Re: Lacie 250GB external HD (Error Code - 1309),

Files over 4Gb in size cannot be copied on to a fat32 formatted disk

you need to reformat the drive to NTFS to copy files over 4GB
(but this would involve putting those large quicktimes elsewhere
since reformatting your drive will wipe it)


make disk images of your quicktimes using a program like dropDMG, or the disk utility in your applications folder.

then use split & concat to split the dmg files into smaller chunks, copy them over then recombine on the target drive

Re: Lacie 250GB external HD (Error Code - 1309),

For systems prior to OS X; error -1309 fileBoundsErr: file's EOF offset mark or size is too big If your disk is formated as HFS rather than HFS+, you can get this error. For OS X; Error 1309 is a file bounds error. In other words there is some discrepancy with the file's size or end-of-file marker, or some variation on this. This sounds like a read error not a write one i.e the problem lies with the original file. Now, you may ask, "How do I make it HFS+?"... You would have to reformat the drive to change the formatting to HFS+ (Extended). Backup anything you can't replace on that disk, then use Disk Utility in your Utility folder to reformat the disk. Use Extended formating option.

Lacie External Drive won't turn on (blue Light doesn't go on)

Inside the LaCie D2 250GB (300770) external harddrive's case, is a 250GB IDE (PATA) harddrive that is 3.5 inches across in width.

A desktop computer sized harddrive. (May be a Western Digital WD25000JB)

The harddrive plugs into a small circuit board, (Bridge board), and the circuit board has a USB port on it.

Using this Western Digital Passport for an example,

Scroll down to the second photo, and left-click on it. The case of the external harddrive is shown open.
Inside is a 2.5 inch laptop sized harddrive.
An aluminum tape strip covers the small circuit board, attached at the back of the harddrive.

The second photo down on this page, shows you the small interface circuit board, that the harddrive plugs into, with the aluminum tape removed.

(Another design has wires coming from the small circuit board, to an interface the harddrive plugs into )

It is this small circuit board that goes bad in a LaCie. QUITE common.


1) Obtain a 3.5 inch IDE external enclosure
2) Remove the 3.5 IDE harddrive from the LaCie's case.
3) Install the harddrive out of the LaCie into the external 3.5 IDE enclosure.

An example of a 3.5 IDE (PATA) external enclosure,

Freezes up During Backups

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.

Constantly getting write data to media errors

If you're using the MS Backup utility, it's creating .BKF files which are very large (1-2GB+). Your external hard drive uses a FAT32 file system, which has a limitation of 4GB per file. If your backup files are over 4GB, it won't copy. It probably worked on your 250GB hard drive because it was formated with NTFS and not FAT32. You'll need to limit the size of your backup files to 4GB or less, or use a different utility that has file-size splitting options.

Lacie 250GB Hard Disk is not being recognized by PC (Windows XP)

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.

Recognized - but no mount

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

Lacie 320 GB Hard Drive acting as if full when it's not.

Simplest solution: back up the data on the drive and repartition it (which will wipe it). Otherwise it sounds like it could be a problem with the file tree or structure of the drive, the configuration files could be corrupt, some program could have stored temporary files in a hidden place that cannot be deleted without making the program delete them, etc. If you are on a mac, spotlight Disk Utility and use it to repartition. If you are on a PC use the search thing from the start menu and find a program called disk management (or something similar to that, you'll know it when you see it.) external drives are annoying. i kick mine into the wall periodically for good measure.

Lacie 250GB External Hardive to be used between a PC and a MAC

Be carefull when moving data from Macs to Windows etc. Your best bet would be to start again. It should work if you get your friend to put the data on the drive & copy it directly to your Mac. From there, you can safely copy data to the PC, but may have trouble accessing that same data after the PC has had it.
