The Solution for Seagate 7200.11 HDDs

Recommended Posts

I realize I'm being cautious. Most likely I will eventually proceed as if this is the LBA 0 problem.

Well, you have anyway a 50% probability ;):

http://en.wikipedia.org/wiki/Flipism

More seriously, matters are much more complex than that. :ph34r:

Among all the PC's existing, the DELL's (and particularly their BIOSes) have been traditionally a PITA, it is perfectly possible that it is that particular machine's BIOS that behaves like that (i.e. that same disk connected on another PC shows 0 size instead of unknown)

But it is also well possible that your disk suffers from an altogether different kind of issue. :(

Before going on, I would try on another machine and/or have a look at the drive from either Victoria or hdat2, or if you have a Linux distro available, check it with hdparm it is possibly not the case,/it is unconnected but, example:

http://forum.hddguru.com/viewtopic.php?t=11040&start=175

hdparm can see a LBA0 drive as having 0 sectors (LBAsects=0) but it will in the end say it is "unknown".

My Seagate Barracuda LP ST32000542AS has a little different problem (but i think this should be the correct solution). I dismounted my goflex desk cause the sympthom was: hard disk boot up correctly and windows recognize it, if i try to get data from it (not all data) the base begin to flash like the hd is sleeping. I can get the first data i wrote in it (for example, the seagate programs); i thought maybe hddregenerator could help me to get data so i tried to run it, i got some Delay at the beginning and when the scan reach 3,2 GB (or 3,6 GB, i'm not sure) it says "Device is not ready". Should this tutorial help me to solve it? I think maybe i should apply solution for busy fault

This thread is NOT about the LP model and NOT about ANY other problem but the two specific ones mentioned and it is related ONLY to the 7200.11 model.

It makes NO sense WHATEVER:

  1. to post about your issue on this thread
  2. to even think that something that may work for ANOTHER issue on ANOTHER model may be of any use for your issue (which is NOT BTW the BSY/busy state)

My seagate 7200.11 responds to ctrl / z only when connected to the pcb disk. When I disconnected pcb I fail to connect with hyperterminal. Why is this happening?

Possibly it is not in one of the malfunctioning cases we are talking about (LBA0 or BSY).

A "normally working" 7200.11 terminal is accessible with the PCB connected to the disk (obviously), cannot say if a "normally working" one is also accessible when the PCB (powered) is detached from the actual disk (and/or one of the two sets of contacts are insulated), but I think it should as well. ;unsure:

I'll have a problem with the electric mass?. Will I be able to use a disk pcb other similar characteristics to recover my disk is damaged if its pcb I burned?

Why should you have "a problem" (as long as you connect properly GROUND to ALL equipment involved)? :w00t:

Review point #7 of READ-ME-FIRST:

NO. :w00t:

There is a sticky EXACTLY for this doubt:

http://www.msfn.org/board/topic/150215-dont-even-think-of-swapping-pcbs-on-720011/

You CANNOT exchage PCB's on "modern" hard disks (including the 7200.11).

As a matter of fact you can, as long as you transplant properly the ROM, example:

http://stores.ebay.com/hddSupplier/PCB-Swap-Guide.html

Please consider how if you are here asking about making a PCB swap it means that you ARE NOT able to do it (CATCH22 ;)) and you WILL NOT be able to do it until you will put together a not-so-basic amount of knowledge and experience in soldering and more generally in electronics repairs.

As said your problem (whatever it is) seems like being NOT a BSY or a LBA0 (but you haven't provided yet ANY meaningful detail/info to confirm or deny this hypothesis) :(.

I have two similar hdd one that works and the other does not. When I connect the hdd that works with the screw pcb hyperterminal communication with hyperterminal is perfect, when I separate the pcb, this is not connected to the terminal. In the case of the failed disk I can not get connected to hyperterminal in any way. Always using the same ttl converter. Because I can not ge achieve connection with the hyperterminal. Apologize because my English is very bad.

I want to know why the pcb is not connected to the terminal without being bolted to the hdd. From already thank you very much and sorry for my ignorance

The diagnosis is:

  • *something* does NOT work in the disk that is not working :w00t:

There are 3 (three) possibilities:

  1. it is a BSY <- in this case it is possible that the procedure to exit BSY state may work
  2. it is a LBA0 <- in this case it is possible that the procedure to exit LBA0 state may work
  3. it is *any* other malfunctioning different from BSY and LBA0 <- we have NO idea of any procedure (if existing, and if existing without needing specialized proprietary software/hardware) that may work

I hope the above is clear enough. :unsure:

Hi to all...

I "fixed the drive" but now it's showing bad sectors,also i have updated firmware,but again hdd sentinel shows bad sectors,i dont know what to do next...any solution,or it's electronic on hard drive.

Hard drive is Seagate Barracuda ST3500620AS 500GB,Firmware was HP24,i updated to SD1A.

Sorry for bad English!

These are "separate" issues.

The BSY or LBA0 issues are the result of *something* that causes the disk firmware to enter a *loop* of some sort.

The "cure" is a method/procedure to exit this *loop*.

Bad sectors may develop for several reasons that have nothing to do with the above (and that cannot be fixed).

The fact that you updated the firmware (which is never recommended and definitely NOT suggested in the case of flashing a Seagate firmware over a HP one :no:) may be part of the cause of the bad sectors, but not necessarily.

That disk is now "gone for good", if it has developed bad sectors (and continues developing them).

If you have on it data that you wish to recover :ph34r:, you should have NOT updated the firmware, and in any case now you may look for professional recovery services.

If you managed to recover the data on it, it's time to throw the stupid disk in the dustbin and buy a newer one :(.

Thank you for reply...

On HP24 firmware was also bad sectors,first problem was that bios dont see the drive,but i was able to install system on it,and then i run HD Sentinel,and see about 2000 bad sector,later i found this solution,but first i updated the firmware to SD1A,i was hoping that bad sectors are gone,but not.Then i try the fix of BSY and LBA0,it was successfully,turn on hard drive,run sentinel,healt was 100%,performance also,then again updated firmware,and later,bad sectors return...When i run surface test it's all ok,no sign of bad sectors,but sentinel show's it...

I was hoping that I would solve the problem and I was persistent, but I no longer have the nerves!

I have no data on it,now i'm selling the drive!

Wait a minute.

If BOTH the Seagate (and NOT any other tool) Diagnostic tools (Seatools) run the short and long test successfully, then your disk is fine and HD sentinel is wrong.

I think the last time I worked the tests, they were ok .. then why would the sentinel showed bad sectors...

I'll do it test again during the day,and take screenshot to see...
