I've had a clumsy day which culminated in
knocking my 250gb Lacie mass storage device
off my desk.
When it's plugged in, a regular beep and
slight grind (like it's "stuck"). No recognition
by my computer.

Assuming I'm destroying data,
don't think I'll be turning it back on.

So did I simply blow it?
Is there an inexpensive way
to recover the data?

In the grand scheme of things,
these are trivial problems, got
backups of almost everything uber important.
Plus some people don't even get a square meal,
and so on.

Just lost a lot of footage, pictures,
a good chunk of music, and damned near
every BFN audio in an archived folder. Sad

Data Recovery from LaCie 'Big Disk' USB / Firewire external hard disk drives

**It's important to avoid taking any action that could compromise the integrity of data, especially with LaCie servers. At the first sign of data loss, immediately shut down the failing device and contact a data recovery engineer.

All external hard disk devices (such as the LaCie Big Disk) are infact one or more standard IDE hard disk with a USB & / or FireWire interface surrounded by a metal or plastic case. If the external hard drive is seen in Disk Management but does not have a drive letter, what happens when one tries to assign a drive letter? If successful, then all is OK. But this will probably not happen. The loss of connection may be sufficient to damage the boot sector, or Track 0, of the external hard drive. This is the reason for the same behavior in other computers. Re-format the drive. Specific files & / or directories become inaccessible and disappear. In more severe cases, the entire drive becomes inaccessible and disappears.

Possible overheating - The drive enclosure contains no fan to cool the disks and therefore, especially in hot conditions, the failure rates of these devices will be higher.

Disk geometry and operating conditions cause failure due to bad sectors
LaCie Big Disks frequently use Maxtor or Western Digital hard drives - get info on specific failures of Maxtor hard disks and specific failures of Western Digital hard disks.

If you use Win Vista:
Maybe using OS format, which can not be recognized by VISTA >> format to FAT32

If you open case:
Wear a ground strap/ground yourself out by touching metal case of something earth grounded. Check power input. Check voltages. Check fuses. Check for broken wire, solder joints or IC pins.

Mechanical:
Check for proper mechanical actions. Something moved? Sewing machine oil is best for small mech parts. Don't use silicone based lubricant.

use disk management under admin tools, in Control Panel if you use winblows, even if its not seen under "My Computer", All drives attached to your computer will be listed there problems or no problems. Also,depending on how new your Mo-Bo is, the BIOS may also see the external drive listed. NOT saying this is a fix, just a note to say it still may be seen and listed w/ a problem there.

Its more than likely toast from such a drop, especially if its not being recognized in winblows, external noises suggest The Head Actuator is whacked or, FUBAR'd

Data can be recovered, but only by pro's w/ pro equipment which means Pro $$$$

hope this helps
