Any way of stopping it including the memory card socket in the calculation? Yep. Take the card out. He did say "empty memory card socket" Indeed, it always shows up as E: in task manager, even when empty. Short of disconnecting it inside the case, I can't make that E: go away. And I do use it every so often when I take videos and photos. |

Any way of stopping it including the memory card socket in the calculation? See if this doesn't help. https://support.microsoft.com/en-us/...storage-spaces If you've made a pool for storage space, this may be causing what you're seeing in Task Manager. I have no pools. Just a standard 1TB rotary hard disk and a camera card reader. Alright then... Are you referencing 'space used' or 'performance' Task manager calls it "active time" in the performance tab. In the processes tab (where it's annoying me), it's just a %. In Task Manager, under the Process tab where you are seeing x% usage, which processes are being used? You can click on the column label % and it will then show the most used processes at that time at the top. Yes I know I can sort them by most used. You do realize that the Performance Active time is not the same as the percentage of time the disk is being used by a Process. The % listed at the top of the disk column in the processes tab is identical to the active time % on the performance tab. To get a better visualization, look at the Memory process column and you will see how much memory is being used by each process. If you were to run a disk utility and view it under Performance, you would see the percentage of time the disk is being used. Also, the SDHC card should not be showing in the Performance tab. Agreed, but it's there and I'd like rid of it. If it is, then possibly something under "Storage Sense" where the SDHC card (and all drives show) and look at "More storage Settings" Change where content is saved. Anything in any of the categories show anything but "This PC (C" I'm not familiar with storage sense, please go into more detail. Did you look where I referenced to see if the SDHC is being used? For Storage Sense details - here's one reference: https://blogs.technet.microsoft.com/...18/08/30/9205/ I don't know what you want me to look at. Under storage sense, more storage settings, change where content is saved, everything is listed as C:, not the SDHC card. And I don't understand what storage sense has to do with the task manager. These are my results. My SD reader is a USB device with slots for SD type only. It's a USB2 device, not a newer USB3 device. The second picture shows a 512GB SSD on the end of a USB3 cable, which makes it a "portable" device, but I suspect it also has a "fixed disk" kind of status, which could be why it shows in Task Manager. https://i.postimg.cc/Yq1B77TB/SD-reader-empty.gif https://i.postimg.cc/rmv76ZJp/SD-rea...SD-on-USB3.gif I've made no attempt to capture benchmarks in there. Using HDTune, each device achieves 85-90% of its graph while HDTune benches the device. Since the SD is not shown in Task Manager, we can't tell from there how it's doing. HDTune says my SD card is doing 18MB/sec on read. It should do around 10MB/sec on write, but I don't plan on upsetting the contents (as the SD belongs to my digital camera). Since the last release or two of Windows 10, there is a slight amount of error in the HDTune bench, so some sort of temporal issue exists for software. If I really want to bench the devices, I'd be better off booting some other OS. A user can use "perfmon.msc" to chart performance counters, and there is a "disk read bytes per second" and a "disk write bytes per second" in there, if you need to see performance. No matter what utilities you happen to use on your Windows system, stuff can refuse to be counted, or can be double-counted, depending on circumstances. The performance counter system is not without its selection of "corner cases". The behavior of USB devices, can be affected by the RMB bit, and there are USB keys with RMB set or RMB cleared for sale. The Uwe Sieber web site has information on the side-effects of these design choices. The industry seems to have "shifted" a bit, now that Flash storage devices are getting larger. Devices in the 16GB-32GB capacity range, are where you might see the new RMB policy. Initially, I think some Sony flash devices were doing this. An SD reader could dabble in these practices too, so expect to see different behaviors on your new USB3 SD reader versus your yonks-old USB2 SD reader. At least for my reader, it stayed off the charts in the pictures. Only the SSD-on-a-USB3-cable was visible when expected to be visible. And that's the cable that happens to not handle power management states and flushing correctly. You can't win... Thanks for the in depth analysis - your computer is behaving quite sensibly. My SD reader shows as "removable" in the disk management console just like yours. How do I access the RMB bit etc somewhere? I'm assuming it's set correctly as my disk management says "removable", but maybe there's something else? |

