kicked out ext hard disk cable while writing > end to end errors :(

[Long Hot Summer]

Hi!

I accidentally kicked out the cable of my external USB hard disk while it was writing. Now end to end errors are 99. Is that something to worry about? Because if it's caused by power loss, the 99 is maybe not indicative of the drive's state, but just because of that incident. I have no idea about this value before this happened.

The drive has 827 power on hours.

Auslogics: Bad health, B8 end-to-end error value = 99, raw data=1; status: age exceeded
CrystalDiskInfo: same as auslogics but says Good health and doesn't mention age exceeded
Seatools: DTS passed, short generic test passed
Windows error checking: No errors

I would appreciate any help!

This 3TB Seagate DM series drive is the worst of the lot. The heads ride so close to the platters that even the slightest bump will result in disastrous results.

If you value the data at all, now is the best time to seek professional data recovery assistance. These drives fail fast and hard, the more you power it on, the lower your chances of getting your data recovered.

If you don't value your data, you can try to get a full sector-by-sector copy of the drive with a program like ddrescue. I'd be happy to assist remotely, if needed.

If your time is more valuable than the data, just send the drive back to Seagate under warranty and hope you have better luck with the refurbished drive that they'll likely send back.

Edit: For some reason I read it that you were saying you are getting read errors throughout the drive. That said, just backup your data as quickly as possible and send it back under warranty. As I said, these drives are horrible for fast fatal crashes.

"End-to-end" errors mean that the drive detected that the data in the write cache waiting to be written was corrupted while waiting. This is included in the SMART data so that you can tell if the hard drive's cache RAM is faulty.

In your case, it could easily be due to a single episode with a power problem - especially, if power was lost and then came back a fraction of a second later because of a loose wire.

In my case, it was about 5 seconds before I plugged the cable back in. Could this still be the cause?

Yes - the electrical effect is substantially the same as a loose wire. The drive lost power suddenly while writing. The drive brand really is not relevant - that would happen to any brand of drive.
