if the problem happens when connected to usb 2 only - then the system does not supply enough output power on the usb - that is max 5 V at 0.5 A = 2.5 W MAX<br />
you need to use a <b>pôwered</b> usb hub then

Thanks, nobus. Makes sense. In this case, all my ext HDs have their own power supply.

Glyph sent me an RMA. Drive still on warranty. If they can't make it perfect, they said, they'll send a new one. Thanks for taking an interest in the question.

Running a Win7/Pro/64. Have two HDs attached, one a Glyph Studio 2T. Noticed recently the blue power light on Glyph has twice switched to a red/pink blinking light during work. Manual says indicates disk problem, but even in red I can access disk and files. When I turn off power button, then turn on light is blue again. Cannot reproduce conditions under which it twice had turned blinking red. Two notes: Glyph is a USB 3.0 connection. Computer if a Dell 980 with USB 2.0 ports. (System will not accept a 3.0 card). Have a G drive 2T 3.0 also connected and is running fine. Also disk is shared on a two-machine intranet. Its NTFS with only 62GB data on it.

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
