4 out of 5 eggsGreat drive, but beware

Pros: This is a solid hard drive so far. It has worked perfectly for seven years or so. If you update the firmware, you shouldn't have any problems.

Cons: There is one problem that you need to watch out for that I only just recently ran into. This particular model of hard drive has a firmware flaw. This flaw means it's possible for the drive to write some log that can be written onto a sector it's not supposed to write to. Or something of that sort.

On startup, if this log writes to 300 sectors, or 300 + a multiple of 256, it causes an error, and the drive goes into a failsafe mode to protect itself. It permanently locks itself into "BSY", or busy state. This locks the SATA port and prevents your computer from being able to detect it. My motherboard's BIOS would get stuck in POST when trying to detect it, so I initially discovered that something was wrong when my computer didn't start. (And later isolated it to the hard drive by unplugging it and watching the conputer successfully start up.)

Once this happens, the only way to save it is to get a Serial to TTL or USB to TTL converter, and hook up your computer to three of the four pins in the hard drive's serial port. Then using a terminal program, you type in specific raw commands that tell the hard drive's logic board to delete the error and rebuild the partition. This also involves unscrewing half of the logic board and sticking a business card between the board and the head contact, instructing it to spin down, removing the cardboard and re-establishing contact, and instructing it to spin up again.

After all the commands have been entered, the drive should be fixed, and you can then plug it back into your computer and it should work again. Search google for "Seagate 7200.11 BSY error" for the specific instructions.

I'm going to be doing that process this week when my supplies arrive to do so. It's a really nerdy process. If you don't want to have to go through this, then you should update your drive's firmware to the latest version while you're still able to.

Other Thoughts: If you don't want to go through the long, involved process I described in the Cons section, keep this drive's firmware updated. Firmware updates should prevent the problem from happening. Otherwise, your drive may brick on startup and you'll need a technical, involved process to fix it.

5 out of 5 eggs

Pros: very fast reliable data security never crashes

Cons: a little heavy seems to run a little toasty even on idle could be my case idk

Other Thoughts: this drive is incredibly fast i got mine from a good will originally it was part of an external backup system but it was slow through usb so i made it an internal hard drive btw does anyone know what the actual capable write speed is in MB i know it is a sata- 2 3.0 gb/sec drive but i only get about 80 to 100 megabytes a second

1 out of 5 eggsDon't buy!

Pros: Nothing that Seagate's competitors can't match.

Cons: This drive suddenly died on me. Apparently, the forums indicate that this is a common problem with this series of Seagate drives. Fortunately, I had a good chunk of the data on it backed up, but I did lose a number files and cant recommend buying this drive. In fact, I seriously doubt I'll ever buy another Seagate product ever again!

Pros: ?

Cons: Had to pay $20 to RMA drive to Seagate after short use. Then had to RA 3 more times to Seagate. Then warranty ran out.

1 out of 5 eggs61 our 70 Hard Drives have failed

Pros: When Seagate came out with 32mb cache on it's 7200.11 hard drives, I never put anything else in any of my customer's computers. I insisted on it. I bought for myself, 70 hard drives. Why? The performance was excellent. NCQ, SATA II - 300mbps, 5 YEAR WARRANTY.*Seagate is the number one hard drive manufacturer in the world.**

Cons: *. Seagate WAS the number one hard drive manufacturer in the world, that is until, they for some reason, bought Maxtor. Maxtor was currently number one for bad sectors. Pure cr*p. Seagate lost their number one status due to THIS drive. What absolutely cooked their goose, is that the model with SD15 had a slightly less that 99% failure rate. The symptom? You reboot your computer and suddenly the BIOS and the operating system could not detect the hard drive. GONE. Seagate gave me zero problems when it came to returning the drive. I sent in 31 hard drives to their i365 data recovery center. I told them all I needed was access to the hard drive. The called me every time and told me that their were multiple bad sectors and that they could recovery the data for me. I thanked them for their offer, but said I would recover the data myself.

Other Thoughts: I returned 49 out of 61 hard drive failures. 60% of the "Re-Certified" hard drives have failed within the first month. I took the rest of my drives, recorded the model and serial numbers and through them in the trash. I WILL NEVER BUY ANOTHER SEAGATE PRODUCT. The failures were happening to most of their drives, but nothing like the ST3500320AS. I lost so much DATA, my customer's data and my customers business. I lost a lot of credibility although to my credit, I called every customer I could and replaced the drives befored they failed, for a reduced fee. Nonetheless, I WILL NEVER BUY, RECOMMEND, SEAGATE AGAIN. Western Digital Caviar Blacks became my preferred hard drive, again. I have bought over 150 1TB 1002FAEX with 11 failures so far in the last 3 years.

1 out of 5 eggsReally bad drive

Pros: Cost

Cons: High failure rate. I purchased around 20 of these over a 1 year period. Half of them failed. Had them replaced under warranty. 3/4 of the replaced drives failed. Replaced again. 50% failure rate on those drives. 4 years later and I am still having failures on replaced drives. Some have been replaced 3-4 times under warranty. Clearly there is a design defect in this model. I haven't had these kinds of issues with other Seagate drives, but then I tend to avoid Seagate if at all possible because of the experience with these drives.

2 out of 5 eggsGenerally Good Drive But...

Pros: Bought two of these for a RAID about 2.5 years ago. The first drive continues to run flawlessly. Second drive failed after 1.5 years and was replaced with a Seagate Certified Repaired HDD. The Repaired drive just failed. Now, if the first drive had failed, I could generalize and say that all these drives are unreliable, but the first drive continues to run fine. So, generally, these drives seem to work at least 50% of the time very reliably and without a hitch.

Cons: By the same token, I've always had a lot of faith in Seagate and expected that a Certified repaired drive would be much less likely than an off-the-shelf drive to fail. Why? Because once the drive fails, I expect a tech to check every part on the drive and make sure that it runs as well or better than one coming off the assembly line. Maybe this was a fluke, but I find it very disturbing, particularly since I bought the 500GB size because it was reputed as more reliable than its higher density cousins. Now, I'm thinking of switching over to WD's black line which still offers a 5 year warranty. As I read reviews on Seagate lately, I see more and more negative language on a brand that I once would have staked all my data on. If anybody at Seagate sees this, let me emphasize that, after a drive fails, the replacement really shouldn't.
