Hi I have a seagate 7200.11 750gig drive SD04 which will not spin up.

Here is the background. I had another drive same model SD15 which needed a firmware update. The SD15 had bricked itself and I used the previously discussed method to revive it with hyperterminal. I then proceeded stupidly to update the firmware and didn't remove the SD04 drive from the computer. The Seagate firmware update app began to update the SD04 rather then the SD15 drive. On the screen it said reading data so I shut it down thinking it was just reading info off the SD04, but it wasn't. The SD04 will no longer spin up. When I connect to it with hyperterminal I get the following info. Is there anyway to recover and fix the boot loader?

Control+Z displays the following:

TetonST Boot ROM 2.0

Serial FLASH boot code checksum failure!


if I type in ? I get

Boot Cmds:
DS
AP <addr>
WT <data>
RD
GO
TE
BR <divisor>
BT
?
RET

if I type in GO the drive responds

Any help would be greatly appreciated.

Thank you,
Jeff

You lost the firmware and are stuck in the bootloader.

Is there any way to get the firmware loaded from the bootloader screen? Any idea why the firmware for the SD15 would have run on the SD04? When I checked the serial for the SD04 it said it required no update.

I have the updated SD15, are the firmwares compatible?

I don't know if firmware can be uploaded by serial port. If it can you need something better than Hyperterminal.

Specialized tools can do this, so you should get help from a pro DR agent. He probably has image file that belongs in the flash.

Personally, I don't have these tools and the data, so I would find identical drive, read its flash, and copy the image into the chip.

Only copying flash from other SD04 is dangerous since there is unique adaptive data stored in flash rom. if you overwrite it from other disk you lose it and make recovery much more complicated and you may even further damage your disk. you need to reflash your drive with SD04 firmware but with ORIGINAL adaptives. i suggest not powering on this drive anymore and going to a pro. it should not be that expensive.

Which updater package did you use? Windows? CD ISO?

Do you have a link to the update?
