Smart Data Recovery
Kym Wash
How can I reset the SMART results so it does not register previous results. My reason is that I was testing the hard drives closed together on a closed case. This made one of the HDD fail the Airflow Temperature reading.
After opening the case up (Which lowered the Temp of all drives 10 degrees Celsius in 5 minutes) and then separating the drives a bit more (3 less degrees) All results were good but since the Airflow reading failed in a previous reading, it always shows as failing.
Actually there is a way to reset S.M.A.R.T. data. You only need simple rs232 to usb converter (uart to ttl) and a few cables attached to hdds diagnostic interfaces. (it's on the right side of sata port, 5 or 4 pins) You must conect RX TX and GND cables (and power cable of course :D) then power on HDD and connect to it with putty or hyperterminal (linux can connect with it's own terminal i guess)for example for seagate drives:for 7200.10 and older baud rate is 9600for 7200.11 and newer is 38400
That's why it says "failed in the past", not "failing now": you did just barely touch the max-temp threshold. Note the attribute display shows "normalized: 50, threshold: 45, worst: 45". (These are 0..200 normalized values like for any other attribute, not raw Celsius temps.)
A better SMART software UI would show you the current and max-ever temp. e.g.
smartctl -a /dev/sda or smartctl -x /dev/sda (-x prints all available SMART and non-SMART data it can get from the drive, including a temperature history log if the drive has one, with an ASCII bar graph.)
The software you're using looks like it's only showing the current temp, which is slightly below the threshold, but it's not going to hide the fact that the drive was out-of-spec at some point in the past.
You could certainly justify ignoring that momentary high-temperature, if you really did correct it in minutes. But you won't (or shouldn't) ever be able to make the drive itself lie about the fact that it was over its rated max temp for some time, and thus the attribute did fail in the past.
You can configure smartd to ignore any given attribute so you can still get a useful notification if anything else crosses a threshold into officially-failing territory.: smartd.conf(5) says:
-i ID [ATA only] Ignore device Attribute number ID when checking for failure of Usage Attributes. ID must be a decimal integer in the range from 1 to 255. This Directive modifies the behavior of the '-f' Directive and has no effect without it.
This is useful, for example, if you have a very old disk and don't want to keep getting messages about the hours-on-lifetime Attribute (usually Attribute 9) failing. This Directive may appear multiple times for a single device, if you want to ignore multiple Attributes.
If you drive has these extended attributes, you can show someone that the time spent outside of allowed temp was very short (if that's the case). Presumably if you were going to modify the SMART data, you'd just have done that and removed any mention of it being out-of-range ever, but obviously you can't 100% trust any data from a 2nd-hand drive that someone's trying to sell you.
A stupid thing about SMART is that it permanently stores one time transient things that did no damage at all. I had a drive that recorded a power failure in its SMART and forever after the computer would warn about the SMART data indicating "impending drive failure" simply because of a power outage caused by someone driving into a power pole. No idea why that specific power failure got recorded by SMART when I've had many computers and many drives experience power failures without recording them as an "error".
Hard drives have spare space for recovery reasons. The recovery happens automatically. Recovery tools only remap physically bad sectors to this spare space. Once remapped, when a read or write occur to a bad sector, the drive turns the access to the spare space, and hides the error.
Many of the unrecoverable drives that we receive, have been KILLED by such utilities mostly for the simple reason that a failing drive, needing to be kept TURNED OFF, has been massacred by an absolutely USELESS repair (killing) process
A sector that can not be read from is commonly referred to as a bad sector. Sometimes re-reading the sector multiple times results in a successful read. In some cases the disk may reallocate this sector immediately: The contents of the sector are stored in a spare sector, and the bad sector is taken out of service. The disk itself keeps track of these sectors.
On a disk that is going bad, you do not want to force the disk to do thousands of reads on bad sectors. So, you do not want it to do what Spinrite does. The stress from the re-reads may very well be the last push the disk needs.
Also, based on this article, re-reading sectors over and over, and doing long reads over and over, does not result in reliable data at all. It produces random bytes. There is zero point to it. 2000 times zero, is still zero.
This is why all people that are serious about data recovery, including data recovery labs will try to clone a hard disk first. They will employ software, or a combination of specialized hardware and software that first gets the easy to read data. This is often the bulk of the data. Areas that are hard to read will be processed last. If needed such combinations of specialized hardware/software can even avoid using a specific disk head or avoid using corrupt firmware.
Such sectors could not be read but since no data could be recovered from them they are pending reallocation until data is written to them. In such a case you can run a DiskPatch read/write surface scan after which the sectors will be reallocated. You can use Spinrite for that purpose as well. Run some more surface scans to make sure the disk is stable. Monitor the disk closely over the next few weeks (SMART). To do this automatically you can install a SMART monitor.
What follows are the notes I made while running SpinRite on various SATA
drives. In all cases I used a Dell Optiplex GX280 with the A08 BIOS,
which is the latest BIOS for this system. These notes are not in order
of importance.
2) When #1 did work, using the arrow keys or number keys would sometime
work, and sometimes make the display choice window close. There seemed
to be no rhyme or reason for what the arrow and number keys did.
Well, and THAT surprises me. The support team is indeed one guy (used to be, called Greg). But from what I have observed they do follow up on support requests and they do returns/refunds. What I also noticed is they change their support email every year: so right now it probably is suppo...@grc.com. Hope this helps.
I concur with Joep that SpinRite is at best useless and at worst data destructive. I say this as someone who has used SpinRite during the MFM/RLL days of the late 80s and early 90s. However, after HDD manufacturers switched to voice coils, embedded servos and IDE interfaces, SpinRite instantly became irrelevant.
One thing it is useful for IMHO is recovering floppy disks. I have had it fix weak sectors and allow copies. Yes the head touches the disk. But it also could be consider cleaning said surface. Followed by a floppy drive head cleaner, then a re-read attempt has worked for me.
Maybe. Of course it supports FAT so it can reclaim clusters marked bad but a format would do. I would have to look up what either BIOS or DOS interrupts would allow it to do with regards to ignoring ECC (long reads), perhaps it could do something there that for example a windows based surface scanner would not be able to do. All the supposed interaction with firmware is moot with regards to floppies of course. So, yeah, maybe. But still a far cry from all the wild claims the websit/Steve makes with regards to hand drives and SSD.
Obviously there are data on the 2 mirrored disks that I do not want to loose. Is there a (safe) way to retrieve them (before sending the disks to a data recovery company) ?
Some people suggest to intialize the disk AND use a data recovery software.

Yes, it is possible to recover data from a physically damaged device. Data recovery experts have the tools and expertise to repair or replace damaged components in order to retrieve the data. google However, the success of the recovery depends on the extent of the damage and the condition of the device.
To prevent future data loss, it is important to regularly back up your data on an external hard drive or cloud storage. Additionally, implementing strong cybersecurity measures, such as using antivirus software and regularly updating passwords, can help protect your data from potential threats.
