Data scrubing via via powered usb hub?

I had a problem with a usb ssd drive and one solution was data scrubbing via open bios and leave open over night with the usb conexted. I wondered if just leaving the ssd drive connected to my powered hub that has switched outlets would actually do the same?

My experience with my Self-powered 4-port Hub is that it needs to be connected to the computer so as to do any work with or on drives plugged into it. The ports on my Hub have switches which can turn any port off and stop any action on it. Or in other words the USB devices don't do anything on their own except those that can charge from a port like a cellphone.

Thanks but as I understood it the point of running in bios was to not have any activity with the SSD drive so it would do data scrubbing.

Is the "data scrubbing" to be done on the USB drive or the main/internal drive?

The BIOS is the Basic Input Output System, sets up the devices on the motherboard and provided information to the booted system, whether DOS, Linux, Mac or Windows, reads that information so as to know how to run things.

Don't confuse BIOS with Command Prompt/DOS mode. I still have bootable floppy disks from the '90s with MS-DOS on them, haven't tried to see if they work on modern motherboards. Back then DOS had to be installed before installing the GUI/Graphical User Interface or commonly called Windows or OS/2 but even then DOS would read the BIOS for the information needed and usually needed additional software drivers for some devices. Windows 95 was the beginning of merging the DOS with the GUI.

Its a ssd usb drives they wanted scrubbed. The information was to leave it power on with no activity hence the booting into the bios. The usb disk is said to have the data scrubbing as part of its firmware. My Dell laptop has interior ssd scrubing control I understand in the bios buts not used as the information was to boot to bios to keep it on but everything inactive so the ssd disk would run uts scrubing. Which is why I think just seeing it live via a hub would do it as well
I am now returning the ssd drive as faulty but was wondering if ever needed to do it in the future.

I just use Windows File Explorer to erase a USB drive or Disk Management to delete the partition/s and create new partition/s then format, usually sufficient for cleaning.

So basically someone told you that the external SSD needs to be powered on, and connected to an offline host to do its background scrubbing?

This part I don't understand. My experience in IT has been:
- Data scrubbing is something your host (OS) does, as a software function
- Data scrubbing is something your HW RAID or disk firmware does (maybe kicked off by an scheduling app)
- Some forms of scrubbing are "dumb", in that they wait until the drive has no traffic. If there's disk activity, it stops scrubbing since scrubbing robs your disk performance (it's reading data in the background)

I would check what docs are available for this particular drive, to confirm that's what supposed to happen. Scrubbing should run faster with no system load, because it's run as a low-priority task. The question is there some interval before the scrubbing kicks off, or you need some tool to send the SSD instructions to start scrubbing?

Keep in mind that USB ports and plugs have black centers for USB 2 and blue centers for USB 3. USB 3 is the fastest but the device and any cable used also has to be USB 3.

Garbage Collection or TRIM. Windows disk cleanup will normally perform TRIM about once a month. Your drive's vendor may have a Windows app to specifically tell your drive to do it immediately.

In Micron's instructions, they're basically saying you can't allow Windows to power down the USB ports (selective suspend) when Windows goes to sleep. Otherwise, the drive detects no host and stops garbage collection. Your PC might have Modern Standby as its power management, and may not allow S3 selective suspend to happen. If your PC is parked on the BIOS screen, it never goes to sleep.

As long as your BIOS reports it can see the external SSD, it doesn't matter if it's directly attached or thru a powered hub.
