Failure!

[rameez]

Hello gurus ,

I have recieved many drives about 300 pcs Maxtor 4R080L0 drives which report themselves as Generic 10gb and show capacity of 10gb these drives have 2 heads and one is disabled from the zone and head map as well , I extended the drive upto 40gb it scans in victoria OK , but all these drive report failure on computer <they have been checked on DELL> . I have checked the whole firmware i found no errors .
My question is Why does this failure occur then ?
Any comments will be helpfull .

Thanks .

Hi!!

HPA ON??

For me the new fw. doesn't fit. Try another w/different rom. Also I suspect ata ovl or simply 1f and 95 mods.

I got the same drive today fully working , its model number was same as my drive but its ROM checksum was different so i rewrote module #39 that changed the ROM SA but still there was failure , that got me mad i backuped all modules of the OK drive and rewrote to the failed drive but still same . Any suggestions !!

how about trying to adopt another method

[Shortscurcuits]

Did you try Maysoft's capacity restore tool?

[rameez]

Shortscurcuits ,
Capacity has been restored by rewriting the 1F module .

HDD Pig ,

What other method are u talking about ?

[Shortscurcuits]

See if you can find 1F & 95 with correct checksum. I did a Maxtor a while back replaced 95 with different checksum module and head 5 stopped working on the drive, until I found a better module with the right checksum. Then it worked fine.

May be something similar here, these are 2 head 40GB platter drives right?

[rameez]

yes there are two heads in this drive i have checked the module 95 and also rewritten it with the same working drive found no effect .
As i told u before i have wrote all the modules and the group modules and now i hooked it up on selfscan after the selfscan finished with success still DELL reports it as iminent failure now the drive is scanning 100% not even one defect what should i do ?

rameez, rewrite the SMART data. Anyway I was the first pointing out 1F and/ or 95 failure... please send beer, 2 barrels (one for the 1f idea and one for not giving the credit LOL) . It is possible that after SS the SMART data remains intact so the DELL , relying on SMART ATT reports the "imminent" failure.
Check in this drive the number of relocated sectors, pendings etc. and you'll see something strange.
This is gonna cost you another barrel

[rameez]

I will check the SMART att again but i have already reset the SMART parameters using pc3k pci that way i can be sure that its not SMART problem .

[Shortscurcuits]

Rameez are these Maxtor drives or re-issue by maxtor for another manufacturer.

Also do they report imminent failure on another non Dell PC.

[rameez]

Yes they have been issued to a company name Generic whos engineers have made 80gb drive 8gb and spoiled the whole SA .
And this drive reports failure on most of the machines i have checked .

[Shortscurcuits]

Rameez do they have a rom chip on PCB. Maybe try to swap PCB and see if it changes.

If smart ok in PC3K on disk maybe they screwed something in the boot code on PCB.

Or find correct checksum LDR & mods re-write all mods, clear P & G list & selfscan.

If smart shows OK but reports failure something is either corrupt or not correcting.

Since you are refurbing these this might be the only way to go.

[BlackST]

Rameez do you have a photo of these drives ? (label, pcb ?)

[rameez]

I will post photo of the drive .

Shortscurcuits ,

Good idea i will change pcb and post results here .

hi

i think maybe good that you test hdd with powermax or seatools
