Question eject Windows hdd + case usb

[cloudff7]

I use a USB3.0 enclosure case, brand and model Kesu 2530 and Orico 25PW1 black, i use 2.5" HDDs models and brands Seagate ST500LM030 and WDC WD10JPVX-08JC3T5, APPLE HDD HTS541010A99E662
In Windows 10 and others Windows there is an eject function (safely remove hardware) when this function is executed and the HDD + case does not appear in Windows, for example "E:" even with the USB3.0 cable connected to the PC on/case. After all this happened, my hand hit the USB3.0 enclosure case and it moved on the table. Did this hit cause friction between the 2.5" HDD read/write heads and the magnetic platters, scratching them?

I hope not. I would grab the respective drive utilities from the respective manufacturers.
Personally I use Hard Disk Sentinel Pro. I apologize, I personally don't know where to download a cracked version. Perhaps another member may help you or try a search of the torrent indexes.
Just because you eject a USB drive doesn't mean it has stopped revolving, all that accomplishes is making sure the buffer has written it's contents to the USB drive. In addition, unless you have parked the head, the drive is still as vulnerable. Good luck, it has happened to me a couple of times.

The EJECT SAFELY Routine has been in windows since the year of erm a long while back.

The routine turns off the data paths to and from any USB device as soon as the parsing is finished, thus when you decide to yank a drive out of a slot it doesnt send a spike into the ram chips. In the case of hard drives it returns the heads to the safe spot prior to removal.

Directly pulling a SATA cable out of a internal drive however will cause all sorts of issues as only Hybrid Drives carry a data buffer on board. Ive had drives that are wrecked and unusable after people have done that and nobody knows why they just seem to think they know more than others.

The Safely Remove Hardware is there as a buffer to stop damage.

0) My 2.5" HDDs are old from 2012/2013 models WDC WD10JPVX-08JC3T5, APPLE HDD HTS541010A99E662 and 2020 model Seagate ST500LM030. Do 2.5" HDDs from these eras accept Windows commands
eject Safely Remove Hardware and park the heads automatically after this command is finished and without the need to disconnect the cable from the USB3.0 enclosure case?

1) USB3.0 enclosures and cases use different chips and firmwares and brands and models. Do they have any relation or interference in the parking of the 2.5" HDD heads after ejecting in Windows while keeping the USB cable connected?

2) Do the Windows power settings have any relation or interference in the parking of the HDD heads when ejecting the USB3.0 enclosure case + 2.5" HDD?

3) After ejecting the USB3.0 enclosure case + 2.5" HDD safely remove hardware in Windows, the USB3.0 enclosure case + 2.5" HDD and the letter corresponding to the drive disappear, for example (E), at that moment the HDD heads are already parked?

4) Since what year did 2.5" HDDs of any brand and model + Windows version start following the command to park HDD heads after ejecting (safely remove hardware) in Windows? Even without disconnecting the USB cable from the enclosure/PC

Your Hard drives and Early USB sticks were the reason they made the eject safely routine. Make sure all buffers are clear and all drives are returned to safe spot. God I miss the old systems, you knew where you were with them.

Drive disconnects is the same as take out a USB stick, the letter goes with it. IF you wanting to read access and have shortcuts to different drives on the desktop, then instead of using the Letter system, give each disk a Name anything except Local Drive. My zip disks had programs installed on them and each was namedd and the desktop shortcuts were addressed to and run from the volume name.

eg, Sot01:dir1/JASC/PSPX.exe for the path and the run in Sot01:dir1/JASC/

The enclosure will be an arbitrary letter and will still allow you to access each drive placed in it. Just remember each disk needs to be named.

I have many doubts: some people say that enclosure case and Windows power settings and disconnecting the cables and cutting off the power have no influence on the parked heads of the 2.5" HDD after the Windows "safely remove hardware" eject command is completed and the letter E: disappears from the system; other people say the complete opposite and that the heads only park when cutting off the power to the enclosure case usb3.0+hdd2.5"; I'm confused.

I have an external HDD Setup, I use it as a portable to and from work. As soon as the data stream stops the head returns to its safe spot. The way most enclosures are set is to return safe immediately the data stops Ive dropped mine a time or too in a rush and it still works fine, contains a Hitachi 500GB drive in a USB 3 enclosure

If you are that worried I have a suggestion to see what actually happens. Use the drive, power it off, take out the drive, unscrew the cover carefully and lift the lid and see where the heads are. Depending on the safe spot in the drive they will normally be near the centre spindle. Replace the lid and set the screws back. That short a period wont cause massive issues unless you do it in the middle of a building site or somewhere dusty. Ive had drive to pieces on my desk and repaired spindles before and no harm comes to the drive. A quick blow with compressed air is a good plan.

It is surprisning how old the safe spot technology is, I can recall it being in a 5.25 80MB drive i had on an old 386 system and it wouldnt surprise me if it was older than that. Its what SHUTDOWN was made for

 

[Diguelo]

Generally it is assumed the Shutdown device, remove drive Letter and disconnect the data stream. in that order. I cant say I have fully diagnosed the Shutdown protocol with meters and leads to test the outputs, but one the item is safe to disconnect it can be unplugged. In the case of most if not all USB interfaces they have sufficient charge left in the system once unplugged to close the data streams inside them and protect the data within. I did mess with that back when USB sticks were new to see what would happen and and managed to wreck a couple of early versions without the right click on the icon in the tray. Where using the hard drive external units involving spinning media, they spin down after a short time but again if the plug is pulled and data is being passed in the stream the stream is immediately closed and the stream is removed from internal buffers and not written to disk. Early units would attempt to write the file which invariably would end in a single data sector trying to hold the rest of the file and failing.

