ok heres what happened -- My hard drive (Fujitsu MPF3204AH-20g) worked fine before I purhase the new hard drive (MAxtor 40g). First of all, I put my Maxtor hard drive as the master and Fujitsu hard drive as the slave. But my motherboard can not detect both of them. So, I tried to put Maxtor hard drive as master without putting Fujitsu as slave. So, my motherboard can detect my hard drive and It is working OK unitl right now. Then, I put my fujitsu hard drive again as the slave while my Maxtor hard drive still as the Master, but My motherboard still can not detect of them..Why??? Futhermore, I just put my Fujitsu hard drive as the master without putting Maxtor hard drive. In another word, there is just only my Fujitsu hard drive on my pC, but my motherboard still can not detect this hard drive. I has checked the connection/cable and jumper a lot of time eventhough I tried different cable and jumper setting. Unfortunately, it is still not wroking. Also, I tried to connect the Fujitsu hard drive to Promise controller card (add on card), but it is still not working (My Maxtor hard drive can be detected by Promise conntroller card before). So, can somebody help me in this problem becasue I have a lot of important stuff in my Fujitsu hard drive??? Help me,,,,

Are you sure the jumpers are correct?
I've had some Hdd where the jumbers where the oppersite of the what the sticker appearently indicated. One of these was a Fujitsu.

Thank for everyone answer my question in the short time. I really appreciate it. I tried to hhok up the hard drive to my friend PC and It still no response. Also, there is no sound coming from the hard drive. So, I guess I should say bye bye to my hard drive.

Try giving it a short,sharp tap with your knukles.
Did this to an hdd that was sitting for a couple of years and WHAMMO it workded!!
No problems with it in 6 months so far.

If you hear no startup whine, then you got the IDE cable reverse... make sure they line up for both of them, sometimes they need to be "flipped".

I would check the jumpers to make sure.

All default jumpers are set for Master... and Maxtor has a bad label for slave, master, or cable select.

My Fujitsus and Maxtors can coeexist just fine.

Even my two maxtors has to different labels for jumpers...

(I got a total of 4 drives, on different computers).

The MPF3204AH and MPG3204AH are known to be very broken in the electronics department. We had 100 drives replaced by our supplier. Once they break, they're permanently broken. I was Googling for HD firmware patches, but all I got was a huge list of pages describing the fault. Get your money back - your supplier should have been notified by Fujitsu. It's your *supplier's* job to sort this out with Fujitsu - not *yours*.
The 10G version of the drive has the same firmware. MPF- MPG3102 or something similar.

I too have a Fujitsu HDD which appears to have died & is not recognized by the BIOS. InterestinglY it is model MPG3102AH and so appears to fit in with the comments of Richard in this thread regarding these drives being duff. I thought at first that it was viral corruption of the MBR but as the drive couldn't even be seen by the BIOS I figured that the drive was dead! As the drive is just over 1yr old I guess I've no chance trying to return it to my supplier!

We now have over 20 PCs with this problem and are waiting for a probable 70 to fail. There is a confirmed problem with these drives (confirmed to our PC manufacturer). They have arranged replacements for all of ours. Hope this helps.
Sometimes if you are lucky it will restart for short periods after being left over night as the problem may be associated with heat!! You may be able to get some of the data off if it does start up.

I own a small computer shop in B.C. Canada and i was a big fan of the fujitsu 10-20 GB hdds in 2000 to 2001, now almost all of these drives have failed. so i started to send these drives back to fujitsu at my expence and they returned drives back however the drives sent back have the same manufacturing date. wonder if these drives will fail after 1 year? i am now avoiding fujitsu product like the plague!
total number of drives sent back is 14
total number of drives sold at that time 22
hope those other 8 hold out....

I too am having problems with the same models of FUJITSU drives. The drives all have 3 years warranty and Fujitsu will honour all the claims as they have also extended the warranty. If you supplier wont swap you drives you can call fujitsu directly and settle with them.
The problems is supposed to be only 2-4 percent of all the MPG3***** series drives manufactured in 2001-2003

These Fujitsu drive problems are serious, it affected many of our machines. But we managed to get the data off from them all by this data recovery company in London.Hope this helps you guys out there, they are at
