Question about Computers & Internet

6 Answers

I plugged a Lacie hard drive into my mac book pro and the light on the hard drive and on the power cord was flashing on and off but the hard drive icon would not show on my computer. i unplugged it and plugged it back in a number of times and restarted the computer and it still didn't work. the next thing i knew the hard drive was completely dead and there was a very unpleasant burning smell coming from the spot where the power cord goes. HELP!! what has happened. I have data on this hard drive that i absolutely cannot lose.

Dear Martin, dont mean to flame you... But good luck finding a basement forensic data recovery tech for $150. Try $150-300 per hour and you are probably looking at a minimum $500+$2000 to recover data on a drive that may not have a single problem with it... I guess it depend on how deep your pocket book is... Your Lacie caddie may be the only problem. And powering up the drive is not going to do more to it than the data recovery tech, because that is the first thing that he is going to try. He is going to see if the drive has a problem... I do suggest testing on a junker computer if you have one... or better yet, buy a new $20 dollar caddie and try swapping the drive. Then you have the protection of the caddies fuses in line to your machine.
I do and have done forensic recovery, and most of the tools that I run go for atleast a few hours, and you will be billed accordingly. And the clean room, clean box is a fallacy. Most data recovery is done on a countertop and a one pass image read is created and recovery works on the image created. Clean room excuses are usualy brought up to justify the thousands of dollars you get billed for. Often in drive failure the bios of HD board is damaged, and all you need is a ace flasher to reflash and repair.

I agree with MJS_1[Martin]
rgconley2007 , If the data is so vital, important, u can't live without, then u must pay for the repair and data recovery.
The only other thing as to [SILVERADOMAN's] SOLUTION, I would try it on a 'winkie-dinkie' computer recover the data, copy or "move" the entire Directory\folder from Lacie h/d to the "winkie!",then use a cd-r/w to place info on cd''s

I STRONGLY disagree with both these solutions, as they are
potentially extremely dangerous !!

1) There is no way to determine what caused the hardware failure
within the external drive. (without further testing)

It could have started in the power supply, possibly
damaging the hard drive's internal controller, or...

it could have started in the hard drive's internal controller,
overloading and damaging the power supply.

2) In either event, connecting the suspect hard drive internally
into the main computer may damage that as well, or cause
unnecessary data loss.

3) The first commandment of recovering data from a bad hard
drive is NOT to try to do this your self,

because any erratic head behavior due to a bad controller
and/or physical damage will casue permanent data loss.

4) The best solution is to send the hard driver to a professional,
who will first determine if the damage is electronic,
mechanical, power supply and/or the controller board.

These professionals maintain a large stock and variety of
spare hard drives, from which they borrow parts to temporarily
fix your drive and recover your data onto CD's.

5) In the case of electronic failures, they will install a good
controller board and power supply into your hard drive to
recover your data.

(This seems to be your problem)

6) In the case of mechanical failure, they will open the sealed
platter enclosure, an either replace the complete head
assembly, or place your platters into another drive.

(This requires clean room or clean box facilities, and
special tools to make sure that the heads don't stick/
atomically bond to the platter surface during removal.)

7) They also have special software to recover files from
partially damaged disks.

8) Professional/ enterprise services can get very expensive,
but a local "basement" technician should be able to
recover your data for $150 or so, depending on the
drive model.

Who knows what the root cause of the powersupply in the LaCie's failure was? Be observant when putting the drive into another drive enclosure, planning to back up immediately, and note whether it spun up or not; sometimes a motor coil fails, and then (if and only if you don't have a backup) you're stuck asking a recovery service shop (cleanroom et al) to bail you out. I mean, it sounds like something shorted last time, somewhere.

If your PC still works sounds like the circiut board in the hard drive enclosure may have can take apart the external hard drive enclosure and install the hard drive into the PC and use as a second hard drive( but be sure to jumper the slave pins on the second drive).Your PC should recognize the second drive and then you can click on my computer and the dbl click the second drive and see if your data is there.

I can't see my mac lacie ext hd on windows pc! Any software available? Thanks in advance

you can always goto , there you can find
all available drivers for their products , ?mac both

either an Ultra ATA or a SATA and even the new solid state , I have never heard of just a mac HDD
a good rule of thumb is to trouble shoot from the beginning like when a light doesn't work the first

Will erasing my LaCie ext HD impact any files on my Mac Book?

It will only effect thoes stores on the external harddrive. You will have to check the contents of the LaCie drive and see if it has any files you typically access from your Mac Book. Other then that no it will not effect files stored on your Mac Books drive.

My Mac suddenly cannot find my Lacie external storage device. I have turned off, unplugged, restarted... etc. and it is still not finding it. The Lacie seems to be on, at least the blue light is...

A continuous flashing light on a Lacie drive is a notification of a problem. I do wonder if the light is flashing the same if the drive is plugged in to the Mac or unplugged.

Lacie external drives tend to have power-supplies which become weak/bad. Most users replace the supply and it will work again for awhile until the supply dies again. Try bringing the drive to a retail dealer with Lacie drives -ask them if you can just test your drive with another power-supply (if you do not have another). You can also try calling Lacie, it's always slightly possible they will be aware of this problem.

Alternately, IF the light is only flashing when the drive is plugged-in to the computer, try using a different USB or Firewire cable.

Having Problem with both LaCie hard drives being recognized on both macs

Try to connect to another computer, and see if it recognizes the drive. If Not, you can dismantle LaCie and take the disk out.

Connecto your disk to another external box (USB or Firewire) so you can have access to you data.

Lacie drive won't mount

I solved the problem. It was a power supply problem. It seems after searching boards on the net, this is a common problem with the lacie hard drives. Just replace the power if your hard drive is clicking and not mounting. I think many people must be throwing the drives away thinking they are lost when it is just the power supply. Try this first before trashing it or spending a lot of money on data recovery programs/
