Short expert follow-up that builds on what and already noted.

Because the adapter shows up empty but certain microSD cards connect only briefly on two different PCs, this is most likely a card-or-reader hardware issue (or a bad/unsupported card format) rather than a one-PC Windows setting. Start with non-destructive checks, then move to targeted recovery only if you need the data.

  • Try the card in the phone or a camera first. If the phone reads it, copy the files off before doing anything else.
  • Open Disk Management (diskmgmt.msc) while the card is connected. Note if the device appears without a drive letter, shows as RAW, or is unallocated. Do not format the volume if you need the data.
  • Check Device Manager for USB or disk errors; uninstall the entry for the reader and rescan. Try a different USB port (avoid unpowered hubs).
  • Swap the physical reader/adapter. Use a known-good dedicated USB card reader rather than a phone-style adapter—cheap/old readers often fail or lack SDHC/SDXC support. Also check any lock switch on a full-size SD adapter.
  • If data is critical, make a read-only sector image first (use a tool that supports error-tolerant imaging such as ddrescue on Linux or a Windows raw-copy tool) and work from the image with recovery tools like TestDisk/PhotoRec.

Why it briefly appears then disappears: failing cards or controllers often enumerate then drop out when errors occur, and a corrupted filesystem can cause Windows to unmount the device. Because the Transcend card worked but the others didn’t, the simplest next step is to test the problem cards in another reader or phone; if they still fail, replace the card or use a recovery/image workflow before attempting repairs.

Check your drive letters setting under 'My Computer / Manage' , if the letter that were assigned to the card previously are now used by another device, then it could cause the SD card not to get a letter, hence not showing up under My Computer.

hm. as i understand problem isn't in this. if to connect the adapter without memory SD card -all'll be ok - the adapter will show as empty usb-device, but with the memory card it was showing only for one second and then dissapear from "my computer" window.
Could the problem be in the data, which is stored by card?
But i also have another microSD (kingston 1gb) , wich is also from mobile phone - and this one also wasn't showed up in the explorer (my comp.)

but the third card (transcend 1gb) was showed up correctly.

Originally my first card which i need to connect to PC was in complect to sony erricsson mobile phone , so i think that the problem can't be in disparity between microSD adapter and memory card models.

May be your adapter, I am just guessing here, but if the reader is of an older type and the cards are newer such as SDHC type, then it could cause read problem, but seriously, looking at your post, the problem dont seem to have an logical answer. What I would suggest is to use teh card reader and the 2 problem cards on a different computer, if you hit the same issues, then it could narrow down to the card reader or even faulty cards, otherwise, its a software/Windows problem on your PC.

the problem is same on the second pc (the first one - win XP the second -win 7)

Ok, this narrowed down the possibilities, if the memory card works in a camera or your cellphone, then chances are your card reader is not totally compatiable.