Next time you insert an SD card it will appear in File Explorer with a drive letter as usual. And the drive with its letter should disappear when you safely remove the card. If you use subst /? you will see: Type SUBST with no parameters to display a list of current virtual drives. A virtual drive is a real "substituted" drive which you can access by its drive letter. Not the same as a phantom drive which does not currently exist on the system and cannot be accessed by its drive letter. |

Anyway, I can start up my computer never having had a card in the slot today, and the problem still exists, so it's not due to a phantom card left in there. I just inserted it, then ejected as you suggested, then physically removed it, then still got the above: Volume 4 E Removable 0 B No Media |

HTH, Paul You'll notice in my example, I use *no* equals sign. select partition 1 Diskpart uses selectors, to "focus" on one item at a time when working. The selection is maintained until you change it, or until you "exit". And no, your result is *not* normal. This is obviously a 32GB flash device, but I don't know why the partition entry is duplicated. DISKPART list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- * Partition 1 Primary 29 GB 0 B * Partition 1 Primary 29 GB 0 B ******* Note that, USB storage devices (in Windows), are only expected to have one partition. If you were using PTEDIT32.exe, you'd expect to see just one row in the table. When multiple partitions are present, Windows ignores partition 2,3,4 etc. Linux on the other hand, supports USB mass storage just like it was a hard drive, and you can have four Primary partitions in that case. ******* PTEDIT32 was available for years, as a download from Symantec after they acquired PowerQuest. Eventually, they removed their FTP server content, and we lost access. The only way to get PTEDIT32 today, is via this route. PTEDIT32 was considered a freebie, and there is no license key issue with respect to the "demo" package. Just unzip it and fetch out the PTEDIT32.exe file. While the main program is licensed, PTEDIT32 was considered a "utility" freebie. http://www.download3k.com/System-Uti...ion-Magic.html enpm800retaildemo.zip 23,776,770 bytes You can use 7ZIP to burrow into the file and extract the copy of PTEDIT32.exe. L:\enpm800retaildemo.zip\Setup\PMagic.cab\ PTEDIT32.EXE 503,808 bytes September 16, 2002, 2:24:48 AM In 7ZIP, it's under: C:\Downloads\enpm800retaildemo.zip\Setup\PMagic.ca b\ PTEDIT32.exe 503,808 bytes Once extracted, you run that as Administrator, or otherwise it won't be able to access the MBR and present a nice table of partitions. https://i.postimg.cc/ry1jSSnx/MBR-partition-table.gif If you don't run it as Administrator, it returns "Error 5", which is a permissions error. Note that it's intolerant of drives with Vista+ one megabyte alignment. However, for your 32GB SD card with the goofy partition problem, I'm hoping it will provide some evidence. PowerQuest put a lot of constraints on their software. Sometimes, you'd get lots of "warning" dialogs, when such warnings weren't necessary. The sucky part, was when their software "absolutely refused to work and quit". This is all done to protect your disks, but it still sucks, as there weren't really all that many geometry constraints on real disks. Much more creative geometries should have been possible, than popular tools supported in an easy way. In any case, that's a nice tool for reviewing some of my older disk drives. To see what is actually in the table! ******* In Linux, "sudo fdisk /dev/sda" followed by "p to print" then "q to quit" would give the same table of information. The beauty of PTEDIT32, is you could actually *edit* the MBR, which I've done a couple times. You can actually move a partition entry and put it back in spatial order. Like, swap entry three with entry four when the situation dictates. On WinXP, then you have to edit the boot.ini and fix the "path" to the disk partition to match (since the partition entry of your OS might have changed). That was a useful function in the old days. Not so necessary now, as modern tools don't do stupid stuff needing such fixes. Paul |

HTH, Paul You'll notice in my example, I use *no* equals sign. select partition 1 Equals sign or not, I always get "there is no partition selected". Strangely, doing exactly the same again, I now only get one entry in the partition list, and I have volume 4 for the card, which was previously missing.
