Hi,

I'm little bit tired, still looking for LBA0 error solution. Does anyone know how to solve LBA0 problem in Seagate SCSI drive? Anyone know how to fix Translator without expensive tools?

Cheers,
Krzysztof

On first, u should know wich problem has that unit checking Sense Key, Sense Code, Qualifier code ,sounds etc, Could be another problems like PCB, Heads, Spindle, or SA Translator but the first its identify the problem, if u want do find solutions by self, start to understand the protocol used on this units , but this is not for newbies, need knowledgment and know how hdd works, if u dont have that "outsourcing" its u solution

Regards

I can assure you that you won't find the solution to this problem without paying for it. If it's a Cheetah family drive then there indeed are a series of SCSI commands that will re-generate the translator. However, this information is not something you will find given freely on this forum.

Have same problem. If it's a Cheetah family drive , you must renew it's firmware , by special utility .... from com port . official site offer to write special letter with your problem , after wait , after they MAYBE send to you normal firmware which you can rewrite if your drive is working , anyway its wouldn't help .... the best choise is serch this utility ,( last time was given by ingeneer from PC3000 company for seagate home class ), and reset firmware , or if it not more quarantee rewrite ,

Mr. Krzysztof , would you used raid 0, 1 or 5 with your seagate ?

you dont need to write the FW.

Hi,

At the beginning thanks to everyone for the posts.
Following the instigation of more experienced users, I bought software which theoretically removes the LBA0 problem on these SCSI disks. Unfortunately did not work.
I tried a few times, sometimes the program showed an LBA0 error sometimes showed the "off line" status.
Probably, only solution in this case is replacement ROM to the identic PCB.

SCSI Seagate ST336753LW

Absolutely not the solution! This is an issue of translator corruption. Has nothing at all to do with PCB.

Hi,

It was not my idea.
I wrote to the software manufacturer, which I used, and they replied me:

"Please change ROM to a good pcb , fix this hdd "off line" error. Soft can fix "LBA0", not support fix "off line""

Have they lied to me?

Best Regards,
Krzysztof

Thats not the solution believe us, Medium error at the most cases are detected like Sense Key 03h , Sense Code 00h, Sense Qualifier 00h, its a problem on Engineering Cylinders , when u had PCB problems u will get Sense Key 02h Not ready

Regards

Seatools available from Seagate can upgrade/download firmware/microcode,change/adjust capacity and format scsi disk drives. You can probaly still find the ST336753LW firmware/microcode file with extension .sea,.lod,etc. out on the internet.
Post something if you can't and I'll find the firmware. I don't know the revison of your HDD so I don't know if it's vendor firmware from Dell,EMC,etc. so I assume the HDD came directly from Seagate. Hopefully after reload of the firmware the hardware re-initialization will adjust/fix any motor and/or servo positioner problems for what I assume is a Drive Offline problem.

yep LBA0 and sense message will be medium corrupt etc. Off line not ready is another issue like SA corruption or bad heads......

Could be worth swapping the flash over to another PCB... You need the flash because it has configuration modules that are 100% required for a decent recovery.

All went well until I plugged the drive in.

Not sure this is timely info as the Seagate ST336753LW has been around a while, but wanted to share a recent experience because this forum has helped me in the past:

Had a new spare pair of ST336753LW drives on the shelf for several years. Finally installed them as Drive 0/1 this week RAID1 in a workstation with an onboard AIC-7901 controller.

First boot after installation was fine, but subsequently Drive 1 gave sense key 02h, code 04h, qual 02h (not spinning up).

Searched extensively online for suggestions. Had a problem with a different drive last year and knew about Hydata but didn't buy because of high cost. Plus, not sure those tools would have worked on last year's problem drive or the current one.

Frustrated by the fact that the drive did work for a short time and then quit, and that it might be out of warranty having been purchased a while back though not yet used, tried several things over the course of many hours.

What finally worked was to temporarily make the problem drive Drive 0 and the remaining good RAID1 member Drive 1 (J6 jumper block). Also temporarily rearranged the SCSI bus (cable) so that the problem Drive 0 was at the end, with the terminator.

Then went into the SCSI configuration area (for this controller, CTRL+A) and looked at the RAID1 drives. Because they were now reversed, both were listed as members but both had ID 1. Obviously not correct. Came to the tentative conclusion that the RAID management utility cannot dynamically update when drive IDs are changed. Didn't proceed further.

Put drives back to original Drive 0/Drive 1 configuration and rebooted. All drives spun up during the SCSI bus scan. (In addition to the RAID1 drive pair, there is a 3rd SCSI drive in this system.)

Went back into the SCSI RAID configuration area and found everything back to normal, except Drive 1 showing as degraded which was expected.

Repaired the array and we've been good to go (so far).
