[fingers crossed]

The current build now offers a 10-band EQ, if you're so inclined....

Cool beans... thanks.

Blimey! Now what?

Microsoft DiskPart version 6.0.6002
Copyright (C) 1999-2007 Microsoft Corporation.
On computer: <my computer>

DISKPART> list disk

Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
Disk 0 Online 233 GB 0 B
Disk 1 Online 59 GB 0 B

DISKPART> select disk 1

Disk 1 is now the selected disk.

DISKPART> clean

DiskPart succeeded in cleaning the disk.

DISKPART> create partition primary

DiskPart succeeded in creating the specified partition.

DISKPART> format fs=fat32 quick

FAT32 is not supported for the selected volume.
Please select a different file system type and try again

I've also tried formatting the cleaned disk from Windows Explorer, where the two choices are NTFS and exFAT. This is on a Windows Vista platform, if that makes a difference (I know that utilities from mixed versions of DOS did!).

And now from the CMD prompt:

C:\Users\<me>>format f: /FS:fat32 /q
Insert new disk for drive F:
and press ENTER when ready...
The type of the file system is EXFAT.
The new file system is FAT32.
QuickFormatting 60905M
The volume is too big for FAT32.

Maybe I need to specify a cluster size and, if so, how big a cluster?

Try clean all instead of clean. will take longer.

I haven't personally used it but I've read a least a dozen accounts of others here and on the Rockbox forums successfully using guiformat. You can read more from the developer here http://www.ridgecrop.demon.co.uk/fat32format.htm

Thanks for responding. It appears that part of my issue may be that I've been trying to format the card from Vista. I have an XP machine at work and will try it on that box tomorrow (the card is at home). Also, I see in the Rockbox forum that someone successfully used Partition Wizard on their SDXC card installed in their Clip.

If at first you don't succeed...........

[Syndrome]

Ah yes, Partition wizard, I was going to look it up when I got home today. I used that to do my 64gb card for a samsung galaxy tab 2. It is now in fat32.

[jagdriver]

Using the adapter, I plugged the card into the slot on the side of my monitor (XP machine at work) and tried Diskpart. Nothing. I then downloaded Partition Wizard and tried again; it didn't register the card partition. Hmmm.......

I then put the card and adapter into a USB adapter I always carry and plugged that lot into a free USB port on the back of the PC. I then ran Partition Wizard and—lo' and behold—the card was recognized straight away. I then chose to format it as FAT32, clicked the [Apply] button and PRESTO... my PC was engulfed in flames a foot high!

;<) Sorry.... I formatted as FAT32, clicked [Apply] and PRESTO! The card is now formatted as FAT32 and I've successfully copied files to it. Now I'm finally able to create the daily DAP of my dreams. OK, maybe not of my dreams, but I'm a L-O-N-G way from my do-all, homemade boombox mashup circa 1970 (think Felix the Cat's magic bag), coupled with an orange crate full of homemade Dolbyized cassettes.

So was the key (or trick) the adaptor or that you used one of the back USB ports?

[jagdriver]

I suppose the first trick was to use a USB adapter, as this WinXP PC doesn't have a card reader (other than the one built into the side of the Dell monitor). Mine is similar to this:



I think any USB port would do; I used a rear port because my adapter is too wide to fit in one of the front ports.

The biggest trick was in using (the free) Partition Wizard; it was extremely easy to use from the get-go. Without having to read any destructions, the only trick here was to intuitively click the [Apply] button after I had selected [Format] and had chosen FAT32.

[Syndrome]

Ya. That apply button got me first time i used it as well. caused me to try other programs until i noticed it. in my defense i was a bit tipsy when i did my 64gb card.

[jagdriver]

Right. I almost closed the app after selecting the format, thinking that all was good to go. I would have been disappointed, but then maybe the app is smart to have reminded me that, "Hey, you formatted a volume... do you want to apply the change?" I'll never know now, but am glad that I noticed and thought to click [Apply] before closing it.

Useful thread - thanks! I am trying to get my Sandisk 64G microSDXC card useful for my rockboxed clip zip.

I have a windows 7 lenovo x220 laptop. Via the SD slot and windows explorer, I didn't have an option to reformat the card using fat32. But using using Partition Wizard, I was able to accomplish the following:

1) create partition:fat32, 64k, 60902.67 MB (59.47GB)
2) format partition: fat32, 64k (not sure if I needed to do both)

I could then copy files to it etc.

BUT it is not recognized when I put it into my rockboxed clip zip, or into my Samsung Tab2, or into one of the USB slots (with adapter) on my laptop, where it says that I need to format the disk before I can use it

I select "format disk", it is only allowing for a capacity of 27.4G. And if I do then reformat to 27.4G fat32 64k, then my rockboxed clip zip does recognize it. But, I'm missing a lot of GB

Any ideas? Thanks!

Edit: I found and tried Ridgecrop's fat32format program, and allowed it to use the default allocation unit size (32000 or something I think), and now my clip zip is recognizing it, and has even played a song off of it. Looking good!
