News: BIP91 seems stable: there's probably only slightly increased risk of confirmations disappearing. You should still prepare for Aug 1.

"-A" could also give you away. E.g. you'll have "G-Sense Error Rate" high then its a proof of a dropped laptop. Same things with "Power On Hours", "Power Cycles" and "Temperature Celcius" if you were fiddling with the computer.

I don't know how to read the information.  What does this tell you?  I really don't think the computer has ever been dropped or even bumped.

If that's saying I've turned the computer on and off 94 times, then I find that hard to believe.  I would expect something less than 20 to be the true figure - possibly even less than 10.  Unless it's counting when I close the lid and it goes into a suspended state, in which case I can quite believe the number.  I often have uptimes of over a week, and never reboot into Windows.

Edit: weird how bold spaces are narrower than regular spaces, messing up the table layout

The health is almost everywhere at 100%; 98% being the worst. If you really think that you haven't jostled the laptop itself, then continue to monitor the G-Sense counter every day or several times per day, until you'll identify the problem. Maybe its a window striking the table you keep the laptop on? Maybe you are slapping the lid shut sometimes?

You have 16 "Current Pending Sectors"; those are awaiting remapping/fixing.  This correlates with 15 "G-Sense" warnings: some vibration problem or unstable workspace.

Yeah, probably aggresive power saving. The Start-Stop count is at 100 with 94 power cycles.

What is going to last longer?
For current bitcoin{d,-qt} definitely spinning drive will last longer. As it is right now bitcoin{d,-qt} is a worst-case load for the solid-state drives:

1) it writes a lot of data that is never read: the database/log.* files
2) it has bad write amplification behavior: writes too small chunks of data that aren't properly aligned.

So you'll need either a spinning plater or a high-end SSD. Better ask your wife than me. Wink

- run "cmd" as Administrator
- run "chkdsk C: /f /v /x /r" and reboot
- take a look into the Windows eventlog under Application - wininnt

You can replace C: by every partition you have on that Laptob to check the filesystem intensively!
This is a bad advice. It gives you false negatives: chkdsk only scans inside partitions, but doesn't scan partition headers and various boot and recovery files.

Also chkdsk will be fooled with extended retry algorithms that are used in modern drives (with the exception of the most expensive enterprise drives). It will be silent about all the marginal sectors that are barely readable after many seconds of trial reads. You especially want to know about those in advance.

smartmontools are the best friend of smart disk drive users.

Sorry, but no ... on Windows this is the standard for checking filesystem problems. To diagnose further I would use a bootable tool from the HDD/SSD vendor. As SMART tools on Windows get often blocked or show wrong results due to IDE/SATA/AHCI drivers blocking the SMART commands. Also SSDs vendors use often non-standard fields in their SMART state, which are often not recognized by SMART tools.

I wiped Linux off my laptop before returning it to the manufacturer and reinstalled the Windows 7 MBR so it would boot straight into Windows.  Before sending it off I installed smartmontools for Windows to check that it shows the same error as its Linux counterpart, and it did.

I've never tried smartmontools on Windows before.  I use Windows as little as possible generally, but this time it worked for me.

Okay, it seems I should replace the hard drive. Now should I get a HDD just like it or solid state? What is going to last longer?

I back up data that I find very important often.

In a mobile device, which will get shocked more during normal use, I would go SSD. Nowdays I would even got SSD with normals PCs, but perhaps add a normal spinning HDD here for data-storage.

Edit: The point with the Bitcoin client and many writes to the disk is true, which wears out a SSD faster. But really, a current SSD should do it's job at least for the warranty period, which is 3-5 years + Bitcoin is soooo much quicker with a SSD!

most laptops do not have two hdds right, do any?

That's right, sometimes you can place a second disk where an optical drive resides, but I would not consider this standard. Get a decent external USB-HDD for backup and enjoy a SSD (that's what I do).