For the past 10 years or so the USB 3.0 interface and 2.0 interface prevent stream writing once the power is gone and clears the buffers. Modern Hybrid drives tend to be more efficient in a disconnect as they use the large buffers to temporarily store the data and next time the power is applied the data is send to the drive, or so the manufacturers state. Again I cant say I have sat with a oscilloscope and watched it happen in real life, but it makes a lot of sense in the long run. Suffice to say If the light on the drive is on DONT PULL THE PLUG, the light means the data stream is active.

1) When the Windows "safely remove hardware" eject is invoked and the letter E: disappears from Windows, what type of command does Windows send to the 2.5" HDD and the HDD understands that it is time to park the heads?
2) Do the model, brand, chip of the USB3.0 enclosure case and Windows power settings have any relation to the parking of the heads of a 2.5" HDD after the Windows "safely remove hardware" eject command is completed and the letter E: disappears from the system?
3) In what year on 2.5" HDDs and in what version of Windows was parking the heads of 2.5" HDDs implemented after the Windows "safely remove hardware" eject command is completed and the letter E: disappears? even if the USB3.0 cable of the enclosure case remains connected to the PC/enclosure?

Shutdown was invoked back in the early days of DOS to safely park the drives heads in a safe and unpopulated area of a hard drive. Im going back to the days of RAM not being bought in strips and the only memory upgrades involve using a soldering iron and new memory chips being fixed to a board. IBM were the initial inventors of it because of their techs using Hard drives in Portable PC's the size of suitcases. Obviously as the drives are bounced around back then the heads weighed ounces not grams and the inital hard drives were size reduced version of the Platter cartridges about 18" across.

Today all USB enclosures have a buffer for data and prevent writing once the plug is pulled.

Earliest Ive heard of head parking on a portable Hard drive was an IBM own branded drive used in the portable system. This would be late 70's I dont recall the exact date but the need for it came from the need to transport data between offices initially. Data in the first instance used to be stored on rolls of tape that required skimming through an entire roll to find a blank space or a file that was needed. This used to be ridiculously slow and the tapes didnt last very long and the data frequently got lost due to indexing errors....

The floppy drive provided a simple medium although incredibly limited to transport data between computers, their shutdown was simple, lift the heads off the surface. Early hard drives involving a cake box of spinning platters and each having its own head set built into it became the first mass storage system where cartridges of disks and heads could be swapped once the machine was powered down, one cartridge removed, the other replaced etc.

Todays shutdown is much the same, once the data has stopped passing the heads are automatically parked in a safe place once the stream is stopped to prevent damage in transit. That is literally all the USB systems do from Version 1.0 through to USB 3.0 and beyond.

The fact that the USB medium is unplugged does not mean it is without power, each ram chip holds a charge to preserve the data and will remain active for years. Ive accessed data on an old USB 1 device after 4 years of not using it and it worked fine.

SO dont worry about the safety of 2.5" drives, the errors in unplugging were sorted out back when a compact hard drive fit in a 5.25" bay and you could remove it with a key and take it with you.

Thats windows shutdown routine. I usb system on a stick or USB interface is much the same. Preserve what data has been written into your media, close the ports, move the heads to safe and power off. The work of milliseconds

 

[Diguelo]

Oh and using shutdown in CMD in windows, always restart your pc afterwards


SO to answer your question in short, If it says safe to remove, its already switched off and just needs unplugging

My 2.5" HDDs are old from 2012 and 2016 and the models mentioned above have the ability to park the heads after ejecting to safely remove hardware even without disconnecting the USB cable from the enclosure case/PC? I don't know in which year parking the heads after ejecting in Windows was implemented, does the model, brand and chip of the enclosure case influence the parking or not of the 2.5" HDD heads after ejection in Windows and without disconnecting the USB cable?

 

[cloudff7]

Some people say that the hdd 2.5" heads park after ejection in Windows, other people say that they do not park after ejection in Windows and that they only park when disconnecting the USB cable from the enclosure case, what is the truth?

 

[cloudff7]

2.5" hdd parks or does not park the heads after ejecting safely remove hardware in Windows but keeping the usb3.0 cable from the enclosure case USB3.0 connected to the pc/enclosure after ejection?

or parking some cut power and physical disconnect drive?

 

[DVDR_Dog]

I ran across a thread in a Reddit WD sub that debates head parking. It's a sore subject however I stand by the last entry in that thread. As far what individual attributes drive and chipset combos may have, only the OEM knows for sure. I'd check the manufacturer's forums for accurate details on their drives.

Do the model, brand, chip of the USB3.0 enclosure case and Windows power settings have any relation to the parking of the heads of a 2.5" HDD + enclosure usb3.0 after the Windows "safely remove hardware" eject command is completed and the letter E: disappears from the system without disconnect usb cable after eject in windows?
