    What maintenance do solid-state drives require?


    By Fred Langa

    Windows 8 and 10 are fully solid state-drive (SSD) aware; Win7 is less so and Vista, not at all. Here's what that means, and how to maintain SSDs on all Windows versions. Plus: Getting older Windows versions to run on PCs designed for Win10 ó without running into a morass of driver issues and related trouble.

    The full text of this column is posted at windowssecrets.com/langalist-plus/what-maintenance-do-solid-state-drives-require/ (paid content, opens in a new window/tab).

    Columnists typically cannot reply to comments here, but do incorporate the best tips into future columns.

    To see whether TRIM is working properly on your SSD-equipped Win7, 8, or 10 PC, open an admin-level command window and enter the following:

    fsutil behavior query DisableDeleteNotify

    Windows will respond with DisableDeleteNotify = 0 if TRIM is working.

    If you get a different result, or if youíre using Vista (which lacks a built-in TRIM function), youíll have to use a TRIM utility provided by the manufacturer of your SSD. Check your SSD OEM/vendorís support pages.

    To summarize: Any current, good, general disk-health tools work fine on all disk types; only the older Windows versions require any special actions regarding SSD maintenance.
    DisableDeleteNotify = 0 only means that TRIM is enabled on the OS, it doesn't mean that it's actively using TRIM on the SSD.

    To enable TRIM on such drives probably needs a change of drivers for the SATA/IDE channels as some drivers can't use it (or allow the SSD firmware to be updated), I tend to stick with the default MS drivers.

    This is just not true. As satrow points out, you need a driver that supports TRIM.
    See this post for a real test of TRIM.
