The issue has been corrected by Seagate. New drives do not have the problem.

I do have the same problem with a 500GB Sata. Was working well, then on boot its gone. Tried the disc on another PC, but the same problem. Mine is a Seagate. All my data is on this drive and backup not working.
Is there a solution?

Further to my previous post, there is a KNOWN ISSUE with Seagate 500gb and 1tb 7200.11 drives relating to the firmware. Symptoms include not being detected in BIOS after reboot (without warning) and wrong sizes being indicated in BIOS. Check the Seagate website for more information. If your drive is under warranty, as mine was, you should be able to get it repaired by Seagate (with your data intact) free of charge providing it is the Firmware issue.

Good luck, hope this helps.

jimbojones -

I have 500 Gb Barracuda 7200/11 that after 9 months this morning decided not to recognize the drive. POST stops at "detecting drives."

WHERE on Seagate site did you find that? I found firmware update but nothing about fixing existing problem.

I assume you contacted them. Is there a phone number for Seagate Service?

Oops! That's your site link.

I purchased the drive last November and registered it. It is an OEM drive but used to build a PC (my son built it for me) so it is not OEM as it would be for HP, Dell, etc. On the warranty site it shows as being in warranty until 2013, parts & labor.

I will report back and let everyone know how they respond to my pleas. :-)

Just wondering...

Would it be possible to access the HDD if placed in external drive enclosure that has eSATA and USB output and use the USB output and connect to another machine? Anybody try this?

Or is the "no detect" problem a drive problem and not an unique SATA issue?

SUBJECT: ST3500320AS Barracuda 7200.11 SATA 3Gb/s 500-GB Hard Drive

I come back from holiday 2 weeks ago, switched on my computer and after the BIOS posted, nothing happened. My boot drive is a Seagate Barracuda 500GB 7200.11, firmware SD15. I googled this thread and concluded that it must be a sudden firmware issue causing the “breakdown” of my hard drive (I could still hear it spin up to speed but my BIOS reported no hard disk detected. I checked the power and SATA wiring with my other hard drives and these were detected as usual).

I contacted Seagate support Tuesday, TNT came at Seagate's expense to pick up the unit Thursday. Arrived at Seagate Amsterdam service centre Friday. Received message same day saying that it was a firmware issue and they were on the case. Unit arrived back on Tuesday. Put the drive back in my PC that night and it booted into my Windows XP OS as if nothing had ever happened.

Conclusion: very disappointed and worried that drive developed this issue in the first place but first class Seagate service thereafter. I use three identical drives and have now updated the firmware for the remaining two. Hopefully this will be the last time this type of issue arises.

Hope this helps.

I would try the following: check the power and data cables. Unplug them and try a different SATA port and or power cable.

Good Luck

thx, jimbo. but I just noticed on the label of my hard drive that it is a Seagate Barracuda 7200.10 400 gb.
may this one have the same firmware problem?

I also tried to put drive into an external drive enclosure as well as several different machines, changing bios settings as I went. No combination worked. The drives are shipped with a bad firmware issue that has a bug in it. This needs fixing before any machine will recognised the drive.

Options available to get the drive flashed with a non bug ridden firmware are either:-

1) Seagate ( best option if they will do it )
2) Data recovery expert ( Costly )
3) Do it yourself ( using numerours guides on internet)

If your hardrive is bricked as a result of the firmware issues around seagate drives check out the following link.

If you need help then let us know

I shipped the 500 Gb drive last evening per Seagate instructions.

This morning I received email that drive received.

This afternoon I receive email stating that they determined it was faulty firmware and was corrected.

Soon thereafter, I received email that they backup my data and will retain for 14 days (in case I have problems with the drive) AND that the "media" has been shipped back. I was given UPS tracking number.

Amazing service!

Thanks for the help! I wish you success: with Seagate or with the 7200 fixit procedure in the link above.
