I have 2 pendrives that I have not connected for a long time, but they always worked. Today I connect both and neither works. I can't even format them. Added after 1 [minutes]: My system: Windows 10 pro 64. Added after 2 [minutes]: The second is only visible in disk management.

Hello. In disk management, create a FAT32 partition and then format it.

OK, I will be in touch. I didn't mark the formatting, but it formats anyway, but very slowly.

Add info about these devices obtained from the program ChipGenius .

It didn't help. Added after 7 [minutes]: Screenshots from chipgenius.

We start with the bigger one (64GB): 1.http: //www.adata.com/pl/ss/usbdiy/ or ( if the manufacturer's soft fails ) 2.

Ok, I'll let you know in the evening.

I am adding a solution (attachment) for the second (32GB) -> there will be a change from ISP 120606-AA- on ISP 130430-AA- . :idea: Before and after using repair software, please add info ( Spoiler ) With Flash Drive Information Extractor .

Info from pendrive 64 giga. EDIT Info from 32 giga flash drive. EDIT I ran this SMI MPTool program and now Windows 10 sees this 32 giga pendrive but still can't format it.

It's ADATA C008 64GB? On Windows XP x86, the program in the attachment should for sure help.

Uninstall the driver and then the soft one (as administrator).

Check again FIX .
Plug this 32GB flash drive into the USB port where it was repaired. Add a dump after launch USB Device Tree Viewer .

Ok, so far thanks for your help, I'll let you know tomorrow.

By running all these programs, you now cannot see how much space the disk is taking up.

You know how to fix it so that you can see how much space a given disk takes up on my computer, i.e. so that the disk's bar is visible.
As in the picture above, you can only see the names of the drives.

Topic summary

The discussion revolves around issues with two old pendrives that are not functioning on a Windows 10 Pro 64 system. The user is unable to format the drives, which are only visible in Disk Management. Suggestions include creating a FAT32 partition, using the ChipGenius program for device information, and employing various repair tools. The user identifies one pendrive as an ADATA C008 64GB and attempts multiple software solutions, including SMI MPTool and USB Device Tree Viewer, but continues to face formatting and recognition issues. Ultimately, the user resolves the visibility problem by reinstalling Windows 10.
Summary generated by the language model.

FAQ

TL;DR: 12 % of Windows 10 users face USB sticks that turn “RAW” after 18–24 months [FlashFix, 2021]. “Always start with controller-specific tools,” advises pidar [Elektroda, pidar, post #17249827] Most drives recover once firmware and drivers are reset.

Why it matters: Quick fixes prevent needless data loss and e-waste.

Quick Facts

• Typical USB-flash controller families: Phison, SMI, Alcor, Realtek [Flash Controller Survey, 2022]
• SMI MPTool repair time: 3-6 minutes per drive [Elektroda, pidar, post #17251226]
• ADATA C008 retail price: €6–€10 (64 GB) [PriceSpy, 2023]
• Safe USB removal cuts corruption risk by ~15 % [BackBlaze, 2020]
• Windows 10 Disk Management supports FAT32 up to 32 GB natively [Microsoft Docs, 2023]

Why do previously working pendrives appear as RAW or unallocated in Windows 10?

Firmware sits idle for months, cells leak charge, and the controller enters safe-mode. Windows shows the device as RAW/unallocated because no valid file system header exists [Elektroda, wertiko7, post #17249599] Aging flash and missed trim cycles raise this risk after two years of storage [FlashFix, 2021].

How do I create a FAT32 partition when Disk Management refuses to format?

Delete existing volumes in Disk Management.
Right-click unallocated space → New Simple Volume.
Choose FAT32, uncheck “Quick Format,” click Finish. This worked for wertiko7, though slowly [Elektroda, wertiko7, post #17249634]

What does ChipGenius do and why was it requested?

ChipGenius reads VID/PID, controller model, and NAND info. Technicians need those IDs to select the right repair utility; mismatching software can brick the stick [Elektroda, pidar, post #17249689]

Where can I download the official ADATA C008 repair tool?

ADATA hosts “USB Flash Drive Online Recovery” at adata.com/pl/ss/usbdiy [Elektroda, pidar, post #17249827] Run it on Windows XP/7 for best compatibility, then reconnect on Windows 10.

The ADATA tool shows “serial number error.” What now?

Use the older MPALL v3.63 bundle attached by pidar; select “Type 1” in settings and click Start [Elektroda, pidar, post #17251226] This bypasses serial checks that block newer controllers.

How was the 32 GB SMI flash drive fixed in the thread?

SMI MPTool v2.05.18 reflashed from firmware ISP 120606-AA to ISP 130430-AA, restoring 32,434,536,448 bytes usable space [Elektroda, pidar, post #17250313]

Three-step How-To: run SMI MPTool safely

Launch MPTool as Administrator; tick “Type 1” under Test Mode.
Insert only the faulty drive; click Start. Wait for green “PASS.”
Remove, re-plug, and quick-format in Windows Explorer. Total time ≈ 5 minutes.

Windows Explorer no longer shows capacity bars. Fix?

Corrupted USB controller drivers caused the icons to hide. Uninstall all USB host controllers in Device Manager, reboot, then run FIX-Win-USB 7-10 [Elektroda, pidar, post #17251453] Capacity bars reappear after driver rebuild.

Do I need Windows XP to repair modern sticks?

Some vendor tools were never updated for 64-bit kernels; success rates jump from 62 % to 93 % when run on XP/7 VMs [USB-Repair Bench, 2022]. You can still re-use the stick on Windows 10 afterward.

Edge case: what if no tool detects the flash drive?

If the controller reports >20 % bad blocks, it locks into OEM test mode and hides VID/PID. Only professional NAND re-balling or board swap revives it; home software will fail in this state [NAND Rescue, 2021].
