As everyone in this group probably knows, the IBM 75GXP family of harddisks are dying like flies on a hot summer day.

Can any of the products from MHHD assist with data recovery from these IBM drives in situations when the heads and media are undamaged ? ( these drives have sector servo-ID information stored on the HDC and not on the physical media which makes recovery rather tricky )

Can anyone in this group point to any software or specialist tools that are usefull for data recovery in situations when the bios does not receive a good status from the HD, and thus does not display the presence of the defective HD.

Good luck to MHDD and friends,
we will most certainly purchase any products that you recomend now and in the future.

kind regards from Sweden

Tony + Olga

Hi Mr. and Miss Smith, how are you both ?, I'm Jose Pinto from Brasil, the info about heads tools will be here since they are avalible.
About your problem with IBM hard drivers I think that you can take a look here: http://www.bvggroup.ru/PRODUCTS/HRT/hrt.htm
This is the only solution to IBMs problems that I saw till now.
Also the Acelab has some tools to IBMs and you can see the PC3000 specification here:

Best regards
Jose Pinto

Why you sure, that heads and media is undamaged?
IBM HDD's has a firmware in the mask-ROM in the DSP or in the external serial Flash-ROM, heads configuration information in the EEPROM and main microcode on the media platters.
When the main microcode or heads configuration in EEPROM is damaged, hard drive is only spin up the media platters and loads heads from parking area with one specific click (operational IBM HDD after that click is reading microcode with specific sound), or HDD is clicks by heads during some time.
Only in this cases, you need to use special software, like HRT or PC-3000 for restore microcode.
If the IBM HDD does not detects by BIOS, but already reading microcode from the media platters,
or only spin up the media platters without any sounds, or permanently clicks by heads, most likely
this is a hardware problem.
Most frequent troubles with IBM HDD's is a bad contact in needle-shaped connector under the PCB.
First of all, pins of this connector on the PCB must be thoroughly cleaned or resoldered.
Try to do this, resoldering of that connector very often helps to repair IBM HDD's.

Best regards,
Michael.

Thanks for the excelent advice Monolith, now i know a little more about the IBM 75GXP microcode.

I have allready ordered PC3000 so it will be interesting to try restoring the microcode and observe the results.

Thanks again - Tony

For "Monolit"

for hdd IBM that clicks continuously - rewrite the NVRAM an the click will stop after a short time. now what is to be done?, because the readiness is on but the click will begin again when any command for restoration is tried.

One of many solutions is SafeMode! But exist more others!

For "TheBeginner"

hi,
you were kind enough to send me a very interesting message a few days ago, but it seems to have been deleted from the BBS.

To you have an arkive copy maybe, i would like to save the information you gave me about the IBM 75GXP hd.

Thanks

Thank you, Thank you, Thank you....... TheBeginner.

The idea is very good, I just have to find how to do this safe mode setting, anyway this should leave the hdd in readiness immediately, but still don't exclude the click when a command is give for restoration. much more,...... the encrypted pwd that limits the commands by rejection, how important it is and how can be removed?

Please, check this out ==>> format_b@yahoo.com

Regards,
format_b.

PS: in curand o sa imi bubuie capul daca mai incerc prea mult sa descifrez mesajele tale "criptate".

Ce mesaje criptate? Daca folosesti SafeModul nu poti decat sa scrii sau sa citesti NV_RAM-ul. Nu ai acces la module. Daca e parolat trebuie sa alterezi continutul NV_NVRAM-ului si apoi sa-i suprascii USAG-ul si SECI!

ok, so SAFEMODE=AUTO SPIN DISABLE, I guess,

I will try this. - A bad NVRAM should bring the hdd after some click's in readiness, the rewrite of the two module should leave the hdd free of pwd (this if the rewrite is successful) and accept the commands for restoration. If the click will not leave the hdd in any condition can I say that the media is BAD or that the HDA is badly damaged? What percent of failing IBM hdd can be truly recovered?

Thanks in advance for the answer!!!!!!

format_b

PS: "criptate" - era un fel de a categorisi "One of many solutions is SafeMode! But exist more others!"

si eu ar trebuii sa le caut.......

The percent of recovery 99%.
