No problems forever; using partitioned external Firewire-connected HD for backup and for extra multi-media storage. Suddenly, nothing. No hint of the drive on the screen. Blue light/button solid. No apparent power problem. Firewire tests OK.

Re: LaCie BIG HD suddenly invisible to my Mac
from the description either th drive or the 1394 logic board has failed. Try having the technicians at you local PC shop swap the actual hard drive from the Lacie enclosure into a new enclosure and test it. If it works, buy the enclosure and you're back in business, if it oesn't and you need the data on the drive comment back with your Country, State & City and I'll refer you to a good Data recovery specialist in your region.

It sounds like your old laptop drive had 4 partitions on it.
If that is the case and you want it to be only one partition then you'll have to back up anything you want to keep in those partitions and reformat the drive as one partition.
You can reformat the drive using the Disk Management utility in Windows.
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.
Fat 32 is the only system that would work on all 3 os's direcly. You could use NTFS if you only write those big files on windows, you could read it on both linux and mac.
NTFS 250 (or ext2) HFS 120 If you need to use the last partition on of the operating systems the fat 32 would work here, but as you know the problem with that. Looking at the wikipedia page ext2 would also work.
initially, pls verify that it is indeed an external storage problem rather than a laptop USB issue by trying other USB devices and determine if they are recognized and working;
disassemble the enclosure of the Acomdata external hard drive and remove the actual hard drive;
you would need the use of a 2nd PC, a desktop that could accommodate the HD from the Acomdata (IDE or SATA);
install the HD from the Acomdata as a Secondary Master or Slave internally to the 2nd PC;
boot the 2nd PC and determine if the HD from the Acomdata will be recognized as a local drive;
chances are that the partition of the HD from the Acomdata was messed up. This would explain the blinking blue light;
download and install a file recovery program. An example is GetDataBack (unfortunately not a freewarebut DEMO is available) and do a recovery. It would take some time based on the size of the HD from the Acomdata;
temporarily save the recovered data in the 2nd PC. You can burn this likewise into a DVD backup should the 2nd PC be capable of that;
after recovery, re-partition and format the HD from the Acomdata while still attached to the 2nd PC;
should the re-partition and format be successful, you can transfer back the temporarily saved recovered files;
a nice, simple, fast and safe partitioning/formatting software is Partition Magic (unfortunately not a freewarebut FREE TRIAL is available).
should the re-partition and format be not successful, you can replace only the HD and/or claim warranty.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
This is a common problem with external storage.
Based on your post/description:
1. Your laptop does not recognize the external hard drive via its USB connection - try on a different computer - if it is still a no go, then it's not a PC problem;
2. Try replacing the cable - again if a no go, so it's not an interface/cable problem;
3. That leaves you only with the PS3200 itself as the possible at fault.
An external hardrive would consist of 2 main parts, the electronic board and the hard disk itself. The board seldom (if ever) fails. Its function is to provide conversion/interface from the SATA/IDE connectors of the HD to the out USB/Firewire. The HD more often than not fails. Most external storage uses a standard HD inside the enclosure.
Your possible options:
a. Claim warranty/replacement;
b. Replace the HD only;
c. Physically remove the HD and connect it directly inside a desktop either as IDE or SATA and run manufacturer's diagnostic and/or third party
d. Seek services of professional data recovery firms (if data/files are mission critical);
Hope this be of some help/idea. Post back should you need further information.
Good luck and kind regards.
have a SanMax HD-338-CB USB/Firewire External HD with a 160MB drive.
You then say
sometimes I have to reboot Windows XP pro 2 or 3 time before I see the drive using a USB 2.0 connection.
Fire wire is a different system with a different connector style- so it should not be in a USB port
or a USB connector should not be in a Firewire device.
Get you device and connections sorted
The desktop display simply puts up a device
it will not differentiate which USB or Firewire
