine). Disks crash and die. You should have a good backup when they do. Time Machine is your friend. Use it.
Is your MacBook as fast as the Lacie Rugged Hard Disk is?
Because solid state drive wasn't available on MacBook Pro at the initial time when it launched. Hard drives on all current Apple laptops are equipped with Sudden Motion Sensor technology. In fact, the Apple laptops that came with Sudden Motion Sensor are: All Intel-based Apple portables such as the MacBook, MacBook Pro, MacBook Air, PowerBook G4 computers starting with PowerBook G4 (12-inch 1.5GHz), PowerBook G4 (15-inch 1.67/1.5GHz), PowerBook G4 (17-inch 1.67GHz), and iBook G4 computers starting with iBook G4 (Mid 2005) have Sudden Motion Sensor technology. You MacBook may not have come with that technology that could be the reason you are unable to connect it.
Try using another USB cable or try connecting the HD into another computer. If same problem occurred, then the problem is isolated with the HD.
We can only save the HD by reformatting it once it showed up in the Disk Utility or on the desktop. Unfortunately, there's nothing that we could do if the HD is not mounting on the screen of the MacBook and not showing in the Disk Utility.
The only hope that we could think of is once the HD is detected by another computer. Meaning that we could still reformat the HD.
But if not, then you need to get a new one. Good luck!
I suggest an application called "Disk Warrior" it has always maintained high ratings among us Mac enthusiasts it has a hardware test function built into it and seems to be a little better at verify and repair functions than Disk Utilities which you can try also if you haven't yet. You may also consider trying a different firewire cable if you have one handy. Other than that a reformat should have put the disk back into an original state however the disk could have been damaged by not un-mounting it in rare mac cases. If you have the time you can also reformat the disk again although I would try the first two options first.
Some PC's cannot deliver enough power to the USB devices to function properly through the USB port.
Does your Lacie hard disk have a power input connector if so conect a power adapter to it before you put it into your USB port.
Another alternative, get a powered USB hub connect it into your computer then connect the Lacie hard drive to the powered USB hub.
Lacie D2 drives in my experience are infamous
for not having the most durable bridge boards. The bridge board is a
chip that has a chipset on it which take the SATA or PATA connection
and send it to the USB and or Firewire ports on the enclosure. If the
drive is powered up, you should get a blue light on the front. When
connected to either mac or pc
( porsches are MS_DOS formatted out the box ), if it does not mount or
does not appear in DISK UTILTY, then it is a high probability that the
enclosure/bridge board has failed and the drive ( if not making
grinding, buzzing, clicking or beeping sounds) will have to be
extracted and placed into a more stable enclosure.
This model appears to have a high failure rate in consumer reviews, so it may have physical damage on the disk. Only a re-format of the drive will isolate bad sectors that won't hold data.
Try re-mounting your drive after a fresh re-boot of your computer.
If the drive came with the manufacture's software to allow it to communicate with your computer, then try removing this software from your system and re-installing it again. This will repair a corrupt driver or I/O program.
Try using the drive with a new or different firewire cable. Other users have reported this drive working again after replacing the cable.
If you use Mac OS 10.2, you might not be able to initialize or partition the hard drive. This may require you to partition and format the drive on a different computer.
From your brief description, it sounds as though you may need to re-format the drive before it will work again.
