Hi Guys, I am trying to recover a 128GB memory USB-drive with a IS903 controller. The controller does not seem to work properly. the memory chip is labled "43010Y018946 128G" or "4301DY013346 128G" or something similar, but it appears to be relabeled. Can anybody help in recoverring the data from the memory chip? Thanks and best regards kdMK1973 ChipGenius does say about the memory chip: Description: [K:]USB-Massenspeichergerät(NAND Flash) Device Type: Mass Storage Device Protocal Version: USB 3.00 Current Speed: High Speed Max Current: 304mA USB Device ID: VID = 1F75 PID = 0903 Serial Number: 16110956000040 Device Name: USB DISK Device Revision: 0001 Product Model: NAND Flash Product Revision: 1.00 Controller Vendor: Innostor Controller Part-Number: IS903-A4 - ??ROM??

Yes. Chip-off method should give good result for this controller. |
